What Really Is a Tub to Shower Conversion?

A tub to shower conversion is a home renovation service in which an existing bathtub — along with its framing and drain assembly — is taken out and replaced with a professionally installed shower unit. The scope of the project depends on your existing bathroom footprint, your design preferences, and whether you need to expand the shower's usable area beyond the original tub's location.

On a technical level, the project involves disconnecting the existing tub drain and supply lines, lifting the tub shell get more info and any surrounding wall material that was tied to it, then building out the new shower pan with a code-compliant slope toward the shower drain. New waterproofing membrane is installed before any surface covering goes on. Plumbing is modified to serve the new showerhead location and any additional fixtures you add.

The outcome is a code-compliant shower that drains correctly for many years. A tub to shower conversion done correctly is not just a visual change — it is a complete improvement to your bathroom's infrastructure and finish.

The Tub to Shower Conversion Procedure Step by Step

1. Initial Consultation and Planning — A member of our team meets with you on-site to assess your existing tub, plumbing, and bathroom layout. We review your goals, design preferences, and budget so the project plan aligns with exactly what you need.
