This distance can vary depending on the type of toilet you have and the specific plumbing in your home, but there are a few general guidelines that can help you get started.

In this article, we’ll discuss the different factors that affect the distance between a toilet drain and the wall, and we’ll provide some specific recommendations for common toilet types. We’ll also cover some of the potential problems that can occur if you don’t leave enough space for your toilet drain.

So whether you’re planning a new bathroom or remodeling an existing one, read on to learn more about how far your toilet drain should be from the wall!

Distance From Wall Minimum Maximum
Center of the Bowl 12 inches 18 inches
Center of the Flange 10 inches 15 inches

Factors Affecting Toilet Drain Location

The distance from the center of the toilet to the wall is one of the most important factors to consider when installing a toilet. This distance will affect the type of toilet you can use, the size of the toilet, and the location of the water supply and sewer lines.

Distance from the Center of the Toilet to the Wall

The standard distance from the center of the toilet to the wall is 12 inches. However, there are some exceptions to this rule. If you have a small bathroom, you may need to install a toilet with a shorter distance from the center to the wall. Conversely, if you have a large bathroom, you may be able to install a toilet with a longer distance from the center to the wall.

The type of toilet you choose will also affect the distance from the center to the wall. Flush valve toilets require more space than gravity toilets. This is because flush valve toilets have a larger trapway, which is the opening in the bottom of the toilet that allows water to flow out of the toilet bowl. Gravity toilets have a smaller trapway, so they can be installed closer to the wall.

Type of Toilet (Flush Valve or Gravity)

There are two main types of toilets: flush valve toilets and gravity toilets. Flush valve toilets are more common in new homes. They are more efficient than gravity toilets and they use less water. Gravity toilets are older technology and they are not as efficient as flush valve toilets. However, gravity toilets are less expensive than flush valve toilets.

Size of the Toilet

The size of the toilet will also affect the distance from the center to the wall. Standard toilets are 17 inches wide and 28 inches deep. However, there are also compact toilets that are smaller than standard toilets. Compact toilets are a good option for small bathrooms.

Location of the Water Supply Line

The location of the water supply line will also affect the distance from the center to the wall. The water supply line is usually located on the back of the toilet. If the water supply line is located close to the wall, you will be able to install the toilet closer to the wall. Conversely, if the water supply line is located far from the wall, you will need to install the toilet further from the wall.

Location of the Sewer Line

The location of the sewer line will also affect the distance from the center to the wall. The sewer line is usually located on the floor. If the sewer line is located close to the wall, you will be able to install the toilet closer to the wall. Conversely, if the sewer line is located far from the wall, you will need to install the toilet further from the wall.

How to Measure for a Toilet Drain

To measure for a toilet drain, you will need to measure the following:

  • The distance from the center of the toilet to the wall
  • The height of the toilet
  • The distance from the toilet to the water supply line
  • The distance from the toilet to the sewer line

Measure the Distance from the Center of the Toilet to the Wall

Measure the Height of the Toilet

To measure the height of the toilet, you will need to:

1. Place the toilet in the desired location.
2. Stand in front of the toilet and look at the top of the toilet bowl.
3. Use a tape measure to measure the distance from the floor to the top of the toilet bowl.

Measure the Distance from the Toilet to the Water Supply Line

To measure the distance from the toilet to the water supply line, you will need to:

1. Locate the water supply line.
2. Measure the distance from the toilet to the water supply line.

How Far From The Wall Should A Toilet Drain Be?

The distance between a toilet drain and the wall depends on the type of toilet you have. For a standard toilet, the drain should be about 12 inches from the wall. For a high-efficiency toilet, the drain should be about 10 inches from the wall.

It is important to measure the distance from the wall to the center of the toilet drain before you begin the installation process.

What is the minimum distance from the wall that a toilet drain can be?

The minimum distance from the wall that a toilet drain can be is 10 inches. This is because the toilet flange, which is the part of the toilet that connects to the drainpipe, needs to be at least 10 inches above the finished floor.

What is the maximum distance from the wall that a toilet drain can be?

How do I adjust the distance from the wall of my toilet drain?

If you need to adjust the distance from the wall of your toilet drain, you can do so by using a toilet flange extender.
