Hi, annkathryn. I'm interested in the smaller 33" Stages and had the same question about mounting over a dishwasher. The answer is probably not if you're using stock cabinets, and probably if you're doing custom. The spec sheet says you need 3" on all sides for the mounting brackets, so that would require a minimum 49" sink base. You could theoretically mount it on top of your dishwasher, but the drainboard is 1"13/16 deep, so unless your countertop is 2" thick, you'll need your base cabs to be a bit higher than normal for a full-sized DW to fit underneath. There was another GW thread about this a while ago: http://ths.gardenweb.com/forums/load/kitchbath/msg0521412826100.html

Thanks Mizinformation, that was helpful. Are you thinking of the 33" sink for your main sink or for prep? Is it big enough to be the only sink in the kitchen?

I've had my Kohler 45 in for almost 2 years! Love it. My cabinet maker did some modifications -- my garbage is under the shallow end of the sink. Don't know if you could fit a DW under that end, tho, without raising the cabinet itself. Here's a link to the review that I did that shows the cabinet.

Ours will be a beverage/prep sink. Bowl size is around 20x18, which is what I want, but my Dear Partner can't live without his double-bowl 36" sink for dishes. Check out rjr's review -- you can see that the Stages has a bracket on the underside of the drainboard (where you can mount an optional pull-out accessory rack in the cab below), which is another inch or so. You can see in the photos how rjr modified the cabinet drawer to accommodate the bracket. And forget what I said about the countertop (duh): the Stages is undermount, so the drainboard will be nearly 2 inches lower than the bottom of your counter, plus the inch or so for that bracket, so you'll need a 38"+ high cabinet to get a normal DW under there. Even if you could remove the bracket, that means you're looking at cabinets at least 2" higher than normal. I'm actually putting my prep sink in a 40" tall bar/peninsula, but everyone in my family is freakishly tall. Good luck!

My 33" stages is going in the island as a prep sink. The cabinet under the shallow part will be my trash can pullout, and above it a small drawer for knives. I am having custom cabinets made. I will be giving the cabinetmaker the sink so he can make sure it all works.

Look at Buckheadhillbilly's kitchen pics for some photos. I've posted a link to a discussion about this sink. Scroll down and you will see photos of the cabinet under the sink in this kitchen
