Well... apparently Canadians love their tubs too!
I've been told that my little city of London Ontario (aprox 400K people) has one of the highest per-capita concentrations of hot tub dealers in all of North America.
In no particular order, I had these to choose from within a 50 KM radius:
Arctic
Beachcomber
Caldera
Cal-Spa
Coast Spas
Coleman
Catalina
Hot Springs
MAXX
Pacific
Emerald
Dynasty
D-1
L.A. Spa
Sundance
Sunrise
Hydropool
Hydro-Spa
Marquis
Master Spa
Can Spa
Gulf Coast
Jacuzzi
Great Lakes Spa
Royal Spa
Bullfrog
Viking
...and at least a half-dozen off-brands that I can't remember right now.
It was only with a lot of research and tons of helpful insight from this forum that I was able to narrow down the list for wet-testing. So...um, THANKS!
