What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its surround and hardware — is demolished and replaced with a purpose-built shower unit. The complexity of the project varies based on your existing bathroom layout, your finish selections, and whether you want to expand the shower's usable area beyond the original tub's space.
On a structural level, the project involves capping the existing tub drain and supply lines, lifting the tub shell 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 waterproof liner is laid down before any tile, stone, or prefab panel goes in. Plumbing is adjusted to fit the new showerhead location and any additional fixtures you add.
The finished product is a code-compliant shower that drains correctly for the long term. A tub to shower conversion done correctly is not just a visual change — it is a fundamental upgrade to your bathroom's structure and usability.

Who Is a Good Candidate for a Tub to Shower Conversion?
