pirateroo Wolf only does this size, they have several units, all are 15" designed to stand alone or be installed side by side with a filler strip. It comes with a solid pan and a perforated pan so you can cook different foods at the same time.. It can be used to boil pasta, steam, reheat or keep food warm, poach foods and can also be used as a slow cooker. It has an electronic drain as well. I am putting mine near my cook top which allows the pot filler to make it a prep sink as well. All in all a very versatile addition to the kitchen! Gaggeneau also does an in-counter steamer as well.
