I have an old home where the cement basement floor is far from smooth
and level. In anticipation that we will someday need a new washer and
dryer, and noting that some of them rotate at high speeds and need a
solid base, I am thinking of having a plumber put in a new access to the
sewer line (the pvc pipe the washer drains into; we now have just a
basin), and a cement pad big enough for the new washer and dryer. Since
the floor is thin, I anticipate the pad will be thicker and may extend
above the floor, as those I have seen do. I don't know yet if there is
sufficient clearance over the existing sewer to make the pad thicker,
but even with the old floor. I think it may be traditional around here
to elevate it, as our basements do sometimes have minor flooding.
I haven't selected the models yet, but the ones I have looked at seem to
have different footprints. I want the pad to be big enough to
accommodate whatever models we buy, but not so big that it is a tripping
So what would be a good size to make this?
