We are carpeting over a great room currently made up of a combination of hardwood and tile.
To use a really bad analogy, let's say I am carpeting over the map of the United States (a rectangle) where every state is hardwood except for North Dakota (which happens to be an extended hearth in front of the fireplace). So I have a three-sided "hardwood/tile" transition area.
The tile is 1/8" higher than the hardwood. There is a wooden "transition" piece with a rise/run of (1/8")/(1.5").
Do you think that is sufficient?
Or should I try to "feather" this out a bit more with some thinset or something like that? If I scuffed up the hardwood and tried to create a feathered ramp with a run of more like 6-8" would that work?
I worry that over the years, the carpet and pad will get "tired" and that little ridge will start to show - and thus the outline of North Dakota.
As an alternative, could I just use a thicker pad on the hardwood?
There is a product called Carpet Shims that is used for that purpose. You will have to search online for a distributor. They are not expensive. I have used cedar shingles from the home store in a pinch. They need to be trimmed to size though.
