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 enclosure and drain assembly — is taken out and replaced with a professionally installed shower unit. The complexity of the project depends on your existing bathroom plumbing configuration, your design preferences, and whether you need to expand the shower's usable area beyond the original tub's space.
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 constructing the new shower floor with a code-compliant slope toward the drain. New waterproof liner is applied before any finish material goes up. Plumbing is adjusted to fit the new showerhead height and any additional fixtures you select.
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 surface-level change — it is a thorough upgrade to your bathroom's plumbing, waterproofing, and layout.
Major Benefits of a Tub to Shower Conversion

- Simpler Upkeep — Shower surrounds and bases are typically faster to clean and maintain than a full-length bathtub with hard-to-reach corners.

- Structural Prep and Moisture Barrier Installation — This is widely considered the most critical stage of a tub to shower conversion. New cement board or tile backer is fastened to the wall studs, and a full waterproofing membrane is installed across the shower floor and lower walls.

- Hanging Doors, Glass, or Hardware — Depending on your selected style, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. All hardware is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Final Inspection, Grouting, and Caulking — Once the full shower is complete, we do a thorough quality review. Every seam at corners and the floor-to-wall transition are caulked with professional-grade caulk. We review with you the final result and verify everything looks and functions as planned.
