What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and plumbing fixtures — is removed and replaced with a custom-fitted shower unit. The complexity of the project varies based on your existing bathroom plumbing configuration, your finish selections, and whether you plan to expand the shower's footprint beyond the original tub's space.
On a structural level, the process involves disconnecting the existing tub drain and supply lines, removing the tub itself and any old tile surround that was tied to it, then framing the new shower base with a proper slope toward the center drain. New waterproofing membrane is laid down before any tile, stone, or prefab panel goes up. Plumbing is modified to fit the new showerhead location and any additional fixtures you choose.
The outcome is a structurally sound shower that drains correctly for the long term. A tub to shower conversion done right is not just a cosmetic change — it is a fundamental upgrade to your bathroom's infrastructure and finish.
Top Benefits of a Tub to Shower Conversion

The Tub to Shower Conversion Process Step by Step
- Initial Consultation and Planning — A remodeling specialist meets with you on-site to measure your existing tub, plumbing, and bathroom layout. We review your must-haves and finish choices so the proposal reflects exactly what you have in mind.
- Tub Extraction and Teardown — The existing fixtures and surrounding structure are taken out. Any plumbing connections tied to the old tub are professionally handled to set the stage for the revised drain placement.
- 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 screwed to the framing, and a industry-standard moisture barrier is installed across all wet surfaces. The floor base is graded toward the drain to ensure drainage.
- Plumbing Rough-In and Fixture Placement — Our plumbing team install the new rough-in plumbing according to your chosen layout. Whether you selected a basic or premium shower setup, everything is installed at this point.
- Finishing the Shower Walls and Floor — Our finish crew apply your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every seam is sealed and inspected before glass or curtain hardware is installed.
- Installing the Shower Enclosure — Depending on your design choice, we hang your shower door or curtain hardware. All hardware is secured correctly to ensure years of smooth, wobble-free operation.
- Completion Walk-Through and Finishing Touches — Once the full shower is tiled, grouted, and enclosed, we conduct a room-by-room walk-through. All caulk joints at the base and wall corners are caulked with flexible waterproof sealant. We review with you the final result and make sure everything is exactly what you wanted.
