James and SDS were fantastic. We embarked on a DIY sauna build with no idea! James took us through the options and helped us select not on the right heater but accessories needed. They took additional calls from me as I fumbled my way through the build and we ended up with a 5 star service and a great sauna. HUUM 13KW wood heater. Takes 30 min to get to heat and sits comfortably at 80c with 10% humidity.
