The scale of the project varies based on your existing bathroom layout, your finish selections, and whether you plan to expand the shower's footprint beyond the original tub's position.
On a technical level, the project involves capping the existing tub drain and supply lines, taking out the tub itself and any tile, drywall, or backer board that was tied to it, then framing the new shower pan with a proper slope toward the center drain. New waterproof liner is laid down before any surface covering goes in. Plumbing is modified to check here accommodate the new showerhead location and any extra spray features you choose.

The Tub to Shower Conversion Project Step by Step

- Building the Shower's Foundation — This is often the most important stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the structural framing, and a full waterproofing membrane is rolled or troweled on across every area that will contact water. The floor base is graded toward the drain to prevent pooling.
- Installing New Shower Plumbing — Skilled tradespeople on our crew install the new shower valve, drain body, and supply lines according to your chosen layout. Whether you selected a standard showerhead or an upgraded fixture package, everything is roughed in at this point.

- Final Inspection, Grouting, and Caulking — Once the full shower is complete, we do a room-by-room final inspection. Every seam at the base and wall corners are caulked with professional-grade caulk. We review with you the final result and confirm everything looks and functions as planned.
