When we remodeled our kitchen nine years ago, the two (2!) things I asked for were a trash can under the sink and a tip-out in front. I got the first one, but whoever measured for the countertop cut-out did not allow enough room for the plastic thing that goes inside the tip-out. It's just about 1/4 inch too narrow. When we have the new countertops done, we are going to make sure they allow room for this. I don't think having the sink a half inch, or even an inch, farther back will make any functional difference. Speaking of this, where do you get the piece that goes inside? What exactly is it called? The one we have (that's been sitting under the sink for nine years) is really small. It would be nice to have one that goes the length of the tip-out.

I bought SS holders that have 2 suction cups to attach them to the side of the sink at Target. I only keep a scrubby in mine b/c I use dishcloths instead of sponges. The scrubby in the cleanup sink is for dishes, the one in the prep sink is for lightly cleaning veggies like potatoes & carrots. Here's a pic of the prep sink w/a green scrubby: The scrubby dries quickly in this setup b/c it's in the open & exposed to clean, dry air. IMHO, there's less likely to be an explosion of bacteria growth b/c of this. (I still sanitize it though, just to be safe!)

I personally wouldn't want to use wire because everything I put in mine is wet. Wet things lead to drips down inside the rest of the cabinet. Mine tip-out trays are plastic. Yes they get dirty and grubby but I just pop them out and clean them now and then. Everything needs a little TLC and maintenance that is worth having, right? I had a wire basket thingy that held a pump hand soap bottle. I finally got rid of it because it was a lot of trouble just to keep it up because it 'looked good' by the sink. I still had to clean the gunk off it all the time. I would imagine the wire sink tray would be the same. My $.02.

I'm confused - how do you have a sink without counters? Assuming your sink is undermount, will the section of counter in front of the sink really be so narrow? Mine is 3.5", only about .5" of which overhangs the cabinet door fronts. I thought that everything that could go wrong or be mis-measured in my kitchen was, but this wasn't. But now I understand why my GC didn't include tilt outs from the beginning when I thought they were standard and easy. I guess sometimes they aren't.
