How to Make Your Toilet Level

Once your toilet has already been installed and begins to wobble when you use it. Finding the cause of the problem is straightforward, but it is a lengthy procedure. But don’t worry, you don’t need to be an expert mechanic to fix the shaky toilet.

You may just need to make minor modifications based on how uneven your toilet is. In rare circumstances, you may need to disassemble the toilet. If you have the required equipment, you can easily level it all by yourself.

Step 1: Examine the Toilet’s Current Level

Before you start correcting the problem, make sure your toilet is level. Also on top of the toilet tank, install a short level, including a two-foot level. Then raise the level till the bubbles are sandwiched between the vial’s two lines.

You can assess how unlevel your toilet is by calculating the length. Between the toilet and both the bottom and top of the level. It should give you a fair idea of the number of shims you’ll need.

Step 2: Removal of the Toilet

Obviously, replacing the toilet is a wet job. You might find it more comfortable to perform this while wearing gloves. Adjust the water supply and remove the tank lid. And place it in a secure spot where it won’t be broken.

Ensure that you flush the toilet to eliminate as much water as possible from the tank. Then, using an old towel or a moist super-absorbent sponge, suck any remaining water from the toilet. Shut off the water and place a bucket beneath the faucet to catch any residual water.

Unbolt the toilet first, then remove it from the floor. Two bolts should be used, on either side of the toilet. The majority of these bolts are protected by a plastic covering.

As a consequence, remove the cover and unscrew the bolts. Then carefully raise the toilet high up and away from the bolts. It’s preferable to use thick plastic sheets or waste bags to protect it.

Step 3: Examine the Wax Seal and the Flange.

To verify if the flange and wax seal has to be changed, you’ll need to replace the wax seal.

Even if wax seals are inexpensive, it’s a good idea to change them as soon as possible. If you like, you can use a foam ring instead of a wax seal.

Step 4: Replacing the Toilet

You may replace the toilet once you’ve resolved all of the concerns. With flange, loose bolts, and wax seal. If the toilet isn’t level due to an uneven floor, you’ll must use fasteners to level it:

Replacing the closet bolt with a lock washer. Set the plastic ring or wax seal in place. You might choose the foam ring over the wax ring because wax rings can be harder to place.

Connect the toilet to the bolts once again. It’s important to have a second pair of eyes to double-check. That the toilet is positioned correctly over the bolts.

If the flooring is the issue, shims can now be placed beneath the low side of the toilet. The shims must not be made of wood since they will deteriorate over time. There are shims made specifically for use beneath toilets. They’re made of plastic, are tiny, and stackable, offering them a practical option.

Step 5: Check the Toilet’s Level Once More

Examine the toilet’s level once more to ensure that any alterations made were effective. After that, the toilet should be fixed to the floor. It’s important to remember to put the bolt cover on since it tends to keep the bolt in place. Attach each side a little at a time instead than pressing one side at a time.

Replace the tank lid with its original position after removing the extra closet bolt. Restore the water supply and flush the toilet a couple of times to make sure it’s working.

Your toilet ought to be wobble-free and operating correctly at this time. After that, mop up any spills. For a complete look, you might wish to use caulk or putty all around the toilet’s base.

These steps you can follow to level your toilet.

Should a toilet sit flat on the floor?
