What Actually Is a Tub to Shower Conversion?

A tub to shower conversion is a home renovation service in which an existing bathtub — along with its enclosure and hardware — is demolished and replaced with a purpose-built shower unit. The scale of the project is shaped by your existing bathroom layout, your style choices, and whether you need to expand the shower's usable area beyond the original tub's position.

On a technical level, the work involves rerouting the existing tub drain and supply lines, lifting the tub shell and any tile, drywall, or backer board that was tied to it, then framing the new shower base with a proper slope toward the shower drain. New waterproof liner is applied before any tile, stone, or prefab panel goes in. Plumbing is adjusted to accommodate the new showerhead position and any body sprays, handheld wands, or rain heads you select.

The outcome is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done right is not just a cosmetic change — it is a fundamental transformation to your bathroom's plumbing, waterproofing, and layout.

6. Hanging Doors, Glass, or Hardware — Depending on your design choice, we hang your shower door or curtain hardware. All hardware is anchored properly to provide a solid, long-lasting result.
7. Final Inspection, Grouting, and Caulking — Once everything is tiled, grouted, and enclosed, we perform a thorough final inspection. Each transition joint at corners and the floor-to-wall transition are caulked with flexible waterproof sealant. We review with you the finished shower and make sure everything meets your expectations.
