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 scope of the project varies based on your existing bathroom layout, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's space.
On a structural level, the project involves disconnecting the existing tub drain and supply lines, lifting the tub itself and any tile, drywall, or backer board that was tied to it, then framing the new shower floor with a correct slope toward the drain. New waterproofing membrane is installed before any surface covering goes up. Plumbing is rerouted to accommodate the new showerhead position and any additional fixtures you select.
The result is a code-compliant shower that performs reliably for many years. A tub to shower conversion done right is not just a cosmetic change — it is a thorough improvement to your bathroom's structure and usability.

New waterproof backer material is screwed to the framing, and a full waterproofing membrane is installed across all wet surfaces. The shower pan is graded toward the drain to avoid standing water.
