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 surround and drain assembly — is taken out and replaced with a professionally installed shower unit. The complexity of the project varies based on your existing bathroom layout, your style choices, and whether you plan to expand the shower's footprint beyond the original tub's space.
On a structural level, the process 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 constructing the new shower pan with a correct slope toward the shower drain. New waterproof liner is installed before any tile, stone, or prefab panel goes in. Plumbing is modified to serve the new showerhead height and any body sprays, handheld wands, or rain heads you choose.
The outcome is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done right is not just a visual change — it is a complete improvement to your bathroom's plumbing, waterproofing, and layout.
