What does “replace the tub with a shower” mean for your project?
There are two different project outcomes to separate:
- Keep bathing and shower use: Replace the existing tub with a tub-shower combination, or replace it with a tub and retain or add a shower arrangement as part of the planned scope. This keeps a bathing well. MAAX lists combined tub-shower products, including one-piece and sectional examples; those product categories do not establish fit or feasibility in a particular room. MAAX: Tub Showers
- Remove the bathing well: Replace the tub area with a shower-only design. The intended base, walls, and enclosure need to be identified as a proposed assembly. MAAX presents shower bases as a separate product family with different layout examples; that distinction does not say which design fits your room or what work conversion requires. MAAX: Shower Bases
Before requesting a quote, say which outcome you want. If you are undecided, compare both as separate scopes. Consider whether anyone in the household uses or expects to use a tub; who will enter and use the bathing area; what entry, reach, and cleaning preferences matter; and whether the room must serve changing needs over time. These are personal decision criteria, not a finding that either configuration meets an accessibility standard or a particular person's needs. If accessibility or mobility is a concern, describe the need and have the actual space and proposed product reviewed by an appropriately qualified person.
What should be documented before comparing products or proposals?
Record the facts you already know, and mark the rest unknown. Useful scope inputs include:
- Whether the project retains a tub and shower use, or removes the tub for a shower-only result.
- The existing fixture and any known model or installation information from records; do not infer the model from appearance.
- The intended product model and installation form, once selected, plus its published finished dimensions and specifications.
- The finished opening and surrounding room constraints that a professional must verify, including entry space, door or enclosure movement, and access for delivery and removal.
- The wall and floor conditions visible without opening or disturbing anything, and any known history of prior repairs or water damage.
- The desired storage, controls, spray arrangement, and finish boundaries, described as preferences for a proposal to resolve—not as proof that an item will fit or work with existing connections.
Do not treat a product-family page or a rough homeowner measurement as a fit assessment. MAAX lists different bathtub installation forms and directs readers to exact model specifications; its shower-base range is separately organized by layout. The model, room, and proposed assembly still need to be matched to the actual space. MAAX: Bathtubs · MAAX: Shower Bases
Which product and site requirements still need confirmation?
A category name is not an installation plan. For the exact selected tub or shower, ask the manufacturer and responsible installer to identify the applicable model documentation and confirm in writing what the product requires for the specific project. Resolve the proposed base or tub, wall system, enclosure, support and substrate, waterproofing approach, drain arrangement, and valve and connection scope as applicable. These are questions for the exact product and project, not universal specifications or instructions for doing the work.
Do not assume existing drain, valve, plumbing, walls, or floor can be used unchanged. Use documentation for the exact selected model; a different model's guide does not establish its requirements. MAAX's guide index lists separate documents for different assembly types, but the linked PDF contents have not been reviewed here and no installation detail is established by the index.

What depends on the home, product, and jurisdiction?
Existing plumbing and electrical conditions, concealed wall or floor conditions, and jurisdiction are unknown. Ask the responsible contractor and relevant local authority which plumbing, electrical, accessibility, permit, and inspection requirements apply to this exact scope and location; do not assume a conversion is exempt or that a product makes the room accessible. If opening the area reveals an unexpected condition, pause the affected work until its implications and any proposed change are explained and authorized. No universal permit outcome or accessibility result is established here.
What should a written proposal spell out?
Compare proposals only after each describes the same end result and identifies unresolved assumptions. The U.S. Federal Trade Commission advises consumers to get written estimates describing the work and materials and to read the agreement; it also notes that state contract requirements vary. That is general consumer advice, not a bathroom-specific contract rule. FTC: How To Avoid a Home Improvement Scam
For a useful comparison, ask each proposal to state:
- Whether the tub stays, is replaced with another tub-shower arrangement, or is removed for shower-only use.
- The exact product manufacturer, model, finish, included components, and proposed assembly—or what remains undecided.
- What demolition, removal, disposal, and protection of adjacent areas are included, and what is excluded.
- Which wall, floor, plumbing, electrical, enclosure, trim, and finish areas are included, and where the work stops.
- Which product instructions and project-specific requirements the installer will follow, who confirms them, and what review remains pending.
- How concealed conditions will be documented, priced or otherwise handled, and who must authorize a change before changed work proceeds.
- What checks or tests are included before completion, what warranty terms apply to which products or work, and who is responsible for each item.
- The proposed schedule and dependencies, including product selection, required approvals, and decisions that could change the scope.
Do not compare a tub replacement that retains bathing with a shower-only conversion as though they were the same job. If the exact assembly, finish boundaries, applicable requirements, concealed-condition process, testing, warranty, schedule, or responsibility remain unclear, request a written answer before selecting the proposal or authorizing work. The proposal and project review must establish details specific to the actual property, product, and jurisdiction.
