A drain can be your best friend.....or your worst enemy. When you have a spill, and you will if you do this long enough, you want to think containment.
If you have a drain but the thing is plumbed into a drain system, it's an invitation to a loss. (Both financially and environmentally!) If it sits over a bucket or a drum, still a potential for a loss. You know, when you need the bucket for something else just when you have a spill.
I like a drain but I also like to know anything spilled is contained.
One option if you want to have the drain is to have it flush in the bottom and have a 2" stand pipe which you can remove if you wash down the hood but use it when operating. It prevents any spills from flowing down the drain, (into the bucket) until they are deeper than the volume of the base of your hood and 2" deep. A 4 foot by 3 foot by 2" deep catch is just shy of 15 gallons. If you have a spill that big you should consider taking up knitting!
I would also offset the drain so it is not right where you are working, especially if you go with a stub up which will be sticking up 2".
