What Exactly Is a Tub to Shower Conversion?

A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its enclosure and hardware — is taken out and replaced with a custom-fitted shower unit. The complexity of the project varies based on your existing bathroom plumbing configuration, your style choices, and whether you plan to expand the shower's usable area beyond the original tub's position.

New moisture barrier is laid down before any finish material goes on. Plumbing is modified to accommodate the new showerhead location and any body sprays, handheld wands, or rain heads you choose.

The Tub to Shower Conversion Procedure Step by Step

1. In-Home Evaluation and Scope Review — A member of our team meets with you on-site to measure your existing fixtures and framing. We review your must-haves and finish choices so the proposal aligns with exactly what you want.
2. Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared.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 updated fixture configuration.
3. Structural Prep and Moisture Barrier Installation — This is widely considered the most important stage of a tub to shower conversion. New cement board or tile backer is fastened to the wall studs, and a industry-standard moisture barrier is rolled or troweled on across all wet surfaces. The shower pan is pitched properly to prevent pooling.
4. Installing New Shower Plumbing — Skilled tradespeople on our crew set the new rough-in plumbing according to your design plan. Whether you selected a standard showerhead or an upgraded fixture package, everything is positioned at this phase.
5. 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 tile edge is finished and checked before moving to the next phase.
6. Hanging Doors, Glass, or Hardware — Depending on your design choice, we install your chosen enclosure system. Each component is anchored properly to prevent loosening over time.
7. Quality Check and Project Sign-Off — Once the full shower is tiled, grouted, and enclosed, we conduct a room-by-room quality review. All caulk joints at the perimeter are sealed with flexible waterproof sealant. We review with you the final result and confirm everything meets your expectations.
