How To Shim A Toilet In Less Than 1 Hour?

No one likes a wobbly toilet. Not only is it unsightly, but it can also be dangerous if not shimmed properly. Although it may seem like a daunting task, shimming a toilet is actually quite easy and only takes about an hour to complete. Here’s what you’ll need:

  • A putty knife
  • A hammer
  • A leveler (optional)
  • 3/4″ to 1″ wide metal shims
  • ALEENE’S® Original Tacky Glue™ or similar glue  

Following steps:

  • Step 1: Turn Off the Water Supply The first step is to turn off the water supply to your toilet so you don’t flood the bathroom while you’re working. There should be a shutoff valve located on the wall behind your toilet near the base. If there isn’t a shutoff valve, you’ll need to turn off the main water supply for your home. Once the water is turned off, flush your toilet to empty out the tank.  
  • Step 2: Inspect the Flange The next step is to take a look at the flange (the part of the toilet that connects to the sewage pipe). If the flange is higher than the floor around it, you’ll need to shim under the toilet base so it sits level. If the flange is lower than the surrounding floor, you’ll need to add a spacer on top of it before shimming under the toilet base.  
  • Step 3: Add Glue and Shim Once you’ve determined where your shims need to go,Apply glue to both sides of each shim before placing them in position under or on top of the flange (depending on what step 2 told you). Press each shim firmly into place and wait for the glue to dry completely (about 30 minutes).
  • Step 4: Turn On Water Supply and Test Once everything has dried, turn on your water supply and let your tank fill up. Once full, flush your toilet a couple times to make sure everything is working as it should be. You may need to adjust your shims slightly if there’s still some wobbling going on. And that’s it! You’ve now successfully shimmed your toilet and can enjoy having a sturdy potty once again.

What can I use instead of toilet shims?

If you’re in the process of shimming a toilet, there are a few things you can use in place of traditional metal or plastic shims. Wood shims are a good option, as they’re strong and easy to cut to size. You can also use old towels or rags; simply roll them up and wedge them under the toilet base until it’s level.

Another option is to use a rubber mat or piece of cardboard; both will provide a stable surface for the toilet to sit on and will help to prevent slips and leaks. Whichever material you choose, make sure it’s firm and won’t compress over time. With a little creativity, you can find an effective shim for your toilet that won’t break the bank.

Can you shim a toilet to make it level?

One of the most common complaints about toilets is that they are not level. This can cause a number of problems, from leaks to difficult-to-flush toilets. While it may seem like a daunting task, shimming a toilet is relatively simple and can be done with just a few tools. The first step is to determine where the toilet needs to be shimmed. This can be done by placing a level on the toilet bowl and seeing where it is not level.

Once you have determined where the shims need to go, the next step is to measure and cut the shims to size. Toilet shims are typically made of plastic or metal, and can be found at most hardware stores. After cutting the shims to size, the final step is to install them under the toilet bowl. With a little time and effort, you can easily shim a toilet to make it level.

How do you make a toilet shim?

A shim is a thin piece of material, often wood or plastic, that is used to fill in small gaps or spaces. Toilet shims are commonly used to level out a toilet bowl that is not sitting level with the ground. This can be due to a slightly uneven floor or a problem with the bowl itself. Making your own toilet shim is a relatively simple process.

First, measure the amount of space between the bottom of the toilet bowl and the floor. Then, cut a piece of wood or plastic to fit this space. It is important to make sure that the shim is level beforeinserting it into the gap. Once the shim is in place, you can use a screwdriver or hammer to gently tap it into place. Once the shim is level with the ground, your toilet should be properly supported and stable.

How do you speed up a loose toilet?

A loose toilet can be a frustrating problem, but there are a few simple ways to fix it. First, check to make sure that the floor bolts are tight. If they are loose, simply tighten them with a wrench. Next, check the toilet flange to see if it is properly sealed to the floor. If not, you can use a putty knife to apply caulk around the perimeter of the flange.

Finally, if your toilet is still loose after tightening the floor bolts and sealing the flange, you may need to replace the wax ring. This is a simple process that involves removing the old wax ring and installing a new one. With a little patience and some basic DIY skills, you can easily fix a loose toilet.


A wobbly toilet is not only embarrassing but can also be dangerous if not fixed properly. It may seem like a daunting task but with these simple steps and tools, anyone can do it! In less than an hour your bathroom will be back to its original glory.
