The Swash 900 offers all the standard features, like posterior and feminine wash modes with adjustable water temperature and pressure. Add on dual stainless steel wash nozzles, instant (tankless) ceramic-based water heating (which means no running out of warm water), industry exclusive “Wide Wash Spray” (which covers a wider washing area than other bidet seats), and a heated, soft close seat. There’s also an automatic “eco” power saving mode and a body weight sensor, so the seat won’t function without someone sitting on it.
