Best Contractors for Adding a Basement or Attic Bathroom (2026)

The research in brief

The consensus leader for a new bathroom addition is Bath Fitter, named by 4 of 7 platforms (57.1% share) at an average listed position of 3.5 and a best position of 1. The strongest alternative for a distinct buyer need is EcoFlow LLC, named by 2 of 7 platforms (28.6%) at an average listed position of 3.0 and a best position of 1 - it is the only qualifying entity whose public scope explicitly covers new drainage runs, sewage ejector systems, venting, and permit coordination for below-grade bathrooms. Seven platforms were studied: ChatGPT, Claude, DeepSeek, Grok, Perplexity, Kimi, and Gemini. The principal limitation is that only two entities met the two-platform eligibility rule out of 46 unique entities named, and every platform rated Bath Fitter a weak fit for this exact use case, so the ranking reflects discovery frequency rather than demonstrated suitability for ground-up bathroom construction.

The Consensus Ranking

Questions explored

• What are the best bathroom remodeling companies for a new bathroom addition in 2026?
• Which contractor is ranked first for adding a basement or attic bathroom, and how many platforms named it?

The table below is the complete consensus ranking. Only two entities met the two-platform eligibility threshold, so the table has two rows. Platform mentions count only ranking-discovery mentions, not the number of platforms that later completed a fit assessment.

Bath Fitter ranked first because it was named by more platforms (4 versus 2), even though its average listed position (3.5) is slightly worse than EcoFlow LLC's (3.0). The ranking rule prioritizes platform mentions before average listed rank.

Which provider fits your needs?

Questions explored

• Which bathroom remodeling company should a buyer choose for a basement bathroom below the sewer line that needs a sewage ejector pump?
• Is Bath Fitter or EcoFlow LLC better for a new bathroom addition when new drainage and venting runs are required?
• Which contractor should a homeowner choose for a new bathroom addition if they want one company to manage framing, drywall, tile, and finishes?

The two qualifying entities serve different versions of the same buyer need. Neither is a full turnkey answer for every project.

1. Bath Fitter

Questions explored

• Is Bath Fitter worth it for a new bathroom addition, and what are its main drawbacks?
• What does Bath Fitter cost for a bathroom remodel, and does that price include new plumbing rough-in?
• Can Bath Fitter install a sewage ejector pump or run new drainage for a basement bathroom?

Verdict. Bath Fitter is the consensus leader by platform mentions but a weak fit for a true new bathroom addition. All seven platforms that assessed fit rated it weak. Its documented core offering is a fast retrofit over or in place of an existing tub or shower, not a ground-up addition involving new drainage, sewage ejector systems, structural work, or new venting runs ^[15]. It may be considered only when the room and rough plumbing are already substantially prepared and the buyer mainly needs a tub, shower, wall system, and selected fixtures.

Why it ranked here. Bath Fitter was named by 4 of 7 platforms (ChatGPT, Claude, DeepSeek, Gemini) at an average listed position of 3.5, with a best position of 1 on DeepSeek and Gemini. Its higher mention count is what places it first despite a weaker average position than EcoFlow LLC. The ranking reflects how often platforms surfaced the brand during discovery, not a judgment that it is the best contractor for this use case.

Best suited for. Replacing or converting an existing tub or shower where rough plumbing already exists; a basement or attic bathroom that is already substantially roughed-in and needs a tub, shower, wall system, or selected fixtures; homeowners prioritizing low demolition, fast installation, acrylic wall systems, and a product warranty.

Main strengths for the use case. Potentially useful after a bathroom shell and rough plumbing already exist ^[24]. Fast, low-demolition acrylic tub, shower, and wall installation model, with installation advertised in as little as one day ^[15]. Free consultation and customized estimate are advertised ^[25]. Published limited lifetime coverage exists for specified Bath Fitter-manufactured acrylic products ^[28]. The company states it uses professional, licensed, insured, and background-checked installers ^[25].

