Welcome to our forum.
Lookin' for some hard core facts to help me make my decision.
I see the Lotus Bay on your list. Out of curiosity, did you check into the Arctic Tundra (if you have a dealer reasonable close). I didn't see Arctic on your overall "checked into" list. It too is a captain seat in each corner layout in a full 8x8 tub.
Does the Arctic come with a massage sequencer and double chamber ozone system standard?
No, it gives an excellent massage without gimmicky stuff like massage sequencers. A large majority of the jets actually rotate with several different patterns available. These are not the same "spinners" found on other spas based on my research. With the peak ozone system certified at 500mg of ozone per hour, it only needs one ozone system to be effective . It's a very comfortable tub. I know what you were implying. The Lotus is a nice tub, but the Tundra is a nice alternative to consider.
