What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its enclosure and drain assembly — is taken out and replaced with a purpose-built shower unit. The scale of the project is shaped by your existing bathroom plumbing configuration, your style choices, and whether you plan to expand the shower's usable area beyond the original tub's location.
On a mechanical level, the project involves rerouting the existing tub drain and supply lines, removing the tub shell and any tile, drywall, or backer board that was tied to it, then constructing the new shower floor with a correct slope toward the shower drain. New moisture barrier is laid down before any tile, stone, or prefab panel goes on. Plumbing is modified to accommodate the new showerhead location and any additional fixtures you add.
The outcome is a structurally sound shower that drains correctly for many years. A tub to shower conversion done by experienced hands is not just a visual change — it is a thorough improvement to your bathroom's structure and usability.
Major Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs take up between 13 and 16 square feet. Converting to a walk-in shower returns that area to usable, navigable bathroom space.
- Improved Accessibility — A tub to shower conversion can feature a zero-entry design, safety rails, and a fold-down bench to support homeowners with limited mobility.
- Quicker Showers — The majority of adults shower much more frequently than they bathe. A tub to shower conversion aligns your bathroom with how you spend your time.
- Better Return on Investment — Updated bathrooms reliably appear among the top home improvements for resale. A tub to shower conversion signals modern, move-in-ready conditions to prospective buyers.
- Simpler Upkeep — Shower floors and walls are generally easier to scrub and wipe down than a full-length bathtub with hard-to-reach corners.
- Personalized Finish Choices — From subway tile surrounds to heavy-duty shower curtain systems, a tub to shower conversion unlocks significantly broader design directions than a prefab tub kit.
- Reduced Water Use — Filling a bathtub uses roughly 30 to 50 gallons of water per bath. A low-flow showerhead installed during a tub to shower conversion can cut that to significantly less water per session.
- Long-Term Durability — When Brother & Brother Builders builds a tub to shower conversion, the structural components are designed for durability for decades.
The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A member of our team visits your home to assess your existing space and infrastructure. We discuss your goals, design preferences, and budget so the proposal aligns with exactly what you have in mind.
- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are carefully removed. Any plumbing connections tied to the old tub are professionally handled to set the stage for the revised drain placement.
- Building the Shower's Foundation — This is arguably the most critical stage of a tub to shower conversion. New cement board or tile backer is attached to the wall studs, and a industry-standard moisture barrier is applied across the shower floor and lower walls. The shower pan is pitched properly to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Our plumbing team set the new shower valve, drain body, and supply lines according to your chosen layout. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is roughed in at this point.
- Applying Your Chosen Finish Materials — Skilled installers apply your chosen wall tile, floor tile, or solid surface panels using appropriate mortar, grout, and setting materials. Every tile edge is grouted and checked before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your preference, we hang your shower door or curtain hardware. All hardware is secured correctly to prevent loosening over time.
- Final Inspection, Grouting, and Caulking — Once all surfaces is complete, we do a thorough final inspection. All caulk joints at the base and wall corners are finished with professional-grade caulk. We walk you through the finished shower and confirm everything is exactly what you wanted.
