TOTO WASHLET S5 Compatibility

The TOTO WASHLET S5 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 S5 fits most one-piece and two-piece toilets with standard mounting holes.

Before you start you will need:
