All GL WASHLET installations (additional water and power connections) are guided through the ceramic, making them invisible from the outside. The WASHLET and ceramic toilet combine for a streamlined, harmonious design. The GL WASHLET has a Premist function. This sprays the inside of the toilet bowl with a fine mist of water prior to use because less dirt and waste sticks to a moist ceramic surface than a dry one. The Premist feature is activated when the toilet lid is raised. Other functions include a heated seat, dryer, adjustable warm water cleansing and a memory feature that saves individual settings for two users. All TOTO toilets are equipped with the extremely efficient Tornado Flush and have rimless bowls.
