There are over 100 spa manufacturers with over 1,000 different models of hot tub in the current market BUT, and this is the good news, 75% of all spas use only 20 different covers.

Radius: is the opposite you need to go smaller. An 11” radius can be covered by 9” and a 7” radius can be covered by 5”.
