Floors should be monolithic, slip resistant even when wet, yet relatively smooth and easy to sanitize. Commonly used flooring materials include troweled on or broadcast polymer (typically epoxy but methyl-methacrylates are also used) composites ranging in thickness from 1/8 to 1/4 in. Many floor coverings work well in a rodent room, including vinyl with sealed seams if the cage racks are not to heavy, but

few materials work consistently well in hard use, high-moisture areas such as cage sanitation. Ceramic tile with epoxy grout top dressing (Figures 8.5 and 8.23) has proven to be a relatively maintenance-free floor for cage sanitation areas, where seamless composite polymer floors too often fail. Grouted tile floors are not suitable for corridors, because the joints cause excessive noise when cage racks roll across it. There should be a minimum 10 cm (4 in) high V2 in. radial coved base to form a watertight seal at the floor-to-wall junction and facilitate sanitation.
