What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its framing and hardware — is taken out and replaced with a custom-fitted shower unit. The scope of the project varies based on your existing bathroom footprint, your style choices, and whether you plan to expand the shower's usable area beyond the original tub's location.
On a structural level, the work involves rerouting the existing tub drain and supply lines, lifting the tub itself and any old tile surround that was tied to it, then constructing the new shower floor with a code-compliant slope toward the drain. New waterproof liner is laid down before any surface covering goes up. Plumbing is adjusted to serve the new showerhead height and any additional fixtures you choose.
The result is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a fundamental improvement to your bathroom's infrastructure and finish.
