This was an in-ground installation of an exercise pool. It is dual temperature unit. The hot tub runs at a higher temperature than the swimming pool section. This unit comes with a hard insulation cover if going outside. We provide a light thermal blanket for retaining the heat when installed inside. The acrylic shell is fibreglass backed for additional strength. This swimspa comes completed plumbed ready for installation. If going in ground all the equipment is plumbed on site. The interior lights give a wonderful feel to this domestic exercise pool. Lower maintenance than the traditional swimming pool, lower cost to run and takes up less space in the smaller urban garden - even installed inside basement before new builds..
