We have two rental units that have cheap kitchen base cabinets which are

For various reasons I want to fit this "in situ." (The main reasons are
cost and the fact that we don't want to have to mess with the plumbing more
than necessary.)

Any hints? I would appreciate the benefit of the experience of anyone else
who has had this type of problem and how he managed.

Thanks in advance. I've the exact same situation, remedied by building a supporting grid of half-lapped material, and laying a 1/8 or 1/4 inch moisture resistant skin over the top. Usually you've got to cut the new floor in two in order to get it into the cabinet. Lay a bead of glue down, install the new floor, and nail in place. HTH. Tom
