Certified-used Master Spas Trainer 15 D: a 15-foot swim spa (180 x 94 inches, 60 inches deep, 1,595 gallons) with Master Spas' adjustable-speed swim current, 45 jets and bench seating for up to 12 when nobody is swimming. Sixty inches of depth gives a real swim stroke without hitting bottom. Same price as our Endless Pools X2000 and five feet shorter; the trade-off is footprint against the X2000's dual-temp design. Certified-used: stripped, tested under power, worn parts replaced, run on our floor.

New MSRP: $39,000 (the manufacturer's list price for this model when new). This is a certified-used unit — our price is the price shown.
