What Exactly 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 plumbing fixtures — is taken out and replaced with a purpose-built shower unit. The scale of the project is shaped by your existing bathroom footprint, your style choices, and whether you need to expand the shower's square footage beyond the original tub's location.
On a structural level, the project involves rerouting the existing tub drain and supply lines, lifting the tub itself and any old tile surround that was tied to it, then constructing the new shower floor with a proper slope toward the shower drain. New waterproofing membrane is laid down before any tile, stone, or prefab panel goes in. Plumbing is adjusted to serve the new showerhead position and any body sprays, handheld wands, more info or rain heads you add.
The result is a code-compliant shower that drains correctly for many years. A tub to shower conversion done right is not just a visual change — it is a complete improvement to your bathroom's structure and usability.
