TOTO Launches New 'Purerest EX' Combination Toilet on August 3

TOTO Ltd. (Headquarters: Kitakyushu City, Fukuoka Prefecture, President: Shinya Tamura) will launch a fully remodeled version of its combination toilet 'Purerest EX' on Monday, August 3, 2026.

In this full model change, the long-popular oval tank design has been inherited, while a new 'Hose Clean' structure has been adopted. This structure routes the water supply hose and power cord for the Washlet*1 through holes in the toilet body, minimizing the exposure of hoses. By eliminating the side cover on the toilet body and reducing seams and steps in the design, an even cleaner appearance has been achieved. Additionally, the 'water surface area' has been expanded by approximately 1.4 times compared to the previous model, significantly improving the cleanability inside the bowl and reducing the daily cleaning burden.

Furthermore, even for wall-drainage specifications, which previously had different specifications, a 'rimless shape' that eliminates the back rim of the toilet bowl and a water discharge method that forcefully directs water to the back of the bowl, where waste tends to adhere, have been adopted, making the specifications common regardless of the drainage direction. This achieves high cleanability in various building conditions, such as condominium remodels*2, which often have wall drainage. The synergistic effect with TOTO's proprietary cleaning technology 'CeFiONtect' keeps the toilet clean.

TOTO positions products like this one, which balance 'cleanliness, comfort, and health' with the 'environment,' as 'Sustainable Products.' By popularizing these products, TOTO aims to contribute to the realization of a prosperous and comfortable society that is considerate of the global environment.

*5: Cleaning effect of clean sterilization water. Test facility: Kitasato Environmental Science Center. Test method: Electrolyzed water sterilization efficacy test. Sterilization method: Mix electrolyzed tap water and bacterial solution to confirm sterilization effect. Test result: 99% or more (not a verification result in actual use). Effect/efficacy: Clean sterilization water suppresses dirt and does not eliminate the need for cleaning. Effects may vary depending on usage and environmental conditions (water quality, material/shape of the object, degree of dirt, etc.). It does not mean that tap water has been sterilized. *6: Tap water and drinkable well water (groundwater). *7: Water quality safety of clean sterilization water. Test facility: Gifu Prefectural Public Health Inspection Center. Test method: Electrolyzed water tap water quality standard compliance survey test. Samples: Electrolyzed tap water / water after returning to raw water from electrolyzed water / tap water electrolyzed with an electrolytic cell at the end of its life. Test result: 100% compliance with tap water quality standards. *8: Raw water return characteristics of clean sterilization water. Test facility: Japan Food Research Laboratories / Gifu Prefectural Public Health Inspection Center. Test method: Electrolyzed water raw water return characteristics test. Sample: Electrolyzed tap water. Test result: Returns to raw water in approximately 2 hours. *9: Decomposition effect of clean sterilization water. Test facility: Japan Food Research Laboratories / Toray Research Center, Inc. Test method: Oleic acid decomposition test with electrolyzed water / Protein decomposition verification test. Samples: Oleic acid (immersed in electrolyzed water) / BSA (immersed in electrolyzed water). Test result: 95% or more decomposition (not a verification result in actual use) / 79% decomposition (not a verification result in actual use). *10: Bleaching effect of clean sterilization water. Test facility: Japan Food Research Laboratories. Test method: Bleaching effect of 'clean sterilization water' on pigment components of actual urine. Sample: Urobilin aqueous solution (immersed in electrolyzed water). Test result: 50% or more bleaching (not a verification result in actual use). *11: Effective chlorine concentration of clean sterilization water. Test facility: Gifu Prefectural Public Health Inspection Center. Test method: Electrolyzed water effective chlorine concentration measurement test. Sample: Electrolyzed tap water. Test result: 5 ppm (WHO drinking water quality guideline value) or less.
