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 taken out and replaced with a purpose-built shower unit. The complexity of the project varies based on your existing bathroom footprint, your finish selections, and whether you plan to expand the shower's footprint beyond the original tub's location.
On a technical level, the project involves capping the existing tub drain and supply lines, taking out the tub unit and any tile, drywall, or backer board that was tied to it, then framing the new shower floor with a proper slope toward the shower drain. New waterproofing membrane is applied before any finish material goes on. Plumbing is modified to fit the new showerhead position and any body sprays, handheld wands, or rain heads you choose.
The result is a code-compliant shower that drains correctly for the long term. A tub to shower conversion done correctly is not just a cosmetic change — it is a complete upgrade to your bathroom's structure and usability.
