Sauna Ice

Menthol crystals open your airways, cool your skin, and make the heat hit differently. Drop a few in warm water, throw it on the stones, and your sauna becomes something else entirely.

Sauna Ice is 100% natural menthol crystals from North Shore Sauna. One bag lasts roughly 140 sessions — more if you're measured about it, fewer if you're not.

• Use: Dissolve 3–5 small crystals in a bucket of warm water, then ladle onto the stones
• Yield: ~140 sessions per bag
• Ingredients: 100% natural menthol crystals
• Storage: Keep out of the sauna — it will melt in the heat and humidity
• Caution: Avoid contact with eyes and sensitive areas; consult a physician if you're allergic to menthol or pregnant
• Brand: North Shore Sauna
