Double Pot

I want to buy a large pot (5 gal? 7 gal?) To boil lots of water (brewing beer house) that is made to fit on two burners. Thus, instead of being round, it would be ideal if it has an oval or something similar. Is something like this exist? If not is there a good reason why all the pots are round?

I know you can get metal "washbins" which are generally used to put ice and bottles of beer / soda, by the parties. Maybe it would work? ..... Try Hobby Lobby, and there where they sell party supplies patio or .......( They are exactly the size you want)

They used to make a copper pot of double size, sort of oval wooden handles, people used to canned food. Try an older hardware or antique store.

The only thing I can think as far as why pots are round is for even cooking.