Main limitations. No verified standard service for a completely new basement or attic bathroom ^[24]. No verified public commitment to new drainage runs, sewage ejector systems, venting, permits, inspections, or full addition coordination ^[24]. The one-day installation claim concerns the retrofit system, not the entire construction process ^[15]. Acrylic wall systems may not satisfy buyers seeking conventional tile, full custom masonry, or broad material selection ^[16]. Warranty coverage is product-specific and does not clearly cover all addition-related labor or third-party systems ^[18]. Independent coverage states Bath Fitter does not offer toilet, sink, or flooring remodel services ^[58]. Water seepage between the old tub and the new liner is a documented complaint theme, and warranty disputes are common on negative review platforms ^[56].

Pricing or cost summary. Bath Fitter costs $3,000 to $7,500 on average for overlay-based tub and shower liner installations over existing fixtures, per one independent cost source ^[33]. Another independent review reports $4,000 to $14,000 depending on tub/shower size and accessories, applying only to existing wet-area liner installations ^[38]. A third source cites $2,000 to $18,000 for standard liner remodels based on size and options ^[36]. No public fixed price was verified for a new bathroom addition; Bath Fitter says pricing varies by project and selected products and provides a customized estimate after consultation ^[25]. Financing options, including possible promotional terms, are advertised, but actual APR, duration, eligibility, and lender terms are location- and offer-dependent ^[25]. Potential costs for excavation or slab cutting, new drainage, sewage ejector equipment, venting, permits, inspections, framing, electrical, HVAC, flooring, drywall, and third-party trades are not publicly itemized for this use case ^[24]. Pricing confidence across sources is low to moderate.

Where platforms disagreed. Customer satisfaction metrics vary dramatically. ConsumerAffairs reports 4.3 stars from over 5,000 reviews with 76% five-star ratings ^[51], while PissedConsumer reports 2.7 stars from 482 reviews ^[29]. Whether all Bath Fitter franchises offer full bathroom remodeling capability is unresolved: Bath Fitter of Pittsburgh's franchise website claims full remodeling including gutting to studs and drywall ^[1], but this is not confirmed as standard across all franchises, and BBB rating and accreditation varies by location ^[58]. One source says Bath Fitter installation includes plumbing connections and permits ^[25], while other public descriptions emphasize over-existing-fixture remodeling ^[21]. The exact extent of new plumbing scope for a new bath addition is unclear. Warranty coverage clarity is also disputed: the lifetime warranty covers liner damage and broken items, but customers and the company disagree on whether faulty installation is covered versus parts defects only ^[48].

2. EcoFlow LLC

Questions explored

• Is EcoFlow LLC worth it for a basement bathroom addition that needs a sewage ejector pump and new drainage?
• What should a buyer verify before hiring EcoFlow LLC for a new bathroom addition in Connecticut or Westchester County?
• Does EcoFlow LLC handle waterproofing, tiling, and finishes, or only plumbing rough-in for a new bathroom?

Verdict. EcoFlow LLC is the strongest qualifying option for the plumbing-intensive portion of a new basement bathroom, especially where a sewage ejector, new drainage, and venting are required. It is not yet a clearly strong fit for a complete turnkey bathroom addition because public information does not establish detailed waterproofing and tiling capability, full-room construction scope, written warranty terms, pricing, or timeline performance beyond the company's stated typical duration ^[7]. Buyers should treat it as a potentially strong plumbing subcontractor or a possible lead contractor, not an assumed turnkey remodeler.

Why it ranked here. EcoFlow LLC was named by 2 of 7 platforms (Grok and Kimi) at an average listed position of 3.0, with a best position of 1 on Grok. It ranks second because it was named by fewer platforms than Bath Fitter, even though its average listed position is better. Its fit ratings across platforms ranged from strong (Gemini, Grok) to good (ChatGPT, Claude, Perplexity) to uncertain (DeepSeek, Kimi).

