I’m not here today to debate the need for having a garbage can in your bathroom, but I will simply put out the facts and share what I’ve also found from others.
I personally have never really found a need for trash can in the bathroom. I don’t really have much waste and try to use more environmentally friendly means. I found this post by treehugger. which pretty much sums up my reasoning for not having a trash can.
At the same time, I understand that not everyone may use the same logic as me, and so for those, I will put a trash can in the bathroom.
As for your bathroom and whether or not you need a garbage can, well that’s for you to decide!
