What Exactly 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 hardware — is removed and replaced with a custom-fitted shower unit. The scope of the project varies based on your existing bathroom plumbing configuration, your design preferences, and whether you want to expand the shower's usable area beyond the original tub's space.
On a structural level, the work involves capping the existing tub drain and supply lines, taking out the tub itself and any tile, drywall, or backer board that was tied to it, then constructing the new shower floor with a correct slope toward the drain. New moisture barrier is installed before any surface covering goes on. Plumbing is rerouted to serve the new showerhead height and any additional fixtures you select.
The result is a structurally sound shower that performs reliably for decades. A tub to shower conversion done correctly is not just a surface-level change — it is a fundamental transformation to your bathroom's infrastructure and finish.
Key Benefits of a Tub to Shower Conversion

- Tub Extraction and Teardown — The existing fixtures and surrounding structure are carefully removed. Existing water supply tied to the old tub are professionally handled to set the stage for the new shower plumbing layout.
- 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 applied across the shower floor and lower walls. The floor base is graded toward the drain to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Skilled tradespeople on our crew position the new plumbing fixtures according to your fixture selections. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is installed at this stage.
- Applying Your Chosen Finish Materials — Skilled installers install your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every grout joint is finished and inspected before glass or curtain hardware is installed.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your selected style, we install your shower door or curtain hardware. Every mounting bracket is set into the tile or framing to prevent loosening over time.
- Quality Check and Project Sign-Off — Once everything is tiled, grouted, and enclosed, we conduct a room-by-room quality review. Every seam at the base and wall corners are finished with professional-grade caulk. We walk you through the final result and make sure everything looks and functions as planned.
