Welcome to our forum.
I soaked in one and thought it was a nice tub. But, the lounger is very long from hip to knee so I didn't get a natural leg bend and it wasn't comfortable for me. Their new jets in that lounger are great. If you are taller, it may fit you and you will probably love it. Wet test for sure. They've upped the price on the new Californian. The store I was at had it with up front pricing pushing $9K, but I didn't try to negotiate either. By comparison, a Diplomat or Nautilus would have been between $7,800 and $8,000. I have found no spa forum generally speak ill of Dimension One. From what I've seen, they are in the same class as the other tubs you've named. Wet test several models/brands and select what fits you best at a price you're willing to pay. If you're looking for a lounger, you might check the Caldera Geneva. It has pretty cool foot jets for the lounger. It probably will fall in the mid $8K range also, depending of course on the dealer.
It gets so frustrating listening to people who do not understand how circ pumps work. I'll give you simple explanation....maybe.Circulation pump (Laing 909) is a 8 gpm pump, running at 3450 rpm. That's 11,520 gpm filtered a day. It runs constantly and burns up every 3 - 6 years and causes more heaters to fail than any pump in history. Low flow cause heater corrosion..ask Watkins about having to create special heater just to withstand low flow. Now many use Laing 825 heaters(not titanium) to work with this pump. ? used this for years and realized it was just marketing BS, "cleans 24/7 all year long ...silently." Sounds good, but it doesn't last. Plus it doesn't matter how long a pump filters, it's how MUCH WATER it filters. Take a 56 frame that runs at 1725 rpm and filters 80 gpm or 19,000 gallons per day in only 4 hours. Reminder..half the rpm's and 10 times the flow..3.2 amps for 4 hours a day vs. .95 amps 24 hours a day. It helps to understand. Tri-Zone takes sophistication to understand that it allows you to take total flow of pump and put it to ANY muscle group; shoulders, feet, thighs, low back, total back, calves, hips, knees, etc. No other spa can do that...period. Anyone can produce a spa that runs all the jets full power or half the spa full power. It can be difficult to comprehend because it is so far ahead of its time. Where are you searching (City/Area) for a spa?

Marquis makes it easier to isolate with the zone. However I recently tested a spa where I closed all the seat jets except the shoulder/trap jets and I had an unbelievable amount of power coming from just the 4 trap/shoulder jets. When I was finished, I opened the rest of the jets in the seat and enjoyed a full back massage. You can do what Marquis makes easy in some other spas with another 20 seconds of fiddling with the jets. The difference is you can then open them back up for a whole "area" massage when you're done beating up the isolated area. Nothing against Marquis, but you can achieve the same with other spas just with a different path. I couldn't run with just the four open for more than a few minutes - too intense. I was glad to return to a slightly more relaxed massage after that. I've found it's difficult to sometimes undress sales claims unless you really look around and wet test many models. I think Marquis is a nice spa, but they have their gimmicks just like everyone else. Wet test and make a truly informed decision.
