On a tight budget? Want a ?new? bathroom in a hurry? Do what hotels and motels do; drop one in. Today, you'll learn why one-day bath remodels are growing in popularity. Complete bathtubs, wall-surrounds and shower stalls, that just drop into place right over the old ones, were first made for the hotel and motel industry to quickly replace a damaged bath with minimal and costly downtime. New acrylic bathtub liners, perfectly molded to fit snugly over most standard brands of tubs, first are slipped into place. One-piece panels, covering each wall top to bottom, are then installed, with molded surfaces that imitate a variety of popular wall coverings -- from ceramic tile to marble and granite. New fixtures and a new shower door follow. In a matter of hours, a waterproof and leak-proof bath can be remodeled, with a gleaming tub, luxury walls and new hardware.
