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 surround and plumbing fixtures — is removed and replaced with a custom-fitted shower unit. The scope of the project depends on your existing bathroom footprint, your design preferences, and whether you plan 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, lifting the tub itself and any surrounding wall material that was tied to it, then framing the new shower floor with a code-compliant slope toward the center drain. New waterproof liner is applied before any finish material goes up. Plumbing is rerouted to serve the new showerhead height and any additional fixtures you select.
The finished product is a fully waterproofed shower that functions properly for the long term. A tub to shower conversion done by experienced hands is not just a visual change — it is a complete upgrade to your bathroom's plumbing, waterproofing, and layout.
