How to Fix Gap Between Toilet and Wall Step by Step Guide

Step 1: Identify the Problem

Before you can fix the gap between your toilet and wall, you need first to identify the problem. Two main problems can cause this issue: either the wax ring seal has failed, or the bolts that hold the toilet to the floor have become loose.

The writer is suggesting that if you’re not sure what the problem is with your toilet, you should try wiggling it back and forth. If the toilet moves, it’s probably because the bolts are loose. If the toilet doesn’t move, the problem is probably with the wax ring seal.

Step 2: Measure The Gap

The next step is to measure the gap between your toilet and the wall. You’ll want to use a tape measure for this to get an accurate measurement. Once you have the measurement, you’ll need to decide how you will fill the gap.

Step 3: Choose Your Method

There are a few different ways to fill the gap between your toilet and the wall. One option is to use caulk. This flexible sealant can be applied easily with a caulk gun. Another option is to use expanding foam. This is a more permanent solution, but it can be more difficult to apply.

Step 4: Use Caulk

If the gap between your toilet and the wall is less than ½ inch wide, you can use caulk to fill it in.  First, clean out the area around the gap with a putty knife or other sharp object. This will help the caulk adhere better. Next, run a bead of caulk along the length of the gap. Use your finger to smooth it out, and then wipe away any excess.

Step 5: Use Expanding Foam

For wider gaps, you can use expanding foam. Just be sure to use a safe product for both indoor and outdoor use, as some expanding foams can be corrosive. Also, be sure to wear gloves when using expanding foam so that it doesn’t come into contact with your skin.

Step 6: Use a Toilet Flange Repair Kit

If the gap between your toilet and the wall is more than ½ inch wide, you’ll need to use a toilet flange repair kit. This kit will include an extension ring and new bolts and nuts. To install, first remove the old bolts and nuts from the flange. Next, place the extension ring over the flange to flush with the wall. Finally, bolt the new bolts and nuts into place.

Step 7: Fixing a Loose Toilet

If your toilet is loose and rocking, this can also cause a gap between the toilet and the wall. You’ll need to tighten the bolts that secure the toilet to the floor to fix this. Start by removing the caps on the bolts, and then use a wrench to turn them clockwise until they’re tight. Once all the bolts are tight, replace the caps and flush the toilet to check for any leaks.

Step 8: Test It Out

Once you’ve filled the gap between your toilet and the wall, it’s time to test it out. First, flush the toilet a few times to see if any water leaks. If there are no leaks, then you’re all done!

If there are leaks, you’ll need to go back and check the caulk or silicone to make sure it’s properly sealed. If there are still leaks, you may need to use a different type of sealant.

Step 9: Call a Plumber:

If you’re still having problems with the gap between your toilet and the wall, or if you’re not comfortable trying to fix it yourself, your best bet is to call a professional plumber. They’ll be able to diagnose the problem and make sure that it’s fixed properly.

Now that you know how to fix gap between toilet and wall, it’s time to get to work! If you’re using caulk, clean out the area around the gap first. Next, run a bead of caulk along the length of the gap and use your finger to smooth it out. Finally, wipe away any excess, and you’re all done!

If the gap is too wide for caulk, you can use expanding foam or a toilet flange repair kit. Just be sure to follow the instructions carefully so that you don’t cause any further damage. And if you’re still having problems, don’t hesitate to call a plumber.
