What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its framing and plumbing fixtures — is demolished and replaced with a custom-fitted shower unit. The scope of the project depends on your existing bathroom footprint, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's position.
On a technical level, the project involves disconnecting the existing tub drain and supply lines, taking out the tub unit and any old tile surround that was tied to it, then constructing the new shower pan with a code-compliant slope toward the shower drain. New waterproofing membrane is applied before any tile, stone, or prefab panel goes on. Plumbing is rerouted to accommodate the new showerhead position and any extra spray features you select.
The finished product is a structurally sound shower that drains correctly for decades. A tub to shower conversion done correctly is not just a visual change — it is a complete transformation to your bathroom's plumbing, waterproofing, and layout.
