What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and hardware — is demolished and replaced with a professionally installed shower unit. The scale of the project is shaped by your existing bathroom footprint, your design preferences, and whether you want to expand the shower's usable area beyond the original tub's location.
On a mechanical level, the work involves capping the existing tub drain and supply lines, removing the tub unit and any tile, drywall, or backer board that was tied to it, then constructing the new shower floor with a code-compliant slope toward the shower drain. New moisture barrier is installed before any finish material goes on. Plumbing is modified to accommodate the new showerhead location and any extra spray features you choose.
The finished product is a fully waterproofed shower that functions properly for many years. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a fundamental upgrade to your bathroom's infrastructure and finish.
Top Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs occupy between 13 and 16 square feet. Converting to a walk-in shower frees up that area to usable, accessible bathroom space.
- Better Mobility Access — A tub to shower conversion can incorporate a zero-entry design, support handles, and a fold-down bench to accommodate homeowners with limited mobility.
- More Efficient Daily Bathing — The majority of adults shower far more often than they bathe. A tub to shower conversion aligns your bathroom with how you spend your time.
- Higher Resale Value — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion communicates updated finishes to future owners.
- Easier Cleaning — Shower floors and walls are often simpler to clean and maintain than a full-length bathtub with hard-to-reach corners.
- Custom Design Options — From large-format porcelain tiles to heavy-duty shower curtain systems, a tub to shower conversion creates room for far more design options than a prefab tub kit.
- Lower Utility Bills — Filling a bathtub uses roughly 30 to 50 gallons of water per session. A low-flow showerhead installed during a tub to shower conversion can lower usage to significantly less water per session.
- Long-Term Durability — When Brother & Brother Builders installs a tub to shower conversion, the structural components are built to last well beyond 20 years.
The Tub to Shower Conversion Process Step by Step
- In-Home Evaluation and Scope Review — A member of our team comes to your bathroom to assess your existing fixtures and framing. We review your goals, design preferences, and budget so the scope of work matches exactly what you want.
- Removal of the Existing Tub and Surround — The existing bathtub, tub surround, and any damaged or outdated backer board are taken out. Supply and drain lines tied to the old tub are properly shut off to make room for the revised drain placement.
- Building the Shower's Foundation — This is widely considered the most important stage of a tub to shower conversion. New waterproof backer material is screwed to the wall studs, and a full waterproofing membrane is installed across the shower floor and lower walls. The drain area is pitched properly to ensure drainage.
- Installing New Shower Plumbing — Licensed plumbers or our experienced crew position the new shower valve, drain body, and supply lines according to your fixture selections. Whether you chose a single overhead rain head, a handheld wand, or a multi-function valve system, everything is installed at this phase.
- Applying Your Chosen Finish Materials — Tile setters apply your selected finish material using appropriate mortar, grout, and setting materials. Every tile edge is grouted and reviewed before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your preference, we mount your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Each component is set into the tile or framing to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once the full shower is complete, we do a careful quality review. All caulk joints at corners and the floor-to-wall transition are finished with flexible waterproof sealant. We walk you through the finished shower and verify everything meets your expectations.
