When roughing in a toilet, the minimum rough-in distance is measured from the wall behind the toilet to the center of the waste outlet, which is typically 12 inches. The waste outlet is behind the toilet on the floor and is the connection where you will attach the toilet drain.
Once installed, the toilet should be located so that the rim of the bowl clears the wall by a foot or more on each side of the bowl. If extra space is available, it is recommended to have at least 18 inches of space from the wall behind the toilet to the drain outlet, to allow for more comfortable installation of the toilet.
What is a standard rough in distance for a toilet?
The standard rough in distance for a toilet typically refers to the distance between the wall at the back of the toilet and the center of the toilet’s hold-down bolts. Generally, the industry standard is 12 inches, however, there are different sized fixtures with different rough in values.
For example, a compact tank may require a 10-inch rough in while some older toilets may require as much as 14 inches. When in doubt, measure the old toilet before purchasing a new one. It is also important to take into consideration the location of any pipes or other items that could obstruct the toilet when determining the rough in size.
What does 12-inch rough in mean when installing a toilet?
A 12-inch rough in is a measurement taken from the wall behind the toilet to the center of the toilet outlet at the floor. In other words, the distance from the center of the waste pipe to the center of the bolt holes on the base of the toilet.
It is important to note the rough in measurement when considering the replacement of a toilet or the installation of a new one. A standard rough in is 12-inches but it is possible to find toilets with a 10- or 14-inch rough in measurements.
You make sure you measure the distance accurately when checking for a new toilet. If the wrong size toilet is purchased, it will not fit properly and may be too close to the wall or too far away.
How do I know if I need a 10 inch or 12-inch rough in toilet?
The rough in of a toilet is the measurement from the wall behind the toilet to the center of the floor drain. To determine which size toilet you need, measure the distance between the wall and the center of the floor drain and compare it to the two standard sizes of 10 inch or 12 inch.
If your measurement is exactly 10 inches or 12 inches, then you need a 10 inch or 12 inch rough in toilet, respectively. If your measurement falls between 10 and 12 inches, it’s best to measure twice to ensure accuracy.
If your measurement is 10. 5 – 11. 5 inches then you need an elongated 10 inch rough in toilet, which is often referred to as a 10. 5 inch rough in toilet. It might be a good idea to confirm your measurements with a plumber or toilet specialist in order to ensure the proper fit for your toilet.
What’s the difference between a 10 inch rough in a 12-inch rough in toilet?
The difference between a 10 inch rough in and a 12-inch rough in toilet is the distance between the back of the toilet bowl and the wall (or other surface) behind it. When measuring the distance from the back of the bowl to the wall, a 10 inch rough in toilet has a distance of 10 inches, whereas a 12 inch rough in toilet has a distance of 12 inches.
This important measure needs to be taken into consideration when looking at different types of toilets and finding one that is suitable for your bathroom. When the right toilet is chosen, the 10 inch or 12 inch rough in will determine the placement of the toilet’s bolt holes that secure the toilet to the floor.
If the rough in measurement is off, it can be difficult to have a properly fitting toilet.
Can you replace a 12-inch rough in toilet with a 10-inch rough in?
The answer is yes, you can replace a 12-inch rough in toilet with a 10-inch rough in. The key is to make sure that the new toilet will fit in the space from the floor to the wall and that the drain opening is the correct size.
If you check the dimensions of the new toilet, you should be able to see if it will fit and if the drain opening is the proper size, it can be done.
When installing a new toilet, both the water supply and the drainpipe should be verified for the necessary clearance relative to the base. Some toilets can have a base slightly larger than 12 inches, so careful measurements should be made and verified for the new toilet installation.
It is also important to check the bolt placement and the supply line placement during the installation of the new toilet as well. Most plumbing codes require a 12-inch minimum clearance behind a toilet base.
If the 10-inch rough-in toilet is installed with a 12-inch rough-in, you may be limited in the length of the water supply line and the width of the flange wax ring.
Finally, depending on the model you choose, some toilets come with a 10-inch rough-in, but the base requires more than 12 inches of clearance apart from the installed floor and wall. Make sure to compare the exact measurements of your old toilet with the new toilet before making a purchase.
Does a 10 rough in toilet save space?
Yes, a 10″ rough-in toilet does save space compared to a 12″ rough-in toilet, which is the standard size. This is because the 10″ rough-in puts the waste outlet farther back in the wall. This design allows for a smaller bowl, but the space that is saved is usually minimal.
Keep in mind, however, that a 10″ rough-in toilet may make it difficult to install a flapper-style toilet, since the chain and handle arm may not be long enough to reach the bottom of the flush valve.
For this reason, you should always check that the flapper-style toilet you choose is compatible with your 10″ rough-in before purchasing and beginning installation.
