What’s a toilet rough-in and why does it matter? The experts at Toiletable are here to answer any and all of your toilet-related questions. Technical terms are can be a real doozy. We’re here to make it simple.
A toilet rough-in is the distance between the wall behind the toilet and the center of the drainpipe. While a standard rough-in is 12 inches, smaller bathrooms are often set up with a 10-inch rough-in to maximize space. A smaller rough-in positions your toilet closer to the wall, allowing extra legroom in the front.

The size of the rough-in for a toilet is quite important. Your plumber can only install toilets based on the existing rough-in for the main drain pipe. And, once your rough-in is set, it’s very really difficult to change. Therefore, plan accordingly when designing and new bathroom space to ensure you build everything as you’d like.
Toilets most frequently come with a 14”, 12”, or 10” rough-in. The rough-in must be measured properly and precisely! If it is not, you may lack free space to install the toilet correctly. Be sure to know your bathroom’s rough-in and pick a toilet that matches to avoid any installation issues.
Deciding if a 10-inch is Right For You
If you are thinking about whether you should get a 10-inch rough-in or not, there are a few details to consider:
To start, going with a 10-inch rough-in allows you to gain only a few inches of free space. If these extra few inches will increase the usability of your bathroom, like allowing you to open a cabinet or shower door fully, then the 10-inch rough-in can make a big difference. If the extra inches won’t significantly change how you use the bathroom however, it may not be worth the investment.
Another consideration is whether your bathroom already includes a 10-inch rough-in. Converting your existing rough-in to a 10-inch option is a complex process that can be very expensive. However, if your bathroom already has a 10-inch rough-in, you can make the most of it to maximize your bathroom space.
Toilet Models Available
Finally, is there a 10-inch rough-in toilet on the market that meets your needs? Compared to the more common 12-inch rough-in options, there are fewer buying choices for 10-inch rough-in toilets, so make sure you’ll be able to find a toilet that fits your needs if you’re going with a 10-inch rough-in
However, just because your bathroom space is limited, doesn’t mean you have to compromise on efficiency or looks. Our Top 7 10-Inch Rough-In Toilets is a compilation of our favorite models on the market right now.

“As always, we have to start out with our favorite. The TOTO Drake CST744SF is one of the best models on the market thanks to its affordable price, compact rough-in, and simple look.”
TOTO is widely known for its high-quality 10-inch rough-in toilets. This two-piece sleek option is various built-in features, along with a smooth look that helps streamline the cleaning process.
The TOTO Ultramax’s G-Max flushing system uses an extra-large siphon jet for maximum suction power and a wide 3” flush valve to pack a punch in every flush. The toilet’s fully glazed trapway also reduces the chance of clogging.
The CST744SF uses the industry standard. 1.6 gallons per flush and has the highest MaP score possible of 1,000 grams. The toilet comes with a chrome trip lever that is easy to use.
We love the look of the TOTO Drake because it’s undemanding and simple. Sometimes you want the rest of your bathroom aesthetic to do the talking for you. The CST744SF would fit in any bathroom theme while getting the job done.
The most comfortable aspect of the CST744SF is the toilet’s height. Standing at 17.25 inches, the toilet feels like a standard chair. Higher toilets are easier to sit down and stand up from. The elongated bowl further elevates the user experience by dispersing body weight.
The best part? The CST744SF is ADA-compliant when installed with the trip lever on the approach side.
The toilet comes with a bowl, tank, and cover. The tank and cover can either come with a standard left or right-hand trip lever or come as a bolt-down lid with a right-hand trip lever. A seat is not included. However, this TOTO model is compatible with most TOTO seats, such as the SoftClose model.
This Drake model only comes in cotton. If you are interested in more of the TOTO Drake models, check out our Drake Round Up here.

