A rough-in is the distance between the floor drain and the wall. The clearance is the amount of space needed to use it properly. For most toilet installations, the rough-in is 12 inches. Sometimes in small baths or older homes it can be 10 to 14 inches.
While a 10-inch rough-in toilet can plausibly fit into a 12-inch rough-in (though a longer connector may be needed), the same cannot be said for using a 12-inch rough-in toilet in a 10-inch rough-in. A 12” rough-in toilet will not fit in a bathroom with a 10” rough-in size.
The standard rough-in is 12 inches, though you may encounter 10-inch and 14-inch rough-ins in older homes.

What toilet height is best for seniors? Seniors and disabled users will have an easier time sitting and standing up from a comfort height toilet, which measures 17 to 19 inches from the ground to the seat.
Medicare won't cover raised toilet seats. These toilet seat risers are considered convenience items. Fortunately, these items are easy to find and inexpensive. These seats assist with using and getting up from the toilet more easily.
Elongated bowls are also considered more 'hygienic' in that the larger surface area of the bowl makes is easier for men and children to use with less mess. The longer bowl size is also a requirement for ADA use, and the longer/wider bowl is generally easier to use for those with mobility issues.
The standard rough-in dimensions for toilets is 12 inches. In older homes or small bathrooms, you'll sometimes see rough-in dimensions of 10 inches or 14 inches. Determine your bathroom's rough-in by measuring from the wall behind the toilet to the middle of the bolts on the base of the toilet.
The standard (or at least most common) toilet rough-in distance today is 12 inches. However, older homes, and even modern homes, may come with 10” or 14” rough-in distances depending on the size and shape of the bathroom. For example, a 10” rough-in is more common for smaller apartment bathrooms or powder rooms.
2-Allowing for the Appropriate Space from Left-to-Right:
Any sidewall or nearby fixture must be at least 15" away from the toilet's flange. However, 15" is the absolute minimum. A 15-inch distance from the vanity, shower, tub and back and side walls are required to accommodate the toilet flange.
For most toilet installations, the rough-in is 12 inches. Sometimes in small baths or older homes it can be 10 to 14 inches.
Plumbers can install toilets so the tank is snug against a wall, but this requires quite a bit of planning. What's more, if the tank is tight against the wall, the tank lid might not fit well because the lids are larger than the tank and often have an overhanging rear lip. It's easy to keep peace in these situations.
The optimal height of a sink drain is between 16 and 20 inches from the floor, with 18 inches being the most common height. Bathroom drain height ranges from 16 to 24 inches, and kitchen sink drain height falls between 16 and 20 inches depending on the sink and cabinet height.
Where existing plumbing is concerned, an elongated toilet will fit in the same location as the original in most situations. Plumbing codes usually require that the drain pipe the toilet sits over be a standard offset from the wall behind it.
Overall, selecting a 10-inch rough-in toilet offers a combination of space-saving benefits, versatility, and efficient performance, making it a smart choice for many bathroom projects.
To move the toilet more than just a couple of inches, you will have to demolish the concrete to access and relocate water and waste lines. Then you will have to rebuild the concrete foundation and replace the sub-flooring, flooring, and fixtures.
The standard rough-in size for a toilet is 12 inches in contemporary houses and 10 inches in older homes. These are the toilet rough-in dimensions: Supply line (vertical): 8 1/4 inches of height to accommodate most base moldings.
The larger the toilet outlet, the better the overall toilet performance will be. American Standard Toilets are designed with outlets ranging from 1 3/4” all the way up to an industry leading 2 3/8” outlet.
If the rough-in size doesn't match the dimensions of the toilet, it won't fit properly. Typically, the standard rough-in size is 12 inches, though older homes may have 10-inch or 14-inch rough-ins. Smaller bathrooms often feature 10-inch rough-ins, while larger ones may have 14-inch rough-ins.
Get a tank that matches the size of your toilet bowl's gasket. The toilet gasket is the main hole where water travels from the tank into the bowl. Measure the size of the gasket on your toilet bowl with a tape measure so you can buy a tank that has the same size hole.
The standard toilet size has a depth of 28-30 inches, with a width of 20 inches and a tank height of 27-32 inches.
Elongated toilets can have a more powerful flush system, which may avoid having to “double flush.” Elongated toilets require more room than a round toilet, so take this into consideration if space is an issue. Round toilets can be installed for potty training, then replaced with an elongated one as your child goes up.
Toilet height is measured from the floor to the top of the seat. Most often, toilets fall somewhere between 15" and 19", with standard toilets coming in under 17". Chair-height toilets measure 17" or more.
An elongated bidet seat will still mount on a round toilet, as well as function just fine, but the aesthetics and comfort of the seat will be greatly diminished.
