Before plumbing, water only came indoors via endless chains of buckets or the pockets of unsuspecting scuba divers. Let water run freely with today's Groupon: for $100, you get $200 worth of kitchen and bathroom fixtures at Designer Bath and Salem Plumbing Supply in Beverly.

Designer Bath and Salem Plumbing Supply, which Northshore Magazine editors and readers voted as the best bath supplies store in the North Shore area, equips homeowners with a vast assortment of kitchen and bathroom furnishings from dozens of brands, including Dornbracht, Duravit, and Fairmont. Contemporary designs and classic models dot a 4,500-square-foot showroom, where a knowledgeable staff helps customers select the polished chrome towel bar ($34) or two-robe bathroom hook ($15) that best matches their lucky hubcap. An American Standard single-lever kitchen faucet expels water through a sprayer ($75), and a Grohe showerhead unleashes jets of moisture from a 6-inch-wide chrome disk ($63). Two levels of magnification power on a double-sided Kimball & Young vanity makeup mirror ($107) provide an up-close view for poring over pores or communicating face-to-face with the tiny pilots in your eyeballs. Designer Bath and Salem Plumbing Supply does not provide installation.
