Don’t jump too quickly to discard reusable fixtures. If your tub is in relatively good shape, consider having it re-glazed instead of replaced, according to the National Association of the Remodeling Industry. As for the walls around the tub, cultured marble sheets are cheaper to install than marble tiles and also easier to clean. Fiberglass is also less expensive than tile. If space is extremely limited and you cannot “steal” it from other areas of your home, purchase a jetted tub and shower combination or install a pedestal lavatory instead of a vanity cabinet with a sink. Remember, installing a large jetted tub can overtax your water heater, so consider adding a water heater that is dedicated to the tub to prevent problems later.
