What Exactly 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 demolished and replaced with a custom-fitted shower unit. The complexity of the project depends on your existing bathroom footprint, your design preferences, and whether you need to expand the shower's usable area beyond the original tub's position.
On a structural level, the project involves capping the existing tub drain and supply lines, lifting the tub unit and any surrounding wall material that was tied to it, then framing the new shower base with a proper slope toward the center drain. New waterproofing membrane is laid down before any finish material goes in. Plumbing is adjusted to fit the new showerhead height and any extra spray features you select.
The finished product is a fully waterproofed shower that drains correctly for many years. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a fundamental upgrade to your bathroom's structure and usability.
