What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its enclosure and drain assembly — is removed and replaced with a purpose-built shower unit. The scope of the project varies based on your existing bathroom plumbing configuration, your style choices, and whether you want to expand the shower's footprint beyond the original tub's space.
On a mechanical level, the work involves rerouting the existing tub drain and supply lines, taking out the tub unit and any surrounding wall material that was tied to it, then constructing the new shower floor with a code-compliant slope toward the shower drain. New waterproof liner is installed before any tile, stone, or prefab panel goes in. Plumbing is rerouted to serve the new showerhead location and any additional fixtures you add.
The finished product is a structurally sound shower that performs reliably for decades. A tub to shower conversion done right is not just a visual change — it is a complete improvement to your bathroom's structure and usability.
Key Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs consume between 13 and 16 square feet. Converting to a walk-in shower restores that room to usable, open bathroom space.
- Improved Accessibility — A tub to shower conversion can include a barrier-free floor transition, support handles, and a shower bench to support aging adults, people with disabilities, or anyone recovering from surgery.
- Quicker Showers — A large portion of homeowners shower far more often than they bathe. A tub to shower conversion matches your space with how you really live.
- Better Return on Investment — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion communicates updated finishes to real estate agents.
- Simpler Upkeep — Shower pans, walls, and glass enclosures are typically faster to clean and maintain 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 creates room for far more design directions than a prefab tub kit.
- Reduced Water Use — Running a full bath consumes roughly 30 to 50 gallons of water per use. A water-efficient shower fixture installed during a tub to shower conversion can reduce consumption to significantly less water per session.
- Long-Term Durability — When Brother & Brother Builders completes a tub to shower conversion, the waterproofing, substrate, and finish materials are constructed to hold up for decades.
The Tub to Shower Conversion Procedure Step by Step

- Removal of the Existing Tub and Surround — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Existing water supply tied to the old tub are professionally handled to prepare for the updated fixture configuration.
- Building the Shower's Foundation — This is widely considered the most critical stage of a tub to shower conversion. New cement board or tile backer is screwed to the structural framing, and a industry-standard moisture barrier is applied across the shower floor and lower walls. The floor base is sloped correctly to avoid standing water.
- Plumbing Rough-In and Fixture Placement — Our plumbing team position the new rough-in plumbing according to your design plan. Whether you went with a basic or premium shower setup, everything is roughed in at this phase.
- Tile, Stone, or Panel Installation — Tile setters apply your preferred wall and floor covering using the correct adhesive and grout system. Every seam is finished and reviewed before glass or curtain hardware is installed.

- Completion Walk-Through and Finishing Touches — Once the full shower is finished and installed, we conduct a thorough quality review. Each transition joint at the perimeter are sealed with mold-resistant silicone caulk. We show you the finished shower and make sure everything meets your expectations.
Who Is a Strong Candidate for a Tub to Shower Conversion?
