How to Find a Bidet That Fits Your Toilet

Will a Bidet Fit Your Toilet

A bidet is a wonderful way to clean off and freshen up after using the bathroom. Some bathrooms have a separate bidet installed beside the toilet. But by simply fitting a bidet attachment to your toilet, you can experience the joys without the expense.

Bidet attachments are available to fit most toilet sizes and shapes. Some attachments are universal, while others are made for use on specific toilet designs. While most bidet attachments will fit a two-piece toilet comfortably, finding the correct fit for a one-piece toilet is more challenging.  

Read on to find out if you can fit a bidet attachment to your toilet at home.


Bidet vs. Bidet Attachment vs Bidet Toilet Seat

Let’s take a look at the difference between a bidet and a bidet attachment:


What Is a Bidet?

What is a bidet?

A stand-alone bidet is a bathroom fixture installed in a bathroom alongside a toilet, used as a hands-free means of washing one’s tushy after completing the necessary ablutions. A bidet effectively eliminates the need for toilet paper.

Although a bidet might look like a toilet, it provides an altogether different function (although complementary!). 

Here is the basic order of operations:

  1.   Use the toilet to do your business.
  2.   Scootch over to the next bathroom fixture and use the bidet to clean up.

The most important function of the bidet is to wash and dry the outside of your tushy. This is achieved by a stream of clean water shooting up to your nether regions.

If you have the correct attachments, you can warm up the water which is so much nicer than cold water.

After you have cleaned your areas, dry off using the built-in drier that comes with many units.  

For many people worldwide, a bidet is the easiest and most hygienic way to clean up after using the toilet. A bidet is gentler on your skin than toilet paper and is definitely more comfortable to use if you have fissures or hemorrhoids.


What Is a Bidet Attachment?

A bidet attachment is a small control panel with a built-in sprayer nozel that fits onto the back and side of the existing toilet bowl. The water hoses are connected to the plumbing. 

A bidet attachment can be much cheaper than buying a whole new bathroom fixture and you can often install it yourself. If you have a small bathroom, then this is a great option to save on space. 

But many people prefer using a bidet attachment simply because they don’t have to move from one place to the other to complete the cleaning process.


What Is a Bidet Toilet Seat?

If a bidet attachment is not an option, try the bidet toilet seat. Simply replace your existing toilet seat with a bidet seat.

A bidet toilet seat offers the same functions like any other bidet but replaces the existing toilet seat rather than being an additional accessory.

The attachment and the toilet seat are great options for those who would prefer to do all their business on the same toilet! 


Will a Bidet Attachment Fit My Toilet?

A bidet attachment is designed to fit one-piece and two-piece toilet models with ease – the trick is to find the correct model for your toilet style.


Bidet Attachment for Two-Piece Toilet

Height of Bathroom Sconces

A two-piece toilet is generally more bidet-friendly simply because it has a separate tank and bowl. The tank is attached to the bowl at the back of the basin, leaving plenty of space for the bidet attachment and space for the installer to work in.


Bidet Attachment for One-Piece Toilet

A one-piece toilet is flatter in the back. This means less space between the wall and the back of the toilet and less space for installing the bidet connectors.

Ultra-modern bathroom toilets are generally one-piece designs and are not built using standard dimensions as regular toilets. A French curve design is a particularly difficult shape to fit a bidet, but a handheld bidet can safely be used on this toilet type.



Bidet Attachment for Tankless Toilets

Tankless toilets and toilets with hidden cisterns do pose a challenge when it comes to the bidet attachments, but, as with all toilets, there will be an attachment to fit! 

If you’re thinking of purchasing a tankless toilet, read my post WIll Your Go Tankless? Toilet Pros and Cons to learn if a tankless toilet is the right choice for you.

Now, let’s have a look at the advantages and disadvantages of these toilet types for bidet attachments:


One-Piece- Handheld sprayers can be used on this toilet type
- Bidet attachments can be used on this toilet type
- Conversion kits are readily available for bidet attachments
- The fill valve extends out from the toilet instead of from the bottom of the tank
- The back of the toilet is flat, leaving less space for installations
- The area around the back could be too wide, limiting your choice of bidets
- Standard mounting hardware could be incompatible
- The bolt holes could be too far apart, non-standard
- Some toilet-seat type bidets might not fit
Two-Piece- Most bidet attachment types can be used on this toilet type
- These toilets have traditional dimensions for universal fit
- Visible trapways and skirted toilets allow for easier installations
- Certain bidet models might only fit on round or elongated bowls
- The fill valve on a 2-piece toilet extends from the bottom of the tank and could be in hard-to-reach spaces
French curve- Handheld sprayers are the best to use on these toilet types- A sloping tank down towards the seat with a rounded area at the back of the toilet can make it difficult to install a bidet attachment.
- Incompatible with toilet seat bidets
Tankless and hidden tanks- Handheld sprayers are the best to use on these toilet types- Bidet attachments are not usually installed on these types of toilets
- Water is not easily accessible, requiring plumbing or remodeling to fit the connectors to the bidet attachment


Can You Put a Bidet Attachment on Any Toilet

Water Saving Toilet

Traditionally there are two general types of toilet bowl shapes – one is round, and the other is elongated.  (Learn the differences between thee toilet seat shapes by reading my post, Round or Elongated Toilet Seat for a Happy Bottom?)

Unless you own an ultra-modern square, boxy toilet, your toilet should fall into one of these two categories.

These shapes are generally standardized sizes with traditional dimensions and the same bolt hole widths, making it easy for bidet manufacturers to design bidets to fit most toilet types.

Measure the toilet to confirm which size and shape you have to determine the correct bidet attachment for your toilet:


Toilet ShapeLength (Back to front)Midpoint between boltholesDistance between midpoint and tank
Round19.5” (45.5cm)5.5 – 7.5” (14 - 19cm)3” (7.6cm)
Elongated20.5”(52cm)5.5 – 7.5” (14 - 19cm)2” (5cm)
