A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its enclosure and plumbing fixtures — is demolished 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 usable area beyond the original tub's position.
