This Thermo Aspen sauna bench board is premium A grade Thermo Aspen, a bench board with all four edges softly rounded, machined for sauna use and supplied in a pack of 8 lengths of 28 x 140mm x 2.1m. Each pack gives 16.8 linear metres.
Why Thermo Aspen for saunas
Thermo Aspen is aspen that has been heat treated at high temperature. This gives it a warm, even brown colour right through the board and makes it more stable and resistant to moisture, while keeping aspen's resin-free, splinter-free and cool-to-touch qualities. It is kiln dried and planed smooth, ready to install.
How many bench boards do I need?
As a guide, allow one 140mm board for every 150mm of bench depth (the board plus a 10mm gap). A typical 500mm deep bench needs about 4 boards across its depth. Each board is 2.1m long, so check the length against your bench span.
Installation
Fix bench boards from underneath to hardwood or sauna-grade bearers with stainless steel screws, so no metal is exposed on the seating surface, and leave a 5 to 10mm gap between boards for air flow.
Finishing and care
Leave untreated inside the hot room, or finish with a sauna wax or paraffin oil made for saunas. Never use varnish or ordinary paint inside a sauna. Wipe benches after use and let the sauna dry out with the door open.

Frequently asked questions
Can I use this timber inside the hot room?
Yes. Thermo Aspen is a traditional sauna timber with low heat conductivity, so it stays comfortable to touch, and it is resin-free so it will not weep sap in the heat.
Do I need to treat it?
No. It can be left untreated. If you want extra protection, use only a sauna wax or paraffin oil made for saunas, never varnish or ordinary paint.
Can it be fitted horizontally?
Yes, it can be fitted vertically or horizontally over battens. For horizontal cladding our shorter 1.0 to 1.8m lengths reduce waste.
Is delivery included?
Yes. The price includes VAT and delivery, with no extra charges at checkout.
Also available in 1m (pack of 16), 1.2m (pack of 12), 1.5m (pack of 12), 1.8m (pack of 8), 2.7m (pack of 4), 3m (pack of 4). Browse all sauna timber, sauna wall panels and sauna bench boards.
