Did You Know?

1. Did you know that the first flush toilet was invented by Sir John Harington in 1596 for Queen Elizabeth I of England? However, it wasn’t until the late 1800s that modern plumbing systems incorporating the flush toilet became widely available.

2. In the late 18th century, beehives were sometimes used as an early form of toilet in European castles. The waste would fall into the beehive, and the bees not only helped to break it down, but they also kept the area free from odor!

3. Japan is famous for its advanced technology, and when it comes to toilets, they’re ahead of the curve too. Many toilets in Japan come equipped with built-in bidet features, heated seats, and even built-in sound systems playing soothing music to ensure a relaxing experience!

4. The world’s most expensive toilet seat was created by designer Jemal Wright and is valued at a staggering $100,000. It is encrusted with 72,000 Swarovski crystals and is known as “Diamond Toilet Seat.”

5. In the 1980s, NASA developed a vacuum-powered toilet system for space shuttles. This unique toilet uses airflow to ensure waste is properly disposed of in a zero-gravity environment, preventing any unpleasant or messy situations!

Shutting Off The Water Supply

When faced with a rocking toilet on tile, the first step to address the issue is to shut off the water supply. This can be done by locating the shut-off valve usually located near the floor or behind the toilet.

  • Turn the valve clockwise to close it and stop the water flow to the toilet.

It is important to ensure the water supply is shut off before proceeding further to avoid any accidental flooding or water damage.

  • Locate the shut-off valve near the floor or behind the toilet.
  • Turn the valve clockwise to close it and stop the water flow.
  • Check if the water supply is shut off properly to avoid potential damage.

Removing The Toilet Bolts

To gain access to the base of the toilet, the next step is to remove the toilet bolts. These bolts secure the toilet to the flange on the floor.

Here’s how to remove the toilet bolts:

  1. Use an adjustable wrench to loosen and remove the nuts securing the bolts.
  2. Once the nuts are removed, carefully lift the toilet straight up from the base, being cautious of its weight.

Remember to take proper precautions when handling the toilet to avoid any damages or injuries.

Leveling The Toilet Base With Shims

One common reason for a rocking toilet is an uneven surface beneath it. To address this, plastic shims can be used to level the toilet base. It is important to choose plastic shims to avoid damaging the tile.

Here are the steps to fix the rocking toilet:

  • Place the shims under the toilet base in the areas where the toilet wobbles.
  • Use a level to ensure the toilet is level from side to side and front to back.
  • Adjust the shims as necessary until the toilet is stable and does not rock.

Remember to be careful when using shims to protect the tile.

“Sometimes a rocking toilet can be easily fixed by using plastic shims to level the toilet base. Just make sure to choose plastic shims and not to damage the tile. Place the shims under the toilet base where the wobbling occurs. Use a level to check if the toilet is level from side to side and front to back. Keep adjusting the shims until the toilet becomes stable and stops rocking.”

Trimming Excess Shims

After successfully leveling the toilet with shims, it is common to have excess shims sticking out from the toilet base. To achieve a neat and flush appearance, trim these excess shims using a sharp utility knife. Remember to be cautious and avoid applying excessive pressure to avoid damaging the tile. Trimming the shims will result in a clean finish, eliminating any potential tripping hazards.

Reinstalling And Tightening Toilet Bolts

With the toilet base now leveled and the excess shims trimmed, it is time to reinstall and tighten the toilet bolts. Follow these steps:

  1. Lower the toilet back onto the flange, ensuring the bolts align with the holes in the base.
  2. Once aligned, hand tighten the nuts onto the bolts.
  3. To avoid cracking the porcelain of the toilet, use an adjustable wrench to gradually tighten the nuts until they are snug.
  4. Do not over-tighten, as this could cause damage.

Remember to be cautious while tightening and follow these steps carefully to ensure a successful toilet installation.

Checking For Leaks And Repeating Process If Necessary

After reinstalling and tightening the toilet bolts, it is important to check for any leaks. Turn on the water supply at the shut-off valve and flush the toilet. Observe the base of the toilet and the surrounding area for any signs of water leakage. If there are leaks, it may indicate that the wax ring sealing the toilet horn to the toilet flange needs to be replaced. In this case, consult a professional to properly address the issue. If the toilet still rocks, even after the steps mentioned above, it may be necessary to repeat the process with additional shims until the toilet is stable and does not move.

Frequently Asked Questions

Why does my toilet rock when I sit on it?

When your toilet rocks while you sit on it, it can be attributed to various factors. One possibility is that the bolts holding the toilet to the floor have become loose, causing the rocking motion. Another potential cause is an uneven floor surface that prevents the toilet from sitting flush against the ground. Lastly, issues with the wax seal connecting the toilet to the drainage system can also result in toilet wobbling. Identifying and addressing these root causes can help ensure a stable and secure toilet experience.

What causes toilet to wobble?

When it comes to a wobbly toilet, the primary cause can often be traced back to the flange or flange bolts. The flange, which is a circular fitting that connects the toilet to the sewer pipe, can become loose due to wear and tear or improper installation. This can result in a wobbly toilet that needs to be stabilized. Additionally, the flange bolts, responsible for securing the toilet to the floor, can also become loose over time or due to excessive force applied when tightening them. Checking and tightening the flange or replacing the flange bolts are typical remedies for addressing a wobbly toilet.

Can you stick a toilet to tiles?

Yes, it is possible to attach a toilet to tiles using a reliable method. To ensure a strong bond, it is recommended to use a combination of sand and cement mix, along with applying a layer of uni-bond on the tiles underneath the toilet. The uni-bond helps enhance the adhesion of the mortar mix. After the installation, allowing the bond to cure for at least 24 hours before usage will help ensure the toilet stays securely attached to the tiles. By following these steps, the toilet can be effectively stuck to the tiles, providing a stable and long-lasting installation.

1. What are some effective ways to fix a rocking toilet on tile without damaging the flooring?

One effective way to fix a rocking toilet on tile without damaging the flooring is to use shim packs. Start by turning off the water supply and flushing the toilet to empty the tank and bowl. Place a shim underneath the toilet base on the side that is rocking. Use multiple shims if needed to level the toilet. Gently tighten the toilet bolts to secure it in place, being careful not to overtighten and crack the porcelain. Finally, trim the excess shim using a utility knife and caulk around the base to provide a finished look while also preventing any movement.

Another method to fix a rocking toilet without damaging the tile flooring is to use a toilet base extender. Similar to shim packs, turn off the water supply and drain the toilet. Remove the toilet bolts to disconnect the toilet from the floor, and then install the toilet base extender along with new wax ring. Reattach the toilet to the floor by tightening the bolts, ensuring it is level and stable. Lastly, caulk around the base of the toilet to provide a seal and prevent any rocking movement. This method is beneficial as it raises the toilet base, eliminating the need to cut or trim shims.
