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 surround and drain assembly — is demolished and replaced with a custom-fitted shower unit. The scope of the project is shaped by your existing bathroom footprint, your style choices, and whether you plan to expand the shower's footprint beyond the original tub's location.

On a technical level, the process involves disconnecting 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 code-compliant slope toward the shower drain. New waterproofing membrane is installed before any finish material goes in. Plumbing is adjusted to accommodate the new showerhead location and any body sprays, handheld wands, or rain heads you add.

The finished product is a structurally sound shower that drains correctly for the long term. A tub to shower conversion done right is not just a surface-level change — it is a thorough transformation to your bathroom's infrastructure and finish.
