How To Install A Toilet Flange On Top Of Tile: A Step-by-step Guide
What To Know
- Installing the flange on top of the tile can create an uneven surface, compromising the stability of the toilet and potentially causing leaks.
- This flange is made of plastic and has a wax ring that creates a seal between the flange and the toilet base.
- Measure the distance from the wall to the center of the existing drainpipe and mark the location on the floor.
When installing a toilet, one of the crucial steps is placing the toilet flange correctly. This metal ring provides a stable base for the toilet and ensures a proper seal. However, the question arises: does the toilet flange go on top of the tile or beneath it? In this comprehensive guide, we will delve into the details of toilet flange placement and provide a definitive answer.
Understanding Toilet Flange Placement
The placement of the toilet flange depends on the type of flooring used in the bathroom. Typically, there are two main scenarios:
1. Tile Flooring
Does the toilet flange go on top of tile?
Answer: No, the toilet flange should not be installed on top of tile.
When installing a toilet on tiled flooring, the flange should be placed beneath the tiles. This ensures that the flange is secured to the subfloor, providing a solid foundation for the toilet. Installing the flange on top of the tile can create an uneven surface, compromising the stability of the toilet and potentially causing leaks.
2. Non-Tile Flooring
Does the toilet flange go on top of non-tile flooring?
Answer: Yes, the toilet flange can be installed on top of non-tile flooring.
In the case of flooring materials such as vinyl or linoleum, the toilet flange can be placed on top of the flooring. However, it is important to secure the flange to the subfloor using screws or bolts to prevent movement and ensure stability.
Installation Steps for Toilet Flange
1. Determine the Flange Type
There are two main types of toilet flanges:
- Wax ring flange: This flange is made of plastic and has a wax ring that creates a seal between the flange and the toilet base.
- Screwed flange: This flange is made of metal and is secured to the subfloor using screws.
2. Mark the Flange Location
Measure the distance from the wall to the center of the existing drainpipe and mark the location on the floor.
3. Cut the Tile (for Tile Flooring)
If installing on tile flooring, use a tile saw to cut a hole for the flange. The hole should be slightly larger than the outer diameter of the flange.
4. Place the Flange
Insert the toilet flange into the hole and ensure it is flush with the subfloor (for non-tile flooring) or beneath the tile (for tile flooring).
5. Secure the Flange
For tile flooring, use thinset mortar to secure the flange to the subfloor. For non-tile flooring, use screws or bolts to fasten the flange to the subfloor.
6. Install the Toilet
Once the flange is secured, install the toilet according to the manufacturer’s instructions.
Common Mistakes to Avoid
- Installing the flange on top of tile: This can compromise the stability of the toilet and lead to leaks.
- Using the wrong flange type: Wax ring flanges are suitable for tile flooring, while screwed flanges are better for non-tile flooring.
- Not securing the flange properly: A loose flange can cause the toilet to wobble or leak.
- Installing the toilet before the flange is secured: This can damage the flange and create an uneven surface.
Troubleshooting Tips
- Toilet is loose: Check if the flange is securely fastened to the subfloor. Tighten the screws or bolts if necessary.
- Water leaks around the toilet base: Inspect the wax ring or gasket for damage or improper installation. Replace if needed.
- Toilet flange is too high: If the flange is too high, the toilet may not sit level. Use a flange extender to raise the flange to the correct height.
- Toilet flange is too low: If the flange is too low, the toilet may not be able to create a proper seal. Use a flange spacer to lower the flange to the correct height.
Other Considerations
- Floor height: When replacing a toilet, ensure that the new toilet is compatible with the existing floor height.
- Toilet weight: Consider the weight of the toilet when choosing a flange. A heavy toilet may require a reinforced flange.
- Subfloor condition: Inspect the subfloor for any damage or rot before installing the toilet flange.
Wrapping Up
To achieve a secure and leak-free toilet installation, it is crucial to understand the correct placement of the toilet flange. On tile flooring, the flange should be installed beneath the tiles, while on non-tile flooring, it can be placed on top of the flooring. By following the steps and tips outlined in this guide, you can ensure a successful toilet installation that will last for years to come.
Basics You Wanted To Know
1. Can I install a toilet flange myself?
Yes, you can install a toilet flange yourself if you have basic plumbing skills. However, if you are not confident in your abilities, it is recommended to hire a professional plumber.
2. How often should I replace my toilet flange?
Toilet flanges typically have a lifespan of 20-30 years. However, it is recommended to inspect the flange regularly for any signs of damage or leaks.
3. What type of toilet flange is best for my bathroom?
The best type of toilet flange depends on the type of flooring in your bathroom. Wax ring flanges are suitable for tile flooring, while screwed flanges are better for non-tile flooring.
