What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its enclosure and plumbing fixtures — is demolished and replaced with a custom-fitted shower unit. The complexity of the project is shaped by your existing bathroom plumbing configuration, your design preferences, 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, lifting the tub unit and any tile, drywall, or backer board that was tied to it, then building out the new shower floor with a correct slope toward the center drain. New waterproofing membrane is applied before any surface covering goes up. Plumbing is adjusted to accommodate the new showerhead height and any extra spray features you choose.
The outcome is a structurally sound shower that drains correctly for decades. A tub to shower conversion done right is not just a visual change — it is a complete upgrade to your bathroom's infrastructure and finish.
