The large, watersports-friendly shower can hold 6 or more people easily, and we will also have a plastic wading pool and/or a bathtub for more wet play.

Tickets will be $20 in advance (plus Eventbrite fee), or $30 at the door.  All proceeds will be donated to the San Francisco Bay Area Leather Alliance, to keep the doors open at the all-volunteer SF Catalyst space.  Discounts available for volunteers (see below to contact me for info).

  • Bring your own beer in cans; plenty of water and salty snacks will be provided.
  • Be 18+ with ID.  Be 21+ if you plan to bring beer.
  • Anyone who identifies as a male is welcome.
  • Consent is sexy. No means NO.
  • Wet play in designated areas only.
  • Rubber or other wet-friendly fetish gear and toys welcome, or get naked.
  • Bring a lock for the lockers, if you like.
  • Keep some kind of shoes on.
