Bidet comfort, no outlet required. The new BB-300 is a non-electric bidet seat with front and rear washes, adjustable water pressure, and a built-in Child Lock, all in a slim seat that sits just 2.7 inches tall. It's designed for easy DIY installation, with no plumber needed.
- Front and rear washes: Dual retractable nozzles offer a front or rear wash, so the whole family gets a clean that suits them.
- One simple control: Turn the control knob forward or backward to choose your wash and set the water pressure.
- Built-in Child Lock: Push the knob in to unlock it before each use, which helps prevent accidental sprays from curious kids and clumsy pets.
- No power needed: The BB-300 connects to your toilet's fresh water supply and works without electricity, so you don't need an outlet near the toilet.
- Slim and quiet: The seat sits just 2.7 inches tall, and the slow-closing seat and lid lower gently with no slamming.
- Stay·Tite® fastening: Keeps your seat secure and wiggle-free, use after use.
Will it fit? The BB-300 is made for elongated toilets. Measure from the center of the seat bolt holes to the front edge of the bowl; elongated toilets measure about 18.5 inches. See our compatibility guide to confirm your toilet's shape and style.
