Description
Thermory's SHP thermo aspen bench boards are a durable, sustainable choice for a sauna bench, milled here to a slender 28 × 42 mm section with smoothly radiused R3 edges. Heat treatment reduces the moisture content of the soft timber, leaving a tough, rot-resistant board that secretes no resin in the heat and humidity of the sauna. The grain is straight and knot-free, with a honey-brown colouration and a pleasant toasted scent, making it a comfortable and stylish timber choice. Supplied in packs of eight, in 2100 mm or 2400 mm lengths, the boards are well suited to a DIY project; alternatively, our Sauna Bench Fabrication Service can build them into your ideal bench system.

Timber
Thermo aspen is created by heat-treating the soft timber. The natural heat treatment reduces the moisture level of the wood, giving it a tough, rot-resistant structure that does not secrete resin in the high temperatures and moisture-rich environment of a sauna. The grain is straight and knot-free, with a honey-brown colouration and a pleasant toasted scent. As a natural product, timber shows some colour variation between different packs and batches.
Profile
SHP is the standard timber profile for sauna bench boards: a rectangular section with radiused corners, usually R2, R3 or R4 (a 2, 3 or 4 mm radius on each edge). The radius value describes the smoothness of the board edge; these boards are R3. The 28 mm thickness is important to prevent the boards warping and twisting over time.
Quality & Wastage
This thermo aspen timber is A-grade: durable, knot-free and with a low risk of splintering. We recommend a wastage allowance of 15% for SHP sauna bench boards, which also accounts for any risk of damage in transit. General grading standards apply to this sauna wood; the grading rules for different sauna wood types, and our interactive Bench Board Calculator for working out quantities, are available at finnmarksauna.com. Contact us if you are unsure how much you require for your sauna build.
Installation & Care
The boards are well suited to a DIY bench build; alternatively, our Sauna Bench Fabrication Service can create your ideal sauna bench system from them. Other timber choices are available in our wider SHP sauna wood bench board collection at finnmarksauna.com, depending on the overall aesthetic and style of your sauna.
Brand
Thermory, founded in Estonia in 1997, is the largest manufacturer of thermally modified wood in the world; its fully natural, chemical-free thermally modified timber is the company's signature product.
Ordering & Delivery
Timber orders ship on a palletised service due to their size, and may require a kerbside drop or handballing off the freight vehicle. Costs are calculated at checkout and vary between UK Mainland, Highland and Island postcodes. Lengths up to 2400 mm ship at standard rates; beyond that, shipping costs rise significantly. If we do not stock your required length but have a longer one available, our cutting service can cut it down for a small fee: you purchase the full length and the off-cut is added to the pallet. For longer lengths, the cutting service, or advice on sizes and quantities, call +44 (0) 20 8050 2895 or email support@finnmarksauna.com.
