The rough-in distance in the newer homes from the wall to the center of the toilet drain is 12-inch, while, older homes have a distance of anything between 10- or 14 inches. A wall-mounted toilet also needs a 10 inch thick wall to accommodate the flushing system.
Building codes are like the average allowance required between the toilet and the wall, however, if possible, the distance from the toilet centerline to the wall framing should be 18 inches to increase convenience and comfort when using the toilet.
Overall, proper toilet clearances contribute to efficient bathroom design and promote well-being for all users. Minimum clearances between the face of the toilet fixture and the wall or nearest obstruction element are at least 24” (61 cm) but are recommended to be 36” (91 cm).
The correct measurements for a toilet is at least 21 inches in the front of the toilet, 15 inches on the sides, and at least 30 inches from anything else in the bathroom.
Rough-In Dimensions for Toilets
Supply line (vertical): 8 1/4 inches of height to accommodate most base moldings. Supply line (horizontal): 6 inches maximum to either side of the toilet centerline. Discharge/drain hole from back wall: 12 1/2 inches, providing enough space to install the toilet.
Standard Dimensions of a Toilet
The most important of these measurements is the distance between the floor drain and the wall, called the rough-in. The standard rough-in dimensions for toilets is 12 inches. In older homes or small bathrooms, you'll sometimes see rough-in dimensions of 10 inches or 14 inches.
Toilet Clearances
We recommend leaving at least 21" of space in front of the toilet and at least 15" of space from the center of the toilet to a wall or another object.
The toilet should be installed with the top of the seat between 17” and 19” above the floor and located between 16” and 18” from the side wall to the center line, unless it is regarded as an ambulatory accessible toilet compartment that must be between 17” to 19” from the side wall.
Toilet tank braces can be adjusted to fit the gap between your tank and wall. Clipped on back edge of tank, under lid, braces are practically invisible when installed. Anchor your tanks with Secure-A-Tank to protect against costly leaks and repairs.
Clearance: At least 24" of space is needed in front of a shower or tub entry. Leave at least 15" of space between the shower and toilet or other obstacle.
Set-outs can vary, depending on the age of your house. Most new homes have a standard set-out of about 140-165mm, which is suited to most toilet suites.

Clearance around a water closet shall be 60 inches (1525 mm) minimum measured perpendicular from the side wall and 56 inches (1420 mm) minimum measured perpendicular from the rear wall.
Standard toilet clearance requirements state that toilets must be installed: At least 15 inches to any partition or side wall (measured from its center). 30 inches minimum away from any adjacent fixture (measured center to center). At least 21 inches clearance from a wall, fixture or door.
No, a domestic free standing toilet bolted to sanatary pipe flange on floor can be installed anywhere the sanitary pipe and mounting flange can be located. Most home toilets are just very close to a wall and not actually directly contacting a wall.
Toilet discharge hole (vertical): Drain located at floor height; distance is zero. Toilet side-to-side buffer: Measured from the center of the toilet to either side, minimum. clearance is 15 inches to any wall or other fixture; 18 inches is recommended if the bathroom layout allows for this.
#2: The Clearance From the Center of the Toilet To Any Adjacent Fixture or Sidewall. This measurement is 15 inches. That's the minimum (you can have more). So looking at the toilet, make sure there are at least 15 inches of clearance from the center of the toilet to any adjacent fixture (or wall).
Minimum sanitaryware sizes
The toilet and bidets must have a minimum space of 70cm in width and 120cm in length. If they are next to a wall, the minimum free space should be 20cm, and if there is an element on their side, they should not be placed less than 15cm away for greater usability.
So, answering the question of how much space is needed around a toilet, you'll want to leave about 38 cm (15 inches) that is measured from the centre of the toilet to the adjacent wall or fixture.
The standard measurement for space around the toilet is about 15 inches, and 18 inches is spacious for added comfort. The clearance from the front of the toilet will range depending on your local guidelines.

17″ to 19″ from toilet center to side walls for ambulatory accessible toilet compartments. 17″ to 19″ from floor to top of toilet seat for ambulatory and wheelchair accessible. Toilet flush controls must be on the opposite side of the closest side wall.
You need at least a 20 cm distance from other sanitary facilities on both sides. Leave a 55 cm space in front of the wash basin so that people have enough room to move. Toilets: Similar to wash basins, allow 20 cm on both sides for room to move. A 60 cm space is needed in front of the toilet.
Plugged at the U-pipe, the fresh water blocks sewer gases and lets them harmlessly leak out the plumbing vents. Every plumbing fixture needs to have a vent to work properly. Bath tubs, toilets, washing machines and kitchen sinks need the biggest plumbing vents.
