Product Overview

The TOTO T40 WASHLET+ Nexus One-Piece Elongated 1.28 GPF Toilet and Contemporary Auto Flush WASHLET S7 Bidet Seat is designed to conceal the WASHLET+ power cord and water supply hose for a seamless installation. The WASHLET S7 features TOTO's technologically advanced EWATER+ system that mists the wand and toilet bowl, reducing the need for harsh cleaning chemicals. PREMIST wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean. The TOTO WASHLET S7 is operated by a luxury style illuminated touch button remote with 4-user memory storage to save preferred settings. The WASHLET features 5 spray settings, heated seat, and instantaneous water heating. The newly redesigned lid style resides flush with the toilet bowl, providing a streamline look and giving the impression of an integrated system. The minimalistic display provides a more subdued appearance to your WASHLET. Skirted Design toilets also minimize the need to reach behind the bowl to clean the nooks and crannies of the exterior trapway. New Auto Flush kit provides a hands-free automatic flush after every use. No need to touch buttons or handles, and never worry about someone forgetting to flush. Features TORNADO FLUSH, a hole-free rim design with dual-nozzles that creates a centrifugal washing action that assists in rinsing the bowl more efficiently. This version of the TOTO Nexus includes CEFIONTECT, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. CEFIONTECT, EWATER+, and TORNADO FLUSH create a synergy that optimizes performance to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The Nexus comes ready for install into a 12" rough-in, but may be adapted for a 14" rough-in with the purchase of a separately sold adapter. Additional items needed for installation must be purchased separately: wax ring, toilet mounting bolts, and toilet water supply lines. Compatible with T40 WASHLET+ toilet bowl components only.

TOTO MW6424726CEFGA Technologies and Benefits:

  • TORNADO FLUSH®: The TORNADO FLUSH® features two powerful nozzles that create a centrifugal, cyclonic rinsing action which reduces waste buildup and keeps the bowl cleaner. Using only 1.28 gallons per flush, this high-efficiency system is more effective in one flush than most toilets are with multiple flushes. The modern hole-free rim design means that it performs more consistently and is easy to clean.
  • CEFIONTECT®: The nano-scale glaze that creates a super-smooth, ionized barrier, which prevents particles from adhering to porcelain, reducing the need for harmful cleaning agents.
  • WASHLET®: WASHLET® Technology incorporates a unique wand that allows water to be used for personal cleaning in a way that leads to a completely new level of hygiene and comfort. The warm water cleans far more effectively than paper ever could. Its temperature and flow are easily adjusted by remote control, and the wand self-cleans before and after every use. The energy-saving mode can also be activated to increase efficiency.
  • WASHLET®+: WASHLET and toilet set with a concealed connection that is specially designed for a seamless installation.
  • EWATER+®: EWATER+® cleans the wand and toilet bowl where waste and build up tend to accumulate and create stains that can become permanent. Using no chemicals or cleaning agents, EWATER+ provides peace of mind everyday that microscopic build up has no place to hide.
  • PREMIST®: Using the incoming water supply, a Premist sprays the toilet bowl surface aiding in the elimination of waste approximately 80 percent better than a dry bowl.
  • Auto Flush: No need to touch buttons or handles and never worry about someone forgetting to flush - it’s automatic after each use.
  • WATER SAVING: Water efficient toilets designed with 1.28 gallons per flush or less.
  • HEATED SEAT: The moment you approach the toilet, the seat begins rapidly warming to a comfort- able temperature.
  • WARM AIR DRYER: Enjoy the ease and comfort of drying with the temperature adjustable warm air dryer.
