Looking for recommendations on nappy bins. It's for my FIL who has urinary incontinence as his disposable underwear is getting a bit out of control smell and mess wise so I thought a specific bin would be nice.

We would need one that is preferably on the large side and that holds in smell really well. Currently looking at the Korbell bin or the Ubbi bin. The Ubbi, while more expensive, is edging forward for me as it doesn't take specific bags.

Thanks!
