🚽Today’s Toilets Use Less Water and Make Less Noise.
Toto makes a Washlet that incorporates the company’s Actilight technology, a UV light that shines into the bowl and kills bacteria.
But Actilight Washlets work only with Toto bowls that have a zirconium glaze. (A Washlet is a high-tech toilet seat that can, for example, spritz warm water. Other companies call these luxury add-ons an electronic bidet seat or a bidet toilet seat.)
If you’re thinking of buying a one of these seats for a standard toilet from Toto or another manufacturer, check whether it requires the washlet manufacturer’s proprietary toilet technology to keep the toilet bowl clean.
