What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and drain assembly — is removed and replaced with a purpose-built shower unit. The complexity of the project varies based on your existing bathroom footprint, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's location.
On a mechanical level, the project involves rerouting the existing tub drain and supply lines, taking out the tub itself and any surrounding wall material that was tied to it, then framing the new shower floor with a code-compliant slope toward the center drain. New waterproof liner is laid down before any finish material goes more info on. Plumbing is modified to accommodate the new showerhead position and any extra spray features you choose.
The outcome is a code-compliant shower that functions properly for many years. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a fundamental transformation to your bathroom's plumbing, waterproofing, and layout.

The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A project consultant comes to your bathroom to measure your existing fixtures and framing. We discuss your goals, design preferences, and budget so the project plan matches exactly what you want.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Any plumbing connections tied to the old tub are properly shut off to set the stage for the new shower plumbing layout.
- Structural Prep and Moisture Barrier Installation — This is often the most technically demanding stage of a tub to shower conversion. New cement board or tile backer is attached to the structural framing, and a full waterproofing membrane is applied across every area that will contact water. The drain area 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 chose a standard showerhead or an upgraded fixture package, everything is installed at this phase.
- Applying Your Chosen Finish Materials — Tile setters install your selected finish material using appropriate mortar, grout, and setting materials. Every grout joint is finished and inspected before glass or curtain hardware is installed.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we hang your chosen enclosure system. Every mounting bracket is set into the tile or framing to prevent loosening over time.
- Final Inspection, Grouting, and Caulking — Once everything is finished and installed, we do a thorough walk-through. 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 looks and functions as planned.
