Jamiaican extreme swim spa 307 l x 90 w x 61 h. It is a removable option that, when installed, allows you to row for exercise. The Stainless Steel Grab Bar can be mounted above the swim jets in the swim zone. This allows you to hold onto the bar while kicking or doing lighter exercises in the current. Was filled with water maybe less than a year. Total use was only about 10 times. We drained years ago than cover it up and never used it again as we’ve been really busy with work and family the past few years. We planned on building a deck around it but just don’t have any time. Takes a lot of work to maintain a hot tub this big which we weren’t prepared for as well. Asking 15000 Feel free to contact me if you have any questions.
