Sauna Aquarius is an erotic sauna on the Peter Benoitstraat in Ostend, on the Belgian coast. It calls itself Erotic Wellness and runs playrooms alongside the sauna.

The important thing to know before going is that the audience changes with the day. Tuesday, Wednesday, Thursday and Sunday afternoons are men only, gay and bi. Friday and Saturday evenings are mixed, hetero and bisexual. Monday it is closed. The club keeps a separate guestbook for each of the two crowds.

The dress code follows the same split: a towel on the men's days, a towel or lingerie on the mixed evenings. Two towels are included per person, one handed over on arrival. Cash, Bancontact and credit cards are taken. There is a large paid car park beside the building.

Admission on the mixed evenings is limited for single men — the venue states it selects on what a guest adds to the club's concept and does not admit groups.
