Typical sizes in these listings range about 13.8–15.25 inches tall and about 2.5–4 inches wide. One description lists dimensions as 15.25 x 4 x 2.5 inches.

Some items are listed for household toilet use, while the liquid treatments are indicated for RV/automotive holding tanks and broader multi-surface or multi-purpose use.
