Salt cave or salt room?

A salt cave is a natural underground space in rock salt. A salt room is a built interior that recreates its atmosphere above ground.

Natural salt caves

Natural salt mines and caves have a stable temperature and humidity. Visiting them is known as speleotherapy and depends on travelling to the location.

Salt rooms and salt caves above ground

A built salt room or salt grotto brings the look and atmosphere into a spa, hotel or home. Decorative elements such as salt stalactites, salt walls and lighting can make it look like a real cave.

Why the halogenerator matters

The difference between a decorated room and a halotherapy room is the halogenerator, which adds the fine dry salt aerosol in a controlled concentration.

Planning your own

We design and build salt rooms and salt caves in 4–5 working days and match the halogenerator to the room size.
