There are no striptease clubs in Leuven or Louvain as the French say. Sorry. It’s a shame. I think there would be a market for a reasonably priced titty bar in Leuven. Of course it should be a decently priced strip club, since students are usually on budget. Hiring a stripper online for a private event is as close as you’re going to get. E-rotic D-zire (https://striptease-boeken.be/) offers such services. There is a handful of such clubs in Brussels, but they are generally not that popular in Belgium.
In Leuven’s direct proximity you can also find some sex clubs. They are usually called privéhuizen (private houses). Scarlet Club (https://www.scarlet-club.be/nl) is located at Halensebaan 61 in Diest, a countryside town you can reach within a 30 minutes drive from Leuven. It’s a solid club with good-looking hostesses.
And then you have also El Patio, which labels itself as a “Spicy Gentlemen's Club”. It is adult wellness club, with swimming pools, sauna cabins and Jacuzzis. Its look and feel comes pretty close to the famous German FKK clubs. El Patio is situated at Staatsbaan 87 in Bekkevoort, only 30 kilometres away from Leuven.
