Welcome to our forum.
I suggest you look at a Bullfrog R6. That is their offering that closest meeets your requirements. It has three jetpaks as standard with that tub, three seats with built-in jets, a cool down seat and a pair of footjets.There are a few good reasons to buy a Bullfrog. The jetpaks come in sixteen different varieties. I have experience with a HotSprings Envoy and I can say that there is no comparison with the Bullfrog jetpaks. The Envoy has a lounge seat with the dual MotoMassage. It's the least used seat in the tub.With your seating requirements, you'll need to stay away from a spa with a lounger. There is a common tale of people buying their first hot tub with a lounger; the second time 'round, they buy without. I agree with that. It seems like a good idea that you lay down and relax in the lounger. The reality is that it usually takes up a whole side of space in the tub. So, where you could have two or three seats, you have one lounger. Also, any seat can be operated close to a lounger, in that, when you're in a hot tub you are naturally buoyant and can float by angling away from the seat.Bullfrog has an optional WellSpring filtration pump which uses a much lower energy draw pump to circulate water for filtration. It's a couple to few hundred dollar option. Also, there is the WellSpring high-output Ozone generator. This helps break down the body soaps and oils. Chlorine alone cannot do this. A couple of hundred dollar option.Both HotSprings and Bullfrogs are extremely well insulated. In Michigan, that can help keep the electric bill reasonable.I believe Bullfrog is having a $500 rebate on their spas beginning around Thanksgiving until the end of the year.You should definitely wet test the unit. They can change jetpaks in under a minute, so you can test all the different ones available. To get a good taste right from the get-go, I'd have them put in the Gyrossage, Pulsator and Oscillator. Then, after you've had time with them, swap them and try the NeckBlaster and Rainshower--which is many times utilized to relax in after you've done hydrotherapy with the others. The most important thing for you to do is to go look at the Bullfrogs, find one you like and can afford--even if it means stretching the budget and then make a no obligation appointment to wet test it. And then spend time playing with the setting on each jetpak and foot jet. The jetpaks have a dial on the lower part of the jetpak and that is how you adjust the jet power. Make sure the jet pumps are on the high speed. I think you will be impressed with how effective the jetpaks are. Don't expect every hot tub to feel this way. There is a world of difference with the Bullfrog jetpaks. You can buy additional jetpaks-- but they can be pricey (~$500 or so.). When you wet test have the dealer give you a catalog which shows the different jetpaks and then write notes after testing each one. Otherwise you may forget which is which. You get only three standard in the R6; you want to make a careful selection.Buying new in the R-series will also give you a good warranty. Repairs on hot tubs can be expensive. There's much less internal plumbing in the Bullfrog spas which reduces chances of leaks. Repairing an out-of-warranty leak in a fully foamed spa can exceed $2000; and with good reason: it is difficult to locate leaks and it's a lot of labor and involvement.Do yourself a favor and go check out the Bullfrogs and wet test, taking notes about the jetpak performances. You may also want to look into purchasing a Capo deluxe spa pillow; it's arguably the best one out there. It can make the spa more functional and enjoyable for the shorter members of your family and friends.You will be impressed with the jetpak performance. All spas heat water, have jets and filtration. It's just that the Bullfrog jets are better, in my opinion, by a wide, wide margin. They are one of the most energy efficient, too.That's my carefully thought out advice and I hope you take it into consideration and post back on your buying experience.Good luck!
