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 hardware — is taken out and replaced with a custom-fitted shower unit. The scope of the project depends on your existing bathroom plumbing configuration, your style choices, and whether you want to expand the shower's square footage beyond the original tub's position.

On a mechanical 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 framing the new shower pan with a correct slope toward the center drain. New moisture barrier is laid down before any surface covering goes in. Plumbing is modified to accommodate the new showerhead position and any additional fixtures you choose.

The outcome is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done right is not just a cosmetic change — it is a fundamental improvement to your bathroom's structure and usability.

The Tub to Shower Conversion Project Step by Step

1. Project Assessment and Design — A member of our team visits your home to evaluate your existing space and infrastructure. We review your must-haves and finish choices so the proposal matches exactly what you have in mind.
2. Removal of the Existing Tub and Surround — The existing tub unit and wall material are demolished and cleared. Supply and drain lines tied to the old tub are disconnected, capped, or rerouted to make room for the new shower plumbing layout.
3. Building the Shower's Foundation — This is arguably the most important stage of a tub to shower conversion. New waterproof backer material is screwed to the structural framing, and a continuous waterproof layer is rolled or troweled on across all wet surfaces. The floor base is graded toward the drain to avoid standing water.
4. Installing New Shower Plumbing — Our plumbing team position the new shower valve, drain body, and supply lines according to your chosen layout. Whether you went with a standard showerhead or an upgraded fixture package, everything is roughed in at this phase.
5. Tile, Stone, or Panel Installation — Our finish crew apply your chosen wall tile, floor tile, or solid surface panels using appropriate mortar, grout, and setting materials. Every tile edge is sealed and checked before the enclosure goes in.
6. Hanging Doors, Glass, or Hardware — Depending on your design choice, we mount your chosen enclosure system. All hardware is set into the tile or framing to prevent loosening over time.
7. Quality Check and Project Sign-Off — Once everything is complete, we perform a careful quality review. Each transition joint at corners and the floor-to-wall transition are finished with professional-grade caulk. We show you the completed project and verify everything is exactly what you wanted.
