What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its framing and drain assembly — is demolished and replaced with a custom-fitted shower unit. The scale of the project depends on your existing bathroom layout, your style choices, and whether you want to expand the shower's square footage beyond the original tub's space.
On a structural level, the project involves capping the existing tub drain and supply lines, removing the tub itself and any old tile surround that was tied to it, then framing the new shower floor with a proper slope toward the drain. New moisture barrier is laid down before any tile, stone, or prefab panel goes on. Plumbing is modified to accommodate the new showerhead position and any body sprays, handheld wands, or rain heads you select.
The finished product is a structurally sound shower that functions properly for many years. A tub to shower conversion done right is not just a visual change — it is a thorough transformation to your bathroom's infrastructure and finish.
