TOTO WASHLET KS5 Compatibility

The TOTO WASHLET KS5 (SW3215#01) is a round-front electronic bidet seat. Confirm these four things before ordering.

  • Toilet bowl shape: Designed specifically to fit most standard round-front toilets. Elongated toilet bowls require an elongated WASHLET variant for proper fit.
  • Toilet tank clearance: Requires approximately 1.5 to 2 inches of flat clearance between the seat mounting holes and the front face of the toilet tank.
  • Electrical hookup: Requires a standard 120V GFCI electrical outlet located within reach of the seat's power cord (typically on the wall behind or next to the toilet).
  • Water line access: Connects directly to your toilet's standard fresh water shutoff valve using the included T-connector and flexible supply line.

For reference: Because it utilizes an intuitive quick-release docking station, the TOTO KS5 can be easily installed on your existing round toilet in less than an hour without hiring a plumber.
