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 framing and drain assembly — is taken out and replaced with a purpose-built shower unit. The complexity of the project varies based on your existing bathroom layout, your finish selections, and whether you need to expand the shower's footprint beyond the original tub's location.
On a mechanical level, the project involves rerouting the existing tub drain and supply lines, taking out the tub shell and any surrounding wall material that was tied to it, then building out the new shower floor with a correct slope toward the drain. New waterproof liner is laid down before any tile, stone, or prefab panel goes up. Plumbing is modified to accommodate the new showerhead position and any body sprays, handheld wands, or rain heads you add.
The result is a fully waterproofed shower that drains correctly for many years. A tub to shower conversion done correctly is not just a cosmetic change — it is a complete improvement to your bathroom's infrastructure and finish.
