What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and drain assembly — is removed and replaced with a custom-fitted shower unit. The scope of the project is shaped by your existing bathroom layout, your style choices, and whether you want to expand the shower's usable area beyond the original tub's space.
On a mechanical level, the process involves rerouting the existing tub drain and supply lines, lifting the tub itself and any old tile surround that was tied to it, then building out the new shower pan with a code-compliant slope toward the center drain. New waterproof liner is applied before any finish material goes in. Plumbing is modified to fit the new showerhead location and any extra spray features you add.
The outcome is a fully waterproofed shower that functions properly for the long term. A tub to shower conversion done right is not just a surface-level change — it is a thorough improvement to your bathroom's structure and usability.

- Completion Walk-Through and Finishing Touches — Once all surfaces is finished and installed, we do a thorough quality review. Each transition joint at the base and wall corners are finished with flexible waterproof sealant. We review with you the final result and confirm everything meets your expectations.
