The Aquorea floor drain is designed for buildings with poor drainage and potential odour nuisance. It reduces the evaporation in the drain and prevents vapour from flowing back into the bathroom. A silicone membrane under the cover plate blocks the airflow and effectively seals the drainage. This keeps microbes and odours in the drainage pipe. The decorative cover plates are available in different versions to integrate the floor drain into a given environment. A special slot makes it easy to clean the drainage.
