How To Find 10 Inch Rough In Toilet – The Buying Guide

Finding a suitable 10 inch rough in toilet for your bathroom may be confusing due to the countless options available on the market. Here are essential factors that can help to make the right decision.

Pros And Cons Of 10 Inch Rough In Toilets

The first thing is to look at the benefits and drawbacks of 10 inch rough in toilets.

10 Inch Vs. 12 Inch Rough In Toilet

Most people don’t know the differences between 10 inch and 12 inch rough in toilets. Here is a detailed comparison between 10 inch and 12 inch rough in toilets.

• Measurement

A 10 inch rough in toilet is commonly found in old homes, whereas 12 inches rough in toilet is used in modern homes. There are few options available in 10 inch rough in toilets, whereas you can find a variety of options in 12 inch rough in toilets. You can easily find standard or chair height, elongated or round, and one piece or two piece toilets on the market.

• Clogging problems

Neither size clogs by design — clogging depends on the trapway size and flush performance, not on the rough in, which is only the distance from the wall to the drain.

• Water consumption

A decade ago, people expected 1.6 gpf from a 10 inch rough in toilet. However, nowadays, the water consumption of these toilets is lowered to 1.28 gpf, which is commonly found with 12 inch rough in toilets. You can easily save money on water bills if your toilet is compatible with 1.28 gpf. However, it is essential to consider that there must be a good flushing performance to remove waste from the bowl without the requirement to make another flush.

Essential Factors to Consider

• Learn about innovations

There is a consistent stream of modern innovations that make toilets work harder, stay cleaner, and last longer than ever before. For instance, self cleaning toilets help save time and reduce efforts to perform one of the undesired chores in your home. These toilets are an ideal solution to add a sparkling clean touch to your bathroom without wasting extra effort.

There is a wide range of toilets available with innovative technologies. The ultra smooth glaze, along with antimicrobial properties, makes them appealing. It gives your toilet a super smooth, new finish which stays cleaner as the soil has a tough time clinging to it. Also, it helps to inhibit the stain and odor-causing bacteria growth on the surface.

• Water saving ability

Water conservation is essential to the environment, and it can also help you save money on water bills. Standard toilets flush at a rate of 1.6 gpf, which is less than 50% of the water utilized by older 3.5 gpf toilets. Thanks to advanced hydraulic designs, these 1.6 gpf toilets perform better than older toilets and also remove waste effectively while preventing clogging issues.

HETs (High efficiency toilets) flush at the rate of 1.28 gpf and save 20% more water compared to 1.6 gpf toilets. Flushing performance isn’t affected by less water consumption. There are ultra-high efficiency toilets available that use only 1.0 gpf without affecting the flushing performance. However, most people prefer dual flushing as they offer both partial and full flush options.

• The right configuration for the bathroom

There are different configurations available to suit the different needs of your bathroom. Choosing the right configuration ensures that the toilet has a decent look and design for the bathroom.

One piece toilets are available with six to ten individual pieces that are installed in a single seamless unit with both bowl and tank already attached. The result is an elegant, sleek, and hand crafted toilet with no crevices between the bowl and the tank to catch dirt and odors.

When it comes to two piece toilets, they feature a separate bowl and rank, which are bolted together during installation. There are raised area that allows for cleaning of the offending material and prevents odors causes accumulation between the tank and bowl.

Round front toilets have a bowl with a compact design which makes them an ideal choice for small bathrooms and powder rooms. If you want extra comfort, elongated bowl shapes are available in 10 inch rough-in too — the Swiss Madison SM-1T127 pick above is one example.

On the other hand, elongated bowls extend out further with additional room in the front for extra comfort. There are compact elongated toilets available featuring an elongated shape that fits into the small space, like the round front toilet.

• Determining Rough in and Size Requirements

Toilets are available in different sizes, so ensure to consider the depth, width, and height of the available space before making a decision.

Most toilets bolt to the bathroom 12 inches from the wall. This is called a rough in dimension.

10 inch rough in toilet and 14 inch rough in toilet are available for the bathroom with less or additional space compared to the standard 12 inch rough in.

• Toilet Comfort

A standard toilet bowl rim comes with 15 inches of height from the floor. The toilet seat ring adds an extra ½ to 1 inch of height. Most people find a tall toilet bowl more comfortable than a traditional one. It is recommended to choose a toilet with a rim height of 16-1/2 inches from the bathroom floor.

