How thick is the subfloor and what is it made of? In new construction. ¾ inch plywood or Oriented Strand Board is a standard subfloor over joists that are 16 inches on center apart. We find that is almost never enough to meet the deflection standards in most homes. Other times there is old plank flooring beneath a layer of plywood. This is a wild card. since the engineering tables usually don`t include the value for planks in their calculation. but common sense says it does add some stiffness.
What floor covering was on the floor before? If it had ceramic tile or stone. and the floor received reasonable traffic for years with no cracking or broken grout. it`s a pretty good bet that the subfloor is up to the job. If it was vinyl. carpet or hardwood. we are still in the dark.
You also have ceramic tiles. This kind of tile is the inexpensive way to achieve the look of granite or marble floors. They can give the effect of having water on your floors that`s oh so dramatic. Another kind of tile you can use as flooring is metal tile. These are either industrial gratings or stainless steel. If you want your floor to have the look of brass. bronze or steel. this is the one to go for. You can mix and match this tile with other kinds of tiles to accent the floor and create a point of interest in the room.
How tough is the tile to be installed? Fairly thick quarry tiles. for example. may be rated for heavy duty industrial applications. although they are often installed in homes. Because they are thicker than normal tiles and able to withstand heavy traffic. they may be less prone to cracking than a sensitive. thinner tile. For that matter. natural stone such as marble and granite are on the other end of the spectrum - they crack even easier than ceramic tile and should not be used in settings where any excess deflection is possible. Intuition may tell you they are stronger than ceramic. but in fact they are more brittle and prone to cracking. They need twice as rigid a floor as ceramic.
