I had one in my previous house, but didn't in my current. I made sure it was added in my remodel. The "standard" ones were too deep, so my cabinet maker installed the narrower profile ones. I have a 36" sink base. On one side is where I keep a supply of Finish tablets for the DW (the bulk box from Costco is too mig for under the sink). The other side is used to store some cloth wipes, milk bottle caps and the drain stopper. I don't put anything wet in there. The sponge just sits on the sink grid where it can air dry.

> Where can you buy these things? Lowes stocks them. I always use these. One tip - install the hinges and have your countertop, sink, and the lower doors of the cabinet in place before installing the tray(s) themselves. And then position the trays as low as possble without hitting a cabinet frame support underneath. That way you'll get the most usuable room inside - room to store small sponges on their side for example, and more likelihood things will fit in the first place. My last installer placed them too high, and besides limiting the available height of items placed in the tray, also the top of the cabinet front won't quite close all the wall because the top of the tray sides scrapes the countertop support that frames the top front of the cabinet. I'm going to need to lower the tray about an inch. For the neatest installation, install the cabinet pull(s) first and counter-sink the screw, then uses screws to hold the tray onto the inside of the door afterward, usually covering the cabinet pull screw(s). Dont drill a hole through the tilt-out tray to mount the knobs or handles - it doesn't look good from inside and precludes adjusting the position of the tray if necessary.

I opted not to put them in as it can affect front-to-back clearance of sink and fixtures. The sink has to be sure to clear the tilt-out-tray and since I was not doing a bump-out, having sufficient room for fixture clearances was more impt. That said, I probably could've squeezed it in--but wanted to be safe. I have a suction cup wire holder on the side of my sink for the sponge and feel it airs out better there, plus as said above, I'm not always grabbing the sink hardware with drippy hands. I don't really miss it. I had before and stored a toothbrush and stopper there, but they were always falling down when I opened it up so for these things, I keep a little basket in sink down below.

Personally I don't understand how anyone uses these work station sinks to do any serious chopping/cutting. Ergonomically they seem wrong. The cutting board goes in the wrong direction for me. When the sink is under mounted the cutting board sits lower then the countertop. When anything falls off the cutting board it is dropping into a dirty sink. Also when you want to use the sink to wash anything then you have to remove all the parts. The colander on these types of sinks looks tiny. No way a full pot of pasta can be drained in it.
