Rauha™ Stone Sauna Aromatherapy Cup

The Rauha Cup is a controlled way to scent your sauna. It sits among the heater stones, holds water and a few drops of essential oil in a stainless insert, and releases aromatic steam slowly as the cabin heats. A vessel, not a device.

Pouring neat essential oil straight onto hot stones can flare and gives a sharp, fleeting hit. The Cup dilutes the oil in water and warms it gradually, so the scent builds as steady aromatic steam instead of a harsh burst. Slower, cleaner, more controlled.

It sits among the heater stones, nestled near the top so the cabin heat warms it through. You fill the stainless insert before your session and let the rising temperature do the work. No mounting and no hardware, you just place it among the stones.

Water plus a few drops of sauna-safe essential oil is the standard fill. You can also dissolve a small amount of menthol crystals for a brisk, minty löyly, or use plain water for humidity alone. The water carries the scent, so never add neat oil on its own.

A few drops into the water is plenty. Essential oils are concentrated, so start light and add more next session if you want it stronger. Too much oil reads as harsh rather than refined, and a small amount carries well once the steam starts to rise.

Top it up when the water runs low or the scent fades, which usually happens within a session as the heat evaporates the water. Keep a little water in the insert so the oil always has something to ride on, and empty it once you finish.

Gentler and more even. Instead of one sharp aromatic blast, the Cup releases a steady scented vapor that holds through the session. The air feels fresh and lifted rather than suddenly intense. It is the difference between a splash and a slow build.

A solid soapstone body with a removable food-grade stainless steel insert. Soapstone is dense and heat-stable, the same kind of stone long used in sauna stoves, so it sits among the heater stones without warping. The stainless insert holds the water and oil and lifts out for cleaning.

No, because the oil never touches the soapstone. The water and oil sit in the removable stainless steel insert, so the stone body stays clean and does not take on scent or oil marks the way a bare soapstone dish would. You clean the insert, not the stone.

Soapstone is built for this. It is dense and heat-stable, which is exactly why it is used in sauna stoves, so normal sauna heat will not harm it. It is a soft stone though, so avoid dropping it or shocking hot stone with sudden cold water.

It is the large size in the Rauha range, sized to sit among heater stones and hold enough water for a full session. Exact capacity and outer dimensions: 2.75x3" and 2.5oz.

Yes. Dissolve a small amount of menthol crystals in the water in the insert for a brisk, cooling, minty steam. Crystals and essential oils both work the same way here, the water carries them up as vapor. Start with a little, since menthol reads strong fast.

Lift out the stainless insert, empty it after each session, rinse, and let it dry. Because the oil lives in the insert and not the stone, switching from one scent to the next is easy. Rinse the insert and you are starting clean. Do not leave oil sitting between sessions.

No. The Cup needs hot stones to sit among and heat it, so it is made for traditional wood-burning, electric stone-heated, and hybrid saunas. A pure infrared cabin has no stones and no steam source, so there is nothing to warm the water and carry the scent.
