A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and hardware — is removed and replaced with a custom-fitted shower unit. The scope of the project depends on your existing bathroom layout, your design preferences, and whether you want to expand the shower's usable area beyond the original tub's location.

New waterproof liner is installed before any finish material goes on. Plumbing is rerouted to serve the new showerhead position and any extra spray features you choose.
The result is a fully waterproofed shower that functions properly for many years. A tub to shower conversion done right is not just a visual change — it is a fundamental transformation to your bathroom's infrastructure and finish.
