What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its framing and hardware — is taken out and replaced with a custom-fitted shower unit. The scale of the project depends on your existing bathroom plumbing configuration, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's location.
On a structural level, the work involves capping the existing tub drain and supply lines, lifting the tub itself and any old tile surround that was tied to it, then building out the new shower base with a code-compliant slope toward the center drain. New waterproof liner is installed before any tile, stone, or prefab panel goes in. Plumbing is adjusted to serve the new showerhead position and any extra spray features you choose.
The finished product is a code-compliant shower that drains correctly for decades. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a fundamental transformation to your bathroom's structure and usability.
