Koti's Lomas de Chapultepec site is its largest, built for social contrast sessions: one spacious group sauna for up to 25 guests, three cold plunges and fully separate private changing areas. Koti's saunas combine traditional dry and infrared heat at 80–90 °C, with plunges at 3–10 °C. The space can also be booked privately for groups. A starter pack of three 60-minute sessions, valid in Condesa or Lomas, costs MX$1,000.
