What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its enclosure and hardware — is demolished 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 need to expand the shower's usable area beyond the original tub's location.
On a technical level, the process involves rerouting the existing tub drain and supply lines, removing the tub shell and any old tile surround that was tied to it, then framing the new shower pan with a proper slope toward the drain. New waterproofing membrane is applied before any tile, stone, or prefab panel goes up. Plumbing is modified to fit the new showerhead position and any body sprays, handheld wands, or rain heads 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 complete improvement to your bathroom's infrastructure and finish.
