This is the swimming pool that allows swimmers to practice laps in a space the size of an SUV. At only 65' sq., the pool sets up in garages, backyards, basements, or rec rooms. It uses a harness that wraps around a swimmer's waist (22-42" waists) and a flexible elastic tether that suspends swimmers in the water, providing varying resistance--stronger strokes and kicks yield more resistance. Requiring no special tools, plumbing, or electrical work for installation, the 4 1/2'-high pool can be filled with 1,500 gallons of fresh, chlorinated, or saltwater--the included pump and filter maintains optimal water cleanliness. Supported by a sturdy powder-coated steel frame, the pool's liner is made from rip- and tear-resistant PVC-coated 2,000-denier polyester fabric; the included floor mat provides further protection for the pool's bottom. A built-in ladder provides easy entries and exits. Includes cover. 10' L x 7' W x 7 1/2" H. (207 lbs.)
