A day in the sauna is ideal for complete relaxation, even during the summer months. The combination of warmth, rest, and fresh outdoor air helps your body and mind recharge fully. Starting your sauna visit well prepared ensures a carefree and truly enjoyable experience.
That’s the first question, and at Thermae Grimbergen, it can be both, so the choice is yours!
Our public thermal baths are divided into a swimwear section and a nude section. You’re welcome to use both, as long as you respect the dress code. In the swimwear section, wear tight, short swim shorts, a fitted swimsuit, or a bikini. Loose swim shorts, thongs, swim dresses, and burkinis are not allowed.
In the sauna, it’s important to sit or lie with your whole body on a towel. From your head to your feet on the towel.
A second towel is essential for drying off before getting dressed again. Especially in summer, an extra-large towel is handy for relaxing on a lounger in our garden. To walk around the thermal baths, it’s best to wear a bathrobe and non-slip slippers. Want to make things easy? Simply hire a bathrobe, towel and slippers from reception when you check in, no need to pack them at home!
On a summer sauna day, we naturally hope for sunshine so you can enjoy our beautiful green wellness domain to the fullest. But don’t forget to protect yourself! Bring sunscreen, sunglasses, and maybe a sun hat to stay safe in the sun.
A sauna day is the perfect time to finally dive into that fascinating article or good book. Reading quietly is the ideal complement to your wellness experience!
You’ll find shower gel and shampoo in our showers, but you might prefer to use your own. So don’t forget to pack them! Also pop a brush or comb in your sauna bag so you can style your hair before heading home.
And we love finishing off a wellness day with a nourishing body lotion or cream to keep our skin soft and supple.
