It’s normal to leave a little gap between the toilet and the wall because you might need to remove its tank lid occasionally. Not to mention, building regulations require that there’s a 15-inch clearance between the toilet flange and the walls.
However, if the distance is too far, you need to learn how to fix gap between toilet and wall. Having a large gap between the toilet and the wall can be unsightly and a waste of space, especially if you have a small bathroom.
Several ways to fix the gap include installing an offset flange, adding tiles, or relocating the plumbing to move the toilet close to wall.
Let’s enumerate the steps below.

4 Ways to Fix Gap Between Toilet and Wall
How Far Should a Toilet Be From the Wall
Generally, the toilet hole distance from wall behind should be 12 inches. To ensure that your toilet gets the right dimensions, measure from the finished back wall to the center of the toilet flange. Now, this will give you a 1-inch gap distance between toilet and wall once the toilet is installed.
At the side wall or nearest fixture like a vanity, the minimum distance is 15 inches. You can add more inches to give more elbow room if you have a large bathroom. How much space is needed on your toilet’s front depends on local plumbing regulations.
Causes of Gaps and How to Prevent
Have you wondered why your toilet cistern not touching wall?
Following the building code of the bathroom’s fixtures can leave a gap of one inch between the toilet and the wall. It’s necessary to leave a little space to use the toilet more comfortably. To cover gap issues, you can install a rack for extra storage or insert an expanding foam.
The 15-inch toilet drain distance from wall rule is based on the old toilet models with large tanks. Now that newer models are toilets with narrow tanks, the gap becomes wider and more apparent. To avoid the gap issue, choose a toilet model that offers the least distance from back wall.
What is an offset flange and its benefits?
An offset toilet flange is a piece of fitting device that connects your toilet to the drain pipe. Instead of the straight standard flange, the offset model is angled to allow more flexibility to move the toilet tank against wall.
Why should I fix the gap between the toilet and wall?
Having a large space behind the toilet can make retrieving items that have fallen within the fixture’s vicinity more challenging. For instance, you put a shampoo bottle on top of the tank. When it falls in the gap, it would be difficult to reach out for the item.
Should there be a gap between toilet tank and bowl?
There’s usually a gap between ¼-½ inch from the tank to the bowl. More than that, and the toilet will become unsteady. You need to find a tighter fit because having a big gap can put a toll on the bolts and cause water leaks.
Now that you know how to fix gap between toilet and wall, you can upgrade the look of your bathroom. My favorite solution is the offset flange because it’s easy to install and works more efficiently in closing the gap. All solutions are effective, but pick one that suits your current budget and skills.
