The main issue with bathrooms nowadays is that they come last into blueprints. Therefore, they are made by using leftover space. That is the reason why some bathrooms nowadays are small and lacking space. Still, installing a 10-inch rough-in toilet will give you a few extra inches. They will most likely be closer to the wall, freeing up some extra space in front of them. Even though it may not seem like a big deal, a few inches of free space can come in handy.

10-Inch Rough-In Toilets: Buying Guide
What Is a 10-Inch Rough-In Toilet?
The size of the rough-in is quite important. It will come in handy to your plumber when it comes to installing the main drain pipe. Remember, once it has been done, it will be really difficult to change. Therefore, you must plan everything and go it right the first time. Toilets most frequently come with a 14”, 12”, and 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.
Should I Buy a 10-Inch Rough-In Toilet?
If you are thinking about whether you should get a 10-inch rough-in or not you came to the right place. By getting a 10-inch rough-in you will most likely gain a few inches of free space. For instance, you may need just those couple of inches to fully open a cabinet or shower door. Furthermore, it is a good option if you have an old house and want to replace a 10-inch toilet. Still, if you don’t need any of these, you should go for a 12-inch rough-in. 12-inch rough-in toilets are better since there are a lot more buying choices.
How to Choose a Perfect 10-Inch Rough-In Toilet for You?
Type of Toilet
There are a few things you need to know before deciding which type of design you will buy. Now, there are one-piece and two-piece designs. One of the differences is that the one-piece toilets are smaller than the two-piece ones. Plus, they are much easier to maintain as they don’t have hidden places. But still, the two-piece models come with the bowl separated from the tank. Their biggest advantage is that they are much cheaper than their counterparts. However, you may experience shipping problems with them.
Water-Saving
Not a lot of people realize that their toilets can have a huge impact on their 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.
Right Height Selection
Most manufacturers often use terms such as comfort height, right height, and so on. This can sometimes be very confusing to some people. If not, it probably represents the distance between the edge and the floor. That could be a problem because by adding a seat, you will be a few inches higher. The standard height for most toilets is around 16 inches.
Exact Rough-in Measurements
Not many people know exactly what a 10-inch rough-in means. That is the distance between the center of the master pipe and the wall. So, it is essential to measure this properly. If you end up closer or further from the spot your toilet should be at, you won’t be able to install the toilet. What’s more, just one inch can make it impossible for you to install the system.
Type of Flushing System
This factor is something you would want to consider when buying a toilet. The main reason is that this determines the efficiency and flushing power. More powerful systems will keep your bowl cleaner and are less likely to clog. This way you won’t have to flush more times until all the waste is gone. Furthermore, they will help you save some water and money.
Standards of Water Restrictions
Remember, you must check the standards of water restrictions in your state. Some states such as Texas and California don’t allow toilets that use more than 1.28 GPF. Most other states are fine with 1.6 GPF. There are even tanks with a capacity as small as 0.7 gallons. But, with such systems, you will have to flush multiple times to remove all the waste. If you are an online purchaser you can find that info easily. Still, if you are at a store, you should ask them to do the test for you.
Consideration of the Bowl
Another essential thing to consider is the type of bowl. Most bowls come in two most common shapes; round and elongated. The round-shaped bowls are better for those who want to save up some more space. With the elongated bowl, your legs are way more naturally positioned. So, the elongated ones are better if it is the comfort you need. Still, you should know that kind of material the bowl is made of. Plus, note that some manufacturers offer antibacterial finishes to enhance hygiene.
Comfort of Seat
No one wants to feel uncomfortable while sitting on a toilet, right? Therefore, you should consider the comfort of the seat while purchasing. But, there are tons of products that don’t come along with the toilet seat. A good example of that is the KOHLER Cimarron K-3851-0. Still, things like seat comfort can significantly improve the experience.
Thematic Choices of Bathroom
Aside from the performance, it is also important to make sure your toilet looks good. Your toilet should not stick out from the rest of your bathroom. Mostly because it will make your bathroom way less appealing to the eye. Most systems out there are white, linen, or bone color. However, you can easily find the brown and black shades as well. Therefore, pick the color that perfectly fits your idea. Certain people tend to go for the darker toilets because it will make the dirt less visible. That is a very bad idea! Not only will it not help, but it could even lead to some fatal infections and damage your health.
Warranty and Certifications
No matter what kind of product you are buying, the warranty is of very big importance. Warranty is the best way for a company to ensure the quality of their toilets. Of course, a longer warranty means a bigger price but is also better. The standard warranty for many products out there is about 1 – 3 years. Most toilets on this list have either a 1-year or 2-year limited warranty.
Price
While buying a 10-inch, or any other kind of toilet, we must take our budget into account. However, most people, when buying a 10-inch rough-in, are replacing the old one. They often tend to do that because some part of the old one is damaged. If that’s the case, you may not have to replace the whole toilet. You could just replace the damaged part, as it would be much cheaper and easier.
Still, that can pretty much depend on the age of the toilet. If your toilet is very old, it could be way harder to find replacement parts. Therefore, the replacement parts can be a lot more expensive than expected. Aside from all that, the new toilets offer way better performance as well as efficiency. So, if it’s difficult to find the parts for your old toilet, there is no reason not to consider buying a new one.
Installation and Maintenance
How to Install a Toilet (10-Inch Rough-In)?
Before even thinking about the installation it is important to measure everything properly. To figure out the rough-in dimensions, you can use a measuring tape. Once you finish that part, it is time to start the installation process. You are going to need tools such as wrenches, hacksaw, putty knife, and wax ring. An empty bucket and a pair of rubber gloves could also really come in handy. First off, you must disconnect the water supply from the toilet you want to replace. After that, to make sure the tank is empty, you have to flush it a few times. Now, unscrew the bolts and carefully remove the seat cover and the old toilet. Take your new toilet, attach it with the provided bolts, and connect the water supply. Finally, just flush a few times to fill the bowl.
Maintenance Instructions
One-piece toilets are far easier to maintain and keep clean than two-piece ones. Still, if you knew, you could easily install any 10-inch rough-in system. However, before you buy one, make sure it has a reputation for low-maintenance. Some toilets with powerful flushes can get rid of all the waste with just one flush. Another thing that will keep your toilet clean is the antimicrobial surface.
