I need help with a tub

I just got a stiralite tub and I am going to be switching my snake to it. I was wondering how should I drill holes in it? And can I just use my solder iron and just burnbit through there to make holes?

I use a sodering iron. Be sure to poke from the inside out so that the rough edges are on the outside of the tub. Make sure there are no sharp edges poking in for the snake to rub.
