What Actually 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 hardware — is demolished and replaced with a custom-fitted shower unit. The scope of the project varies based on your existing bathroom plumbing configuration, your style choices, and whether you want to expand the shower's square footage beyond the original tub's position.
On a mechanical level, the project involves capping the existing tub drain and supply lines, taking out the tub shell and any surrounding wall material that was tied to it, then building out the new shower base with a correct slope toward the shower drain. New waterproofing membrane is applied before any surface covering goes in. Plumbing is modified to fit the new showerhead height and any additional fixtures you add.
The result is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done correctly is not just a visual change — it is a thorough upgrade to your bathroom's structure and usability.
