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 hardware — is demolished 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 plan to expand the shower's usable area beyond the original tub's position.
On a mechanical level, the process involves rerouting the existing tub drain and supply lines, removing the tub shell and any old tile surround that was tied to it, then constructing the new shower pan with a proper slope toward the shower drain. New moisture barrier is laid down before any tile, stone, or prefab panel goes up. Plumbing is rerouted to fit the new showerhead position and any additional fixtures you choose.
The result is a structurally sound shower that drains correctly for decades. A tub to shower conversion done correctly is not just a cosmetic change — it is a thorough upgrade to your bathroom's structure and usability.

- Quality Check and Project Sign-Off — Once everything is tiled, grouted, and enclosed, we do a thorough final inspection. Every seam at the perimeter are sealed with mold-resistant silicone caulk. We review with you the finished shower and make sure everything looks and functions as planned.
