Can I install these over a tile floor? It's a 14x12 room. It will be used for exercise (Stationary bike, lunges, yoga, etc). No weights being dropped on it.

Our 6mm Energy Rubber Tiles can be installed over any hard, flat surface such as concrete, asphalt, plywood, tile, laminate, and the like. So our 6mm rubber tiles can be installed over existing tile with ease. They can also be installed over low pile commercial carpet with ease. The only thing that these tiles can't really be installed over is a high pile, thick padded residential carpet. This is due to a tripping hazard being created when the pad is depressed. To get around this issue, we recommend installing a 1/4" thick plywood board over the carpet so that the tiles can be installed on a hard, flat surface.
