Western Red Cedar Kiln Dried Knotty S4S 2x4

Looking for a strong, budget-friendly option for your sauna build? Our Western Red Cedar kiln-dried knotty 2x4s deliver structural reliability with that classic cedar character — without the premium price tag of clear lumber.

These boards are surfaced four sides (S4S) for a smooth, clean finish and kiln-dried to improve stability and reduce excess moisture. The natural knots give each board unique personality while still maintaining the durability and rot resistance cedar is known for.

They’re a go-to choice for bench framing, bench supports, backrest framing, and general sauna structure. And if you're building on a budget? Many customers also use knotty cedar for visible benches where a rustic look fits the vibe perfectly.

Strong. Stable. Affordable. And still 100% cedar.

Because a great sauna doesn’t have to break the bank.
