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 framing and drain assembly — is taken out and replaced with a purpose-built shower unit. The complexity 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 location.
On a structural level, the work involves rerouting the existing tub drain and supply lines, lifting the tub unit and any old tile surround that was tied to it, then constructing the new shower base with a correct slope toward the center drain. New waterproofing membrane is installed before any finish material goes on. Plumbing is adjusted to serve the new showerhead position and any additional fixtures you choose.
The outcome is a fully waterproofed shower that functions properly for many years. A tub to shower conversion done by experienced hands is not just a visual change — it is a complete transformation to your bathroom's infrastructure and finish.

The Tub to Shower Conversion Project Step by Step
- Initial Consultation and Planning — A remodeling specialist comes to your bathroom to evaluate your existing space and infrastructure. We discuss your must-haves and finish choices so the proposal matches exactly what you need.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared.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 disconnected, capped, or rerouted to make room for the updated fixture configuration.
- Building the Shower's Foundation — This is widely considered the most important stage of a tub to shower conversion. New cement board or tile backer is attached 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 avoid standing water.
- Setting Valves, Drains, and Supply Lines — Skilled tradespeople on our crew position the new rough-in plumbing according to your fixture selections. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is positioned at this phase.
- Finishing the Shower Walls and Floor — Our finish crew set your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every seam is sealed and checked before the enclosure goes in.

- Completion Walk-Through and Finishing Touches — Once the full shower is complete, we perform a thorough quality review. Every seam at the perimeter are caulked with professional-grade caulk. We review with you the finished shower and make sure everything looks and functions as planned.
