I bought a bidet attachment in early 2024 as a joke. My friend had been evangelizing about his for months — “it changes your life,” “you will never go back,” the whole thing. I bought the cheapest one on Amazon, a $29 model with a single knob, just to get him to stop talking about it.

Within a week I had ordered two more for the other bathrooms. I am now the annoying friend who evangelizes about bidets. Here is why this thirty-dollar piece of plastic is genuinely the best value purchase I have made in years, and what to look for when buying one.

What you actually get for $30

A bidet attachment is not a full bidet toilet. It is a slim unit that mounts between your toilet seat and the bowl, connected to the water supply line behind the toilet with a T-adapter. When you turn the knob, a nozzle extends and sprays water. That is it.

Installation took me about fifteen minutes with no plumbing experience. The kit includes everything you need: the bidet unit, the T-adapter, a flexible hose, rubber washers, and instructions. You need a wrench and a screwdriver. You do not need to drill anything, modify the toilet, or call a plumber. It connects to the same water line that fills your toilet tank.

The things nobody tells you before you buy one

The water is cold. If you spend $30, you get cold water. If you spend $200+, you get heated water and a heated seat and a warm air dryer and probably a remote control. But the cold water stops being shocking after about three uses. Your body adjusts. Now I barely notice it.

You use way less toilet paper. I went from buying a 24-pack of toilet paper every six weeks to every four months. The bidet does most of the cleaning; you use a few squares to pat dry. Over a year, the toilet paper savings alone pay for the bidet two or three times over.

Guests will be confused. I have had three different people come out of my bathroom and ask, “What is that thing attached to your toilet?” And then they try it, and two of those three people bought their own. The third person thought it was weird and I respect their wrong opinion.

Which one to buy

The Luxe Bidet Neo 120 is the one I bought. It has a single knob that controls water pressure. That is the only feature. No temperature control, no front/rear spray selection, no self-cleaning nozzle — just a knob. And it works perfectly.

If you want to spend a bit more, the Neo 185 ($45) adds a second nozzle for a front wash and has a self-cleaning function. The Neo 320 ($65) adds hot water by connecting to your sink’s hot water line. That requires your sink to be close to your toilet and a longer installation.

For most people, the basic $30 model is enough. You are not buying a luxury experience. You are buying a device that cleans you with water instead of smearing things around with dry paper. It is a functional improvement, not a spa upgrade.
