Non-electric bidet attachments are the easiest way to add bidet functionality to your existing toilet. Most bidet attachments, like the Bio Bidet BB-70, are simply installed underneath your existing toilet seat with no need for an electrical outlet. They hookup to the nearest water source and provide fresh water cleansing powered by water pressure. Some non-electric bidets, like the Alpha ONE V2 replace your toilet seat altogether and provide a more integrated bidet solution.
Some advantages of non-electric bidet attachments include affordability, ease of installation, the ability to keep your current toilet seat, and higher water pressure and volume. Since they are powered directly by water pressure, non-electric bidets are able to produce much higher water pressure and volume than their electronic counterparts. However, since no electricity in involved, convenience features like heated seats and dryers are not available..
