We wouldn't recommend using foam as a salon floor. These tiles would indent if walked on with high heels; also, when wet, they would be a slip hazard. If you put any heavy chairs on the floor, they will leave indentations unless you put furniture sliders under the chairs. We would recommend rubber tiles. Rubber tiles are slip resistant when wet, add comfort underfoot, will not indent under high heels or chairs, and are very easy to clean and maintain.
