Got a Hotspring Sovereign, had it about 9.5 years now.
Only had 2 small repairs done to it in that time.
Very happy with it.
Get a tub that seats 2 more than you require, we looked at the four seaters and found that its very cramped when 4 people get in a 4 seat tub. 6 seats are far more relaxing to stretch out in.
Don’t normally use our jets as we like to sit and chat without any phone/tv/computer disturbances once the kids go to bed. However, some jets are better than others. The fixed ones are a bit mleh but the rotating ones give a type of massage.
You know that hot tub shops will let you “test drive” them. You might have an audience but it’s a lot of money to fork out without trying one out first.
