The problem I have seen is with the child sized lockers is that they tend to not be tall enough for hanging things like snowpants and especially if boots are put in there too.

Mostly it is my parents that dress and undress the kids due to age and therefore do the hanging up. I have a bench that has a back on it and hooks. Boots go on a boot mat near the door.

One of the things I did in a previous house which worked really well because my own kids were school age and I had a couple of school age daycare too. I got a utility cabinet from home depot - it has shelves on the one side and is full on the other - where you would stand brooms or ironing board I guess. Anyways hubby installed hooks on that side and then coats went there and they each had a shelf on the other side for back packs, or diaper bags and changes of stuff. I had room for three of them which also allowed me to stow away all of the family gear in terms of sports - ie rollerblades and helmets too for my own kids. New house is laid out differently at front door hence the bench system and I have one cabinet with full shelves where I have bins for each child in it for changes of clothes, shoes etc.

I guess my point is take a look at the full size of the lockers in terms of usable space before buying as the coat area is small if there is storage at the bottom and often the kids still need to climb onto the bottom to hang stuff up. If you don't want them doing that then replacing the hooks on the wall might be a way to go and getting one of the plastic drawer systems for storage.
