The only real solution I have found is to model the flights and winders separately.

If all one stair, the underside will become curved.

If modelled as separate stairs, the flights will have a flat base and you can edit the winders to have a flat base as well if you want.

If you use Barry's method, some landings may become very thick. In that case, you can even model the desired bottom surface with a Morph and subtract it from the Landing to achieve the exact desired bottom surface in all landings instead of the automatically generated bottom surface.
