A converted industrial yard on Ilderton Wharf in South Bermondsey, unassuming among warehouse units. Three large wood-fired timber saunas stand on an open outdoor terrace, paired with three icy cold-plunge baths kept near freezing for contrast therapy.

The setting is raw and industrial — concrete, timber cladding and open sky rather than spa polish — softened into a calm, welcoming space. A women-owned, LGBTQ+-friendly venue with step-free access and gender-neutral facilities, it doubles as a studio and treatment space for sound baths and events.

  • off-peak weekday slots are cheapest and quietest.
  • ask about the £5 concession rate, they genuinely offer it.
  • it's a wood-fired outdoor yard, not a polished spa — dress for the cold air between rounds.
  • the plunges sit near freezing; go in slow and breathe.
  • watch for the sound-bath-in-the-sauna events, they sell out.
