I am looking at getting this sink.

http://www.irawoods.com/DecoLav-1425...category=48094

it does not have an overflow hole.

Will this cause a problem with slow draining as I have been reading or is this remediable with some other parts installed ?
I am also looking for a specific type of faucet, is there any requirement for specific type of faucet for a vessel sink ?
will this work ?
