Hotel - Thermen 't Mineraal
A nude thermal spa with indoor and outdoor pools
About this hotel
Hotel - Thermen 't Mineraal is built entirely around its nude thermal spa, with both indoor and outdoor pools set in a rural location nine minutes' walk from Rijmenam's Jachthoornlaan. The restaurant and bar serve a relaxed stay rather than a family-activity one, and free breakfast, free parking and kitchen access are all bundled in. This is a genuinely different format from a conventional hotel pool: the nude-spa setup is aimed at adults seeking a dedicated wellness break, not families combining it directly with a children's water park day. It sits a longer drive from Plopsaqua than the old-town hotels, so it works best as its own destination with the water park treated as a separate outing.

This is a niche pick, an adults-focused nude thermal spa hotel with real indoor and outdoor pools, best suited to a couple or group of adults wanting a dedicated wellness stay near Mechelen rather than families combining it directly with Plopsaqua. It's worth confirming the format suits your group before booking.
- ✓Confirm the nude-spa format works for your group before booking, since it's a different experience from a standard hotel pool.
- ✓Treat Plopsaqua as a separate day trip if you're staying here, given the distance and the adults-focused setup.
- ✓Use the free parking and kitchen if pairing this with a longer, self-catered Belgian stay.

Why guests love itThis one is really for the adults in the group: a nude thermal spa with proper indoor and outdoor pools, free breakfast and parking, set in a genuinely rural spot near Rijmenam. We treated Plopsaqua as a separate day out entirely, since the drive from here isn't short, and the spa itself was distinctive enough that it didn't feel like an afterthought to the water park trip.
