What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The complexity of the project depends on your existing bathroom footprint, your finish selections, and whether you want to expand the shower's usable area beyond the original tub's space.
On a mechanical level, the work involves disconnecting the existing tub drain and supply lines, lifting the tub itself and any surrounding wall material that was tied to it, then building out the new shower base with a proper slope toward the center drain. New waterproofing membrane is laid down before any surface covering goes in. Plumbing is rerouted to serve the new showerhead position and any extra spray features you add.
The result is a structurally sound shower that performs reliably for decades. A tub to shower conversion done by experienced hands is not just a visual change — it is a fundamental upgrade to your bathroom's plumbing, waterproofing, and layout.
