Hi all,

I've got 7 steps in my concrete-floor basement leading to a landing.
Now I'm adding a subfloor with a height of 1.25". *Stair stringers
will now rest on top of the subfloor. *Which is the best option?

1) Do nothing, (top step height reduced by 1.25")
2) Cut 1.25" off the bottom of the stringers (bottom step height
reduced by 1.25")
3) Cut 0.75" off the bottom of the stringers (0.75" reduction on top/
bottom step)
4) Build new stringers, adjusting each by 3/16"
5) ??

I'm slightly loathe to do #4, given my construction skills and the
relatively easy 'fixes' proposed in #1-3. *Thoughts?


Build the stairs properly the first time...

Fabricate new stringers that have equal spacing so that
your stairs are safe and will not have to be rebuilt at a
later time...

Why are you building a 1.25" sub-floor on top of an
existing concrete slab floor in the basement ?
That sounds very odd unless it is some sort of
over-pour to allow for the installation of underfloor
heating...
