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 demolished and replaced with a professionally installed shower unit. The scope of the project depends on your existing bathroom footprint, your style choices, and whether you want to expand the shower's footprint beyond the original tub's location.
On a technical level, the process involves rerouting the existing tub drain and supply lines, lifting the tub shell and any old tile surround that was tied to it, then building out the new shower base with a proper slope toward the drain. New waterproof liner is installed before any tile, stone, or prefab panel goes up. Plumbing is adjusted to accommodate the new showerhead position and any extra spray features you select.
The outcome is a structurally sound shower that functions properly for many years. A tub to shower conversion done correctly is not just a surface-level change — it is a complete transformation to your bathroom's plumbing, waterproofing, and layout.
Top Benefits of a Tub to Shower Conversion

- Lower Maintenance Demands — Shower floors and walls are generally easier to scrub and wipe down than a standard bathtub with a surrounding tile enclosure.

The Tub to Shower Conversion Project Step by Step
- Project Assessment and Design — A remodeling specialist visits your home to assess your existing tub, plumbing, and bathroom layout. We review your must-haves and finish choices so the proposal matches exactly what you need.
- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are taken out. Supply and drain lines tied to the old tub are disconnected, capped, or rerouted to set the stage for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is widely considered the most critical stage of a tub to shower conversion. New cement board or tile backer is attached to the wall studs, and a full waterproofing membrane is applied across the shower floor and lower walls. The shower pan is pitched properly to ensure drainage.
- Installing New Shower Plumbing — Our plumbing team set the new shower valve, drain body, and supply lines according to your design plan. Whether you went with a single overhead rain head, a handheld wand, or a multi-function valve system, everything is positioned at this phase.
- Finishing the Shower Walls and Floor — 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 grouted and reviewed before glass or curtain hardware is installed.
- Hanging Doors, Glass, or Hardware — Depending on your design choice, we hang your shower door or curtain hardware. All hardware is secured correctly to provide a solid, long-lasting result.
- Completion Walk-Through and Finishing Touches — Once the full shower is complete, we do a room-by-room final inspection. All caulk joints at the base and wall corners are finished with professional-grade caulk. We review with you the finished shower and confirm everything is exactly what you wanted.
