How long does it take to fill the hot tub?

It usually takes about 60 minutes to fill the 4-person hot tub at standard household water pressure and 75 minutes to fill the 6-person hot tub. We recommend filling the tub with warm water to reduce the heat-up time. Our high wattage spa pumps heat at approximately 1 hour per degree, so cut out the middle man and start at a high temperature!
