Naturally Carbonated Mineral Baths of Marienbad

What is a naturally carbonated mineral bath

This is a signature treatment, exclusively provided in the spa resort of Marienbad using the naturally carbonated mineral waters that spring out from the ground locally. The mineral water with dissolved gaseous CO2 is heated to temperatures between 32-34°C to preserve as much CO2 as possible and to ensure acceptable bath temperatures. After heating, the mineral water flows into an individual bathtub. The carbon dioxide fizzes onto the skin, producing a relaxing, tickling sensation and a reddening of the submerged skin. The bath is followed by a relaxing dry wrap, to ensure maximum benefit from the treatment.


How a naturally carbonated mineral bath helps

The gas is absorbed through the skin into the body, where it widens the blood capillaries, thus reducing blood pressure and improving heart pump function. It also suppresses feelings of pain and cold, so after a while you will feel warm in the bath despite a relative perception of cold at the beginning. Several treatments will result in more efficient blood circulation all over your body, improving the function of all your inner organs (including the heart, kidneys and reproductive organs) as well as reducing stiffness and pain in the muscles and joints. Moreover, the carbonated bath relieves stress and anxiety.

More information about treatment including indications and contraindications

If heated above 35°C, the gaseous CO2 evaporates and its healing effect is lost, therefore we do not oblige any request to increase the temperature of the carbonated baths. In case you have a pacemaker or defibrillator, moderate heart failure or moderate breathing difficulties, you are advised to take only a half-bath (with the water reaching heart-level at a maximum) not to overload your cardiorespiratory system and to avoid the worsening of your condition. The pressure of water on your chest may be hardly tolerable in such cases.

The carbonated mineral bath is suitable for children as well. In such a case, it should be prescribed by a doctor, with the water level taking into account their age (min. 4 years) and height.

Advisable for:

Musculoskeletal diseases, orthopaedic and accident rehabilitation, stress, fatigue, kidney and urinary tract disorders, metabolic and cardiovascular diseases, certain diseases of the respiratory tract, certain skin diseases, infertility and gynaecological problems, neurological diseases, convalescence after oncological treatment

Not advisable for:

Infectious diseases, fever, acute inflammation, unstable chest angina, severe heart failure, severe shortness of breath, epilepsy, acute thrombosis, phlebitis, leg ulcers and other skin defects, incontinence, psychosis, alcohol or drug abuse, menstruation, incapacitation

Treatment at a glance

Naturally Carbonated Mineral Baths

  • What it is

    A 15-20 minute soak in naturally CO₂-rich mineral water, kept deliberately cool (around 32-34°C) so the carbon dioxide stays dissolved. Fine bubbles settle on the skin and are gradually absorbed, gently widening the small surface blood vessels.

  • Who it's for

    Often suggested for guests with mild high blood pressure, sluggish peripheral circulation, or those in stable, supervised cardiac rehabilitation. Every course is prescribed by our resident spa physician after your entry medical examination.

  • Expected results

    Guests typically describe warmer hands and feet, a gentle easing of blood pressure and a characteristic skin-tingling “champagne” sensation. Benefits tend to build gradually over a course of roughly 6-12 baths across a healing stay.
