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 framing and hardware — is taken out and replaced with a custom-fitted shower unit. The scale of the project is shaped by your existing bathroom footprint, your finish selections, and whether you plan to expand the shower's usable area beyond the original tub's position.
On a mechanical level, the work involves capping the existing tub drain and supply lines, removing the tub unit and any tile, drywall, or backer board that was tied to it, then constructing the new shower pan with a code-compliant slope toward the drain. New waterproofing membrane is laid down before any surface covering goes in. Plumbing is modified to serve the new showerhead height and any body sprays, handheld wands, or rain heads you add.
The outcome is a code-compliant shower that performs reliably for many years. 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 structure and usability.

The Tub to Shower Conversion Process Step by Step
- Initial Consultation and Planning — A member of our team comes to your bathroom to measure your existing tub, plumbing, and bathroom layout. We go over your wishlist and timeline so the project plan matches exactly what you want.
- Demolition and Removal — The existing fixtures and surrounding structure are demolished and cleared. Supply and drain lines tied to the old tub are professionally handled to set the stage for the updated fixture configuration.
- Structural Prep and Moisture Barrier Installation — This is arguably the most critical stage of a tub to shower conversion. New waterproof backer material is attached to the structural framing, and a continuous waterproof layer is rolled or troweled on across all wet surfaces. The drain area is graded toward the drain to ensure drainage.
- Setting Valves, Drains, and Supply Lines — Our plumbing team position the new plumbing fixtures according to your design plan. Whether you went with a standard showerhead or an upgraded fixture package, everything is roughed in at this point.
- Finishing the Shower Walls and Floor — Skilled installers apply your chosen wall tile, floor tile, or solid surface panels using appropriate mortar, grout, and setting materials. Every tile edge is finished and checked before glass or curtain hardware is installed.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we mount your chosen enclosure system. Every mounting bracket is set into the tile or framing to provide a solid, long-lasting result.
- Quality Check and Project Sign-Off — Once the full shower is complete, we perform a thorough walk-through. Each transition joint at the base and wall corners are finished with professional-grade caulk. We review with you the completed project and make sure everything is exactly what you wanted.
