What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and plumbing fixtures — is removed and replaced with a purpose-built shower unit. The scale of the project depends on your existing bathroom footprint, your style choices, and whether you need to expand the shower's square footage beyond the original tub's space.
On a mechanical level, the project involves capping the existing tub drain and supply lines, removing the tub itself and any surrounding wall material that was tied to it, then constructing the new shower pan with a correct slope toward the drain. New waterproof liner is installed before any tile, stone, or prefab panel goes up. Plumbing is rerouted to serve the new showerhead position and any extra spray features you choose.
The finished product is a code-compliant shower that drains correctly for decades. A tub to shower conversion done correctly is not just a visual change — it is a thorough upgrade to your bathroom's plumbing, waterproofing, and layout.
Key Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs consume between 13 and 16 square feet. Converting to a custom shower stall restores that square footage to usable, open bathroom space.
- Improved Accessibility — A tub to shower conversion can feature a barrier-free floor transition, safety rails, and a fold-down bench to assist aging adults, people with disabilities, or anyone recovering from surgery.
- More Efficient Daily Bathing — Most people shower far more often than they bathe. A tub to shower conversion matches your space with how you really live.
- Stronger Home Appraisals — Updated bathrooms always show up among the top home improvements for resale. A tub to shower conversion signals modern, move-in-ready conditions to future owners.
- Lower Maintenance Demands — Shower surrounds and bases are generally easier to keep spotless than a deep-soaking bathtub with grout lines on all four sides.
- Personalized Finish Choices — From subway tile surrounds to heavy-duty shower curtain systems, a tub to shower conversion opens up many more design possibilities than a standard tub surround.
- Reduced Water Use — Filling a bathtub requires roughly 30 to 50 gallons of water per session. A low-flow showerhead installed during a tub to shower conversion can cut that to under 20 gallons per shower.
- Long-Term Durability — When Brother & Brother Builders completes a tub to shower conversion, the structural components are designed for durability through years of daily use.

- In-Home Evaluation and Scope Review — A project consultant meets with you on-site to measure your existing space and infrastructure. We discuss your goals, design preferences, and budget so the proposal reflects exactly what you have in mind.
- Demolition and Removal — The existing fixtures and surrounding structure are demolished and cleared. Existing water supply tied to the old tub are properly shut off to prepare for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is arguably the most important stage of a tub to shower conversion. New cement board or tile backer is screwed to the wall studs, and a industry-standard moisture barrier is applied across every area that will contact water. The floor base is graded toward the drain to avoid standing water.
- Installing New Shower Plumbing — Skilled tradespeople on our crew set the new shower valve, drain body, and supply lines according to your chosen layout. Whether you chose a standard showerhead or an upgraded fixture package, everything is positioned at this stage.
- Applying Your Chosen Finish Materials — Skilled installers set your selected finish material using appropriate mortar, grout, and setting materials. Every tile edge is grouted and reviewed before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your design choice, we install your shower door or curtain hardware. Every mounting bracket is secured correctly to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once all surfaces is finished and installed, we conduct a thorough final inspection. Each transition joint at the base and wall corners are finished with mold-resistant silicone caulk. We walk you through the final result and verify everything is exactly what you wanted.
