There are formulas used in the industry to determine if the subfloor has excessive `deflection` [bounciness. lack of rigidity]. The most cited one is the Tile Council of North America standard for deflection. which is stated as L/360 as a minimum. before tile underlayment is installed. L/360 means that the floor should not bend under weight more than the length (expressed in inches) of the unsupported span divided by 360. For example. if the span between supports runs for 20 feet then the deflection should not be more than 2/3" between the center and the end. L=20 x 12" = 240". L/360 = 240"/360 or 2/3". So 2/3" is the maximum amount of movement the center of the span should be allowed to move.
If a subfloor displays excessive deflection. it can usually be remedied by installing more plywood on top of it before tile is laid. and by reinforcing the joists from below. While it may make the floor higher than before. think of it as a sort of `insurance policy` against flooring failure.
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.
One of the most traditional flooring ideas to go for is using terracotta tiles. You can get a handcrafted look for your floors with this kind of tile. You can use it in the regular square shape or get ones in octagon shapes. etc. Put a picture on your floors with mosaic tiles. You can make a pattern or lay them out randomly for a unique design. Lastly. you`ve got glass tiles. These can be used as tile flooring ideas to give a quality finished look to any room.
