Rough-in Measurements Explained
It is important to understand what a rough in is and how to measure it if you’re buying a toilet. The rough-in measures the distance between the wall and mounting holes on the toilet flange. Toilets typically have a rough-in of 25 cm, 30cm, or 36cm. In the US, the most common is 30cm.
Even though you can replace a 36cm rough-in with one 30cm in length, there will still be a gap of 5 cm. Installing an offset toilet flange can resolve the problem. You might also need to replace your old commode by installing an offset toilet flange.
There Is A Difference Between Rough-ins
A majority of toilets have a rough in of 10 to 30 cm. However, it is rare for toilets to have a 36-cm rough-in. Because it must allow for a shorter distance, a 25 cm version will be much thinner. However, a 36 cm rough-in is more expensive and can have a greater impact on the cost of your new toilet.
Most people will have a 25 cm rough in on their toilet if they have a small bathroom or an older house. There is a good chance the bowl you select will be round.
Because it can accommodate toilets of any style and type, a 30 cm rough-in is most popular. Be sure to measure your toilet before you buy a new one.
Be aware that a 36 cm rough in is usually only suitable for older homes and bathrooms. Although your options for a new toilet may be limited, there are still many great options, such as the ones mentioned here.

A Buyer’s Guide For Everybody
These are seven things to keep in mind when purchasing a 36 cm rough-in toilet.
Water Consumption
A toilet that uses too much water has two drawbacks. It will increase your monthly bill, which can add up to significant amounts at the end. It is also not environmentally friendly, and some models are banned in certain states. However, it is important to ensure that the model you select can withstand low water consumption.
Bowl Shape
There are two types of toilet bowl shapes: round and elongated. Both have their benefits.
Although they are more comfortable, longer bowls take up more space. Sometimes, even a few inches may be too much. Round bowls are great for small bathrooms, but they are less comfortable.
Toilet Price
Whatever you are looking to purchase, the price is always an important factor. A new toilet is a long-term investment. It’s worth spending a little more than you originally planned. It is important to determine what features you require, as this will impact the cost. You won’t be disappointed if you pay a lot for a toilet that has remote control, LED nightlights and seat heat adjustment.
One-Piece Vs. Two-Piece 36cm Rough-In
Each style has its pros and cons. Modern bathrooms will love one-piece units. They look elegant and luxurious. Because they are not susceptible to dirt, they are easy to maintain. They are usually leak-proof because they come in one piece. However, if one of the toilets breaks down, the entire unit will need to be replaced. They are also heavier and more difficult for you to transport to the installation site.
Although two-piece units tend to be cheaper, connecting the tank and bowl increases the installation time. These units are larger and more susceptible to dirt making them not suitable for small bathrooms. A two-piece unit can be a better option if you’re looking for a more affordable solution.
Glazing
Glazing is an important consideration because we use the toilet every day. A smooth surface will allow waste to flow down the toilet and not stick. This will reduce the amount of maintenance required and make the toilet more convenient.
You can search for labels like EverClean and Cefiontect if you’re looking for a unit that has a high-quality glaze. These units have been tested numerous times over the years.
Accessibility
Accessibility is an important consideration, especially for families with young children, the elderly, and those with disabilities. Look for an ADA-compliant toilet if you want to ensure that your toilet is accessible. These units have higher bowls which help to relieve tension from your joints while you sit.
Trapway
Different units may have different trapways. But what’s the difference? A large trapway can allow the toilet to push more waste. However, this is not always necessary. Larger trapways are more costly, but standard trapways are sufficient for most people.
Measurement Tips
Four measurements are required before your 36 cm rouch in toilet can be installed.
. Distance Between The Back Wall And The Toilet Flange
When measuring from behind the wall make sure you center the toilet bowl flange at least 30 cm away from the wall. This rule is generally applicable to toilets that have a rough-in of this size. However, if your model is not the same, be aware.
. Distance Between The Center Of Unit And Sidewall
Because it measures the distance between your toilet and any fixture on either side, this measurement should not be less than 38cm. If the tub is located next to your commode it should be at most 38 cm or more.
. Distance Between The Toilet And Other Fixtures
The measurement may vary from one country to another as it depends on the standard distance of local plumbing codes. At a minimum 53 cm clearance is required if your area has plumbing requirements that are below IPC. If you live in an area that has UPC, however, you will need at most 61 cm. This is the distance between your toilet’s front and any other obstructions, such as a wall or door.
.
Placement of water supply line
Measure six inches from the left to the closet flange’s center. Next, measure seven inches above the floor to determine the ideal location for the water supply line. You might have to make some adjustments if the water supply line is too high or low. This could lead to very unpleasant results. You can go up to six inches above the floor but no lower.
