What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and hardware — is removed and replaced with a professionally installed shower unit. The complexity of the project is shaped by your existing bathroom layout, your finish selections, and whether you want to expand the shower's square footage beyond the original tub's space.
On a mechanical level, the work involves rerouting the existing tub drain and supply lines, lifting the tub shell and any tile, drywall, or backer board that was tied to it, then framing the new shower floor with a correct slope toward the center drain. New waterproofing membrane is installed before any surface covering goes up. Plumbing is modified to fit the new showerhead location and any additional fixtures you select.
The result is a structurally sound shower that drains correctly for many years. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a fundamental transformation to your bathroom's plumbing, waterproofing, and layout.

- Framing, Waterproofing, and Substrate Work — This is widely considered the most critical stage of a tub to shower conversion. New cement board or tile backer is attached to the framing, and a continuous waterproof layer is installed across every area that will contact water. The drain area is pitched properly to ensure drainage.

- Tile, Stone, or Panel Installation — Tile setters install your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every tile edge is sealed and reviewed before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your design choice, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. All hardware is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Quality Check and Project Sign-Off — Once all surfaces is finished and installed, we do a thorough quality review. All caulk joints at the perimeter are caulked with mold-resistant silicone caulk. We walk you through the completed project and verify everything is exactly what you wanted.
