What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its framing and plumbing fixtures website — is demolished and replaced with a purpose-built shower unit. The complexity of the project is shaped by your existing bathroom plumbing configuration, your style choices, and whether you plan to expand the shower's square footage beyond the original tub's location.
On a technical level, the work involves disconnecting the existing tub drain and supply lines, taking out the tub unit and any surrounding wall material that was tied to it, then building out the new shower base with a correct slope toward the center drain. New waterproof liner is installed before any surface covering goes on. Plumbing is rerouted to serve the new showerhead position and any extra spray features you add.
The result is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done right is not just a surface-level change — it is a thorough transformation to your bathroom's infrastructure and finish.
Top Benefits of a Tub to Shower Conversion

- Faster Morning Routines — A large portion of homeowners shower much more frequently than they bathe. A tub to shower conversion matches your space with how you spend your time.
- Higher Resale Value — Updated bathrooms always show up among the most valued renovations for resale. A tub to shower conversion signals modern, move-in-ready conditions to real estate agents.
- Easier Cleaning — Shower surrounds and bases are generally easier to keep spotless than a deep-soaking bathtub with grout lines on all four sides.
- Custom Design Options — From subway tile surrounds to heavy-duty shower curtain systems, a tub to shower conversion opens up far more design possibilities than a prefab tub kit.
- Reduced Water Use — Running a full bath consumes roughly 30 to 50 gallons of water per use. A low-flow showerhead installed during a tub to shower conversion can cut that to under 20 gallons per shower.

The Tub to Shower Conversion Procedure Step by Step
- In-Home Evaluation and Scope Review — A project consultant visits your home to measure your existing fixtures and framing. We review your goals, design preferences, and budget so the proposal reflects exactly what you want.
- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are carefully removed. Existing water supply tied to the old tub are professionally handled to prepare for the new shower plumbing layout.
- Building the Shower's Foundation — This is often the most critical stage of a tub to shower conversion. New cement board or tile backer is screwed to the wall studs, and a continuous waterproof layer is installed across all wet surfaces. The shower pan is graded toward the drain to ensure drainage.
- Plumbing Rough-In and Fixture Placement — Our plumbing team position the new shower valve, drain body, and supply lines according to your design plan. Whether you selected a basic or premium shower setup, everything is roughed in at this stage.
- Finishing the Shower Walls and Floor — Skilled installers apply your preferred wall and floor covering using appropriate mortar, grout, and setting materials. Every seam is sealed and reviewed before glass or curtain hardware is installed.
- Installing the Shower Enclosure — Depending on your preference, we install your shower door or curtain hardware. 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 conduct a room-by-room final inspection. Each transition joint at the base and wall corners are sealed with professional-grade caulk. We show you the final result and verify everything is exactly what you wanted.
