What Really 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 hardware — is taken out and replaced with a purpose-built shower unit. The scale of the project is shaped by your existing bathroom footprint, your style choices, and whether you need to expand the shower's usable area beyond the original tub's space.

On a technical level, the work involves disconnecting 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 building out the new shower base with a proper slope toward the center drain. New moisture barrier is applied before any finish material goes on. Plumbing is modified to accommodate the new showerhead location and any extra spray features you add.

The result 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 structure and usability.

6. 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. Every mounting bracket is set into the tile or framing to provide a solid, long-lasting result.
7. Final Inspection, Grouting, and Caulking — Once everything is tiled, grouted, and enclosed, we perform a thorough walk-through. Each transition joint at the perimeter are sealed with flexible waterproof sealant. We review with you the final result and confirm everything is exactly what you wanted.
