EWATER+ & PREMIST Cleaning

The Toto S7 cleans itself with EWATER+, which rinses the wand and bowl after each use.

PREMIST sprays the bowl lightly before use to help prevent waste from sticking.

This keeps your toilet hygienic with minimal effort.

TOTO Washlet S7 Compatibility

The TOTO Washlet S7 works with most standard toilets. Confirm these four things before ordering:

  • Bowl shape: Available in round and elongated versions. Order the version that matches your toilet's bowl shape.
  • Tank profile: Your tank should meet the bowl at roughly a 90° angle. French curve tanks that slope into the bowl are not compatible.
  • Mounting hole spacing: Measure between the two seat bolt holes at the back of your bowl. They should be 5.5 inches apart.
  • Tank clearance: You need at least 2 inches of flat space between the front of the tank and the seat mounting holes.

For reference: The S7 fits both one-piece and two-piece toilets.
