I'm beginning a kitchen renovation and the first thing I'm looking into is replacing the tile the previous owners had installed. My entire house is hardwood, possibly original (from 1954), aside from my kitchen which was redone as tile. The tile in the kitchen is a good 3/4" taller than hardwood in the adjoining room. I chipped off a small piece of tile to see what I was working with. There seems to be four layers, the subfloor, a layer of tar paper, a fiber backer board and then the tile.
Now the question I have is when I compared the portion of bare subfloor to my hardwood floors in the adjoining room, the hardwood part only seems to be ~1/8" thick!? What kind of Hardwood construction is this? If I wanted to put hardwood in my kitchen how would I go about matching the height with the room next to it?
