This Thermo Aspen sauna step board is premium A grade Thermo Aspen, a profiled step and backrest board, machined for sauna use and supplied in a pack of 16 lengths of 28 x 65mm x 1.8m. Each pack gives 28.8 linear metres. The 1.8m length is ideal for horizontal cladding, spanning vertical battens with little waste and easy to handle in a small sauna, cabin, bathroom or garden room.
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.
Uses
Use step boards for sauna bench steps, backrests and edge details, alongside our matching bench boards.
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. These short lengths also suit horizontal slatted wall cladding, bench fronts and skirting boards, fixed across vertical battens with a 5 to 10mm gap.
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 I fit it horizontally?
Yes. 1.8m lengths are ideal for horizontal cladding across vertical battens at 400 to 600mm centres.
Is delivery included?
Yes. The price includes VAT and delivery, with no extra charges at checkout.
Also available in 1.5m (pack of 24), 2.4m (pack of 16), 2.7m (pack of 8), 3m (pack of 8). Browse all sauna timber, sauna wall panels and sauna bench boards.
