What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its surround and plumbing fixtures — is removed and replaced with a professionally installed shower unit. The complexity of the project varies based on your existing bathroom footprint, your style choices, and whether you want to expand the shower's usable area beyond the original tub's position.
On a technical level, the process involves rerouting the existing tub drain and supply lines, lifting the tub shell and any surrounding wall material that was tied to it, then constructing the new shower base with a proper slope toward the drain. New waterproof liner is applied before any tile, stone, or prefab panel goes on. Plumbing is adjusted to fit the new showerhead height and any additional fixtures you select.
The outcome is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a thorough transformation to your bathroom's infrastructure and finish.

- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are taken out. Existing water supply tied to the old tub are properly shut off to prepare for the updated fixture configuration.
- Structural Prep and Moisture Barrier Installation — This is widely considered the most technically demanding stage of a tub to shower conversion. New waterproof backer material is attached to the structural framing, and a full waterproofing membrane is installed across the shower floor and lower walls. The shower pan is sloped correctly to ensure drainage.

- Finishing the Shower Walls and Floor — Tile setters set your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every grout joint is finished and checked before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your design choice, we install your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Every mounting bracket is anchored properly to prevent loosening over time.
- Completion Walk-Through and Finishing Touches — Once everything is complete, we do a thorough final inspection. Every seam at corners and the floor-to-wall transition are finished with professional-grade caulk. We review with you the final result and make sure everything is exactly what you wanted.
