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 purpose-built shower unit. The complexity of the project is shaped by your existing bathroom layout, your style choices, and whether you want to expand the shower's footprint beyond the original tub's space.
On a technical level, the work involves disconnecting the existing tub drain and supply lines, lifting the tub itself and any old tile surround that was tied to it, then constructing the new shower base with a proper slope toward the shower drain. New moisture barrier is applied before any here tile, stone, or prefab panel goes on. Plumbing is rerouted to fit the new showerhead height and any additional fixtures you select.
The outcome is a fully waterproofed shower that drains correctly for decades. A tub to shower conversion done correctly is not just a visual change — it is a complete upgrade to your bathroom's infrastructure and finish.

- Removal of the Existing Tub and Surround — The existing bathtub, tub surround, and any damaged or outdated backer board are taken out. Existing water supply tied to the old tub are professionally handled to prepare for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is often the most important stage of a tub to shower conversion. New waterproof backer material is screwed to the structural framing, and a continuous waterproof layer is rolled or troweled on across the shower floor and lower walls. The drain area is graded toward the drain to prevent pooling.

- Applying Your Chosen Finish Materials — Skilled installers set your preferred wall and floor covering using appropriate mortar, grout, and setting materials. Every seam is grouted and checked before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your design choice, we hang your chosen enclosure system. Each component is set into the tile or framing to ensure years of smooth, wobble-free operation.

Every seam at the perimeter are finished with mold-resistant silicone caulk. We review with you the finished shower and make sure everything is exactly what you wanted.
