We invite you to a unique wellness experience that combines deep warmth, powerful sensations and delicious winter treats. We begin at 15:30 with an intense Aufguss session in the Kelosauna (nude area). Our sauna master guides you through a ritual of deep heat, rich fragrances and powerful towel movements that awaken every sense. 
The heat opens your pores, stimulates circulation and prepares your body for the ultimate contrast. 
After this invigorating session, we dive into Thermae Grimbergen’s natural swimming pond together. The cool, fresh water delivers an instant energy boost! The perfect way to kick-start a healthy, relaxed and energetic 2026. 
Treat yourself to this wintery experience. No registration required – simply drop by and join in. 


A day of sauna plus a massage for your birthday at a price-busting 61 euros, exclusively for our newsletter subscribers!
