I'll throw in my $.02 regarding sinks. There's not much need to get them all that wet, most of us use trays, and filling the whole sink with a temperature bath is not very efficient. A decent slope and a squeegee generally gets what little liquid should be in there down the drain. Next, wood and water don't mix. Make your sink out of ABS sheet and you will be much happier. Finally make it nice and tall so your bent arm easily rests on the top when standing, mine is 43" tall and quite comfortable.
