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 hardware — is taken out and replaced with a custom-fitted shower unit. The complexity of the project depends on your existing bathroom layout, your finish selections, and whether you need to expand the shower's footprint beyond the original tub's position.
On a structural level, the process involves disconnecting the existing tub drain and supply lines, taking out the tub shell and any tile, drywall, or backer board that was tied to it, then building out the new shower pan with a proper slope toward the shower drain. New waterproofing membrane is installed before any surface covering goes on. Plumbing is adjusted to accommodate the new showerhead height and any additional fixtures you choose.
The result is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a fundamental improvement to your bathroom's plumbing, waterproofing, and layout.
