Somehow Lowe’s only has these things in pressure-treated lumber. So I made my own for my stairs in my basement using regular lumber. And then my basement flooded.
Well, yeah. Generally you’d want pressure treated for a basement because they should be resting and fastened directly to the concrete anyway, which would require pressure rated to meet code. Even if your basement didn’t flood, the bottom of the stringer would have rotted away because concrete wicks moisture.
There’s virtually never a time you’d want to use non-pressure treated lumber to build stringers, except above grade transitions. In which case, cutting them yourself is also stupid easy.
