Rim- Water, from the flushing cistern, is made to flow around the WC bowl using different designs of flush rim found at the top of the WC bowl.
- Box rim is formed from what looks like a tube with slots and holes created in its underside. Water from the cistern is guided around the rim and allowed to jet into the WC bowl through the holes and slots. In this way water is controlled to give the best flush performance.
- Open rim looks like an inverted U-shape. Water from the cistern is guided around the rim under its own rate of flow.
- Rimless These WCs have no U or slotted-tube arrangement. Water floods into the WC bowl from small jets created in the ceramic. The shape of the top of bowl (sometimes a beveled edge) prevents water from overflowing.
