The Haven 4 Person Outdoor Sauna gives you enough room to share the heat without turning the backyard into a commercial spa complex. Your own private retreat, just steps from the back door. At 210cm wide and 180cm deep, it is the middle-sized Haven model and a strong all-round option for couples and families.
Inside, Japanese cedar, double-layer benches, backrests and LED backlighting create a warm and comfortable sauna space. The painted black exterior, sloping shingle roof and glass entrance doors give it a modern architectural look, while the included wall-mounted Harvia heater provides the actual heat ,not just some coloured lights and positive thinking.
The Haven Difference
Premium Japanese cedar, modern black styling, LED backlighting and genuine wall-mounted Harvia heaters come together to create a proper outdoor sauna experience for Kiwi backyards. They’re chic enough to look like part of the landscaping, not an overpriced shed. Quality where it counts, without the inflated wellness-retreat price tag, or any mystery timber held together by optimism.

Important Info
Japanese cedar is a natural timber and will gradually change when exposed to outdoor conditions. To help maintain the sauna’s appearance, install it on a level, well-drained surface, keep the base clear of standing water and allow good airflow underneath and around the structure. The exterior is finished with UV-stable paint, but like any painted surface in the New Zealand sun, the colour will fade over time. Repainting with a suitable water-based, environmentally friendly exterior paint will help keep it looking fresh. Regularly check the exterior, roof and seals, and address any maintenance before small issues become considerably less relaxing ones.
This sauna must be installed and hard-wired by a licensed electrician. It’s not plug-in ready, and professional installation is highly recommended to ensure safety and compliance with New Zealand electrical standards.
Install the sauna on a level, stable and well-drained base, keep it clear of standing water and allow good airflow underneath and around the structure.
Damage resulting from incorrect assembly or installation, an unsuitable base, poor drainage, inadequate maintenance, extreme weather events or exposure that goes against these placement recommendations may not be covered by the product warranty. This does not limit any rights available under the New Zealand Consumer Guarantees Act.
Freight Info:
Due to the size and weight of these saunas, standard delivery is quoted as driveway drop-off only. The sauna arrives as a large-piece kitset packed in crates, with one package weighing up to 820kg, so you will need a clear plan for unloading and moving it into position. Our delivery partner will contact you beforehand to arrange a suitable delivery day and time, so there should be no surprise sauna turning up while you are out buying milk.
Need something different? We can also help arrange HIAB delivery closer to the installation area or delivery to a freight depot for collection. Contact us at support@containerdoor.co.nz to discuss the best option for your site.
