A new generation club

B4, also known as Before Sauna Club, opened in 2017 in Sainte-Luce-sur-Loire, just a stone's throw from Nantes. Across 750 m² spread over two floors, the venue bets on a polished lounge style decor, a bit in the Buddha bar spirit, far from the sometimes dated image that clings to certain swingers clubs.

Bar, terrace, sauna, jacuzzi, spa area and pool make up the bulk of the amenities. A dance floor with a DJ livens up the evenings, for those who also want to dance before or after.

Who comes here

The club welcomes couples, single women and men, whether gay or straight, as well as transgender people. That's one of the things that sets B4 apart: it doesn't limit itself to a single crowd and organizes swingers nights, gay nights and mixed nights depending on the day of the week.

The dress code stays classy, sexy is fine but sloppy isn't. Entry is reserved for adults aged 18 and over.

Prices and hours

B4 is open every day from noon to 2am, with hours sometimes extended depending on the night. As for prices, they vary quite a bit depending on your profile and the theme of the day.

  • Single woman: 5 to 10 euros
  • Transgender person: 10 euros
  • Couple: 20 to 55 euros depending on the day

What regulars think

Feedback often highlights the cleanliness of the place and the professionalism of the welcome, two points that come up almost systematically in reviews. The atmosphere is described as friendly, rather upscale for the category, with a crowd that plays along with the dress code.

Some visitors find the drinks pricey, a classic complaint for this type of venue. Others mention occasional concerns about security, without it undermining the club's overall rather positive image.
