The toilet rough-in is important when buying a new toilet at home, work, or anywhere else. This determines the distance between a wall and the center of the flange. Let’s take a closer look at 10 inch vs 12 inch rough in toilet.
There are four types of rough-in toilets: 8″, 10″, 12, and 14″. It is easy to measure rough-in. Just follow these simple steps.
What is a 10-inch rough toilet?
If you are wondering what a 10-inch rough-in toilet is the distance between the finished wall and the floor opening is at a center distance of approximately 10-inches.
Older models often have a 10-inch rough-in. There are fewer options for toilets.
10-Inch Rough-In Toilet Pros And Cons
Pros
- You can save a lot of space
- This is an excellent choice for smaller bathrooms
- Perfect for pets and children
- You can later change the rough-in from 10 to 12 inches.
Cons
- Expensive
- Option for a lesser variation
- More susceptible to clogging
- The toilet is attached to a wall. This will increase sweating, dampness, and mold growth in humid areas.
What is a 12-inch Rough-In Toilet?
If you ask “What is a 12-inch rough-in toilet?”, the answer is that the finished wall and the center gap between the floor flange and the toilet are approximately 12-inches.
Today, rough-in toilets measuring 12 inches are a standard feature and there are many more options.
12-Inch Rough-In Toilet Pros And Cons
Pros
- Less prone to clogging
- Increased flushing power
- Ideal for everyone
- It can be used in small and large bathrooms
- There are many options for toilets
- No sweat or damp tank
Cons
- A toilet that is 12 inches or larger cannot be replaced with a 10-inch toilet.
10-Inch vs 12-Inch Rough-In Toilet
The above description shows the differences between the 10 and 12 rough-ins as well as the pros and cons.
The measurement between the wall and the center of the toilet’s flange is the first point, 10-inch VS 12-inch.
The 12-inch rough-in refers to the standard size of the rough-in, whereas 10 inches is the measurement for the old model house.
There are fewer options for 10-inch toilets. We have more options with 12-inch toilets, from a one-piece to a two-piece, round or elongated, and chair height to standard, along with water-efficient performance.
Toilets that are 10-inch rough-in have a higher likelihood of clogging, while 12-inch rough-in toilets or larger are remembered for their ability to clean up easily.
You will have problems if you live in humid areas. Not so with a 12-inch rough-in. They use about 1.6 GPF each flush and are 10” rough-ins.
They now only use 1 to 1.28 GPF water thanks to the 12” era.
If you need to exclude the toilet or another item, I can help you. A rough-in toilet 10 inches in diameter can be converted to a rough-in toilet 12 inches in size, as I mentioned previously.
Is it possible to replace a 10-inch rough-in toilet with a 12-inch rough-in?
You can. There are many ways to do it. A gap of 2 inches between the rare toilet wall, and the drain outlet center is 10-12 inches. This is not the result of flushing.
You can replace a 10-inch rough-in toilet with a 12-inch rough-in toilet by using an Offset Flange.
A flange connects the toilet flush outlet and the main drainpipe. To create a tight seal, the flange should be installed at least 1/4 inch above the floor.
An offset Flange is an adaptor that allows you to transfer between rough-in and finished without damaging the floor. You can also change the direction.
How to Install an Offset Flange
- The drain opener’s size should be measured in inches, either 3″ (or 4″).
- Choose your preferred size Offset Flange from 10-14″ in stock. Wax ring for tight seal and bolts.
- All water supply lines connecting to this figure should be turned off.
- In order to remove the tank lid, flush the tank thoroughly and use a sponge to absorb any remaining water.
- Take an old towel/cloth.
- Remove the old toilet from the cloth and place it on top.
- Then, remove the wax ring and clean the area around the base.
- Place the new Offset Flange in place of the old one.
- Attach the bolts to the toilet by placing the wax ring.
- Connect the water line to your computer and turn it on.
- Flush the toilet tank once you have filled it. This will then allow you to check for leakages.
How do I know if my toilet is a 10 or 12 rough-in?
As mentioned, rough-in is the measurement of the space between the rare wall of a toilet and the center flange or drain opener.
Follow these simple steps to determine if the toilet is rough-in or 10″. You will need a measuring tape before you can do that.
Floor Mounted
- First, measure the drain opener and then determine its center point and mark it.
- Then, measure the distance from the wall to where the bolt caps are located at the base of your toilet. This allows you to seal the system or tighten it.
- You should always have rare bolts on hand in case you have more than two caps.
- When measuring a stud wall don’t forget the width of the solid walls
Corner Toilet
- Start by tracing the tape along both sides of the toilet until you reach the middle of the bolt caps. This will help you to identify exact locations.
- Draw perpendiculars starting at both points.
- The rough-in is the point where both points overlap.
Is the 12-inch rough-in standard for toilets?
There is no standard size for rough-in toilets. Toilets are most commonly rough-in at 10 to 12 inches. However, there are toilets that have rough-ins of 8 or 14 inches.
Toilet manufacturers design toilets that fit different sizes of rough-in so that every person can have a toilet that fits their bathroom.
Make sure you measure the space that the toilet will need when shopping for a toilet. This will ensure that the toilet fits in your bathroom. You can either measure your bathroom yourself or hire a professional to assist you.
Wrapping Up
There are four types of rough-in toilets. There are four sizes of toilet rough-ins: 12”, 14”, and 10′. Toilet rough-in is a critical factor to consider.
It is important to remember that a 10-inch VS 12-inch rough-in toilet refers to the distance between the wall as well as the center of the flange. I hope you are able to measure these points so that you can get the best rough-in toilet.
