Welcome to our forum.
I have to disagree with most of the comments here so far.
The softubs have become a bit pricey for what they offer. In the $2500 -3500 range which softub is in, you can purchase, a real hard sided hot tub, not soft sided. Manufacturers such as Nordic, Free Flow and Viking, to name a few, offer tubs in the $2500-4000 range. The big difference will be a spa with comfortable seating, instead of sitting on the floor of the flat soft tub. As stated earlier, Softub has no heater, so look for initial heat up times, for fresh water at about 36-48 hours. The other brands offer 110/220 volt convertible spa equipment, with a regular heater, like top brands. With a soft sided spa you end up with 4 or 5 jets, compared to about 20 jets with Nordic, Free Flow and Viking. With a hard sided tub, look for a much longer life expectancy, especially in areas prone to cold temperatures. Dave.
