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 plumbing fixtures — is removed and replaced with a custom-fitted shower unit. The complexity of the project varies based on your existing bathroom footprint, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's location.
On a mechanical level, the process involves capping the existing tub drain and supply lines, lifting the tub unit and any tile, drywall, or backer board that was tied to it, then framing the new shower base with a proper slope toward the drain. New waterproofing membrane is applied before any surface covering goes up. Plumbing is rerouted to accommodate the new showerhead height and any additional fixtures you choose.
The finished product is a structurally sound shower that performs reliably for many years. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a thorough upgrade to your bathroom's plumbing, waterproofing, and layout.
