Ill post some pics of my home made rack in a little bit... I just went to Ace hardware and bought a 5 shelf storage rack and you can adjust the heights on each level. I paid 80$ for the rack and it can fit 8 116qt tubs so you should be able to get plenty of tubs on there... I think its ridiculous to pay 300$ for a 4 tub rack when everything is plastic. These ones are heavy duty and you can adjust the size for baby tubs and adult tubs.
