The toilet rough-in often refers to the distance from the wall behind the actual toilet to the center of the pipe where the waste goes. Most toilets fall in the “12-inch rough” category.

In older homes and special situations like tight bathroom spaces, 10-inch rough-in toilets will allow for easier installation and bathroom appeal.

Despite their compact design, top-rated 10-inch rough in toilets use similar flushing mechanism of standard toilets.

Before you go on to replace your toilet, measure the distance from the wall or have a professional do it for you. It’s important to measure from the wall (not from the molding) to the bolt caps.

In order to choose the right rough in toilet, you should consider such aspects as the toilet configuration type, water efficiency, seat height and bowl shape.

After collecting data from various 10-inch rough-in toilet reviews and resources, we compiled a resource that’ll help you make a smart decision.

Things You Need to Know Before Choosing a 10-inch Rough-in Toilet

Are you looking for a toilet that will fit in a smaller bathroom or any other tight space in your home?

Well, you need to choose a product of the right size to save on space. In this regard, a 10-inch rough-in toilet would be a great choice.

Additionally, such a toilet will come in handy for homeowners who are replacing a traditional toilet with a 10-inch rough-in. As you may be aware, these toilets are often considered to be old and outdated. As such, they are not so common in the market today.

This makes the choice of the best 10-inch rough-in toilet a bit challenging. If you are looking for the right ten-inch rough-in toilet for your home, here are some of the main considerations you should make:

1. Flushing System Efficiency

As you will learn later in this guide, it is now a requirement by the law for modern toilets to be efficient on water.

As such, toilets are now required to use a smaller amount of water per flush to push away solid as well as liquid wastes down the sewage line.

As the various manufacturers strive to comply with this requirement, their products tend to differ when it comes to waste flushing efficiency. This is why you need to select carefully so as to end up with a product that is both efficient on water and flushes wastes more efficiently.

In order to make the right decision, you should consider how well the flush system cleans the bowl and pushes the waste down the drain line. In this regard, these are the two main 10-inch rough-in toilet flushing systems you should consider:

Gravity-Feed Flush System

Of the two main flush systems used in toilets today, this is the commonest and more affordable. In its functioning, the flush system relies on the force of gravity to flush the waste and push it down the sewage line. As such, they feature a rather simple design.

Basically, these products have a flush valve that allows water to drop from the tank to the bowl and clean it—mainly using gravitational acceleration.

The flushing performance of such toilets mainly depends on the size of the flush valve. As a rule of thumb, you should opt for a 10-inch rough-in toilet with a flush valve larger than 3 inches.

As opposed to the pressure-cooker models that require higher household water pressure, these toilets can work with as low as 10 pounds per square inch of water pressure. The relatively weaker gravity-feed toilets are known to clog every now and then.

Pressure-Assisted Flush System

As far as the flushing efficiency is concerned, pressure-assisted toilets are superior to those that use a gravity-feed flush system. As the water flows from the home plumbing system, it compresses air in the water storage tank of the toilet.

This pressure is then used to flush the waste on the bowl more forcefully. As such, toilets with this flush system are only suited for homes with a water pressure of at least 25 pounds per square inch.

To check whether the pressure in your plumbing systems meets this minimal requirement, you may need to connect a $10 gauge to the outdoor spigot.

Although these toilets are known to be more efficient at flushing human wastes, they are noisier in operation. Again, these products are costlier to buy, as compared to gravity-feed toilets.

2. Water Efficiency

Did you know that the toilet in your house uses more than 30 percent of the water consumed in your home?

Actually, an increasing number of house owners today are replacing the toilets in their homes in an effort to boost water efficiency.

Whether the toilet is to be used for a toilet replacement project or to be installed for the very first time, it needs to be water efficient.

According to a 1995 requirement by the Department of Energy, toilets installed in the country should have a consumption of less than 1.6 gallons per flush.

Most of the toilets reviewed in this guide are compliant with this requirement and some even meet the stiffer standard imposed in California—toilets to be installed in the state should not have a water consumption of more than 1.28 gallons per flush.

Additionally, the most efficient 10-inch rough in toilets that meet the California standard features a WaterSense label.

3. Seat Shape

Just as is the case with the standard 12-inch rough-in toilets, the shape of the seat on these products is not only meant for enhanced aesthetics.

The shape of the seat on your preferred 10-inch rough-in toilet will, to a great extent, determines how comfortable it is.

When choosing the best 10-inch rough-in toilet, these are the two main toilet seat shape options you should consider:

Round Seats

Most traditional-style toilets are equipped with round toilet seats. If this is the type of toilet you need to incorporate into your bathroom decor, it is advisable to opt for the ADA compliant models.

As compared to the elongated seat toilets discussed below, toilets with round seats will save you some space.

As a matter of fact, round toilet seats are 3 to 6 inches smaller than similar elongated seat toilets. If you are installing a 10-inch rough-in toilet because of space concerns, a round seat toilet will save you even more space.

In smaller bathrooms, this small difference can mean a lot. Again, round seat toilets are considered to be a great choice for homes with children who have just completed potty training.

Elongated Toilet Seats

As far as comfort and ADA compliance are concerned, 10-inch rough in toilets with an elongated seat are the best option.

As such, toilets with elongated seats are more preferred for public bathrooms. Similarly, elongated toilet seats are recommended for the elderly, disabled and people with back problems.

This may be attributed to the fact that elongated toilet seats are more comfortable to use. However, this type of toilet seats is costlier and requires more installation space. As such, elongated toilet seats are not suited for smaller bathrooms.

Ready to Buy a 10 Inch Rough In Toilet?

Currently, there are not so many 10-inch rough-in toilets on the market, when compared to the standard 12-inch toilets.

However, choosing the right model for your bathroom can be challenging, if you do not know what to look for.

Just as is the case with other toilet types, a higher price does not guarantee you higher performance and an efficient 10” rough in toilet.

To get the right product for your upcoming installation, it is advisable to consider the various aspects discussed in this guide.

Other than that, your personal preference may also play a role in your final choice.

Regardless of the toilet features you are looking for, our review will help you choose the best 10-inch rough-in toilet that money can buy.
