What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its enclosure and drain assembly — is removed and replaced with a professionally installed shower unit. The complexity of the project is shaped by your existing bathroom footprint, your design preferences, and whether you want to expand the shower's square footage beyond the original tub's position.
On a technical level, the project involves capping the existing tub drain and supply lines, taking out the tub unit and any surrounding wall material that was tied to it, then building out the new shower pan with a correct slope toward the drain. New waterproofing membrane is laid down before any surface covering goes in. Plumbing is adjusted to serve the new showerhead height and any additional fixtures you select.
The result is a fully waterproofed shower that performs reliably for the long term. A tub to shower conversion done correctly is not just a surface-level change — it is a fundamental transformation to your bathroom's structure and usability.
