I currently house 1.2 to 1.3 in these tubs:

And it has worked great. However, they take up a lot of height and since I plan on moving them to a unit that is 3ft high, I'd like to change. I see most larger scale breeders use litter pans which are pretty short, will these tubs be suitable?

It is basically the same floorspace, but 6.5" of height. This will also make it much easier and cheaper for me to install food hoppers ontop.

Let me know, Thanks.
