As any other room used for the medical purposes, salt room has to comply with high hygiene standards. The major obstacle in this type of rooms is that there are salt particles in the air that eventually settle on surfaces and therefore additional clearness measures have to be taken.

First of all, the salt room has to be properly isolated from the other premises. A salt room is often a part of SPA or clinic. Salt particles easily pass through the door if it is not properly constructed. As a result staff or visitors of SPA/clinic have “passive salt-therapy” that in some cases may be not beneficial but rather harmful. Thus, salt room has to be appropriately isolated. 

Tip 1: To isolate a salt room from adjacent premises use a tight or double doors. Consult the ventilation or air conditioning adviser.


Quite often salt rooms are overcrowded, that should be avoided. 

Tip 2: For each patient at least 8m3 of personalized space should be provided as primary “infection control measure”.


It is known that salt is a potent bactericidal agent. The amount of harmful micro organisms in the air of a salt chamber is less than in normal conditions. This is proved by the example of salt caves, which have been used successfully for treating many diseases for hundreds of years. Salt room, simulating the healing atmosphere of the salt caves, usually has a coat of salt on its surfaces.

Thousands of tons of salt in caves is incomparable to decorative coat of salt on chamber walls.

The walls and ceiling are covered with wet salt sand, which while drying creates a lasting finish. If the salt contains anti-caking agent (as table salt normally does eg, E535, E536), then special glue is added. Floor covered with a thick layer of coarse salt. Sometime natural salt blocks are used.

The therapeutic effect is achieved only by the salt spray produced by a salt generator. Salt therapy works equally well in a room without a salt coating.

Over the years of use salt due to its properties absorbs substances exhaled or brought by visitors, it also absorbs dirt from outdoor. Furthermore, visitors unintentionally can bring allergens from their homes or outdoors to the salt room. In time the surface looses its pleasant view and becomes unattractively grey. 

The floor can withstand thousands of visitors. However, even following the hygiene rules dirt mixes with the salt on the floor. Children usually play with salt like if it would have been the sand in the sandbox. Such behaviour often encourages owners of a salt room to make special places for kids to play. Over time, salt become a caked mass and changes its colour.

Allergens are not destroyed by the salt and eventually, the concentration of for instance house dust mite, cat or pollen allergens will increase in the floor salt that can be unsafe for the sensitive/allergic persons. Thus, polluted salt on the floor could be extremely harmful. Importantly, the therapeutic effect in salt rooms is achieved only by the salt aerosol produced by a salt generator, but not by the decorative salt covers.

Tip 3: Clean surface is preferable in order to have access to washing the surfaces of a salt chamber. Wet cleaning of the floor and chairs/armchairs/beds should be done on everyday basis. When using salt coatings - update them annually. Never use salt on the floor. Avoid situations in which customers may freely contact salt coating. Contact CURENTEC for advice!


Ventilation is an important part of a salt room. With the proper ventilation the comfort of visitors can be greatly improved. Salt rooms may be located in countries with hot climate. In such cases air conditioning system is vital. Salt generator CURENTEC can freely operate with continuously working ventilation or air conditioning system.

Tip 4: Pay special attention to ventilation. Use the salt generator CURENTEC and install it properly in the air flow. Fresh air is an important part of successful treatment.
