I'd like to have some 1/2" thick engineered wood to replace some damaged 3/8" wood. Currently, the 3/8" is perfectly level with the tile in the bathroom and there is no transition piece of any sort. Is there a way to put in some sort of unobtrusive transition in the door to account for the slight difference in height? I don't want some gigantic, ugly lump transition piece in my two bathroom doorways. Is there a more subtle way to make the transition with 1/8" difference in height? Thanks.
