What is a Rough-in Measurement
If you are buying a new toilet, it’s essential to know what a rough-in is and how to properly measure it. The rough-in is a distance between the wall and the mounting holes on the flange. Toilets usually have 10”, 12”, or 14” rough-in, with 12 inches being the most popular in the US.
You can even replace a 14-inch rough-in with a 12-inch version, but you will end up with a 2-inch gap. However, you can solve the problem by installing an offset toilet flange. Also, you might need a new wax ring and mounting bolts when replacing your old commode with an updated model.
The Difference Between Rough-ins
While most toilets have a rough-in of 10 or 12 inches, a 14-inch rough-in is a bit rare. A 10-inch version is much slimmer since it has to allow for decreased distance. On the other hand, 14-inch rough-in tends to be much bigger and longer, which can impact the overall cost of your new toilet.
In most cases, if you have a compact bathroom, or if your house is older, you will find a 10-inch rough-in on your toilet. Also, there is a good chance that the bowl you choose will be round.
A 12-inch rough-in is the most common because it can fit toilets of almost any type and style. However, even though it’s the standard size, be sure to do proper measurements before buying a new commode.
Before choosing a 14-inch rough-in, remember these are usually meant for smaller bathrooms and older homes. When buying a new toilet, your options will be a bit limited, but there are still some great models out there, including the models mentioned in this list.

4. Sterling 402079-96 Windham
Among all Sterling toilets, this model is one of our top choices. Not only because it’s a 14-inch rough-in unit, but because of its great features. Right off the bat, we noticed this unit has a siphonic flush, which perfectly cleans any waste in a single go. The water surface is large, which keeps the bowl cleaner and reduces smell.
Since the toilet has an elongated bowl, it’s not an ideal choice for smaller bathrooms. Despite this, the extended rim length makes it very comfortable for adults. This model also has a beautiful glossy finish, making it an attractive addition to any modern bathroom.
5. ProFlo PF140TBS

What we adore about this model is its bowl-only configuration so that you can choose a tank style that suits your preference.
Compared to round-bowl toilets, this unit is 1.5-inch longer and provides more comfort. Although it’s not the best choice for young children, it will perfectly suit adults of any age. The toilet is made of strong and sturdy vitreous china and has a non-porous coating on its surface. We also couldn’t help but notice that this model has no certifications or an EverClean treated exterior. Even without this last feature, it’s more than decent considering the price.
Buying Guide: What to Look for When Buying a 14-inch Unit
Water Consumption
There are two disadvantages of a toilet that consumes too much water. At first, it will directly increase your monthly bills, which can lead to a significant sum at the end of the year. Also, it is not eco-friendly, and specific models are even banned in certain states. On the other hand, you need to be sure that the model you choose can perform well with a low amount of water per flush.
Bowl Shape
Toilet bowl shapes can be either round or elongated, and both of these have their advantages. Elongated bowls are more comfortable, but they take more space. In some situations, even a few inches can be too much. That’s why round bowls are excellent for smaller bathrooms but are also less comfortable.
Toilet Price
No matter what you intend to buy, price is always the first factor to consider. Buying a new toilet is a long-term investment and investing slightly more money than you planned can be useful. Also, you need to clarify which features do you need, since it will directly affect the price. If you want a toilet with LED nightlights, remote controller, seat heat adjustment, and similar, don’t be surprised by the price of a couple of thousands of dollars.
One-Piece vs. Two-Piece 14-inch Rough-In Toilet
Both of these two styles have their pros and cons. One-piece units usually look stylish and luxurious, making them ideal for modern bathrooms. They are also easy to maintain since there is no place susceptible to dirt. Since they come as a single piece, they almost never cause leaking. On the other hand, if a one-piece toilet breaks, you will have to replace the whole unit. They are also much heavier and more difficult to carry to the installation location.
Two-piece units are usually cheaper, but connecting the tank and the bowl directly increases installation time. They are also larger, more susceptible to dirt, and not ideal for smaller bathrooms. So, if you are looking for a cheaper solution, a two-piece unit is a way to go.
Glazing
Since we use toilets every day, glazing is a very important thing to consider. If the unit has a smooth surface, the waste will much easier go down and won’t stick. It means that you will have to do less maintenance, but also, the toilet will be more hygienic without all the possible bacteria and mold. If you are looking for a unit with a high-quality glaze, search for labels such as EverClean, Cefiontect, and Sanagloss. These have been tested many times over the years.
Accessibility
Accessibility is another essential thing to consider, especially if you live in a family with young children, elderly, or disabled people. If you want to be sure that your toilet doesn’t lack accessibility, look for an ADA-compliant unit. These usually have a bit higher bowls, which release the tension on joints and muscles while you are sitting.
Trapway
Not all units have the same trapways, but what is the difference? With a large trapway, the toilet can push more waste, but that’s not always necessary. Units with larger trapways can be more expensive, but a standard trapway is good enough for most people.
Things to Know Before Roughing-in a Toilet
As you can see, the toilet rough-in is an important measurement to have before buying, but there are four more things that you have to measure accurately. If you don’t do this correctly, the final results will be pretty frustrating to correct later.
The Distance Between the Toilet Flange and the Back Wall
While taking measurements from behind the wall, be sure to center the toilet flange at a distance of 12 inches from the wall. This usually applies to most toilets with this size of a rough-in, but if your model is different, pay attention to the difference.
The Distance Between the Center of the Unit and the Sidewall
This measurement shouldn’t be less than 15 inches because it’s the distance between your new toilet and the sidewall, or any other fixture, on both sides. For example, if the tub is next to your commode, it should be at least 15 inches away or more.
The Distance Between the Front of the Toilet and any Fixture
This measurement might vary between countries since it mainly relies on local plumbing codes for standard distance. If plumbing requirements in your area are under IPC, you will need, at a minimum, 21 inches of clearance. However, if you live in a city that is under UPC, you will need at least 24 inches instead. Remember, this is the amount of space between the front-most side of your toilet and any wall, door, or other similar obstruction.
Where to Put the Water Supply Line
Find the center of the closet flange and measure six inches to the left. Then, go seven inches up above the floor, and that is your ideal position for the water supply line. If the water line comes too high or too low, you might need to do additional fixing, which might turn out very ugly. You can even go six inches above the floor, but not lower than that.
Frequently Asked Questions
Should a Toilet Tank Collide With the Wall?
It depends on the rough-in of the unit. If it’s smaller, you will have some space – if it’s not, that it may touch the wall.
Can I Change the Rough-in Measurement of My Unit?
Usually, when you replace a toilet, it should have the same rough-in measurement as the previous unit. However, if the rough-in is larger, you will need to modify the plumbing configuration. The only other option would be to move the wall.
What Is the Minimum Clearance in Front of the Toilet?
As a rule of thumb, it should be at least 21 inches. There shouldn’t be any wall or fixture in that distance. Also, the distance shouldn’t be less than 24 inches when it comes to the Uniform Plumbing Code. These are, however, the minimal measurements; the distance can be much greater than that, as long as it’s comfortable to use the toilet.
Verdict
Although 14-inch rough-in toilets are a bit rare, you will be satisfied with any unit from the list. These are all manufactured by popular companies and made from top-quality materials. However, if you still want to shop on your own, be sure to check our buying guide for some useful tips.
