What Actually Is a Tub to Shower Conversion?

A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its enclosure and hardware — is taken out and replaced with a purpose-built shower unit. The scope of the project depends on your existing bathroom layout, your finish selections, and whether you need to expand the shower's usable area beyond the original tub's position.

On a technical level, the process involves rerouting the existing tub drain and supply lines, removing the tub shell and any surrounding wall material that was tied to it, then building out the new shower pan with a code-compliant slope toward the drain. New waterproofing membrane is installed before any finish material goes on. Plumbing is modified to fit the new showerhead location here and any extra spray features you select.

The finished product is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done right is not just a visual change — it is a complete upgrade to your bathroom's structure and usability.
