## How do I know if my toilet is a 10 or 12 rough?

If you’re planning on replacing an old toilet, it’s important to know the rough-in size. This is the distance from the center of the capped bolts on the bottom of the toilet to the wall (not the baseboard). As a guideline, there should be 24 inches of clearance from the wall facing the bowl and 15 inches on each side. If your measurements are between 115 and 125 inches, it is a 12-inch rough-in.

The rough-in is the distance from the wall to the center of the drain pipe. The standard rough-in for a toilet is 10 inches, but you can install a toilet designed for a 10-inch rough-in into a space that has a 12-inch rough-in.

### What does 12-inch rough in size mean for toilets

If you’re planning on installing a new toilet, it’s important to know the rough-in dimensions. This is the space between the wall behind the toilet and the center of the waste pipe. Standard rough-in dimensions are 12 inches, but in some cases it can be anywhere from 10 to 14 inches. Keep this in mind when choosing a toilet so that you can be sure it will fit in your space.

When you are shopping for a new toilet, make sure to measure the rough-in size. This is the distance between the wall behind the toilet and the center of the drainpipe or the bolts that hold the toilet to the floor. It’s best to perform this measurement before you remove the old toilet. That way, you can be sure that the new toilet will fit in the space.

## How far from wall should toilet rough in Be?

The clearance from the center of the toilet to any adjacent fixture or sidewall is 15 inches. That’s the minimum (you can have more). So looking at the toilet, make sure there are at least 15 inches of clearance from the center of the toilet to any adjacent fixture (or wall).

Most codes require at least 15 inches (measured from the center of the toilet) from any side wall or obstruction and not closer than 30 inches center to center to any other sanitary fixture (The NKBA actually recommends 32 inches). There should be at least 24 inches of clear space in front of a toilet or bidet.

## Does rough-in have to be exact?

If you’re planning on getting a new toilet,you’ll need to measure the rough-in distance first. This is the distance from the wall behind the toilet to the center of the flange – the drainage pipe that’s connected to the sewer line. Getting an accurate measurement is crucial, since you don’t want to end up with a toilet that doesn’t fit.

To measure the rough-in distance, simply use a tape measure. Place the end of the tape measure at the center of the flange, and extend it out until it reaches the back wall. Make a note of the measurement, and then you’ll be ready to start shopping for your new toilet.

Elongated bowls are often considered more ‘hygienic’ due to the larger surface area of the bowl. This makes it easier for men and children to use with less mess, and is also a requirement for ADA use. The longer/wider bowl is generally easier to use for those with mobility issues.

### What is the rough-in for an elongated toilet

If you are planning on installing an elongated toilet, make sure to measure your rough-in first. Most elongated toilets are built to fit a 10” rough-in, but some are built to fit a 14” rough-in. Either way, you will need to know your rough-in measurement before you can purchase the correct toilet.

The flush valve drain opening is the best reference for determining what size flapper your toilet uses. If the drain opening is two inches, then you will need a two inch flapper. If the drain opening is three inches, then you need a three inch flapper.

## How do I know if my toilet is 2 or 3 inches?

When you are looking at the flush valve drain opening at the bottom of your tank, you can use the size of the opening to determine what size flapper you need. If the opening is about the size of a baseball or orange, you need a 2″ flapper. If the opening is about the size of a softball or grapefruit, you need a 3″ flapper.

The toilet and bidets must have a minimum space of 70cm in width and 120cm in length in order to be used effectively. If they are next to a wall, the minimum free space should be 20cm, and if there is an element on their side, they should not be placed less than 15cm away for greater usability. This will ensure that everyone is able to use these facilities effectively and maintain good hygiene.

### How do you determine toilet rough in

The rough-in measurement of a toilet is the distance between the wall behind the toilet and the center of the waste pipe. To measure the rough-in for your toilet, measure from the wall behind the toilet to the middle of the bolt caps (the caps holding your toilet to the floor).

If you need to move your toilet more than a couple of inches, you’ll need to demo the concrete to access and relocate water and waste lines. Then you’ll need to rebuild the concrete foundation and replace the sub-flooring, flooring, and fixtures.

## How do you know if your toilet is tight enough?

As a rule of thumb, try to tighten the toilet bowl bolts a turn or two at a time until you feel resistance. Then, try to wiggle the toilet bowl slightly. If there is no significant movement, you are probably tight enough. This tightening operation is a “feel” thing you get from experience, so be conservative and use your best judgement.

If you’re not sure what size rough-in you have, it’s important to measure before you purchase a new toilet. A new toilet won’t fit properly if the rough-in size is different from what you have.

The rough-in size for a toilet is 12 inches.

There is no definitive answer when it comes to toilet rough-in size. The best thing to do is to consult with a professional before making any decisions.
