Named FORBES 2026 BEST VALUE BIDET ATTACHMENT, The Bio Bidet SlimEdge bidet attachment is a budget-friendly, non-electric bidet that installs under your existing toilet seat for a cleaner, fresher alternative to toilet paper. No batteries, no outlet, and no plumber required.

• Wash Your Way™: Dual retractable nozzles give you separate posterior and feminine washes, so everyone in the household gets a clean that suits them.
• Comfort at your fingertips: The side-mounted comfort control knob adjusts water pressure from a gentle rinse to a stronger clean.
• Works without power: No electricity or batteries required, so you don't need an outlet near the toilet.
• Slim, low-profile design: It sits neatly under your seat for a clean, subtle look.
• Built to last: Durable brass installation parts and a braided water supply hose.
• Simple DIY install: Follow the step-by-step installation manual, and our U.S.-based support team is here to help if you need it.

A Bio Bidet fan favorite, every SlimEdge comes with a 1-year limited warranty and customer support by phone and email. See how it compares to our other bidet attachments and seats in our bidet comparison chart.
