Lots of hair usually shed off during showers; these hairs would collect around the drain, not only causing the drainage to slow but also becoming a source of bacteria and insect growth. As hairs flow into the drain, they may block the drainage system and/or pollute the waterway.Stay Out uses a comb-structure around the drain to block debris such as hair from flowing into it. These debris would be kept on the surface of the drain but would not slow the water flow. Periodically remove the hairs collected on Stay Out to ensure a clean shower room.
