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 removed and replaced with a custom-fitted shower unit. The scale of the project varies based on your existing bathroom layout, your finish selections, and whether you need to expand the shower's usable area beyond the original tub's position.
On a mechanical level, the process involves disconnecting the existing tub drain and supply lines, removing the tub unit and any old tile surround that was tied to it, then building out the new shower base with a code-compliant slope toward the shower drain. New waterproofing membrane is laid down before any tile, stone, or prefab panel goes in. Plumbing is rerouted to accommodate the new showerhead location and any extra spray features you add.
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 visual change — it is a fundamental upgrade to your bathroom's infrastructure and finish.

- Better Return on Investment — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion signals modern, move-in-ready conditions to prospective buyers.
- Lower Maintenance Demands — Shower floors and walls are generally easier to clean and maintain than a standard bathtub with hard-to-reach corners.
- Personalized Finish Choices — From subway tile surrounds to semi-frameless enclosures, a tub to shower conversion unlocks far more design possibilities than a one-piece tub unit.

New waterproof backer material is attached to the wall studs, and a full waterproofing membrane is applied across all wet surfaces. The floor base is pitched properly to ensure drainage.
- Plumbing Rough-In and Fixture Placement — Our plumbing team install the new plumbing fixtures according to your chosen layout. Whether you selected a standard showerhead or an upgraded fixture package, everything is positioned at this stage.
- Applying Your Chosen Finish Materials — Tile setters set your chosen wall tile, floor tile, or solid surface panels using appropriate mortar, grout, and setting materials. Every seam is finished and inspected before moving to the next phase.
- Installing the Shower Enclosure — Depending on your design choice, we mount your chosen enclosure system. Every mounting bracket is set into the tile or framing to provide a solid, long-lasting result.
- Completion Walk-Through and Finishing Touches — Once everything is tiled, grouted, and enclosed, we conduct a careful final inspection. Each transition joint at corners and the floor-to-wall transition are finished with flexible waterproof sealant. We show you the completed project and confirm everything is exactly what you wanted.
