The short answer

Both aspen and alder are excellent, cool-to-the-touch, low-resin bench woods. Aspen is very pale and essentially scentless (ideal for the scent-sensitive); alder has a warm reddish tone and a mild, pleasant fragrance. Either makes superb sauna benches.

When it comes to the wood your skin actually rests on — the benches — aspen and alder are two of the best choices. Both stay cool and splinter-free; they differ mainly in colour and scent.

Very pale, clean-grained, and essentially scent-free.

Why not cedar for benches?

Cedar is a fine bench wood too, but its strong aroma bothers a minority, and aspen or alder are often preferred precisely because they are cooler-feeling and gentler-scented. Many saunas use cedar or hemlock walls with aspen or alder benches — a popular, excellent combination. Whatever you choose, keep bench wood knot-free, bare, and cared for by light sanding, as covered in our interior wood guide.

Picking on look and scent

Because both aspen and alder are outstanding bench woods — cool to the touch, low-resin, and splinter-resistant — the choice really comes down to look and scent preference rather than performance. Aspen is very pale, clean-grained and essentially scentless, which suits a bright, modern sauna and anyone sensitive to wood aromas. Alder is warm and reddish-toned with a mild, pleasant fragrance, giving a cosier feel.

You genuinely cannot go wrong with either for the parts your skin touches, so trust your eye and nose. If you want the palest, most neutral look, or zero scent, choose aspen; if you want a warmer tone with a hint of fragrance, choose alder.

Many saunas pair these bench woods with cedar or hemlock walls — a popular combination that uses cedar aroma and durability on the walls while keeping the benches cool and gentle-scented. Whatever you choose, keep bench wood knot-free, bare, and cared for by light sanding, with an optional food-safe sauna oil the only treatment.

Because the difference is purely look and scent, the safest approach is to see and, if you can, smell samples before deciding. Both will feel cool and comfortable against your skin and last well as bare, lightly sanded bench wood, so trust your preference — the pale neutrality of aspen or the warm, gently fragrant character of alder.
