14-inch Rough-In Toilets with Longer 4Fit – Best 6 Reviewed in 2024
You might think that buying a replacement toilet is pretty simple – just find a toilet with the features you like and press the ‘buy’ button. However, there are a few important considerations that will help you make a successful decision. One of the main ones you should pay attention to is the rough-in
A toilet rough-in is the distance from the finished wall to the center of the toilet’s floor drain or waste outlet. The measurement is best made before the old toilet is removed. The most common measurement for a toilet rough-in is 12 inches, but if you have a 14-inch model to replace, there are still high-quality options to choose from.
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.
Top 14-inch Picks
Rough-in Measurements Explained
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 inches, 12 inch, or 14 inch rough-in, with 12 inch 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. You might need a new wax ring and mounting bolts when replacing your old commode with an updated model.
Difference Between Rough-ins
While most toilets have a rough-in of 10 or 12 inch, a 14 inch rough-in is less common. A 10 inch version is much slimmer since it has to allow for a shorter distance. On the other hand, 14 inch rough-in tends to be much bigger and longer, which can impact the overall style 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-is are 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.

This toilet is great for shorter individuals and those with children due to its height and structure.
Flushing Power
Similar to the Kohler Highline K-3949-0, the K-3947-0 also offers outstanding performance at high efficiency. Kohler K-3947-0 comes with a single-flush option, but it uses only 1.28 gallons per flush, saving you over 16,000 gallons of water each year.
The precision-engineered tank, bowl, and trapway create a strong suction strength that gets rid of any waste load in a few seconds without any leftover streaks. The toilet has the same Class Five Flushing Technology as its other Kohler counterparts.
Design
This two-piece toilet has a round bowl style that is excellent for smaller bathroom layouts. There is also a trip lever on the left that is beautifully coated and polished in chrome, although we believe it is mountable on either side.
No professional help is needed for the installation process. With Wellworth’s three-bolt quick-connect installation, your new toilet will be working smoothly in no time.
Something to keep in mind is that the toilet’s seat height is on the shorter side, standing at 14.5”, and comes with a round bowl. We do not recommend this toilet for taller individuals and those with mobility issues.
The toilet is available in white, biscuit, or black. A seat and supply line is not included but a bolt cap accessory pack, tank accessory pack, tank cover, and trip lever are included.
The Wellworth is compatible with the Purefresh Quiet-Close Round Front Toilet Seat and Purefresh Round-Front Toilet Seat as well as the Puretide Quiet-Close Round-Front manual bidet seat.

Our Take on Reviews
Buyers were delighted about the quality of this unit. They like the power behind this compact option, with one review stating: “It’s more specific to our needs in a small bathroom closet with the lower profile and a 14” rough-in setback.” The height isn’t for everyone, as taller individuals and those with mobility issues are unable to comfortably use the toilet.

Buyers Guide for 14-Inch Rough-In Toilets
Here are seven factors to consider when buying a new 14-inch rough-in toilet.
✓ Water Consumption
High-efficiency toilets are more eco-friendly and save you money on your water bills by reducing water consumption. Considering the fact that toilet use is responsible for 30% of residential water usage, you can see where this is important to your monthly budget. Many states also require the installation of high-efficiency toilets, because with widespread use they reduce the need for water restrictions during drought conditions.
Take a look at the difference between 1.28 vs. 1.6 GPF toilets.
✓ 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.
✓ Toilet Price
Buying a new toilet is a long-term investment, and price is always a primary factor to consider. It would be helpful to prioritize the features that are important to you, and then you can make a smart decision. If you want a toilet with LED nightlights, remote controller, seat height adjustment – go for it! It will obviously cost more, but will be worth the extra money.
✓ One-Piece vs. Two-Piece
One-piece units look stylish and luxurious, making them ideal for modern bathrooms. They are also easy to maintain since there are fewer nooks and crannies 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 need to replace the whole unit. They are also heavier and more difficult to carry to the installation location.
Two-piece units are usually cheaper, but connecting the tank and the bowl increases installation time. They are also larger, more susceptible to dirt, and not ideal for smaller bathrooms.
You may be interested in our reviews of one-piece toilets.
✓ Glazing Finish
Since we use toilets every day, glazing is important 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 (American Standard), Cefiontect (TOTO), and Sanagloss (TOTO). 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 physically challenged people. ADA-compliant toilets have slightly taller bowls, which release tension on joints and muscles while you are sitting. They also have elongated bowls, for superior comfort.
✓ 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 normally more than sufficient for a residential toilet.
Measuring Tips
There are four accurate measurements before you can install your 14-inch rough-in toilet.
1. Toilet Flange and Back Wall Distance
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 check the specifications and measure accordingly.
2. Center of Unit and Sidewall Distance
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.
3. Front of the Toilet and Other Fixtures Distance
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.
4. Water Supply Line Placement
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 repairs, 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 Directly Touch the Wall?
It depends on the rough-in of the unit. If it’s smaller, you will have some space – if it’s not, then 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 within 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.
Final Thoughts
Although 14-inch rough-in toilets are less common, you will be satisfied with any unit from the list. These are all manufactured by popular companies and made from top-quality materials, so decide what features are important to you and get started with the installation!