Best suited for. Basement bathrooms below the main sewer line; projects needing concrete breaking, new drain and supply lines, venting, and a sewage ejector system; homeowners who will separately manage framing, drywall, waterproofing, tile, glass, or other finishing trades; homeowners in Fairfield County or Litchfield County, Connecticut, or Westchester County, New York.

Main strengths for the use case. The advertised service directly matches new basement-bathroom plumbing rather than only repair work ^[7]. Public scope explicitly includes rough-in plumbing, new drainage, venting, sewage ejector equipment, fixture connections, permit coordination, and final inspection ^[7]. The company offers a plumbing-only option for homeowners using separate finishing trades ^[7]. It states that a typical basement bathroom installation takes one to two weeks, with rough-in plumbing usually taking two to three days ^[7]. It advertises free on-site estimates, clear detailed quotes, and a response within 24 hours ^[3]. It publishes Connecticut and Westchester County license identifiers and states that it is fully insured ^[2]. It works with brands including Kohler, American Standard, Moen, and Zoeller pumps ^[2]. A small independent marketplace review record includes positive comments about a basement bathroom project, communication, cleanliness, and cost clarity ^[55].

Main limitations. Public evidence is stronger for plumbing infrastructure than for a complete bathroom addition ^[7]. Waterproofing, tile installation, finish coordination, electrical work, and egress-related construction are not clearly included ^[7]. No verified prices, contract terms, schedule guarantee, or detailed workmanship warranty were found ^[7]. Review volume is small, and detailed independent evidence about below-grade bathroom durability is limited ^[55]. Service availability appears geographically limited to specified Connecticut and Westchester County areas ^[2]. One platform could not independently verify the company or its website through accessible sources and rated the fit uncertain ^[2]. The company claims "18+ years experience" and "founded 2014," which do not align (2026 minus 2014 equals 12 years) ^[2].

Pricing or cost summary. No published project price was found. EcoFlow states that cost varies by bathroom size, fixture quality, half-bath versus full-bath scope, concrete breaking, and ejector-pump requirements, and that it provides an estimate after evaluating the basement ^[7]. The company advertises free on-site estimates and no-obligation consultations ^[3]. Potentially separate or additional costs include electrical work, framing, drywall, waterproofing, tile, glass, cabinetry, HVAC, finish materials, restoration of concrete, engineering, or unusual discharge and vent runs; exact inclusions are unclear ^[7]. No public contract template, payment schedule, cancellation policy, change-order procedure, or dispute terms were found ^[7]. Pricing confidence is low across all platforms.

Where platforms disagreed. Fit ratings diverged sharply. Google and Grok rated EcoFlow LLC a strong fit ^[7]; ChatGPT, Claude, and Perplexity rated it good ^[7]; DeepSeek and Kimi rated it uncertain, with Kimi unable to verify the company or its website through accessible sources ^[2]. Whether the company handles attic bathrooms is disputed: ChatGPT notes that attic venting, structural, supply-routing, and ceiling-height requirements differ and asks whether EcoFlow handles them ^[7], while Claude states the company focuses on basement and below-grade plumbing and is probably not best for attic installations ^[7]. Whether waterproofing and tiling are included is unresolved: the company acknowledges that proper waterproofing and drainage are essential for any below-grade shower installation ^[7], but the website does not specify waterproofing methods, materials, tiling installation expertise, or membrane systems employed ^[7]. Warranty existence is confirmed but specific terms are not publicly available ^[44]. The company advertises complete installation while another page explicitly allows the homeowner to handle framing, drywall, and finishing; the exact turnkey boundary must be defined in the proposal ^[7]. Entity-name confusion is a documented risk: multiple companies use the "EcoFlow" name, including a portable power station brand unrelated to plumbing ^[2].

What this study reveals

Questions explored

• Why did only two bathroom remodeling companies qualify for this new bathroom addition ranking out of 46 named entities?
• What does the gap between platform mentions and fit ratings reveal about AI recommendations for new bathroom additions?

