Welcome to our forum.
IMO, Marquis makes the best line of smaller 110 spas available out there today but, hey, that's just my opinion!
I have room for a hot tub that is about 5 X 7 I would like a few jets especailly for my husbands back. I only have regular plug ins. I am worried if the hot tub can heat itself on the 110 plug in. I like water to be 104 degrees. Thank you for the help so far I have been looking at the hot tubs you mentioned so far. Thank you sooo much. Debbie
