If you want to buy your gift vouchers at Thermae Grimbergen, our opening hours are:

Sunday to Thursday: 10:30 to 23:00, Friday and Saturday: 10:30 to midnight, 24 and 31 December: open from 10:30 to 17:00, 25 December and 1 January: closed all day.

Frequently asked questions:

How many free day passes will I get with my gift voucher purchase?

That depends on how much you spend on gift vouchers.

100 to 199 euros = 1 free day pass

200 to 299 euros = 2 free day passes

300 to 399 euros = 3 free day passes

and so on.

This can be different gift vouchers in one purchase. For instance, you can buy 4 vouchers of 50 euros, in which case you will get 2 free day passes. But you do have to buy them all at the same time. So, if you buy 4 vouchers of 50 euros as 4 separate purchases at 4 different times, you won’t receive any free day passes.

Can I take advantage of this promotion more than once?

Sure, but every purchase counts as a separate purchase. So, if you buy a 150-euro voucher on day 1 and another 150-euro voucher on day 11, you will receive 1 free day pass with your first purchase and 1 free day pass with your second purchase. But if you buy your 300 euros worth of gift vouchers in one purchase, you will get 3 free day passes.

Is this promotion only valid online?

No, this promotion applies to both online purchases and purchases made at our centre between 9 November 2026 and 3 January 2027. Please note, if you want to pay with a gift voucher at the end of your wellness day, it must have been purchased at least one day before. The gift vouchers and free day passes are only valid from the day after purchase.

What is included in the free day pass?

A whole day’s entry to our public baths, weekdays only.

Your free day pass is valid for 6 months from the day after purchase, except on Saturdays, Sundays, public holidays (1/1/2027, 29/3/2027, 6/5/2027 and 17/5/2027), during long weekends (7/5/2027) and school holidays (between 19/12/2026 and 3/1/2027 and between 6/2/2027 and 14/2/2027). The day passes will not be extended.

Can I use my day pass both at Thermae Boetfort and Thermae Grimbergen?

Yes, you choose which centre you want to go to. You don’t have to book in advance, simply turn up with your free day pass.

Can I give my free day pass to someone else?

Yes, absolutely.
