Powerful TORNADO FLUSH® Performance

The UltraMax WASHLET+ S7A combines TOTO's proven TORNADO FLUSH technology with a highly efficient 1.28 GPF water consumption rate to deliver exceptional bowl cleaning performance. Dual-nozzle cyclonic rinsing creates a powerful swirling action that reaches every area of the bowl, helping reduce waste buildup while using significantly less water than traditional toilets. Combined with the rimless bowl design and CEFIONTECT ceramic glaze, each flush leaves the bowl cleaner with less effort and fewer repeat flushes.

Intelligent Hygiene & Hands-Free Convenience

Designed to provide a cleaner and more comfortable bathroom experience, the WASHLET S7A incorporates TOTO's most advanced hygiene technologies. PREMIST automatically wets the bowl surface before use, while EWATER+ sanitizes the wand and bowl after every use. Touchless Auto Open/Close functionality, automatic flushing, a heated seat, warm air dryer, and automatic deodorizer work together to create a luxurious, low-maintenance experience that minimizes contact with surfaces and reduces everyday cleaning requirements.

TOTO UltraMax WASHLET+ S7A Compatibility

The TOTO UltraMax WASHLET+ S7A is an elongated one-piece toilet with an integrated WASHLET+ bidet seat system. Confirm these items before ordering.

Rough-In Measurement:
Designed for a standard 12-inch rough-in. Measure from the finished wall (not the baseboard) to the center of the floor drain.

Floor Space Requirements:
The elongated bowl extends farther into the room than a round-front toilet. Verify sufficient front clearance and at least 15 inches from the bowl centerline to any side wall, cabinet, or obstruction.

Water Supply Location:
Requires a standard ½-inch water supply shutoff valve. The water connection should be positioned where it can be accessed by the included WASHLET connection hardware.

Electrical Requirements:
A nearby 120V GFCI-protected outlet is required to power the WASHLET S7A's heated seat, warm water cleansing, dryer, auto flush, auto open/close lid, and other electronic features.

Drain Configuration:
Compatible with floor-mounted drain installations only. Wall-drain applications are not supported.

Flooring Compatibility:
Suitable for installation on tile, vinyl, laminate, hardwood, concrete, and other standard bathroom flooring surfaces with a properly installed closet flange.

WASHLET+ System Requirements:
The concealed WASHLET+ design is factory-matched to this toilet and seat combination. No additional adapters or exposed supply hoses are required when installed according to TOTO specifications.

Installation Considerations:
The one-piece toilet and WASHLET assembly are significantly heavier than a standard toilet. Two-person installation is recommended for safe handling and positioning.

Installation Steps

Turn off the water supply valve and flush the existing toilet to empty the tank and bowl.
Disconnect the water supply line and remove the old toilet from the floor flange.
Clean the flange area thoroughly and remove any remaining wax ring material or debris.
Install a new wax ring or approved toilet seal onto the closet flange.
Carefully lower the UltraMax toilet onto the flange bolts, ensuring the outlet aligns properly with the seal.
Tighten the floor bolts evenly until the toilet is secure and level. Avoid overtightening, which may damage the ceramic.
Connect the toilet's water supply line and turn the water back on.
Install the included WASHLET S7A seat according to the mounting instructions.
Connect the WASHLET water supply connection and plug the unit into a dedicated GFCI-protected electrical outlet.
Pair the remote control, test flushing, cleansing functions, auto flush, and auto open/close features, then inspect for leaks.
