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 enclosure and hardware — website is demolished and replaced with a custom-fitted shower unit. The scope of the project depends on your existing bathroom footprint, your finish selections, and whether you plan to expand the shower's footprint beyond the original tub's position.
On a structural level, the project involves disconnecting the existing tub drain and supply lines, removing the tub itself and any old tile surround that was tied to it, then building out the new shower base with a proper slope toward the drain. New waterproof liner is laid down before any surface covering goes on. Plumbing is modified to fit the new showerhead height and any additional fixtures you choose.
The result is a fully waterproofed shower that functions properly 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 infrastructure and finish.
