I have not seen sink grids before - is this what you mean? If it was 1 inch too small all around, i think it would shuffle a bit but it is unlikely you would notice it much. And if it didn't have some gap, it would scrape as you took it in and out. Hope this helps!

Different strokes for different folks, as they say. We have a butlers pantry, smallish, with a sink in it. The pantry has become effectively a walk-in pantry, with storage, a wine fridge and the toaster and microwave. It's very useful, but we almost never use the sink because there isn't enough practical counterspace and because, well, who wants to do dishes in a closet? We also have an island, with a single basin sink in it, and of course the dishwasher. That's where we do prep, and it works just fine for us. We can watch TV while pealing spuds or washing those dishes that don't go into the dishwasher. Even with the sink, there's still plenty of prep space, and we have a good work triangle between sink, oven on the wall directly behind it, and fridge, oven and pantry on the end wall. In practical terms, the arrangement works for us. When we entertain, we clean up and load the dishwasher as we go, dump the pots and pans in the butler's pantry, wipe off the bench, and we're good to go. And since it's only a single basin undermount sink, the look is clean enough for us.

Hmm, 200mm diameter is about the size of a side plate, 300mm dinner plate and after a quick look at a few sink brands (eg Clark they seem to all be closer to 400mm). I did comea Cross this one but have no idea of the brand quality http://www.swanstreet.com.au/CM1-Undermount-Single-Bowl-6L-Small-Bar-Sink-330-x-200-x-125mm~3600

Does anyone have any feedback on these sinks? Preference on brand? So many mixed reviews online.
