Tile over Tile over Radiant Heat
The tiles all seem to be set correctly - there are chips around the edges, one "gouge" about 1 inch around, and a few cracks that are not lifting.
The tile store quoted $2/square foot to demolish, and at 1700 square feet of tile, I don't know if it's worth it. BUT, If we tile over tile, we still have to adjust doors, remove and adjust outdoor french and sliding doors to adjust height, raise 2 toilets (?), and whatever else needs adjusting. The cost of adjustments may make demolition seem cheap...???
