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 enclosure and plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The scale of the project is shaped by your existing bathroom plumbing configuration, your finish selections, and whether you need to expand the check here shower's square footage beyond the original tub's location.

New waterproof liner is applied before any tile, stone, or prefab panel goes on. Plumbing is modified to fit the new showerhead height and any additional fixtures you select.
The outcome is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done correctly is not just a visual change — it is a thorough improvement to your bathroom's plumbing, waterproofing, and layout.
