Inside

Hinoki and sugi

Hinoki cypress is the timber we recommend for the inside of a sauna. It’s durable enough to need no treatment at all, and its scent is calming. Sugi, Japanese cedar, comes second. Both come from plantation forests in Japan, where no old-growth trees are harvested, and the timber is GOHO certified, meaning it’s legally harvested and tracked through the supply chain.

Hinoki cypress has lined Japanese bathhouses and shrines for more than a thousand years. When it warms, hinoki gives off a light, lemony scent. Every Heritage interior is left uncoated, with no products of any kind, natural or otherwise, so volatile organic compounds stay extremely low. New Zealand-grown redwood is an alternative, though it needs treating when it’s milled into panels.

In a 2018 study in the Journal of Wood Science, people who rested a palm on uncoated hinoki showed calmer prefrontal brain activity than when they touched marble.

Outside

Matched to your home

The exterior is clad to sit with the house it belongs to, and we can match any home’s cladding. At Taumata Road that meant board and batten, matching the existing home detail for detail.

  • Board and batten
  • Horizontal bevel-back weatherboards
  • Horizontal rusticated weatherboards
  • Vertical shiplap weatherboards
  • Cedar shingles
  • Burnt yakisugi
  • Corrugated iron
  • Stone
THE STEEL

Roof

The roof is finished in New Zealand Coloursteel, a material chosen for strength in all seasons. Coastal winds, alpine snow, heavy rain, the sauna endures them all. On bespoke builds, alternative roof profiles and stone detailing are available to suit the architecture.
  • Long run steel from rich New Zealand iron sand
  • Low-maintenance and enduring finish
Nature’s own insulation

Insulation

In a solid timber build, New Zealand wool sits between each log, under the floorboards and in the ceiling. It seals and breathes with the timber, keeping the warmth in without compromising the construction.
  • 100% New Zealand wool
  • Renewable and chemical-free
Heat

Heat

As the official New Zealand distributor of HUUM, we specify HUUM heaters as standard. HUUM builds its heaters by hand in Tartu, Estonia, and their large stone capacity gives a soft, even löyly when water hits the stones.

We’ll fit another brand if you’d prefer one. Electric or wood-fired is your choice: at a main home, people often choose electric, started from an app on their phone. At a holiday home, many prefer a wood-burning heater for the soft light of the flame and the sound of the wood.
