Build quality is excellent. Assembly is very easy (only required assistance to lift front panel in place). The harvia 3kw heater is great. The lighting is great. All required accessories included (bucket, ladle, thermometer, timer etc)
If you really wanted to you can sit 1 person across the bench and stand 1 person up.
Electrician required to install isolator switch and dedicated line to switch board.
The only negative which could be redesigned is that the lighting feeds off the heater. So when the thermostat turns off heater when it reaches temp... the light also goes off. Other than that the sauna is excellent and have emjoyed the first session. It will give you a proper roasting if you turn the heat up and wet the stones.
Overall im exceptionally happy with the purchase and would reccomend it. If i had space i would have gone with a bigger sauna.