The most revealing finding is the gap between discovery and suitability. Bath Fitter was named by more platforms than any other entity, yet every platform that assessed fit rated it weak for this exact use case. EcoFlow LLC was named by fewer platforms but received the strongest fit ratings (strong on Gemini and Grok). This means the consensus ranking measures how often platforms surface a brand, not how well that brand matches a ground-up bathroom addition.

The second finding is fragmentation. Of 46 unique entities named across seven platforms, only two were named by at least two platforms. That is a 4.3% qualification rate. For a complex, geographically variable, trade-heavy project like a new bathroom addition, platforms appear to draw on local or regional contractors that other platforms never mention, which suppresses cross-platform agreement.

The third finding is that the market splits into two distinct service models that platforms treat as one category. One model is surface replacement over existing plumbing (Bath Fitter's documented scope). The other is plumbing infrastructure for below-grade space (EcoFlow LLC's advertised scope). Buyers searching for "bathroom remodeling companies" for a new addition may receive recommendations from either model, and the two are not interchangeable.

The fourth finding is that no qualifying entity was documented as a full turnkey addition contractor. Bath Fitter's public scope does not establish excavation, framing, electrical, HVAC, permits, or all addition plumbing ^[24]. EcoFlow LLC's public materials do not clearly establish waterproofing, tiling, electrical, HVAC, cabinetry, or glass work ^[7]. Buyers wanting one contract for everything may need to look beyond this qualifying set.

Where the AI Platforms Agreed

Questions explored

• Which bathroom remodeling company do most AI platforms agree is a weak fit for a new bathroom addition?

Platforms agreed on several points about Bath Fitter. All seven platforms that assessed fit rated it weak for a new bathroom addition. They agreed that its core model is acrylic overlay or replacement over existing fixtures rather than new construction plumbing ^[15]. They agreed it does not document new drainage runs, sewage ejector installation, or new vent-stack work for basement or attic additions ^[24]. They agreed its one-day installation claim applies to the retrofit product, not to a full addition schedule ^[15]. They agreed its lifetime warranty is product-focused and does not clearly extend to third-party plumbing, pumps, or addition-related labor ^[28].

Platforms also agreed on EcoFlow LLC's core plumbing scope. Multiple platforms confirmed that its advertised basement bathroom service includes rough-in plumbing, ejector pump systems, drainage, and fixture installation ^[7]. They agreed it handles permit coordination ^[7]. They agreed its service area is limited to Fairfield County and Litchfield County, Connecticut, and Westchester County, New York ^[2]. They agreed no fixed public pricing is available ^[7].

Where the AI Platforms Disagreed

Questions explored

• Why do AI platforms disagree about whether EcoFlow LLC is a strong or uncertain fit for a basement bathroom addition?
• Which bathroom remodeling company has conflicting customer review scores across platforms, and what does that mean for buyers?

The largest disagreement concerns EcoFlow LLC's overall fit. Google and Grok rated it strong ^[7]. Openai, Claude, and Perplexity rated it good ^[7]. Deepseek and Kimi rated it uncertain, with Kimi reporting that the company and its website could not be independently verified through accessible sources ^[2]. This is a material conflict: a buyer relying on one platform could receive a very different recommendation than a buyer relying on another.

A second disagreement concerns attic bathrooms. Openai treats attic suitability as an open question requiring verification ^[7], while Claude states the company focuses on basement and below-grade plumbing and is probably not best for attic installations ^[7]. The evidence does not resolve which is correct.

A third disagreement concerns Bath Fitter's customer satisfaction. ConsumerAffairs reports 4.3 stars from over 5,000 reviews ^[51], while PissedConsumer reports 2.7 stars from 482 reviews ^[29]. Warranty disputes and installation errors are documented on negative platforms but less prominent on mainstream platforms ^[29].

