What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and plumbing fixtures — is demolished and replaced with a purpose-built shower unit. The scale of the project depends on your existing bathroom footprint, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's space.
On a technical level, the process involves capping the existing tub drain and supply lines, lifting the tub shell and any tile, drywall, or backer board that was tied to it, then building out the new shower pan with a correct slope toward the drain. New moisture barrier is applied before any tile, stone, or prefab panel goes on. Plumbing is adjusted to serve the new showerhead position and any extra spray features you add.
The outcome is a code-compliant shower that drains correctly for the long term. A tub to shower conversion done correctly is not just a surface-level change — it is a thorough upgrade to your bathroom's plumbing, waterproofing, and layout.

The floor base is sloped correctly to ensure drainage.

- Tile, Stone, or Panel Installation — Tile setters set your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every tile edge is sealed and inspected before glass or curtain hardware is installed.
- Hanging Doors, Glass, or Hardware — Depending on your selected style, we mount your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Each component is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Completion Walk-Through and Finishing Touches — Once all surfaces is tiled, grouted, and enclosed, we conduct a thorough final inspection. Every seam at the base and wall corners are finished with mold-resistant silicone caulk. We review with you the final result and make sure everything meets your expectations.
