- Project Assessment and Design — A project consultant meets with you on-site to evaluate your existing space and infrastructure. We go over your must-haves and finish choices so the project plan aligns with exactly what you want.
- Demolition and Removal — The existing tub unit and wall material are demolished and cleared. Existing water supply tied to the old tub are professionally handled to prepare for the revised drain placement.
- Building the Shower's Foundation — This is often the most important stage of a tub to shower conversion. New cement board or tile backer is screwed to the framing, and a continuous waterproof layer is installed across all wet surfaces. The drain area is pitched properly to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew set the new shower valve, drain body, and supply lines according to your fixture selections.

We review with you the finished shower and verify everything looks and functions as planned.
