Humans have been cleaning their bodies with water for thousands of years. Even if you don’t know how to wash your undercarriage in your culture, it is a common practice and necessary. You are fortunate if that is why you are here.

Modern toilets often have hoses that can be used to attach a bidet. Many toilets may not have hoses to install a bidet.


Yes, you can. It isn’t as easy as it looks. It can be difficult to mount a bidet in some toilets, but it is possible with others.

Most toilets don’t have a bidet option. You will need to make an extra effort if your bathroom is older than you think and doesn’t have a bidet. However, most toilets can be fitted with a bidet attachment.

Installing Bidet On Two-Piece Toilets

Two-piece toilets work well for most bidets. Two-piece toilets are designed with separate basins and tanks. The tanks and basins are placed in front of each other.

It is easy to connect your bidet to the toilet. You can install any heated bidet attachment, or toilet spray yourself.

A two-piece toilet has the advantage of being able to locate the filling valve quickly. The fill-in valve connects to the inlet of water. The valve must connect most bidets so that water can be rerouted into them.

Two-piece toilets are also very predictable. It is likely that your bathroom has a two-piece toilet. Because of their popularity, it is easy to understand the structure and determine the best place to install the bidet.

Installing Bidet On Conventional One-Piece Toilets

One-piece toilets are bidet-friendly Most one-piece toilets can be bidet-friendly. Semi-bidet-friendly is the term we use to describe it. It has one unit, with just the basin and bowl. The mainframe is attached directly to the tank. You can still use a bidet to install one-piece toilets even after removing the mainframe.

The fill-in valve is visible on most one-piece toilets. You can usually find an alternate way, even if it is difficult to reach. The problem comes when there is less space between your valve and the wall. This problem is more apparent if the toilet has a flatback.

A bidet will almost always come with a T-connector to connect to the valve. You won’t be capable of properly installing it if there isn’t enough space between the valve & the wall.

Are Bidets possible on tankless toilets?

When installing a bidet, tankless toilets (or flushometers) are a challenge. This is because toilets don’t have a tank. It is essential that the building has adequate plumbing to supply water directly into the basin. You cannot access water unless the toilet is flushed and you can see it swirling in the bowl.

You don’t have a tank so you can’t attach the t connector to the fill-in device. This creates the problem. Alternative methods are the only way to get out of this mess. To install bidets in tankless toilets, you will need to have special equipment.

To connect the water supply, you may need to drill into the wall. These methods are only applicable to non-electric or handheld bidets.


Toilet paper doesn’t always clean your toilet. Even though the bidet was originally developed in Europe, it is now popular in Western countries. You will find yourself at crossroads if you choose to buy a bidet in your home.

There are many kinds of bidets on the market. The type of toilet you have will determine which bidet you choose. If you are a frequent traveler and want to be super clean, you can get travel or portable toilet.

Electric Bidet

There are two types of electric bidets: the electric bidet combination and the electric bidet seat. The electric bidet toilet seat is for toilets without a bidet option. You manually place the toilet seat on top of the toilet. For people with mobility problems, electric seats can be helpful.

The electric bidet combination is a toilet that includes a bidet. You don’t need to buy one separately. If you’re remodeling your bathroom or changing the toilet, it will be a better option.

Ceramic or Standalone Bidets

These look most like traditional bidets you will find in many European homes. Because they are separate from the toilet, ceramic bidets can also be used as standalone bidets. The bidets hang from the wall and look more like a toilet. People without a bidet culture often confuse it with one.

You can only use a standalone model to clean your rear area. After you’re done, you can go back and clean. Many standalone models have modern technology, including water temperature control. These models are best if you want something more traditional and have enough space in your bathroom.

Handheld Bidet

Handheld bidets can be a good compromise if you don’t want things to get too complicated. They are often mistaken for bar showers, even though they look very similar. Bidet sprays or handheld bidets can be hoses that have one end connected to the plumbing and the other attached to a sprayer.

The toilet bidet spray can be a great option for those with limited flexibility. This sprayer allows you to control the water flow and pressure more easily. Sprayers are also cheaper than other bidet options. Many sprayers come with double pins. This allows you to choose the temperature of the water.

Portable Bidets

Bidets can be found in Asian and European countries. It can be difficult to find bidets at hotels and other locations in countries such as the United States.

You can take your portable bidet anywhere you want. They can be easily packed in a backpack and taken on a trip. They are also the most affordable option on the market. However, they do not offer the same technical features as other types.
