In many countries, toilet paper is meant to be flushed or people are used to a bidet. For a man, this could mean pretty much no reason to have a trash can near the toilet.
But if you plan on having people over, specially women as a date, have a little trash can with a plastic bag and a lid near your toilet. That’s where your guest might dispose of a tampon, pad, cotton swabs, condom packaging, and similar items.
Make sure you have some toilet paper available even if you prefer a bidet, too - there are many times it could come in handy, and people might be shy to request it after using the toilet and realizing its not there.
I thought this was a given. I have a rubbish bin with a lid and it also functions as a sharps container.
Ye, I’m surprised that many don’t have a bin. Where do they throw away the hygiene/medicine stuff too like used floss, swabs, tissues, completely used products, etc.?
