What Actually Is a Tub to Shower Conversion?

A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and hardware — 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 want to expand the shower's usable area beyond the original tub's location.

On a structural level, the project involves capping the existing tub drain and supply lines, taking out the tub unit and any surrounding wall material that was tied to it, then building out the new shower floor with a code-compliant slope toward the drain. New waterproof liner is applied before any tile, stone, or prefab panel goes up. Plumbing is rerouted to fit the new showerhead height and any additional fixtures you add.

The outcome is a fully waterproofed shower that functions properly for the long term. A tub to shower conversion done right is not just a cosmetic change — click here it is a complete improvement to your bathroom's infrastructure and finish.

Stronger Home Appraisals — Updated bathrooms reliably appear among the highest-ROI upgrades for resale. A tub to shower conversion communicates updated finishes to real estate agents.

The Tub to Shower Conversion Procedure Step by Step

Project Assessment and Design — A project consultant meets with you on-site to measure your existing space and infrastructure. We discuss your must-haves and finish choices so the project plan matches exactly what you want.
Removal of the Existing Tub and Surround — The existing tub unit and wall material are demolished and cleared. Supply and drain lines tied to the old tub are properly shut off to prepare for the new shower plumbing layout.
Framing, Waterproofing, and Substrate Work — 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 floor base is graded toward the drain to prevent pooling.
Setting Valves, Drains, and Supply Lines — Skilled tradespeople on our crew position the new rough-in plumbing according to your design plan. Whether you selected a basic or premium shower setup, everything is positioned at this phase.
Applying Your Chosen Finish Materials — Our finish crew set your selected finish material using professional-grade installation materials. Every grout joint is grouted and reviewed before the enclosure goes in.
Installing the Shower Enclosure — Depending on your selected style, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Each component is set into the tile or framing to prevent loosening over time.
Completion Walk-Through and Finishing Touches — Once the full shower is tiled, grouted, and enclosed, we conduct a room-by-room walk-through. Every seam at corners and the floor-to-wall transition are sealed with flexible waterproof sealant. We walk you through the finished shower and verify everything looks and functions as planned.
