I've been making herb infused water to pour over the rocks for a bit of aromatherapy, that's been a great sauna addition for me.

- Get a bunch of fresh herbs (I'm sure dried could work too)

- Pour boiling water over it

- Let it sit covered for 15-20 mins

- Strain well (really, it was not a pleasant smell for chunks of herbs I did not strain out to burn on the rocks)

- Pour over rocks and enjoy 😌😌😌

So far I've tried combinations of lavender, rosemary and mint
