That is actually a hot tub made by Strong Spas . You can look them up to find out more about the construction and details . The tub you are looking at is actually a Strong "Summit" series version . Its a Strong SL60 (with a lot more jets) .
Strong Spas
I have noticed that Strong markets heavily to to big box stores , besides using there own name brand products for retail sales .
They have base tub molds, and produce differing hot tub models for box stores and the likes . Spa Depot also carries a version of Strong tubs . Spa Depot "Belize" UVC-900-L is the same mold you are looking at (with less jets) -
Belize . Usually the differences are in the amount of jets , cabinet designs , and sometimes pump differences , but the main shells are all the same . Strangely , the versions marketed to the box stores and un-labeled (no defining "Strong Spas" badging) retailers, are the models with the largest amount of jets , and seem to be the best value . Strange.
I live about 5 minutes away from the Strong retail "Flagship Store" , and literally 15 minutes away from the Strong manufacturing facility.
We have an older 400 gallon Coleman tub (that we love) , but have recently thinking about upgrading . We were very impressed with the Strong tubs, and it would likely be at the top of our list if we purchase a new tub . For us, the choice to go with a Strong is a little easier as the factory is basically in the same town , so warranty would not be an issue .
Do some digging, and see what you think of Strong Spas , because that is the brand of Tub you are looking at !
