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 drain assembly — is removed and replaced with a professionally installed shower unit. The scope of the project varies based on your existing bathroom layout, your design preferences, and whether you need to expand the shower's usable area beyond the original tub's location.
On a mechanical level, the project involves capping the existing tub drain and supply lines, taking out the tub shell and any surrounding wall material that was tied to it, then building out the new shower base 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 fit the new showerhead position and any body sprays, handheld wands, or rain heads you select.
The outcome is a code-compliant shower that drains correctly for the long term. A tub to shower conversion done correctly is not just a surface-level change — it is a thorough improvement to your bathroom's infrastructure and finish.
