From all the posts on here I came up with this. It is very simple and was very cheap to build but it is very sturdy and will work for years to come. I have the flexwatt on the way as well as a thermostat and tubs. It is for 32 quart tubs and will hold 9 of them. I planned on ten tubs but that takes another shelf and a sheet of plywood can only make 10 of the shelves (I forgot about the top lid shelf). Also if I would have added the last shelf my girlfriend wouldn't have been able to see in. LOL

I know the tubs are going to need ventilation holes in the side. I got this idea off the plan that is on here that has the red background, so I am going to make the holes the same way he did on there.

I built this in the living room of my 1 bedroom apartment. I had the plywood cut by lowes and used a hand saw to cut the 1X2 and the 1X4.

Oh well let me know what you think and if you have any questions.
