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 surround and drain assembly — is taken out and replaced with a professionally installed shower unit. The complexity of the project depends on your existing bathroom layout, your finish selections, and whether you want 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 unit and any tile, drywall, or backer board that was tied to it, then constructing the new shower pan with a correct slope toward the shower drain. New moisture barrier is applied before any finish material goes in. Plumbing is modified to serve the new showerhead position and any extra spray features you choose.
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 visual change — it is a complete transformation to your bathroom's plumbing, waterproofing, and layout.
Major Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs take up between 13 and 16 square feet. Converting to a custom shower stall returns that room to usable, open bathroom space.

The Tub to Shower Conversion Procedure 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 discuss your wishlist and timeline so the project plan reflects exactly what you have in mind.
- Removal of the Existing Tub and Surround — 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 revised drain placement.
- Framing, Waterproofing, and Substrate Work — This is widely considered the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is attached to the wall studs, and a continuous waterproof layer is applied across all wet surfaces. The shower pan is pitched properly to ensure drainage.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew set the new plumbing fixtures according to your chosen layout. Whether you selected a standard showerhead or an upgraded fixture package, everything is installed at this point.
- Tile, Stone, or Panel Installation — Skilled installers apply your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every seam is finished and inspected before glass or curtain hardware is installed.
- Glass Enclosure, Door, or Curtain Rod Installation — 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 anchored properly 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. All caulk joints at corners and the floor-to-wall transition are sealed with mold-resistant silicone caulk. We walk you through the finished shower and confirm everything is exactly what you wanted.
