Bidets are getting a lot of attention these days, and for good reason. For starters, modern bidets are easy to install on your existing toilet. Users are appreciating the fact that washing with water is more refreshing and hygienic compared to wiping with toilet paper alone.

If you're ready to make the switch, welcome to the bidet club—and a whole new world of freshness. If you’re excited about the experience, but aren’t sure if you can install one, we've got the bidet for you: it's called a bidet attachment.

These are one of the most popular types of bidet add-ons for your toilet. People love them because they’re an easy, straightforward way to turn your toilet into a bidet without a complicated setup or installing a separate fixture.


What is a bidet attachment?

A bidet attachment is a bathroom appliance that mounts between your toilet seat and bowl. A low price point , easy installation, and gentle, cool water washes make bidet attachments a great choice for anyone—especially first-time bidet owners.

Bidet attachments have a side arm that sits flush with your toilet seat. From there, you’ll be able to control your bidet’s water pressure, as well as the water temperature if you choose a bidet that can connect to warm water.

Bidet attachments don’t need electricity and are powered purely by the clean water from your toilet. They also come with simple plumbing parts that divert clean water from your toilet, so you won’t have to make any extra trips to the hardware store.

Do bidet attachments come with everything you need to set up?

Yes, Brondell bidet attachments come with all of the parts needed to install. You may need some standard tools to get the job done, like a screwdriver to remove your toilet seat and a wrench to loosen plumbing connections. But other than that, you’re good to go. There are a lot of different bidet attachments out there, but the parts they come with are more or less the same, though what these parts are made of can vary.
Here's a quick breakdown of the most common parts you'll find when you open your bidet:

  • A T-Valve for diverting water from the toilet’s cold water supply. This makes sure that there’s water going to both your toilet tank and the bidet.
  • A bidet hose that connects the T-Valve to your bidet.
  • Some bidets also come with hot water tubing and a separate T-Valve to draw water from your sink’s hot water supply.


Hardware components for bidet installation, including a T-valve with washers, a stainless steel bidet hose, hot water tubing coil, and hot water T-valve.

What features do bidet attachments come with?

Some of the most popular features you’ll see on bidet attachments are:


Bidets may not come with luxurious add-ons, but their simplicity is exactly why people love them. Bidet attachments are designed to keep you clean down there—pure and simple. They give you the wash you need while keeping their components clean, and they do that job well.

Those are the most common features, but not the only ones. If you want to wash with warm water, you’ll want a bidet attachment that includes the plumbing parts needed to hook up to your bathroom sink’s hot water line. Keep an eye out for other features too, including bidets with recycled components for even more sustainability, left-handed controls, and more.

Is it easy to install a bidet attachment?

Adding a bidet attachment to your toilet is easy, and you won't need a plumber or plumbing knowledge to do it. All of these steps should take about 30 minutes or less, and don’t require any major overhauls to your bathroom.
Setting up is a breeze—here are the basic steps:

  • turn off your toilet’s main water supply
  • remove your toilet seat
  • install the T-Valve between the cold water supply and toilet tank
  • connect your bidet to the T-Valve with the bidet hose
  • reattach the toilet seat
  • turn the water supply back on and check for leaks

Bidet attachments are also easy to remove, too. If you’re a renter, adding on a bidet attachment is a great option—they're easy to detach and take with you when it’s time to move.
