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 drain assembly — is taken out and replaced with a purpose-built shower unit. The complexity of the project is shaped by your existing bathroom layout, your style choices, and whether you need to expand the shower's square footage beyond the original tub's location.
On a structural level, the process involves disconnecting the existing tub drain and supply lines, taking out the tub shell and any tile, drywall, or backer board that was tied to it, then building out the new shower base with a correct slope toward the shower drain. New moisture barrier is applied before any surface covering goes on. Plumbing is adjusted to serve the new showerhead position and any additional fixtures you choose.
The result is a fully waterproofed shower that functions properly for the long term. A tub to shower conversion done by experienced hands is not just a visual change — it is a complete 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 curbless shower frees up that room to usable, navigable bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can incorporate a zero-entry design, safety rails, and a shower bench to assist homeowners with limited mobility.
- More Efficient Daily Bathing — Most people shower much more frequently than they bathe. A tub to shower conversion redesigns your layout with how you spend your time.
- Stronger Home Appraisals — Updated bathrooms consistently rank 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 often simpler to clean and maintain than a standard bathtub with grout lines on all four sides.
- Tailored Aesthetic Selections — 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 standard tub surround.
- Lower Utility Bills — Running a full bath consumes roughly 30 to 50 gallons of water per session. A modern shower valve installed during a tub to shower conversion can reduce consumption to as little as 15 gallons.

The Tub to Shower Conversion Project Step by Step
- Project Assessment and Design — A remodeling specialist comes to your bathroom to assess your existing tub, plumbing, and bathroom layout. We review your goals, design preferences, and budget so the scope of work reflects exactly what you want.
- Tub Extraction and Teardown — The existing fixtures and surrounding structure are demolished and cleared. Supply and drain lines tied to the old tub are disconnected, capped, or rerouted to make room for the revised drain placement.
- Building the Shower's Foundation — This is often the most technically demanding stage of a tub to shower conversion. New cement board or tile backer is fastened to the structural framing, and a full waterproofing membrane is installed across the shower floor and lower walls. The drain area is graded toward the drain to ensure drainage.
- Installing New Shower Plumbing — Skilled tradespeople on our crew set the new rough-in plumbing according to your fixture selections. Whether you went with a basic or premium shower setup, everything is installed at this stage.
- Finishing the Shower Walls and Floor — Tile setters apply your preferred wall and floor covering using professional-grade installation materials. Every seam is finished and inspected before glass or curtain hardware is installed.
- Hanging Doors, Glass, or Hardware — Depending on your selected style, we hang 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 all surfaces is complete, we conduct a thorough walk-through. Each transition joint at the perimeter are sealed with flexible waterproof sealant. We show you the finished shower and make sure everything meets your expectations.
