What Actually 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 hardware — is taken out and replaced with a custom-fitted shower unit. The scope of the project is shaped by your existing bathroom footprint, your finish selections, and whether you want to expand the shower's square footage beyond the original tub's position.
On a structural level, the work involves capping the existing tub drain and supply lines, removing the tub shell and any old tile surround that was tied to it, then building out the new shower floor with a correct slope toward the center drain. New moisture barrier is installed before any finish material goes on. Plumbing is modified to serve the new showerhead height and any additional fixtures you choose.
The finished product is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done right is not just a visual change — it is a fundamental upgrade to your bathroom's structure and usability.
