It may depend on your grade. Since this is a barn (and it would be fine for a sauna), I was using 2nd clear grade C shingles. Lots of knots, some defects, but $49 for a bundle from PJ Currier, a local lumber supply company.
Thanks! I feel like we just don't have the same supply chain over here for some of these products. Was a pain even finding clear cedar in any quantity.
