Alder is the perfect smooth cool timber to feel against bare skin... perfect to construct all the internal fittings, including benches, backrests, guard rails, etc; even the duckboards for the 'underfoot' areas are so much better in beautiful Alder...

We are probably the UK's largest stockists of Sauna Grade Alder, with stocks of anything up to 30,000 running metres, usually in a wide range of lengths...

This broad selection helps you, our customer (and the environment) by avoiding wastage of this very special timber!

All lengths are fully finished on all four sides and have all four corners 'pencil-rounded' to appx 5mm radius. Profile size (e.g. width & depth) 90mm x 28mm

Thus, allow one piece of Alder per 100mm of bench-width (90mm + 10mm gap)

Ready to cut to length - and enjoy!

We'll be happy to help you with the selection of the correct lengths for your own Sauna project from our extensive stock.

See below for lengths currently available from stock; please note this selection can change almost daily as stocks come and go.
