Question: What is the diameter of top opening?
Document: Just that one step that I don't have to do (opening the trash) is a godsend. This was a lot of $ for a trash can but worth it to me. I had a large plant trolley that has the right diameter that I place this on, and I wheel it over to the table when I am doing a lot of chopping. My kitchen trash bags fit it perfectly . 11 Gal.
Once you go with this you will never, ever go back. Ever. It is heavy and holds EVERYTHING...the huge opening at the top makes throwing away anything and everything a breeze. It is unusually tall for trash cans, in my opinion. It looks great in our kitchen and I highly recommend it---and yes, I really am in love with it. You will be, too.
I saw this can in the timeshare I rent every summer. I had to have it. This garbage can works great! The bullet opening keeps the nastiness inside and yet allows easy access to pitch your garbage in. Fast ship and as described item. Thank you.
This one is always clean because it just takes a swipe  with a damp cloth around the top edge if needed. Great! !
Tough to get excited about a garbage can, but this thing is very very nice. I love the open top and it truly is very easy taking out the bags no matter how much garbage you cram in it.
I received this trash can a month ago and I am totally delighted with it compared to my old trash can. The bag stays put and doesn't slide down into the can and the open top is very convenient.
Great can!! I use this as a laundry hamper in the bathroom. It keeps dirty laundry off the floor and holds a lot. The large open top comes in handy to throw laundry into.
We have several of these trash cans throughout our building. They are stylish with the brushed aluminum look. The open top is great so no one has to step on anything or lift anything to deposit the trash. Works great!
It's a very nice trash can. The only complaint I have is for the price I paid, the plastic around the top is WAY too thin and cheap. I give it two years if I'm lucky before it's accidently broken.
The size is great. Big enough to not need changing very often, but small enough to not get in the way. I love the open top design. Never have had any &#34;smelly&#34; issues with it. Ended up buying two of these.
Answer: Large enough for a baby.
