Wand jet positioning and hidden jet


The wand jet stays hygienic and clean because it is positioned out of the way, namely above the ceramic toilet bowl. As a result, the jet does not come into contact with urine, faeces and dirty flushed water. This also protects the wand jet and technical elements in the event of any clogs that would cause water to rise in the toilet bowl.

Clean nozzle
The wand jet is coated with a silicone-based material with dirt-resistant properties, which keep the jet clean in combination with its self-cleaning feature


Clean toilet seat
The toilet seat also consists of a special silicone-based material with dirt-resistant properties.


Clean Resin for case
Like WASHLET® seat and nozzle, several WASHLET® models also feature WASHLET® unit made of special silicone-based material with dirt-repellent properties.


Seamless toilet seat
While WASHLET® seat consists of several parts, including the heating coil in the middle, the seat itself is seamless. This gives dirt or waste less space to attack.

The WASHLET® automatically cleans the wand jet before and after each use. Even when the toilet is not being used, the wand periodically cleans itself to ensure constant hygienic conditions.





PREMIST automatically sprays water over the surface of the inner toilet bowl before every use. Due to the ceramic’s hydrophilic nature, waste washes away more easily.


To PREMIST Technology



EWATER+ is electrolysed water (EWATER+) that considerably reduces the build-up of dirt and bacteria. EWATER+ is used to clean the wand jet and ceramic toilet bowl in several WASHLET® models. Please consult the individual product detail pages to see which WASHLET® models include EWATER+ technology.
