What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its framing and drain assembly — is demolished and replaced with a professionally installed shower unit. The scale of the project depends on your existing bathroom footprint, your style choices, and whether you plan to expand the shower's square footage beyond the original tub's location.
On a mechanical level, the process involves disconnecting the existing tub drain and supply lines, taking out the tub unit and any surrounding wall material that was tied to it, then constructing the new shower floor with a proper slope toward the drain. New waterproofing membrane is applied before any tile, stone, or prefab panel goes on. Plumbing is adjusted to accommodate the new showerhead height and any extra spray features you add.
The result is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done by experienced hands is not just a visual change — it is a fundamental transformation to your bathroom's plumbing, waterproofing, and layout.
