We are putting in a half-bath and we had it sheetrocked, but the floor was already tiled and there is a larger space than regular baseboard covers. It is an old house and the baseboard has to be at least 6" so tha the original door trim will meet it properly. It has to be 2"+ thick to cover the edge. Anyone have any suggestions? We got a 1 x 6 and another piece of molding thinking it would do it, but it isn't quite thick enough.
Try a 2x6. But seriously you could use the 1x6, if you cut spacers where the studs are located then take colonial doorstop and put that on top to cover the empty space where the spacers are, then top that with true 1/4round 3/4 in. and use same where your base meets the floor. I have run into this type of made up base in some very old homes though the components were somewhat different.
