What Exactly 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 demolished and replaced with a custom-fitted shower unit. The scale of the project varies based on your existing bathroom footprint, your finish selections, and whether you need to expand the shower's usable area beyond the original tub's location.
On a structural level, the work involves disconnecting the existing tub drain and supply lines, removing the tub itself and any old tile surround that was tied to it, then constructing the new shower base with a proper slope toward the center drain. New waterproofing membrane is laid down before any tile, stone, or prefab panel goes in. Plumbing is rerouted to accommodate the new showerhead height and any extra spray features you choose.
The finished product is a fully waterproofed shower that functions properly for many years. A tub to shower conversion done right is not just a cosmetic change — it is a complete upgrade to your bathroom's infrastructure and finish.