A fourth disagreement concerns Bath Fitter's franchise scope. One franchise website claims full top-to-bottom remodeling ^[1], while the company's national public materials describe retrofit and replacement solutions ^[24]. Whether any given location accepts new basement or attic bathroom additions is unresolved.

A fifth disagreement concerns whether Bath Fitter's installation includes plumbing connections and permits. One source says it does ^[25], while other public descriptions emphasize over-existing-fixture remodeling ^[21].

How to compare your options

Questions explored

• What should a buyer check before choosing a bathroom remodeling company for a new bathroom addition?
• Which contractor should a homeowner hire first for a basement bathroom addition that needs both plumbing rough-in and finished tile?

Start by separating the project into two scopes: plumbing infrastructure and finished construction. If the project requires breaking concrete, new drain and supply lines, a sewage ejector system, and vent stacks, the evidence points to a plumbing-first contractor with documented below-grade experience, such as EcoFlow LLC within its service area ^[7]. If the room and rough plumbing already exist and the buyer mainly needs a tub, shower, wall system, and selected fixtures, Bath Fitter's documented model applies ^[15].

If the buyer wants one contract covering framing, drywall, waterproofing, tile, electrical, cabinetry, glass, and finishes, neither qualifying entity's public materials clearly establish that scope ^[24]. In that case, buyers should look for a design-build or general contractor with documented basement or attic bathroom case studies, and may use a qualifying entity as a plumbing subcontractor.

Verify credentials before signing. Ask whether the exact local location will contract for a bathroom where none currently exists ^[24]. Ask who is responsible for design, permits, inspections, excavation or slab cutting, framing, electrical, HVAC, drywall, flooring, and finish work ^[24]. Ask whether the company will install and warranty new sanitary drainage, plumbing vents, and a sewage ejector, grinder pump, or upflush system if required ^[24]. Ask for recent references for comparable basement or attic bathroom additions rather than retrofit remodels ^[24].

For EcoFlow LLC specifically, confirm the pump brand, model, horsepower, basin size, alarm, check valve, and backup-power provisions proposed ^[7]. Confirm who performs and warrants waterproofing, shower-pan construction, tile, grout, glass, drywall, framing, electrical, and finish restoration ^[7]. Confirm the exact written warranty periods and exclusions for plumbing, pump equipment, leaks, waterproofing, fixtures, labor, and consequential damage ^[7]. Confirm whether the company's published licenses and insurance are currently active for the specific property location and work scope ^[7].

For Bath Fitter specifically, confirm whether the local franchise pulls plumbing and building permits for a new bathroom addition or only retrofits existing bathrooms ^[32]. Confirm whether the lifetime warranty covers installation errors or only material defects ^[29]. Confirm whether the company can work without an existing tub or shower to install over ^[38].

Methodology

This index was produced from a single standardized prompt sent once to each of seven included platforms: ChatGPT, Claude, DeepSeek, Grok, Perplexity, Kimi, and Gemini. The prompt asked each platform to identify bathroom remodeling contractors or installers suited to a homeowner creating a bathroom where none existed, requiring new supply, waste, and often a sewage ejector or venting run, in the United States.

The ranking rule is deterministic: entities are ordered by platform mentions, then average listed position, then best listed rank. The final ranking table is the sole authority for rank, platform mentions, platform share, average rank, and best rank. Fit evidence comes from the entity evidence bundles. No value embedded in an entity evidence bundle overrides the final ranking table.

Eligibility required an entity to be named by at least two platforms during ranking discovery. Platform mentions count only ranking-discovery mentions; they do not count the number of platforms that later completed a fit assessment. All seven included platforms evaluated fit for the two qualifying entities, but only four platforms named Bath Fitter during discovery and only two named EcoFlow LLC.

Citations are platform-reported evidence, not independently verified facts. The supplied URLs were collected from platform responses and were not independently validated by the writer stage. Company-owned sources are distinguished from independent sources in the consolidated source list. Official-page excerpts are retrieved material, not verified facts; absence of an excerpt does not prove absence of a capability.

