There are many safety issues on news that children were drowned in bathtub because parents were not paying attention. Hence, we’ve designed a whole new bathtub drain according to traditional drain. People can adjust bathtub drain height depending on different height of children. When water line is closer to the drain height then it will drain out excess of water. It makes children much safer and makes parents plan time much wiser.
