Commercial Refrigerator for Family Use?

I've only got 2 kids but on most days, our fridge is just about ready to explode. In fact, there are times I don't complete all the grocery shopping in one go because I know that the perishables will never fit in our fridge. It seems like no matter how I try to organize the fridge, there's just not enough space!
I am thinking whether it makes sense to trade our regular-sized fridge in for a commercial refrigerator. They're built to last and will have all the space we will need, and then some! It may sound overboard, but in a few years, the kids will be in their teens and will probably be wolfing down food, not to mention regularly bring over friends home. I just can't imagine our current fridge holding up to that kind of demand, it is probably a good idea to invest on a commercial fridge now.
