Front and Rear Cleansing

Front and rear washing with oscillating and pulsating features, and adjustable spray position, water pressure and water temperature.

Instant and Continuous Warm Water

TOTO's instantaneous water heater is listed for continuous warm water, so the wash does not draw from a stored tank.

EWATER+® on the Wand and the Bowl

Electrolyzed water auto-cleans the wand and the bowl after every use — the wording TOTO uses for the S7 and S7A only.

Five-Setting Warm-Air Dryer

The dryer offers five variable temperature settings from 95ºF to 140ºF, two more than the three-setting dryers lower in the range.

Heated Seat with Temperature Control

Seat temperature adjusts between 82ºF and 97ºF, and auto energy saver mode lowers it when the seat is inactive.

Remote with Four-User Memory

The pearl white multifunction remote stores personalized settings for up to four users. The remote is listed in TOTO's pearl white finish.

TOTO S7 Installation

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.

Installation steps

  1. Remove old seat. Clean the surface around the mounting holes.
  2. Install the seat mounting bracket.
  3. Slide the Washlet onto the bracket.
  4. Connect the hose.
  5. Turn the Washlet on.

Before you start you will need:

  • A wrench
  • A Phillips-head & flat-head screwdriver
  • A ground-fault 120-volt outlet within three feet of your toilet
  • To turn off your water supply and flush your toilet

Frequently Asked Questions about TOTO S7

What is the difference between S7 and S7A WASHLET?

The difference between S7 and S7A WASHLET is that the S7A includes an auto open/close lid, making it more convenient, while the S7 does not. Otherwise, they share very similar features.

What is the difference between Toto Washlet S5 and S7?

The difference between Toto Washlet S5 and S7 is that the S7 has more premium features like oscillating and pulsating spray options, more customization, and some convenience upgrades compared to the S5.

Does the Toto S7 have auto flush?

Yes, the Toto S7 can have auto flush on certain models if it is paired with auto flush‑capable toilets or accessories. The seat itself works with the auto flush feature when set up correctly.

Which is better, S5 or S7?

Which is better, S5 or S7 depends on what you want — the S7 offers more advanced spray options and features, while the S5 gives you great comfort and performance at a lower price.

How much power does a TOTO S7 consume?

The TOTO S7 uses standard power for electronic bidet seats, similar to other models, and runs efficiently with normal household usage. Exact power draw varies by setting (heated seat, dryer, etc.), but it’s designed to be energy‑efficient.

The remote stores personalized memory settings for up to four users.

Water supply pressure is listed from 7.25 to 108.75 PSI.

Adjustable Cleansing with Personalized Wash Settings

The S7 washes front and rear, with oscillating and pulsating features.

  • Position, temperature and pressure adjust
  • Seamless seat, no gap

The pearl white multifunction remote controls every function on the seat.
