The 28 Best Spas in Belgium for Couples (2026)

In Tournai, there are the Thermes de Kain, which offer a combination of spa, private spa, and hotel. For a pampering day, a romantic night, or a romantic weekend, choose one of the four suites, each with a private sauna and jacuzzi. You can even enjoy a hammam and a heated outdoor pool in the VIP Suite. Another option is Waer Waters near Brussels. The Waer Waters wellness area has a bunch of pools, saunas, jacuzzis, and steam rooms, and is split into three zones.

In general, entry to a spa is around €30-40 per day. This often gives you access to all the facilities, but it doesn't include food, massages and other treatments you might want to book as extras. If you would rather have a private spa, just for the two of you, the rates are around 120€ for 2 hours.

Our selection of the three most beautiful thermal baths in Belgium includes Le Château des Thermes Chaudfontaine, Les Thermes de Kain in Tournai, and Oxygen House Brussels, although the latter is more akin to a private spa.

In Wallonia, there is le Château des Thermes Chaudfontaine, which is very pleasant. Fed by natural mineral water from Chaudfontaine, the thermal baths are equipped with facilities such as: an outdoor thermal bath at 32°C, an indoor thermal water pool, indoor and outdoor jacuzzis, a musical bath, two hammams, three indoor saunas and one outdoor sauna, infrared cabins, salt cabins and even ice cabins, as well as a relaxation room. All the facilities here will ensure you enjoy a magical stay with your partner.

If you want to spend a romantic day at the thermal baths in the Ardennes, we recommend the Thermes de Spa, a very pleasant place to relax and enjoy a wellness day together.

Yes, private thermal baths in Belgium allow you to enjoy all the facilities of the venue exclusively for yourself. One example is Oxygen House Brussels. Located 30 minutes from Brussels, Oxygen House a private and exclusive wellness center offering two villas and one loft that can be rented for the day and/or night. A must for couples, especially when the weather is nice!

For a romantic wellness break in Belgium, we would recommend the luxurious Steigenberger Wiltcher's in Brussels with its luxurious spa area, or Waer Waters near Brussels, a veritable temple of relaxation covering 12,000 m² with numerous relaxation areas and romantic packages.

For example, there is the Butte au Bois in Maastricht, where you can spend the night while enjoying the splendid on-site spa facilities. The hotel offers free access to a state-of-the-art wellness center with a swimming pool, sauna, and jacuzzi. Facials and massages are also available.
