Come in from the cold to the comfort of the J-345. The first time many of us experience the warm, bubbling waters of a spa may have been on a cold winter's day at a ski resort. Nothing does more to warm and loosen muscles and joints than an invigorating hydrotherapeutic massage. The J-345 is known for its big, round corners, which give everybody room to get loose in unrestricted comfort. One more reason to relax - your jacuzzi Premium spa includes a locking control panel to prevent anyone from interfering with the settings.
