This is how it works in my house:
There are three bathrooms. I live alone. None of the bathrooms has a bin. I don’t use cotton pads/wipes regularly but when I do I leave them at the side of the sink (if it’s nighttime) and carry them to the kitchen bin next morning. If I use them in the morning, I carry them to the kitchen bin when I’m going to the kitchen.
Guests use the guest bathroom and can do the same, and indeed they do dispose of them similarly to me.
No drama, no fuss, no disgust, no towering piles of dirty rubbish.
Yeah, I've stayed in houses with no bathroom bin, and felt compelled to hoard my rubbish before moving it on in the morning. I, of course, didn't pass comment, but I did find it rather bizarre and inconvenient. I wouldn't fuss, even though I'd think it was a pain in the arse.
Guests doing what you do isn't complicit agreement to your method; it's forced on them. Suggesting they are totally happy with it, purely because they don't pass comment, is disingenuous.
