A tub to shower conversion is a home renovation service in which an existing bathtub — along with its enclosure and plumbing fixtures — is demolished and replaced with a custom-fitted shower unit. The scale of the project is shaped by your existing bathroom footprint, your style choices, and whether you need to expand the shower's footprint beyond the original tub's position.
On a mechanical level, the project involves capping the existing tub drain and supply lines, taking out the tub unit and any surrounding wall material that was tied to it, then framing the new shower base with a correct slope toward the shower drain.

The finished product is a structurally sound shower that performs reliably for decades. A tub to shower conversion done by experienced hands is not just a visual change — it is a thorough upgrade to your bathroom's infrastructure and finish.
