Either Energysavers in Meredith or Stargaze in Laconia would maybe do that.
There is a hot tub called spa-n-a-box which comes in about five sizes, all inflatable, and constructed somewhat like a Zodiac inflatable boat.
www.spa-n-a-box.com One of its' advantages is that it is more easy to transport, like out to an island or to an ice fishing bob house w/ a long extension cord plus they are less expensive.
Does anyone have any experience with one of these spa-n-a-box hot tubs? Are they any good or what?
