The Tub to Shower Conversion Process Step by Step

1. Initial Consultation and Planning — A project consultant visits your home to assess your existing space and infrastructure. We review your wishlist and timeline so the scope of work matches exactly what you have in mind.
2. Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are taken out. Any plumbing connections tied to the old tub are disconnected, capped, or rerouted to set the stage for the updated fixture configuration.
3. Framing, Waterproofing, and Substrate Work — 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 rolled or troweled on across all wet surfaces. The shower pan is sloped correctly to ensure drainage.
4. Plumbing Rough-In and Fixture Placement — Licensed plumbers or our experienced crew set the new plumbing fixtures according to your design plan. Whether you went with a standard showerhead or an upgraded fixture package, everything is installed at this stage.
5. Tile, Stone, or Panel Installation — Skilled installers set your chosen wall tile, floor tile, or solid surface panels using appropriate mortar, grout, and setting materials. Every tile edge is grouted and inspected before glass or curtain hardware is installed.
6. Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we mount your shower door or curtain hardware. Each component is anchored properly to prevent loosening over time.
7. Final Inspection, Grouting, and Caulking — Once everything is finished and installed, we perform a room-by-room walk-through. Every seam at corners and the floor-to-wall transition are caulked with professional-grade caulk. We walk you through the finished shower and verify everything looks and functions as planned.
