Key takeaways

  • Bidets use a gentle water stream for a more hygienic clean than toilet paper alone.
  • Washing can be more comfortable and less irritating, especially for those with sensitive skin or hemorrhoids.
  • Bidets are easy to keep clean and often include self-cleaning features.
  • Bidets use the same fresh tap water as your sink (never from the toilet tank or bowl).
  • Bidets reduce toilet paper use, and models with a warm air dryer can help eliminate it almost entirely.


You keep hearing about bidets—which isn't surprising, because they're more popular than ever. But you can't help but wonder: do they actually get you clean?

Do bidets clean better than toilet paper?

Bidets wash you using a gentle stream of water, so they’re naturally more effective at getting you clean compared to toilet paper. Think about it like this: if you don’t expect your hands to be clean after wiping with paper towels, why would toilet paper is enough for down below? Water is simply more hygienic for washing, which is why bidets are so effective.
Bidets are also gentler on the skin than toilet paper, and can help reduce irritation or alleviate discomfort from medical conditions like hemorrhoids .

Is it easy to keep a bidet clean?

Just like any bathroom fixture, bidets benefit from regular cleaning. By keeping up on regular maintenance, you can reduce any buildup, while ensuring your bidet performs at its best.
Many modern bidets have features like retractable stainless steel nozzles, nozzle guards, and self-rinsing functions to regularly rinse off any dirt or buildup. Still, it’s never a bad idea to deep clean your bidet every now and then.
When it's time for a more thorough cleaning, use a sponge and a mild cleaning spray to wipe clean. (If you have an electronic bidet, make sure you unplug it first.) As with other bathroom surfaces, you may opt to wear cleaning gloves to avoid contaminating your hands.

How do I know that the water in my bidet is clean?

A bidet doesn’t pull water that you wash with from the toilet bowl or tank. Instead, it uses the water from your home's incoming fresh water supply—also known as "tap water." Tap water goes through a treatment process that makes it safe enough to drink and clean with by the time it gets to your home.
So how does this clean tap water get to your bidet? All bidets come with a T-valve that attaches to the toilet’s fill valve, usually below the tank. This valve diverts the clean tap water in two separate directions—one towards the toilet’s fill valve to fill the tank, and the other towards the bidet through an included bidet hose. This keeps the water that the bidet uses from mixing with the water in your toilet tank.

Do you still need to wipe after using a bidet?

Once you find a bidet that works for you, you can experiment with different water pressures and washing duration to see what gets you feeling your cleanest. [MJ7.1]A thorough bidet wash ensures there's nothing left behind but water—so there's no need to use toilet paper for additional cleaning.

After you wash with your bidet, you can pat dry with a small amount of toilet paper. Or you can help the planet even more by using an eco-friendly, machine-washable bidet towel. Another way to avoid T.P. completely is to get a bidet toilet seat with a warm air dryer, a feature that delivers a gentle, soothing air dry cycle after your wash.
