The TOTO sw3446#01 is an elongated electronic bidet toilet seat designed for residential bathroom installations where hygiene, comfort, and water efficiency are priorities. It uses instantaneous water heating to deliver a continuous warm water wash without a storage tank, eliminating wait time for warm water. The seat features PREMIST, which wets the bowl surface before each use to aid waste removal, and EWATER+ wand self-cleaning, which electrolyzes water into a cleansing compound applied to the inside and outside of the wand before and after every use. Installation and mounting hardware are included. Plumbers and skilled DIYers typically handle the install.
This bidet seat fits elongated toilet bowls in standard residential applications. It is suited for single-family homes, accessible bathrooms, and any setting where reduced toilet paper use or enhanced personal hygiene is a requirement. The included wireless remote keeps controls off the seat itself, which simplifies the user interface and reduces clutter on the fixture. The unit also features a soft-close seat, a night light, and an air dryer, making it a full-function replacement for a standard toilet seat.
Designed as a replacement or upgrade bidet seat for elongated toilet bowls in residential installations. Verify elongated bowl fitment against existing fixture dimensions before ordering.
Installation is typically performed by a licensed plumber or a qualified DIYer with basic plumbing experience. Shut off the water supply to the toilet before beginning any work. The seat connects to a standard water supply line, and an accessible GFCI-protected electrical outlet is required near the fixture per NEC guidelines. Do not overtighten supply connections, and confirm all fittings are leak-free before restoring water supply.
