The Tub to Shower Conversion Process Step by Step
- Project Assessment and Design — A member of our team visits your home to measure your existing space and infrastructure. We go over your must-haves and finish choices so the scope of work reflects exactly what you want.
- Removal of the Existing Tub and Surround — The existing bathtub, tub surround, and any damaged or outdated backer board are taken out. Supply and drain lines tied to the old tub are disconnected, capped, or rerouted to make room for the new shower plumbing layout.
- Framing, Waterproofing, and Substrate Work — This is arguably the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is fastened to the framing, and a industry-standard moisture barrier is rolled or troweled on across the shower floor and lower walls. The shower pan is pitched properly to avoid standing water.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew set the new rough-in plumbing according to your design plan. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is installed at this point.
- Tile, Stone, or Panel Installation — Skilled installers apply your selected finish material using professional-grade installation materials. Every tile edge is sealed and reviewed before moving to the next phase.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your preference, we hang your shower door or curtain hardware. All hardware is secured correctly to ensure years of smooth, wobble-free operation.
- Quality Check and Project Sign-Off — Once everything is complete, we do a thorough final inspection. Every seam at corners and the floor-to-wall transition are sealed with professional-grade caulk. We review with you the finished shower and confirm everything is exactly what you wanted.

Our experts at our firm will always be honest if a tub to shower conversion is not the best call for your particular situation.
