Insulated electric sauna

I am selling my hand build insulated outdoor sauna, fully hooked up and ready to go with an 8.5kw heater. I built the sauna using the Finish sauna principles and quality materials. - 100mm Rockwool Insulation throughout walls and roof. - Comfortably sits 4 people on the high bench, but can accommodate 5 people, and an additional 2 on the lower bench. - The sauna is approximately 3.3m * 1.75m - Finish sauna design utilising high bench to ensure your head is positioned in the löyly zone (optimal heat layer), as well as ensuring proper airflow and heat retention. - 8.5kW SAWO electric sauna heater (it's a Finnish brand). - Fully wired with isolator switch. - Heats efficiently, reaching 30°C in 15 minutes and 80°C in 1 hour. - Moveable lower bench to allow for hot yoga or stretching; can be easily secured in place if desired. Extras: Comes with 2 sauna hats, a bamboo sauna pillow, and a thermometer & hygrometer.
