Hi Melnee, this is a custom made Glenwood cabinet. We are unsure of anywhere that you might be able to purchase something similar off the shelf in a retail store. If you contact your local cabinet maker I'm sure they would be happy to help build you something like this.

to be honest I don't understand how this copuld be practical? Isn't more practical tu just make one deep drawer so you can put the trash can also?

HI Oara, most of our kitchens have a separate pull out waste bins, so there is no need for a trash can under the sink. We have found our customers enjoy this feature as it makes it easier to access the cleaning supplies that are inevitably stored in the sink cabinet. They no longer have to get down on their knees and reach under and back, they simply pull this out, grab what they need from the top, and push it back in with a toe. It's been very helpful for those with mobility and movement issues.
