Yes, every dome includes a beautiful Canadian made hot tub at no additional charge. Our hot tubs are ready for this climate and are therefore useable all winter long. We are extremely committed to perfectly clean water, so your hot tub is rigorously cleaned and maintained with all PH balancing, alkalinity, calcium and chlorine testing done after every guest. Water is tested daily and changed regularly to ensure top water quality for our guests. Please check out our handy binder on the table which includes an easy how to guide if you have any hot tub questions.
