Toto Sw344612 Elongated Bidet Toilet Seat

Product Description

The TOTO sw3446#12 is an elongated bidet toilet seat in the Washlet S5 series, designed for residential bathroom installation by licensed plumbers or qualified trades. The unit features a tankless profile that is 19% slimmer than previous designs, reducing overall material use without sacrificing function. It delivers endless warm water for the wash function, a heated seat, and a warm air dryer. PREMIST technology wets the bowl surface before each use to help waste from adhering, and the EWATER+ system sanitizes the wand after use. This seat is intended for permanent installation on elongated toilet bowls with a standard water supply connection.

The sw3446#12 is suited for residential bathroom settings where hygiene, comfort, and water efficiency are priorities. The seat supports personalized settings for up to four individual users via an included remote control. A built-in nightlight provides low-light visibility without requiring a separate fixture. The warm air dryer and adjustable heated seat make it suitable for year-round use in climate-controlled bathrooms.

Installation Notes

Installation is typically performed by a licensed plumber. Before beginning, shut off the water supply valve at the toilet and relieve line pressure. The seat connects to a standard low-pressure water supply line and requires a grounded electrical outlet near the toilet — consult NEC guidelines for bathroom receptacle placement and GFCI requirements. Do not overtighten mounting hardware on the toilet bowl; follow the manufacturer's written installation instructions for torque guidance.
