What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its framing and drain assembly — is taken out and replaced with a professionally installed shower unit. The scale of the project depends on your existing bathroom plumbing configuration, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's position.
On a structural level, the project involves capping the existing tub drain and supply lines, removing the tub unit and any old tile surround that was tied to it, then building out the new shower pan with a code-compliant slope toward the center drain. New waterproof liner is applied before any surface covering goes in. Plumbing is modified to accommodate the new showerhead position and any additional fixtures you select.
The result is a code-compliant shower that performs reliably for decades. A tub to shower conversion done correctly is not just a visual change — it is a fundamental transformation to your bathroom's infrastructure and finish.
Key Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs take up between 13 and 16 square feet. Converting to a walk-in shower restores that room to usable, navigable bathroom space.
- Improved Accessibility — A tub to shower conversion can feature a barrier-free floor transition, grab bars, and a shower bench to accommodate aging adults, people with disabilities, or anyone recovering from surgery.
- More Efficient Daily Bathing — A large portion of homeowners shower much more frequently than they bathe. A tub to shower conversion redesigns your layout with how you really live.
- Higher Resale Value — Updated bathrooms reliably appear among the highest-ROI upgrades for resale. A tub to shower conversion tells buyers the home has been maintained to real estate agents.
- Simpler Upkeep — Shower pans, walls, and glass enclosures are generally easier to scrub and wipe down than a full-length bathtub with a surrounding tile enclosure.
- Personalized Finish Choices — From large-format porcelain tiles to heavy-duty shower curtain systems, a tub to shower conversion unlocks far more design possibilities than a one-piece tub unit.
- Reduced Water Use — Soaking in a tub requires roughly 30 to 50 gallons of water per session. A modern shower valve installed during a tub to shower conversion can lower usage to significantly less water per session.
- Long-Term Durability — When Brother & Brother Builders builds a tub to shower conversion, the waterproofing, substrate, and finish materials are built to last through years of daily use.
The Tub to Shower Conversion Project Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist visits your home to evaluate your existing fixtures and framing. We discuss your must-haves and finish choices so the proposal reflects exactly what you have in mind.
- Tub Extraction and Teardown — The existing fixtures and surrounding structure are carefully removed. Existing water supply tied to the old tub are professionally handled to make room for the new shower plumbing layout.
- Framing, Waterproofing, and Substrate Work — This is often the most critical stage of a tub to shower conversion. New waterproof backer material is attached to the framing, and a full waterproofing membrane is applied across the shower floor and lower walls. The shower pan is graded toward the drain to prevent pooling.
- Plumbing Rough-In and Fixture Placement — Our plumbing team set the new rough-in plumbing according to your fixture selections. Whether you went with a single overhead rain head, a handheld wand, or a multi-function valve system, everything is roughed in at this point.
- Finishing the Shower Walls and Floor — Our finish crew install your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every seam is grouted and reviewed before moving to the next phase.
- Installing the Shower Enclosure — Depending on your design choice, we install your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Every mounting bracket is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Completion Walk-Through and Finishing Touches — Once all surfaces is finished and installed, we perform a thorough quality review. All caulk joints at the perimeter are sealed with flexible waterproof sealant. We walk you through the final result and make sure everything is exactly what you wanted.
Who Is a Good Candidate for a Tub to Shower Conversion?

Our team at our firm will always be honest if a tub to shower conversion is not the right fit for your home.