Buyers Guide for the Perfect 10-inch Rough-in Toilet
After you’ve decided whether a 10-inch rough-in toilet is right for you, there are other features to consider to select the specific best option:
Type of Toilet
There are two main types of toilets: one-piece and two-piece designs, which depend on whether the bowl and tank are fused together. Typically, one-piece toilets are smaller than their two-piece counterparts, and they’re generally easier to maintain as they don’t have hidden places between parts.
On the other hand, two-piece models come with the bowl separate from the tank. Their biggest advantage is that they are much cheaper than their counterparts, and can be easier to install. However, you may experience shipping problems with two-piece models.
Not a lot of people realize that their toilets can have a huge impact on their water bills every year. Now, different kinds of toilets offer different flushing capacities. According to the EPA, your toilet should not use more than 1.6 gallons of water per flush.
Most water-saving toilets stick to this standard. Still, certain more effective models have a rating of 1.28 gallons per flush, which can come with added benefits like EPA WaterSense certification.
Right Height Selection
Most manufacturers often use terms such as comfort height, right height, and universal height. These different options can sometimes be very confusing to some people. Basically, these different terms refer to how far the toilet is from the ground. For example, the standard height for most toilets is around 16 inches. It’s important to also note that adding a toilet seat can add additional inches to your toilet.
Exact Rough-in Measurements
As mentioned above, if your rough-in doesn’t match the rough-in in your bathroom, you’ll have major complications when installing a toilet. If you’re even one inch off between both, you may not be able to install the toilet at all. Be sure to select a toilet that matches your bathroom’s rough-in, whether that be a 10-inch rough-in or another size.
Type of Flushing System
Flush technology is another factor to consider when buying a toilet, as it determines the overall efficiency and flushing power. In general, more powerful systems will keep your bowl cleaner and are less likely to clog even with one flush. Looking for a more powerful flushing system will help you save water and better maintain a clean toilet bowl surface.
Water Restrictions Standards
Don’t forget to check for any water restriction standards in your state before purchasing a toilet as well. For example, some states such as Texas and California don’t allow toilets that use more than 1.28 gallons per flush. Most other states are fine with 1.6 gallons per flush, however, you should always confirm before making your final toilet choice.
Another essential detail to consider is the type of bowl – you’ll typically be able to select either a round or elongated bowl. Round-shaped bowls are better for those who want to save space. Elongated bowls, on the other hand, take up more space, but provide more room for your legs, making them more comfortable. Regardless of which option best fits your needs, you’ll also want to see if the toilet comes with an anti-microbial finish or other additional helpful features.
Warranty and Certifications
One last factor to keep in mind is the type of warranty. Warranty is the best way for a company to ensure the quality of their toilets. The standard warranty for many toilets is about 1 – 3 years. However, if you’re very worried about potential issues with the toilet, you can look for an extended warranty option, with warranties lasting up to 5 years or even longer.
Frequently Asked Questions
Is a 10-Inch Rough-in Toilet the Best Solution to Save Extra Space?
Long story short, while it can be an effective option, a 10-inch rough-in might not always be the best. Specifically, you should consider getting this kind of toilet only if saving a few inches will get you the space you need, particularly if your bathroom is already set up with a 10-inch rough-in. There are other options available as well that can save even more space, such as a corner or a wall-hung toilet.
What Are the Main Differences Between 10-Inch and 12-Inch Rough-ins?
There aren’t many significant differences between the 12-inch and 10-inch rough-ins. In general, 10-inch rough-ins are more likely to be found in older houses. On the other hand, the 12-inch models are typical for modern bathrooms. Overall, 12-inch rough-ins are more common, so you may have more trouble finding a 10-inch toilet option if you do have a 10-inch rough-in.
Can I Replace Toilets With Bigger Rough-in Sizes with a 10-Inch Rough-in Toilet?
Unfortunately, if you have a toilet with a bigger rough-in size you can’t install a 10-inch rough-in. You are going to have to measure the size of your rough-in and find a toilet that size because otherwise, the parts won’t connect.
With all the various features this model has to offer, these toilets make great choices for everybody. They are designed sturdy and durable, meaning you don’t have to sacrifice high-quality design for compact space.
