Built for heat,
humidity and time

Every piece of sauna timber we supply is carefully selected for the demands of the environment. No resin. No defects. Graded and inspected so your installation performs from day one and holds up for decades.

We carry both traditional species — Aspen and Alder — and a full thermally modified range for clients who require enhanced performance, superior moisture resistance and a richer, deeper tone.

Quality & Grading

Graded at source,
verified before shipping

Every board is graded A or Grade B at the mill before it reaches us. We inspect again before packing. Our standard means no splits, no large knots, no resin pockets — the things that cause problems in sauna environments.

FAQ

Common
questions

What timber species are best for sauna use?

Aspen and Alder are the most popular traditional choices — they are naturally resin-free, stay cool to the touch and handle high humidity well. For enhanced performance, Thermo Aspen and Thermo Alder offer superior moisture resistance and deeper, richer tones.

What is the difference between traditional and thermally modified sauna timber?

Traditional species like Aspen and Alder perform excellently in standard sauna conditions. Thermally modified timber — Thermo Aspen, Thermo Alder and Thermo Radiata — goes through a heat and steam treatment process that dramatically improves dimensional stability, moisture resistance and durability. No chemicals are used.

What profiles are available for sauna wall panels and bench boards?

We stock standard tongue-and-groove profiles in 90mm and 120mm widths for wall panels and ceilings. Bench boards are available in multiple thicknesses and widths. Custom profiles and lengths are available on request.

Are your sauna materials resin-free?

Yes. All species we supply for sauna use — Aspen, Alder, Thermo Aspen, Thermo Alder and Thermo Radiata — are naturally resin-free and safe for high-temperature sauna environments.

Do you supply bench legs and sauna construction components?

Yes. We supply bench boards, bench legs and barrel sauna components alongside our wall panel range. Contact us with your project specifications for a full quote.

Can I order samples before committing to a full order?

Yes. We offer free samples on request. Contact us and we will send you samples of the species and grades you are considering.
