Cap the floor with subfloor material. Hardie backer, plywood,
wafer board, particle board. The last 2 are not great choices for
potential water in a bathroom. Your 1" difference will require 2
layers, or 1 layer on strips, or 1 and 1/8 material unless that
gets you too high.

I am removing a tile floor and want to replace it with linoleum.
The small mosaic type tiles came up very easy as the concrete
type leveling substrate had deteriorated into a powder. However,
now I'm left with an inch or so difference in floor heighth
between the adjacent room and a very uneven plywood subfloor.

Thanks for any suggestions.
