London startup merges pitch-black saunas with electronic music in new leisure format
A London-based wellness startup is combining pitch-black saunas with bespoke electronic music, highlighting a broader consumer shift in the European experience economy toward introspective, health-focused spending.
London-based startup Saunasthesia has relocated its immersive wellness events to the Walthamstow Community Sauna in East London, moving from its previous Hackney Wick site. The concept merges pitch-black sauna sessions with electronic music and traditional Aufguss steam rituals to create a new category of nightlife.
This hybrid model reflects a growing trend in the European experience economy, where consumers are trading traditional clubbing for premium, health-oriented social activities. Founders William Dougherty and Omar Rivera are capitalising on this shift by reframing rave culture for an older, wellness-focused demographic.
Dougherty, who curates the music, noted that the project targets the introspective elements of club culture. “What we're sort of shooting for here is more of the aspects of rave culture that are quite introspective,” he said, highlighting how individuals connect with music internally rather than just socially.
Inside the octagonal hut, Rivera performs the steam rituals to guide attendees. “My role is very important because at that moment we are doing the event inside the sauna, I have taken control of the situation in a way,” Rivera explained, adding that he guides people through the darkness to help them open up.
The business recently secured a high-profile collaboration with English electronic musician Jon Hopkins for a February event featuring his 2024 album ‘Ritual’. Hopkins restructured his album into four chapters and added a new soundscape intro specifically for the sauna environment.
“William and Omar created something truly unusual,” Hopkins said of the partnership. “It was kind of a no-brainer to let them do whatever they felt,” he added, noting that the project required trusting the ceremony the founders had built.
Scaling this experience requires significant technical investment in custom hardware. Berlin-based sound engineer Itamar Asher designed the ‘Alephalef Nordo II’, a bespoke quadraphonic soundsystem built to withstand extreme heat and humidity.
The speakers are crafted from oil-rich rainforest plywood and feature weather-protected passive radiators with modular crossovers to prevent rusting. “It was quite a challenging room to position the speakers,” Asher said, noting the logistical need to avoid disrupting the venue's cleaning and maintenance routines.
Asher placed the units directly on the benches among the attendees, using triangular drivers facing the ceiling to create a coherent soundscape. To ensure durability and audio quality, he tests the units with harshly mastered tracks. “If you get them right [on your speakers], you'll get others right,” he joked.
The Walthamstow expansion demonstrates how niche wellness concepts are evolving into capital-intensive experiential businesses. By combining high-fidelity audio engineering with traditional thermal therapy, operators are carving out a lucrative new segment in the post-pandemic leisure market.
