What Really Is a Tub to Shower Conversion?

The complexity of the project depends on your existing bathroom layout, your style choices, and whether you plan to expand the shower's usable area beyond the original tub's position.

Plumbing is rerouted to serve the new showerhead location and any body sprays, handheld wands, or rain heads you choose.
