Here are a few rules of thumb: 1. 1/8 to 1/4 inch of thinset over the plywood. 2. Then, 1/4 inch or 1/2 inch backerboard. 3. Then, the WarmWire wire secured with Cable Strap. 4. Then 1/4 inch to 3/8 inch thinset over the WarmWire. 5. Finally, 1/4 to 5/16 inch tile. So, the overall thickness of your completed WarmWire tile floor will be about 7/8 – 1 inch thick. This is only about 1/8 to 1/4 inch thicker than a cold floor without heat.
