ceramic tile flooring

We were thinking of using ceramic tile flooring throughout our house, but we heard that the tile would be too heavy and we'd have to build extra support under our house. We currently have carpet and vinyl on subflooring with a crawlspace under the house. Does anyone know if it's true that we'd have to add support if we go with ceramic tiles?

Hi Darleen,

There are minimum recommendations for subfloors that are going to receive ceramic tiles. The joists should be 2x10s or better, spaced a minimum of 16 in. on center. The overall 'span' or length of the joists between supports comes into the equation also.

The flooring has to be a minimum of 5/8 plywood, to which cement backer board is added.

That's minimum, and my book, inadequate. I would require more or thicker plywood.
