What Actually 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 taken out and replaced with a custom-fitted shower unit. The complexity 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 position.

On a technical level, the process involves capping the existing tub drain and supply lines, lifting the tub unit and any surrounding wall material that was tied to it, then framing the new shower pan with a code-compliant slope toward the shower drain. New waterproofing membrane is laid down before any surface covering goes on. Plumbing is rerouted to serve the new showerhead height and any body sprays, handheld wands, or rain heads you select.

The result is a code-compliant shower that functions properly for decades. A tub to shower conversion done right is not just a visual change — it is a complete upgrade to your bathroom's structure and usability.

Major Benefits of a Tub to Shower Conversion

• Personalized Finish Choices — From subway tile surrounds to frameless glass doors, a tub to shower conversion unlocks many more design options than a one-piece tub unit.

The Tub to Shower Conversion Process Step by Step

2. Removal of the Existing Tub and Surround — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Any plumbing connections tied to the old tub are disconnected, capped, or rerouted to set the stage for the updated fixture configuration.

The drain area is sloped correctly to avoid standing water.

5. Finishing the Shower Walls and Floor — Our finish crew set your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every tile edge is sealed and checked before glass or curtain hardware is installed.
6. Installing the Shower Enclosure — Depending on your design choice, we mount your shower door or curtain hardware. All hardware is secured correctly to provide a solid, long-lasting result.
7. Completion Walk-Through and Finishing Touches — Once the full shower is tiled, grouted, and enclosed, we do a thorough walk-through. Each transition joint at corners and the floor-to-wall transition are finished with mold-resistant silicone caulk. We show you the finished shower and make sure everything looks and functions as planned.
