The 10-inch Rough-in Toilet Buying Guide

Getting a 10-inch rough-in toilet is not so different from getting any other toilet because most of the features you will consider are characteristic of any good toilets.

Here are some other factors to consider aside from the rough-in.

Water consumption

Most people do not know the effect a toilet choice can make in how much money they save in water bills every year. There are different types of toilets on the market with varying types of flush. According to the Environmental Protection Agency, a toilet should not use more than 1.6 gallons of water for every flush.

However, some toilets use significantly less than this standard volume, and these toilets are excellent water-saving options. Using a dual flush toilet can also help save water as you can use different quantities of water for different types of waste.

Before buying a toilet, therefore, look at how much water it consumes per flush.

Bowl Height

The height of a toilet affects how comfortable using it will be. Toilets with a height below the standard value are generally more suitable for shorter people, while toilets with height above the standard value are suitable for tall people. You should consider the height of the people that are going to use the toilet when making your decision. Sit on the toilet before purchasing it, so you can experience the feel of using it.

Bowl Shape

The shape of a toilet bowl is an underrated feature that is easily ignored by most toilet users. The bowl shape affects the space-saving capacity of the toilet as well as how comfortable it is to use. Toilets with round bowls are better fits for small bathrooms. Elongated toilets, on the other hand, are more comfortable to use because your legs are more naturally positioned while using it. Choose whichever fits your needs more.

Flushing system

The type of flushing system a toilet uses should also be on your list of considerations because it determines the flushing power and efficiency of the toilet. A toilet with a powerful flushing system could help save water, as it will not require multiple flushing to remove all the waste.

It is imperative that you go for a system that will make flushing easy for you. A toilet is meant to provide relief, so using it should not be tedious.

Installing a 10-inch Rough-in Toilet

If you have done your research and decided on which toilet to get, the next thing to do is install it. Most of these 10-inch rough-in toilets are easy to install, so it is smart to save money by installing the toilet yourself instead of hiring a professional. However, it is crucial that you get it right the first time around so as not to pay more than the amount you are trying to save.

Here are simple steps you should take to install your toilet:

  • If your bathroom does not have a drain for the 10-inch rough-in toilet, you will have to install a drainpipe.
  • Place the wax ring on the main drain opening.
  • The bolt-holding ring should be attached to the floor close to the wax ring. Then put the bolt in a way that the threads are facing the toilet you want to install.
  • Gently lower the toilet to align with the wax ring and bolts. Ensure that the wax ring remains in place, or you could have a big leak in your hands.
  • After placing the toilet on the bolts and wax ring, use the nuts to tighten the setup.
  • Assemble all the other parts of the toilet that have not been installed.
  • Make sure you check the toilet for any form of a leak, and then you are good to go.

Frequently Asked Questions (FAQs)

Most people do not pay attention to the rough-in of a toilet, so when the topic comes, there are usually some questions that follow. Here are some of the common questions asked.

Q. Why does the rough-in have to be 10 inches?

A. This question comes up when you tell someone about 10-inch rough-in toilets. The few extra inches that a 10-inch toilet gives could be what makes your shower door or your cabinet door open entirely. Apart from this, bathrooms in most older houses are built to accommodate smaller toilets, so if you live in such a house, you need to have a toilet with a 10-inch rough-in.

Q. How can I measure the rough-in of a toilet?

A. The rough-in of a toilet is the separation between the toilet and the middle of the outlet pipe. The outlet pipe is where waste passes out of the toilet. Most toilets nowadays come with a 12-inch rough-in. In cases where the outlet pipe is further away or closer to the wall, a 14-inch or 10-inch rough-in toilets are used, respectively.

The measurement is pretty straightforward — all you have to do is place one end of your measuring tape on the wall and then measure the distance to the bolt caps. You should note that the measurement should not be taken from the molding but the wall.

Q. What are the advantages of using a 10-inch rough-in toilet?

A. Using a toilet with a 10-inch rough-in has many advantages. Here are some of the benefits these toilets have over others:

  • The most obvious advantage is the fact that these toilets save space. The extra space that this toilet offers will add to the convenience of using your bathroom. This is especially true for houses with small bathrooms.
  • A 10-inch rough-in toilet can use the same toilet technology used by toilets with a 12-inch rough-in.
  • Apart from the different rough-in, these toilets can be installed like most other toilets.

Q. What are the disadvantages of using a 10-inch toilet?

A. Toilets with a 10-inch rough-in are excellent toilet choices, but they still have their flaws. Let us consider some of the disadvantages of using these toilets.

  • Toilets are not as commonly used as other toilets like the toilet. This makes it a little challenging to get spare parts when it needs to be repaired.
  • These toilets generally have smaller toilet bowl than toilets with other rough-in sizes. This has become an issue for some users, as they complain that the small bowls are not comfortable when using the toilet.

Q. How do I maintain my 10-inch rough-in toilet?

A. A toilet is one of the most used pieces of hardware in the home. You have to take good care of it, so it will last as long as possible. Let us take a look at some of the common issues that could come up.

  • Leaks – It is essential that you check your toilet regularly for leaks so that you will be able to deal with them on time. Leaks sometimes occur when the gasket or wax ring holding the toilet to the floor starts to degrade, allowing water to pass through. Leaks can damage the floor so they should be fixed as soon as possible.
  • Blockages – Blocked toilets are common, especially if you are using toilets with a weak flushing system. A blocked toilet cannot be used until the passage has been cleared. You can use a plunger to solve this problem, but if this does not work, quickly contact your plumber.
  • Stability – A wobbly toilet is uncomfortable to use, and the wax ring could deteriorate, leading to leakages. A wobble can be caused by poor installation or if the nut holding the toilet down has come loose. It is important that you secure your toilet tightly to prolong its lifespan.

In Conclusion:

The need to pass out waste regularly has made toilets one of the most important pieces of hardware in the household. It is, therefore, essential that you pick a toilet that fits perfectly into your bathroom. When considering what toilet to purchase, you should not overlook the rough-in as it is an important factor, especially for houses with small bathrooms.

Toilets that have a rough-in of 10 inches are brilliant choices for those with small bathrooms because they help you manage the small space perfectly. While considering the rough-in, however, do not forget to consider other features as well, like the seat height, water consumption, and the flushing system, as they are equally vital for picking a good toilet.

If you are going shopping for a 10-inch rough-in toilet, and you do not know which one to get, this review is a good place to start. Buy any one of the toilets mentioned here, and you’ll be sure to get a good one.
