New waterproofing membrane is applied before any tile, stone, or prefab panel goes up. Plumbing is rerouted to fit the new showerhead position and any body sprays, handheld wands, or rain heads you choose.

The finished product is a structurally sound shower that drains correctly for many years. A tub to shower conversion done right more info is not just a visual change — it is a thorough upgrade to your bathroom's infrastructure and finish.
