Upgrade Your Bathroom with TOTO’s New 2026 Washlet KS5 – Elongated

Experience the most advanced elongated-front Washlet yet with the all-new KS5 from TOTO (SW3216#01). Released in June 2026, this premium bidet seat combines continuous warm water cleansing, heated seating, warm air drying, and a multifunction remote with memory settings for up to four users. Designed with CLEAN RESIN® protection and a built-in night light, it delivers a complete, high-end cleansing experience in a compact round fit.

Key Features

Advanced Personal Cleansing

Experience a spa-like cleanse with gentle aerated warm water sprays for both front and rear washing, featuring adjustable pressure along with oscillating and pulsating functions. Customizable temperature settings for both the water and heated seat allow users to tailor comfort to their preferences, while the integrated warm air dryer provides a complete cleansing routine without the need for toilet paper.

CLEAN RESIN®

TOTO's Clean Resin® material helps keep your Washlet spotless between cleanings by resisting the buildup of dirt, waste, and stains. An anti-fouling component is embedded directly into the resin, creating a protective surface that makes debris less likely to stick and easier to wipe away. By making surfaces less likely to attract and hold debris, the KS5 stays cleaner and more hygienic while reducing the need for routine maintenance.

Personalized Remote Control & User Memory

The multifunction remote control allows users to easily adjust spray settings, temperature, and comfort features with intuitive precision. Personalized memory settings store preferred configurations for up to four users, making daily routines more convenient for shared households.

Warm Air Dryer & Night Light Illumination

The integrated warm air dryer provides a comfortable, hands-free finishing step after cleansing, with three adjustable temperature settings for a more personalized experience. A built-in night light softly illuminates the bowl interior, improving visibility in low-light conditions without harsh overhead lighting.

TOTO KS5 Washlet FAQ

What bidet wash functions does TOTO’s Washlet KS5 include and how do they work?

The KS5 includes multiple wash modes, including front and rear cleansing with gentle aerated warm water. Users can adjust water temperature, spray position, and pressure levels to fine-tune the wash experience based on personal preference. It also includes oscillating and pulsating spray functions, which move the nozzle back and forth or vary water flow intensity to improve coverage and cleansing effectiveness.

What makes the KS5 different from other TOTO Washlet models?

The KS5 Washlet stands out because it combines premium cleansing features with advanced user customization, including a multifunction remote with memory settings for up to four users. It also includes a night light and warm air dryer, making it one of the most complete Washlet systems for households that want full comfort and automation.

Will the KS5 TOTO Washlet work with my existing round toilet?

TOTO’s KS5 Washlet is designed to fit most standard elongated toilet bowls, including many TOTO and non-TOTO models. To verify your toilet's shape and dimensions before purchasing, call our customer service team at 888-682-5956 (toll-free)!

How difficult is installation for a TOTO KS5 Washlet?

The SW3216#01 is designed to fit most standard elongated toilet bowls, making installation straightforward. It uses a docking station system with included water supply hoses and a standard 120V power connection, so most setups can be completed with basic tools as long as an electrical outlet is nearby.

How does TOTO’s self-cleaning wand and CLEAN RESIN® system work together?

The KS5 uses a self-cleaning wand that automatically rinses itself before and after every use to help prevent buildup on the spray nozzle. At the same time, CLEAN RESIN® technology is built into key contact surfaces like the seat and wand housing to resist waste and mineral adhesion. Together, these systems reduce manual cleaning, improve hygiene consistency, and help maintain a cleaner surface over time with minimal maintenance
