The Tub to Shower Conversion Process Step by Step
- Initial Consultation and Planning — A project consultant visits your home to assess your existing fixtures and framing. We discuss your must-haves and finish choices so the scope of work reflects exactly what you have in mind.
- Demolition and Removal — The existing tub unit and wall material are taken out. Supply and drain lines tied to the old tub are disconnected, capped, or rerouted to make room for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is arguably the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the structural framing, and a continuous waterproof layer is applied across every area that will contact water. The drain area is pitched properly to avoid standing water.
- Setting Valves, Drains, and Supply Lines — Skilled tradespeople on our crew install the new plumbing fixtures according to your chosen layout. Whether you chose a standard showerhead or an upgraded fixture package, everything is roughed in at this stage.
- Tile, Stone, or Panel Installation — Tile setters set your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every tile edge is grouted and inspected before glass or curtain hardware is installed.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we install your chosen enclosure system. Each component is secured correctly to ensure years of smooth, wobble-free operation.
- Completion Walk-Through and Finishing Touches — Once all surfaces is complete, we perform a room-by-room walk-through. Every seam at the base and wall corners are sealed with flexible waterproof sealant. We review with you the final result and confirm everything looks and functions as planned.
