Melamine racks don't go through the break down/reassemble process too well.

I used melamine racks for years.....made all my own. To date, they are among my favorite type of racks. But they are heavy....borderline ridiculous heavy. They don't travel well (as in moving to a new house). Once the open ends of the melamine sheets get wet, they swell. Once they swell, bins get stuck. So be sure to cap them or seal them with the iron-on seam stuff. Melamine is super strong in certain directions but really weak in others. For all those reasons, I have done away with almost all of my melamine racks. Still, you can make an awesome rack out of the stuff if you do it right.....and my ball pythons seemed to love those racks.

Like Satanic mentioned, build your rack around the tubs you decide to work with but don't be afraid to spend a little more on melamine to make two or more smaller racks rather than one big one.
TRUST ME. We took the door size into consideration. It's going to be 2 feet deep.
I know this thing is going to be heavy.. but for my first rack (and this place where I want it is permanent) I can deal with something being heavy.

My carpenter friend says he also has a lot of extra plywood lying around that we could use for dividers and we could also use leftover melamine pieces. :]

I do know that melamine doesn't mix well with water, what is this iron on seam stuff? Where can I get it?
