Copper tubs are way cool, but they aren’t that unique. They are expensive, though. Kohler’s Kallista brand makes one (see it here) that can be yours if you’re willing to pony up a cool $68,968. Sunrise Specialty is set to unveil one that is way cheaper because, unlike other copper tubs, the Piedmont #874 freestanding unit is made from copper leaf applied over cast-iron steel. The tub also features a vitreous porcelain interior. Set for release on July 1, 2011, the tub will retail for a mere $7,500. www.sunrisespecialty.com.
