Our tubs are really not that much different in size Robin... The only real difference is the height. I like to provide my snakes with something to climb on so my tubs need to be taller... When you add the height you add many more quarts. The measurements of the 60qt i just bought is 22.8x16.7x13.6... Again mine need to be just a tad bit longer bc the climbing thing I add takes up more space. Once you put in 2 hides(zilla small baby hides), a decent sized water bowl(all mine are the same kind from target pet department), and the climbing thing (some fish decoration from pet co that is perfect for snakes) theres really not much room to stress the snake out. The pictures I took show every step I took to putting the tub together and I think are sticky worth... I guarantee my set ups will never "stress" a snake out due to the size being too big... My yearlings get 96qt tubs only bc the hides need to be bigger, take up more space, and dont fit in the 60qt... well I cant say they wont fit bc they will it just eliminates almost all the floor space. 96qt just gives you the floow space back.
