Hi guys,
Well I've decided that instead of adding an extension to my current hearth pad for my soon to be installed Lopi Republic 1750, I'm going to tear out the current brick hearth pad and install a new tile one. This stove only requires ember protection, so I don't need very much under the stove.
I have a very specific question I'm hoping someone can answer. Normally under tile One would have the subfloor, 3/8" plywood, cement board, then the tile. I'd like to skip the plywood and put the 1/4" cement board directly on the subfloor in order to keep the height of the tile roughly even with the height of the finished floor it will meet with.
The floor joists are true 2x6s, to which I've sistered up modern 2x6s in order to stiffen the area under the stove. This was mostly just for piece of mind, not because I detected any sort of problem. The stove is in the corner of the house, so there shouldn't be much deflection in the floor at the point anyway.
So my question is this; Will I be OK skipping the plywood? No one will be walking on this surface, but it will have a 430lbs stove on it. I don't want to install all the tile and then find that it all cracks and breaks when I sit a stove on it.
I'll use mortar under the cement board to give it a 100% footprint, and screw every 6". I do not detect any movement in the subfloor when I walk on them. No creaks or sounds.
Any thoughts?
