Last Updated on May 19, 2022 by toilethaven
What is The Best 14-Inch Rough-In Toilet?
A toilet Rough-in is the distance between the finished wall behind the toilet and the center of the toilet drain. The standard rough-in of a toilet is 12 inches but you will still find 10 and 14-inch rough-in toilets especially in old houses.
While measuring the rough-in of a toilet, you should take care to make sure that you indeed measure from the finished wall and not the baseboard.
To measure the rough-in of an already installed, take the measurement from the wall to one of the toilet bolts. The bolts are normally at the center of the drain.
Finding a good 14-inch rough-in toilet is not as easy as it is to get a 12-inch rough-in toilet. There are not very many of them and that’s why I have written this post. To make sure that I have linked you to the best 14-inch rough-in toilet in the market.
Apart from just the rough-in, I will give you all the other toilet dimensions and features to make sure that you end up with the best one you can get. And now let’s look at them.

1. Kohler K-3949-0 Highline
Kohler K-3949-0 Highline is a single flush two-piece elongated comfort height toilet. It is available in white, almond, black and biscuit, although it is a little difficult to find it in the other colors other than white.
The Kohler Highline uses Kohler’s Class Five flushing technology which is meant for bulk flushing. The Class Five flushing technology involves the use of a canister flush valve instead of the ordinary flapper flush valve.
Unlike the flapper which is hinged to the flush valve on one side, the canister lifts off completely during flushing allowing water to flow into the bowl via a 360 degrees angle.
This ensures that the water flows from the tank to the bowl faster, creating more force and as result produce a powerful flush. In addition to that, the canister flush valve is designed in such a way that the water entry is larger than the exit.
That helps the water to build more pressure in the narrow exit further aiding the flushing efficiency using only 1.28 gallons per flush
The Highline’s bowl rim is at a height of 16.5 inches from the floor making it a comfort height toilet. It is therefore easier for the seniors, tall and people with limited mobility to sit and stand from the toilet. The elongated bowl further enhances your comfort while using this toilet.
Installation of this and other Kohler toilets is really easy using their DryLock system. In this system, the tank bolts come preinstalled underneath the tank. The tank has no bolt holes reducing the chances of it leaking. All you have to do is mount the tank on the bowl and tighten the bolts.
You will however be disappointed because this toilet is sold without a seat, wax ring, mounting bolts and bolt caps. You will therefore need to buy these things separately.
The Kohler K-3949-0 Highline dimensions are 31.625 inches in depth, 18.25 inches in width and 30.75 inches in height. You will receive a 1-year limited warranty after the purchase.
2. American Standard 215FC104.020 Cadet PRO
The American Standard 215FC104.020 Cadet PRO is a single flush two-piece elongated comfort height toilet. It is available in white, linen and bone.
The 14-inch rough-in Cadet PRO uses American Standard’s Cadet flushing system which incorporates the use of a 3-inch wide flush valve and an extra-large trapway.
That way, water is dumped in the toilet bowl faster and forcefully resulting in a power flush compared to a 2-inch flush valve toilet. Its consumption is only 1.28 gallons per flush meaning it is WaterSense certified.
The bowl rim height is at a comfort height of 16.5 inches. When you add the extra inch from the toilet seat you should be sitting at a height of 17.5 inches. Coupled with an also comfortable elongated bowl, this toilet is a really good one.
Its surface is coated with the American standard patented EverClean additive which inhibits the growth of mold, mildew and odor-causing bacteria. It therefore makes it super easy to clean the toilet and keep it that way for longer.
American Standard is not different from the others as you will also be required to buy a toilet seat and other accessories separately. They will however give you color-matched toilet bolt caps.
The American Standard 215FC104.020 Cadet PRO dimensions are 30.125 inches depth, 17.325 inches width and 30.325 inches height. It comes with a 5-year warranty.
3. Kohler 528484 K-3947-0 Wellworth
The Kohler 528484 K-3947-0 Wellworth is a single flush two-piece round-front standard height toilet. It is available in white, black, almond and biscuit.
Just like the Kohler Highline 14-inch rough-in, this toilet also uses the Class Five flushing technology meaning its flushing power is great. With a consumption of only 1.28 gallons per flush, this toilet is WaterSense certified and can therefore be sold anywhere in the United States.
Although comfort height toilets are the go-to toilets these days, standard height toilets still have their “fans” and Kohler 528484 K-3947-0 Wellworth is one such toilet. Its bowl rim is at a height of 14.5 inches from the floor. Standard height toilets are a great choice for people who are not very tall and also children.
This toilet has a round-front bowl. Although elongated toilets are known to be comfortable, round-front bowls are a great choice if you have a small bathroom and you want to save every possible inch of space.
Kohler Wellworth 14-inch also uses the DryLock tank installation system. This system uses 3 bolts which makes the tank really sturdy and prevent leaks between the tank and the bowl.
It also does not come with a seat, wax ring, mounting bolts and bolt caps. Buying this items separately will of course slightly increase the total price of the toilet.
The Kohler 528484 K-3947-0 Wellworth dimensions are 29.625 inches in depth, 18.25 inches in width and 28.75 inches in height. It has a 1-year limited warranty.
How to Buy the Best 14-Inch Rough-In Toilet
So what factors should you consider while buying a 14-inch rough-in toilet? Although your choice is only limited to 3 (if you follow our guide) there is still some things you should consider before making the ultimate purchase. A toilet is a long term investment and you should therefore take your time before settling on a certain product.
1. Standard Height vs Comfort Height Toilet
A standard height toilet has a toilet bowl rim height of about 15 inches while a comfort height toilet has a bowl rim height of about 17 inches. Comfort height toilets are also called right height, chair height, universal height or ADA-compliant toilets.
Comfort height 14-inch rough-in toilets are a great choice for the seniors, tall, physically impaired or just about anyone who would have a problem sitting and standing from a standard height toilet. Standard height toilets on the other hand are more suitable for not too tall people and children.

