6+ Person Indoor Traditional Saunas — UK

Before you buy

  • Plan electrics early: 9kW+ heaters typically require 16A 3-phase, fitted by a qualified electrician
  • Allow heat-up time: larger volume = 45+ minutes to working temperature
  • Floor + ventilation: sealed concrete floor + dedicated extraction recommended
