3. Structural Prep and Moisture Barrier Installation — This is widely considered the most critical stage of a tub to shower conversion. New cement board or tile backer is fastened to the framing, and a continuous waterproof layer is rolled or troweled on across the shower floor and lower walls. The drain area is graded toward the drain to avoid standing water.
4. Setting Valves, Drains, and Supply Lines — Our plumbing team set the new rough-in plumbing according to your fixture selections. Whether you chose a single overhead rain head, a handheld wand, or a multi-function valve system, everything is positioned at this phase.
5. Applying Your Chosen Finish Materials — Tile setters set your selected finish material using appropriate mortar, grout, and setting materials. Every seam is finished and reviewed before glass or curtain hardware is installed.
6. Installing the Shower Enclosure — Depending on your selected style, we mount your chosen enclosure system. All hardware is set into the tile or framing to prevent loosening over time.
7. Final Inspection, Grouting, and Caulking — Once everything is tiled, grouted, and enclosed, we do a careful quality review. Every seam at the base and wall corners are finished with mold-resistant silicone caulk. We walk you through the finished shower and verify everything meets your expectations.