2. Round vs Elongated Toilets
Round-front toilets have a circular bowl while elongated toilets have an oval-shaped bowl. A round-front bowl is 16.5 inches long while an elongated bowl is 18.5 inches long on average.
The main advantage of installing a round toilet is that it takes less space in the bathroom compared to an elongated toilet. Elongated toilets on the other hand provide you with a bigger surface to sit on which is streamlined in accordance to your body hence are more comfortable.

3. The Brand
The brand actually matters big time. If a brand has a history of making great products then you tend to trust it more. The opposite is also true.
In this post we have only focused on Kohler and American Standard which are both well-known brands in the United States and among the top 3 toilet manufacturers. Both have different patented flushing styles which have been proven to work time and time again.
Yes. Color! It is not always that toilets have to be white. In fact in the 50s and 60s when bathrooms were a bit more colorful than they are today, toilets were sold in different bright colors and they also had colored toilet paper to match.
These days people have toned down although the colors are slightly coming back but not the bright blues and pinks. Black toilets are for instance really cool to have. If you would like a different color other than white don’t be afraid to get one. Personally I like bone from American Standard and black from Kohler.
5. Water Consumption
All the toilets we have reviewed here are all low-flow toilets with a consumption of 1.28 gallons per flush. It therefore means they are very water-efficient and as a result WaterSense labeled and can be sold all over the USA without restrictions.
Despite their low consumption, they flush amazingly well due to the engineering enhancements that have been done on their flush valves.
If you are replacing an old 3.5 gallons per flush 14-inch rough-in toilet with any of this toilets, your water bills will come down and you will enjoy a strong flushing toilet.
How Do You Measure a Toilet Rough-In?
The method of measuring a toilet’s rough-in differs depending on which type of toilet you are measuring. Standard, rear-discharge, and corner toilets have different methods of rough-in measurement.
To measure the rough-in of a standard toilet, take a measuring tape and measure the distance from your toilet’s rear finished wall to the center of the toilet drain. With an installed toilet you take the center of the drain where the toilet bolts are.
A ½ inch error is allowed. If you therefore get a measurement of 13.5 or 14.5 inches you should automatically convert it to 14 inches.
1. Can you replace a 14 inch rough in toilet with a 12 inch rough in toilet?
Yes you can. But before you celebrate I will also go ahead and inform you that a 2-inch gap will be left between the tank and the wall. If you are a perfectionist you won’t like that. The only solution in that case will be to replace a 14-inch rough-in toilet with another 14-inch rough-in toilet.
2. Does Toto have 14-inch rough-in toilets?
No. Toto uses a unifit adapter to convert a 12-inch rough-in toilet into a 14-inch rough-in toilet. The adapter however does not work with all toilet models. It can only be used with skirted Toto toilet models.
If you would be interested in a really good 14-inch rough-in Toto toilet, get the Toto Vespin II. It is the skirted version of Toto Drake II and comes with the unifit adapter.
