What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its enclosure and drain assembly — is taken out and replaced with a professionally installed shower unit. The scope of the project depends on your existing bathroom plumbing configuration, your design preferences, and whether you need to expand the shower's footprint beyond the original tub's space.
On a structural level, the process involves capping the existing tub drain and supply lines, lifting the tub unit and any old tile surround that was tied to it, then framing the new shower base with a correct slope toward the drain. New waterproofing membrane is installed before any tile, stone, or prefab panel goes in. Plumbing is rerouted to accommodate the new showerhead location and any body sprays, handheld wands, or rain heads you choose.
The result is a code-compliant shower that drains correctly for the long term. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a complete upgrade to your bathroom's infrastructure and finish.

- Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are carefully removed. Any plumbing connections tied to the old tub are professionally handled to make room for the revised drain placement.
- Building the Shower's Foundation — This is often the most important stage of a tub to shower conversion. New waterproof backer material is fastened to the wall studs, and a full waterproofing membrane is installed across all wet surfaces. The shower pan is graded toward the drain to avoid standing water.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew position the new plumbing fixtures according to your design plan. Whether you chose a standard showerhead or an upgraded fixture package, everything is positioned at this point.
- Applying Your Chosen Finish Materials — Skilled installers install your preferred wall and floor covering using the correct adhesive and grout system. Every tile edge is grouted and checked before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your design choice, we mount your shower door or curtain hardware. Every mounting bracket is set into the tile or framing to prevent loosening over time.
- Completion Walk-Through and Finishing Touches — Once the full shower is tiled, grouted, and enclosed, we do a room-by-room final inspection. All caulk joints at the perimeter are sealed with mold-resistant silicone caulk. We review with you the final result and verify everything is exactly what you wanted.