• Right Flushing system

There are various flushing systems available for different needs. Single flushing system uses 1.28 gpf and 1.6 gpf to remove toilet waste. On the other hand, a dual flushing system offers two options to choose from.

The partial flush uses 0.8 gpf, which is good enough to remove liquid and small waste. The full flush with 1.6 gpf is ideal for large and solid waste removal. Nowadays, most people prefer dual flush as it helps to save water and reduce water bills significantly.

• Bathroom design is important

Before you make a decision, it is essential to consider the design style of a bathroom. You can easily find a toilet that goes with every look if you have a more transitional, traditional, or modern flair. A conventional bathroom features two piece toilets with a classic appearance for a timeless look. On the other hand, a transitional and contemporary bathroom has a more updated design. You may need sleek one piece or two piece toilets for a modern bathroom with clean lines and geometric flair.

• Toilet performance

The bathroom is one of the most used rooms in every home. That’s why when choosing a new toilet, it is recommended to ensure it performs to the highest standards. Selecting a toilet with powerful flushing performance helps to eliminate clogs and dirt in the toilet bowl.

A MaP score is used to determine the Toilet performance grade, which represents the number of grams of waste eliminated from the bowl in one flush. Toilets with a MaP score of 1000g to 600g is considered to have excellent flushing performance. These toilets can remove up to 35 oz. of waste in one flush.

Final Words

If you have a small bathroom or have limited space in the bathroom, it is recommended to choose 10 inches rough in toilet. Not only do these toilets help to save space, but they also offer great flushing performance with comfortable use. Depending on your bathroom size, you can easily find the best toilets with 10 inches rough in. However, it is essential to measure the size of your bathroom before making a decision. Sometimes, an inch is enough to ruin your hours of effort while replacing the toilet.

Plumber’s field tip: measure the rough in from the finished wall to the center of the closet bolts — not from the baseboard, which can steal half an inch and leave the tank tight against the wall. On a true 10 inch rough in, dry-fit the bowl before you drop the wax ring; if the tank lid touches the wall, you still have time to reach for an offset flange instead of forcing the bowl forward.

Frequently Asked Questions

Can a 10 inch rough in toilet clog more easily than a 12 inch one?

No. Rough in is only the distance from the finished wall to the center of the drain — it has nothing to do with clogging. Clog resistance comes from the trapway size and design and from flush performance, which is why a well-designed 10 inch model with a fully glazed trapway and a strong MaP score clears waste as reliably as any 12 inch toilet.

Can I install a 12 inch rough in toilet on a 10 inch rough in?

Not properly. The bowl would sit two inches too far forward for the flange bolts, and the tank would end up hard against — or into — the wall. An offset flange can shift a drain roughly an inch to an inch and a half, which sometimes rescues a borderline measurement, but the reliable fix is a toilet built for a 10 inch rough in.

Which is the best 10 inch rough in toilet in this list?

For most bathrooms, the Kohler Highline K-3889 — it is Comfort Height, flushes at 1.28 GPF with a Class Five canister, and Kohler publishes a true 10 inch rough in version. If you want TOTO, choose the Drake II in its .10 configuration (MS776124CEFG.10#01); the standard Drake CST776CSFG is a 12 inch rough in model.

Do 10 inch rough in toilets come in comfort height?

Yes. The Kohler Highline K-3889 in this list is a Comfort Height model with a chair-height bowl, and the American Standard Cadet PRO 215AB004 is a Right Height model with a 16-1/2 inch rim. Compact one-piece models tend to sit lower, so check the rim height before ordering if standing up is a concern.

Does a 10 inch rough in toilet use more water?

No. Flush volume is set by the toilet’s design, not its rough in. Models in this list range from 1.28 GPF (the Kohler Highline and the Drake II) to 1.6 GPF (the original Drake and the Cadet PRO). A 1.28 GPF model meets the EPA WaterSense limit and can cut toilet water use by 20 percent compared with a 1.6 GPF toilet.

Are there 10 inch rough-in toilets in elongated bowl shape?

Yes. The Swiss Madison SM-1T127 on this list is a 10 inch rough-in toilet with an elongated bowl, and several TOTO Drake 10-inch models come with elongated bowls too. The buying guide notes that compact elongated toilets are available for small bathrooms — you get the extra front-room comfort of an elongated bowl without needing a 12-inch rough-in.
