What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its surround and drain assembly — is removed and replaced with a professionally installed shower unit. The scope of the project is shaped by your existing bathroom footprint, your style choices, and whether you need to expand the shower's footprint beyond the original tub's space.
On a structural level, the work involves rerouting the existing tub drain and supply lines, taking out the tub itself and any tile, drywall, or backer board that was tied to it, then building out the new shower pan with a correct slope toward the shower drain. New waterproofing membrane is installed before any finish material goes up. Plumbing is modified to fit the new showerhead height and any extra spray features you add.
The result is a structurally sound shower that drains correctly for decades. A tub to shower conversion done correctly is not just a cosmetic change — it is a complete transformation to your bathroom's plumbing, waterproofing, and layout.
Top Benefits of a Tub to Shower Conversion

The Tub to Shower Conversion Procedure Step by Step
- In-Home Evaluation and Scope Review — A member of our team meets with you on-site to evaluate your existing space and infrastructure. We go over your wishlist and timeline so the proposal reflects exactly what you have in mind.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared.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 disconnected, capped, or rerouted to set the stage for the revised drain placement.
- Framing, Waterproofing, and Substrate Work — This is arguably 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 continuous waterproof layer is installed across every area that will contact water. The shower pan is pitched properly to ensure drainage.
- Installing New Shower Plumbing — Skilled tradespeople on our crew position the new shower valve, drain body, and supply lines according to your fixture selections. Whether you selected a basic or premium shower setup, everything is installed at this point.
- Applying Your Chosen Finish Materials — Our finish crew apply your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every grout joint is finished and checked before moving to the next phase.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we hang your chosen enclosure system. All hardware is set into the tile or framing to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once the full shower is tiled, grouted, and enclosed, 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 show you the finished shower and verify everything is exactly what you wanted.
Who Is a Good Candidate for a Tub to Shower Conversion?
Anyone who finds the existing tub more of an obstacle than an asset are usually perfect for a tub to shower conversion. This is especially relevant for homeowners who struggle with high tub walls — a curbless or low-threshold shower is among the most meaningful accessibility changes you can invest in for your bathroom.

A tub to shower conversion also works well for people dealing with a cramped layout where the tub monopolizes the floor plan. Eliminating the bathtub and installing a more compact shower footprint can dramatically improve the sense of space.

Our team at our firm will give you a straight answer if a tub to shower conversion is not the right fit for your particular situation.
