Community Sauna Baths' Peckham site is an off-grid sauna in Glengall Wharf Community Garden, with proceeds supporting the garden that hosts it. It runs two wood-fired saunas with a refreshing shower for cooling but no cold plunges, and opens Friday to Sunday during daylight hours from 9:00 AM to 7:15 PM. A 75-minute session costs £8, making it the cheapest of the not-for-profit network's London sites.
