Towel warmers find a place in American baths Novice American travelers are often mystified by the heated towel racks in European hotel rooms. But it will probably become a more familiar sight in the next few years. Towel heaters are actually radiators with bars for drying dampened towels. Designers say the racks help keep bathrooms and towels dry and mildew free. Plus they are a pleasure to use after a shower. American manufacturers are now promoting towel warmers, some with aromatherapy and other perks. At Amba Products in Marietta, Ga., a distributor of decorative hardware, they say the Italian-made Quadro collection features square bars and a digital controller with nine heat settings. The starting price is $620. It doesn't include the cost of installation, which may require water or electrical connections. Mr. Steam, a bath products company based in Long Island, N.Y., offers an aromatherapy feature in its Broadway Collection. They recommend filling the aromatherapy well with eucalyptus essential oil. The price is $1,250 for the 48-by-20-inch oil-rubbed-bronze model, plus $275 for a matching robe hook, digital timer and the oil. Signature Hardware in Erlanger, Ky., offers a hard-wired steel towel rack with 23 rails for towels. Bars are filled with a liquid that, when warmed evenly, heats towels. It costs $449 for a 30-inch unit.
