I have a very old Jacuzzi Sport that I had purchased second hand years ago that is 110 (but can be wired 220.) It has run like a champ outdoors in snow all its life. The sport line, circa mid 90s, has the bench formed seating, plastic bottom well with cedar skirt. I tell you this because this old style periodically turns up on craigslist and often just needs a tune up (eg pressure switch, etc., that would be cheap...whereas pump is not.)
Last year, I did have to replace the 17-year-old pump. The repair guy figured it was worth it because it was in such good shape otherwise.
A few notes about running a smaller-style/portable hottub outdoors in winter -- first is water access in winter, because if you use it a lot, you will need to top it up now and then due to evaporation, carry out and whatnot. My outdoor faucets are closed during the winter, but since the hottub is near a second garage with running water, I keep a hose stored somewhere "warm" to keep it flexible and then top up by attaching it to the utility sink in the heated garage and running same out to the hottub.
The second note is to be sure to cheek the tub anytime there's a "gfi" event like a storm, brownout, heavy ice rain, etc. Mine will come back on but in "Econ" mode which means no heat...so you have to set it back to standard.
Third pointer is to religiously clear the snow off the lid to avoid difficulties or cause cover sag -- and to be sure the cover is rated for winter....snow rated covers are thicker and are designed for the load. My old hottub (a vita spa duet) was the oval type with a normal cover and not only did it sag from snow, it was also extremely difficult to manouever in winter because it was not the creased type.
Good luck in your search! I love mine, and use it every single day in the fall, winter and spring...and more than you might think in the summer too! What a great gift
