A tub to shower conversion is a home renovation service in which an existing bathtub — along with its framing and drain assembly — is removed and replaced with a purpose-built shower unit. The scale of the project depends on your existing bathroom plumbing configuration, your style choices, and whether you need to expand the shower's footprint beyond the original tub's position.
