Ashtrays typically are made of fire-retardant material such as glass, heat-resistant plastic, pottery, metal, or stone. It differs from a cigarette receptacle, which is specifically for discarding cigarettes after being smoked.

The most common ashtray design is a shallow cylinder with a flat base, to rest on a table. Other ashtrays, particularly in public places, are wall-mounted, and larger than standard tabletop ashtrays due to the increased use they receive. There are also public ashtrays combined with trashcans. Many ashtrays have notches at the rim, to hold cigarettes and/or a cigar. Frequently ashtrays were equipped in older large or luxury cars before later being available as dealer-installed accessory items.
