What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its framing and hardware — is demolished and replaced with a custom-fitted shower unit. The scope of the project varies based on your existing bathroom plumbing configuration, your design preferences, and whether you need to expand the shower's square footage beyond the original tub's location.

New waterproofing membrane is laid down before any surface covering goes on. Plumbing is rerouted to serve the new showerhead position and any extra spray features you add.
The result is a code-compliant shower that functions properly for decades. A tub to shower conversion done right is not just a cosmetic change — it is a complete improvement to your bathroom's infrastructure and finish.