Research limitations

Several limitations apply. First, only two entities met the two-platform eligibility rule out of 46 unique entities named, so the ranking covers a small fraction of the market. Second, the study used one standardized prompt sent once to each platform; AI answers can vary by date, wording, location, account state, model, interface, browsing configuration, and the sources retrieved. Third, platform recommendations are market intelligence, not independent customer reviews or proof of quality. Fourth, platform-reported research dates differ from the authoritative run date: DeepSeek reported 2026-01-15 while the other six platforms reported 2026-10-02; platform-reported dates are provenance metadata and do not independently prove freshness. Fifth, DeepSeek ran without search enabled, so its claims require explicit verification before being described as current facts. Sixth, the supplied URLs were collected from platform responses and were not independently validated. Seventh, citations are platform-reported evidence, not independently verified facts. Eighth, entity-name confusion is a documented risk for EcoFlow LLC, which shares a name with an unrelated portable power station brand. Ninth, the deterministic identity audit collapsed company-name variants onto one canonical brand before minimum-mentions qualification, and official-site retrieval failed for one or more mentions; no failed fetch was used as a verified domain key. Tenth, missing research is not evidence of disagreement; where a platform did not address a factor, this report treats it as unverified rather than contradicted.

The consensus assessment

Bath Fitter ranks first by platform mentions (4 of 7, 57.1%) but is a weak fit for a true new bathroom addition on every platform that assessed it. EcoFlow LLC ranks second by mentions (2 of 7, 28.6%) but is the only qualifying entity whose public scope explicitly covers new drainage runs, sewage ejector systems, venting, and permit coordination for below-grade bathrooms, and it received the strongest fit ratings. For a homeowner creating a bathroom where none existed, the practical reading is: use EcoFlow LLC or a comparable plumbing-first contractor for the below-grade plumbing scope within its service area, and treat Bath Fitter as a possible finishing-surface option only after rough plumbing is complete. Neither qualifying entity is documented as a full turnkey addition contractor, so buyers who want one contract for everything should verify scope in writing or look beyond this qualifying set.

Frequently Asked Questions

Is Bath Fitter good for a new bathroom addition? No, based on the reviewed evidence. All seven platforms that assessed fit rated Bath Fitter weak for this use case. Its documented core offering is a retrofit over or in place of an existing tub or shower, not ground-up construction with new drainage, ejector, or venting work ^[15].

Can Bath Fitter install a sewage ejector pump? No official source reviewed confirms that Bath Fitter supplies, designs, installs, or warranties sewage ejector, grinder-pump, or upflush toilet systems for new basement bathrooms ^[24].

Does EcoFlow LLC serve the whole United States? No. EcoFlow LLC states that it serves Fairfield County and Litchfield County, Connecticut, and Westchester County, New York ^[2].

Does EcoFlow LLC handle waterproofing and tiling? The reviewed public sources do not document its waterproofing method, tile installation warranty, or independent quality results ^[7]. The company acknowledges that proper waterproofing and drainage are essential for below-grade shower installation, but the method is not specified.

How much does a new bathroom addition cost? Bathroom addition costs range from $5,000 to $75,000, with the total determined by bathroom type and fixtures selected, per one independent source ^[40]. Neither qualifying entity publishes a fixed price for a new addition.

Why did only two companies qualify? Eligibility required an entity to be named by at least two of the seven platforms during ranking discovery. Of 46 unique entities named, only Bath Fitter and EcoFlow LLC met that threshold.

Are platform recommendations the same as customer reviews? No. Platform recommendations are market intelligence from AI systems, not independent customer reviews or proof of quality. Customer review data cited in this report comes from separate review platforms and is noted as such.

Which company should a buyer choose for a basement bathroom below the sewer line? EcoFlow LLC is the better-ranked option for that specific situation because its advertised service explicitly includes ejector pump with basin, new drain lines, supply lines, vent stack installation, permit coordination, and final inspection ^[7], within its stated service area.
