How Far Should a Toilet Be from the Wall? (Explained)

The placement of the toilet is crucial to your comfort as well as your sanitation. You can affect your privacy and the way you use the toilet by the distance between the toilet and the wall.

Making sure you take all the necessary precautions to ensure optimal sanitation begins with understanding the distance between the toilet and the wall.

How far should a toilet be from the wall?

The ideal distance between a toilet and a wall is one foot (12 inches). This ensures that you have sufficient space to both access and use the toilet, as well as maintain the privacy of your privacy. It is ideal to maintain a distance of 12 inches from the back wall and 15 inches from the side wall.

You patch your leaks by absorbing and holding liquid when you go to the toilet. The Patch may leak if it is too close to a surface that can leak (a wall or floor).

Imagine it sitting directly on top of a porcelain sink. Once liquid seeps out from underneath the patch, it continues to run down into the drain.

Dripping continuously makes noise and pollutes water with wastes already pickled in solids from liberally pouring urine analysis solution onto floors at night.

When a toilet is placed far from a wall, there is less chance that your privacy will be invaded, as well as less noise and waste produced when using the toilet.

By keeping the toilet at least 12 inches from the wall, easy access to the toilet is made possible, and the bathroom is kept cleaner. It is more likely that liquid will seep from underneath a patch and drip onto the floor if the toilet is close to the wall.

Toilets placed too close to walls can also cause drainage problems and contamination of the water supply.

Back wall:

There should be a distance of 12 inches between the back wall and the toilet. As the wall can cause leaks, the toilet should be placed a few inches away from the wall to avoid direct contact.

The wall should not be placed too far from the toilet, since this could create a barrier between the user and the toilet.


The distance between the toilet and the side wall should be 15 inches. Ensure that you have sufficient space while also protecting your privacy when using the toilet.

There should not be a distance between the side wall and the toilet, as this could create an obstruction.

Are all toilets the same distance from the wall?

There are many different types of toilets produced by different manufacturers, and each one has a different dimension. It is therefore important to note that not all toilets are located at the same distance from the wall.

It is generally accepted that toilets are constructed with a bowl at the front and a wall or side wall behind it.

Whenever you use the bathroom, you need to keep your distance from the wall to the center of the bowl because that is where the liquid waste accumulates when you use the bathroom.

In most toilets, it is recommended to have a minimum distance of 15 inches from the wall on the side.

It is not permissible to install any toilet less than 15 inches from the wall. There should, however, be at least 30 inches between the bidet and the toilet when there is a bidet next to it.

Toilet distance from wall ADA

ADA requires public accommodations, such as restaurants, movie theaters, and convenience stores, to provide disabled customers with toilet facilities.

ADA toilets must be 54 inches from the front wall, 17 inches or 19 inches from the floor to the top of the seat, and 16 inches or 18 inches from the center of the bowl to both sides of the wall.

ADA measures the maximum toilet width that can be positioned within +/- 4 inches of the nearest side or top rail, whichever is wider.

The measurement does not include an accessible path leading from either side of the toilet to a doorway leading to a bathroom without any interior walls separating it from other public areas.

Public restrooms typically have a beveled edge on the wall to help wheelchair users enter and exit their restrooms.

This is different from the ADA toilet specifications found in a home. If you are planning to install a toilet in your own home, you should not worry about whether the edge is beveled or not.

5 factors that affect the toilet distance from the wall

Any bathroom designer must take into consideration the distance of the toilet from the wall. From the height of the seat to the distance between toilets and walls, everything is taken into account. Five factors affect the distance between the toilet and the wall:

The Height of the Sea Fixtures:

Depending on the height of sea fixtures, such as sinks and toilets, the toilet distance from the wall may vary. In this case, a low-set sink will be closer to the ground than a high-set one, resulting in a shorter distance between them.

The Location of Doorways and Windows:

Doorways and windows near the toilets may also affect how far they are from the wall if they are located close to them. When there is an opening near one side of a toilet but not on its opposite side, the toilet would be closer to the wall.

The Width of the Bathroom:

The width of a bathroom can also affect the distance between toilets and walls. To make space for everyone in the bathroom, if there is not much space between a toilet and the wall, the toilet may need to be moved further away.

The Height and Width of Seats:

Many people prefer seats as close as possible to toilets so they don’t have to get up from their seats. However, there is no universal rule for how close seats should be to toilets. Some people might find it annoying if the seats are too far from each other.

How the Toilet Is Arranged:

To make more space, a toilet may need to be moved closer to a wall if it is located in a small area. Additionally, if the toilet is not arranged evenly along the wall, it may need to be rearranged to make it more convenient for everyone

How to install a toilet at a proper distance from the wall?

It is important to take into account the distance between a toilet and a wall when installing one.

A close distance will cause water to run back onto the floor and cause your home to flood.  The following are guidelines for installing a toilet at the right distance from the wall:

Measure the distance from the wall to the toilet:

The first step is to measure the distance between the wall and the toilet. This will help you figure out how far away the drain should be situated so that water will not run back onto the floor when it is running.

Ensure 12-inch distance from the back wall:

Maintain a distance of at least 12 inches from the back wall. The drainage system will need to be properly designed to ensure proper operation. Additionally, a toilet seat must be placed slightly higher than the wall for the toilet to have enough room.

Ensure 15 inches distance from the side wall:

Ensure a minimum distance of 15 inches from the side wall. It will be necessary to do this to prevent water from running onto the floor or furniture from the toilet. To prevent the toilet from touching the wall, the toilet should not be placed too close to it.

Align the toilet with the wall and mark the location:

Mark the spot where you will make a hole to install bolts or screws after aligning the toilet with the wall.

Here you can connect the water supply line to your fixture’s plumbing. Drill a hole into your newly marked spot so that you can screw in your pipe from below.

Install a toilet seat:

The last step is to install the toilet seat on the toilet. Make sure that the bolts or screws on the wall are tightened enough so that the toilet is not able to move from its location once it has been installed.

As an additional point, the toilet should be positioned such that the water from the tank will fall into the bowl and not onto the ground when the bowl is empty.

Final Thoughts

Ideally, the distance between the side wall and the toilet should be 15 inches. Make sure the back wall is 12 inches away from the front wall. Dimensions, wall thickness, and mounting brackets vary by manufacturer. ADA requires toilets to be 54 inches from the front wall and 17″-19″ from the ground.
