I was worried these would be overwhelmingly powerful, as eucalyptus often is, so I broke off a little chunk to test it out. It was actually so subtle that I put the rest of the steamer in and it was really enjoyable! It’s not powerful like a steam shower at a spa but it’s just enough to last through a long, hot, shower and make taking deep breaths easier. I’ve only used one so far and I had a little trouble getting it to melt slowly without completely washing down the drain but I think if you have a tub it would work better on a shelf near the faucets, so it can get a little steam and splashes of water without dissolving too fast.
