Question by  JDand43 (59)

Can I put a concrete shower curb on plywood subflooring?

I don't want to over burden the subfloor.

No probably not, the subflooring could be too weak to support that kind of weight. Your best to use a lighter material.

I built mine using stacked standard 2x4's. Since the curb is outside the membrane, it should not be subject to water damage.

Should i use 2x8 or 2x10 for rafters with a 30 foot length? I do not want my roof to collapse or have any really bad weak spots in it.
