The Tub to Shower Conversion Procedure Step by Step

- Removal of the Existing Tub and Surround — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared.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 professionally handled to set the stage for the updated fixture configuration.
- Building the Shower's Foundation — This is widely considered the most important stage of a tub to shower conversion. New waterproof backer material is attached to the framing, and a continuous waterproof layer is applied across all wet surfaces. The floor base is graded toward the drain to avoid standing water.
- Plumbing Rough-In and Fixture Placement — Licensed plumbers or our experienced crew install the new rough-in plumbing according to your fixture selections. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is roughed in at this point.
- Tile, Stone, or Panel Installation — Our finish crew set your preferred wall and floor covering using appropriate mortar, grout, and setting materials. Every grout joint is sealed and inspected before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we hang your shower door or curtain hardware. Every mounting bracket is anchored properly to ensure years of smooth, wobble-free operation.

Each transition joint at corners and the floor-to-wall transition are caulked with mold-resistant silicone caulk. We show you the final result and verify everything looks and functions as planned.
