Thinking About a Tub to Shower Conversion? Read This First
A well-planned tub to shower conversion can dramatically improve how you use your bathroom every single morning. For countless homeowners, the standard bathtub occupies valuable floor space while sitting empty for months at a time. A tub to shower conversion swaps out that underused tub with a spacious walk-in shower that fits the way you actually move through your home.

Whether you are updating an outdated space or simply prefer a more efficient shower setup, this guide walks you through all the details — from how the process works to what marks someone an perfect candidate. Let's get started to find out whether a tub to shower conversion is the best option for your bathroom.
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 surround and plumbing fixtures — is demolished and replaced with a professionally installed shower unit. The scale of the project depends on your existing bathroom plumbing configuration, your finish selections, and whether you want to expand the shower's square footage beyond the original tub's space.
On a structural level, the process involves rerouting the existing tub drain and supply lines, removing the tub unit and any tile, drywall, or backer board that was tied to it, then building out the new shower base with a code-compliant slope toward the center drain. New waterproofing membrane is laid down before any surface covering goes up. Plumbing is rerouted to fit the new showerhead location and any additional fixtures you add.
The result is a fully waterproofed shower that performs reliably for many years. A tub to shower conversion done correctly is not just a surface-level change — it is a thorough upgrade to your bathroom's plumbing, waterproofing, and layout.
