Tub size

I am getting an 08 male normal BP on Tuesday. He will be a year old in July and his current weight is 187.1 grams. I would really like to house him in a tub. What size tub do I need for a snake of his size?

a 16 quart tub would be fine but you could just get a 32 quart to fit it its whole life and give it lots of hides.
