Before You Order
Fitting the Yakia 400 L in Your Garden
Space. The cabin takes up 229 × 229 × 235cm, a footprint of 5.2m². Allow room around it for the door to open and for treating the timber each year. We measure up at the free site survey.
Access. The Yakia 400 L arrives as flat-packed panels and is built in place, so it will go through a standard side gate.
Power. The 9kW heater needs its own circuit from your consumer unit, drawing around 39 amps on a standard single-phase supply. Our electrician installs and certifies it — it's included in the price.
Planning. At 235cm tall, the Yakia 400 L is under the 2.5m height limit for outbuildings near a boundary, so in most gardens it won't need planning permission. Much of Buckinghamshire falls within the Chilterns National Landscape, the Metropolitan Green Belt or a conservation area. A garden sauna is usually still permitted development, but height limits near boundaries and rules for listed buildings apply — we check your plot before you order.
Heater upgrade. Prefer a HUUM? As an optional extra we can fit a 9kW HUUM DROP, CLIFF, HIVE Mini or STEEL with Wi-Fi control. Compare HUUM heaters.
