If you are considering purchasing a Thermospas Hot Tub be aware that the sales person will tell you all about their long warranties on the shell and the electronics, but they will fail to tell you that the base is made of particle board and only has a 3 year warranty.When I turned my expensive Manhattan Platinum on the 4th season, the diverter valves blew out of the unit with a 2" column of water blowing into the air.
I shut the unit down and opened the side of the unit to see that the base had sagged and the heavy 2" hose had pulled the diverter valve down with the base as it sagged and made it impossible to reconnect the valves. When I called for service they told me that it was not under warranty and I would be responsible for rebuilding the unit at my own expense.
So in reality they could give you a 100 year warranty on the shell because they know the base will cause the unit to be worthless long before the shell gives way.Don't Buy a Thermospas!!!
