The lagoon itself is a man-made construction, its bottom is covered by sand and gravel. The characteristics of the water are unique in many ways. It contains a large amount of minerals, is alkaline and well suited for bathing. Due to its chemical composition, undesired bacteria and vegetation do not thrive in the lagoon making chloride or any other disinfectant redundant.
Geothermal water in Iceland usually contains some sulfur. In this area the strength of the chemical is greater than others. Therefore is should be avoided to take jewelry from brass or silver into the water, they become black and can be damaged. Sulphur, however, is considered to have a positive effect on asthma and other respiratory diseases, and many of the trace elements in the water are considered to have a good effect on the development of skin problems.
The two steam baths are built straight on top of a geothermal area and the sulphurfree steam rises up through holes in the floor.
Typically the temperature is around 50°C and the humidity is close to 100%.
Guests can take a few turns in the steam baths and cool down in the outdoor shower in between.
The changing rooms can accommodate upto 300 guests at a time. You may put your belongings into a locker or leave your valuables in a safe in the reception. All guests are asked to wash thoroughly and take a shower before entering the lagoon.
