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 framing and hardware — is taken out and replaced with a professionally installed shower unit. The complexity of the project is shaped by your existing bathroom plumbing configuration, your design preferences, and whether you need to expand the shower's usable area beyond the original tub's position.
On a mechanical level, the process involves capping the existing tub drain and supply lines, lifting the tub shell and any surrounding wall material that was tied to it, then framing the new shower base with a proper slope toward the center drain. New waterproofing membrane is laid down before any tile, stone, or prefab panel goes in. Plumbing is modified to fit the new showerhead location and any body sprays, handheld wands, or rain heads you add.
The outcome is a fully waterproofed shower that performs reliably for many years. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a complete transformation to your bathroom's structure and usability.
Top 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.
- Aging-in-Place Functionality — A tub to shower conversion can include a low-threshold or curbless entry, support handles, and a built-in seat to accommodate homeowners with limited mobility.

- Stronger Home Appraisals — Updated bathrooms consistently rank 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 floors and walls are often simpler to keep spotless than a deep-soaking bathtub with grout lines on all four sides.
- Personalized Finish Choices — From subway tile surrounds to frameless glass doors, a tub to shower conversion unlocks many more design possibilities than a standard tub surround.
- Reduced Water Use — Soaking in a tub uses roughly 30 to 50 gallons of water per use. A water-efficient shower fixture installed during a tub to shower conversion can lower usage to significantly less water per session.

- Structural Prep and Moisture Barrier Installation — This is arguably the most critical 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 all wet surfaces. The floor base is graded toward the drain to avoid standing water.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew install the new shower valve, drain body, and supply lines according to your chosen layout. Whether you chose a basic or premium shower setup, everything is roughed in at this point.

- Installing the Shower Enclosure — Depending on your selected style, we hang your chosen enclosure system. All hardware is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Quality Check and Project Sign-Off — Once the full shower is complete, we perform a room-by-room walk-through. Every seam at corners and the floor-to-wall transition are caulked with professional-grade caulk. We walk you through the completed project and verify everything is exactly what you wanted.
