Thermae Grimbergen, an oasis of peace and quiet in the green outskirts of Brussels

Thermae Grimbergen is a unique wellness centre with over 20 years of experience. Over the years, the thermal baths have been regularly renewed and a couple of years ago a beautiful green domain was added. The sauna complex consists of two parts: Aquarius is our naked section, and Sabai is for those who prefer to relax in swimwear. Complete your day of wellness with a heavenly massage or blissful facial treatment, or spend the night at our wellness hotel.

Did you know, by the way, that our hotel guests can enjoy our sauna and wellness facilities at a great discount? When you spend the night at the Thermae Grimbergen Hotel, you can take advantage of a reduced price on the day of arrival: an impressive 50% saving on the entrance fee to the public baths after 17:00!

* The student rate (16,45 euros) is only valid for fulltime studentes aged between 12 and 25 on Tuesdays, Wednesdays and Thursdays. Only valid by showing a valid student card for 18 - 25 year olds. Not available on public holidays and during school holidays (Autumn break, Christmas holidays, February half term and Easter Holidays). Available during Summer holidays.

** Children are allowed in our centre from 6 years onward. They have to respect the serenity of the centre and are permanently under the responsibility of their parents. We will ask you to sign an agreement upon your arrival.
