No you have all kind of 32 quarts out there some will little floor space a lot of height some with proper floor space and lower height however even among those there might be some difference, with 1/2 inch or more difference in the length or width or height.
You want to buy the same brand tub (same model) and get them all at once whether you buy or build a rack, sterile and Rubbermaid for example are known to change there design every so many years, I have an AP rack with sterilite 32 quarts tubs in which their new 32 quarts tubs I use in newer racks do not fit.
Now V70 and all the Vision line tubs remain the same years after yeas since they are specifically designed for reptiles.
