Common shapes are rectangle, round, and wedge (semicircle). Typical dimensions range from about 30" x 18" and 34" x 21" for small mats to round sizes like 24" x 24" and larger wedge pieces around 36" x 20".
Backings vary: some rugs include latex or PVC non-skid backing, others use suction cups or molded perforated TPR for grip, and some list no backing and are intended for use with a separate rug pad.
Care varies by rug: many list machine wash and tumble dry; some recommend spot or wipe cleaning with line-dry or lay-flat drying; and at least one specifies machine wash in cold water with no dryer.
Listings show sizes intended for sinks and showers, for example pairs that include 17" x 24" and 21" x 34", and single mats around 30" x 18" that fit well in front of a sink, shower, or bathtub.
Fabric-weight categories shown range from Lightweight (300-450 GSM) up to Heavyweight (550-800 GSM). Pile heights range from flat or low pile (flat or under 0.5") up to medium pile (0.5"–1").

Washing and drying guidance varies: many rugs list machine wash and tumble dry, some advise spot or wipe clean with line-dry or lay-flat drying, and at least one specifies machine wash in cold water and no dryer.
