I am in love with this moss bathmat from Yanko Design. Apparently the base of the moss is made from a decay-free foam, which prevents mold. The humidity from your showers and the drops of water you leave when you step out of the bath are all the moss needs to grow.
Only problem is, I can’t figure out how to buy it. Maybe it’s something that would be possible to make? Thoughts? Ideas?
There’s a link to buy it in the comments now, but I was going to say that if you’re seriously interested in trying to make one, I know somebody who might just be able to help you.
