Tiling Under Toilet Flange For Ceramic Vs Vinyl Tiles

When it comes to bathroom renovations, an important decision needs to be made: should the toilet flange go on top of or under the tile? This choice is crucial for ensuring a proper and durable installation. The type of tiles used in the bathroom plays a significant role in determining the best approach.

  • If you opt for ceramic tiles, it is recommended to tile under the toilet. Ceramic tiles are thick and sturdy, able to withstand the weight of the toilet without any issues. Tiling under the flange provides a solid foundation, ensuring stability and preventing any movement or damage to the tiles. It also creates a seamless look, as the flange blends in with the surrounding tiles.

  • On the other hand, vinyl tiles are thinner and more flexible than ceramic tiles. They have their own considerations when it comes to installing the toilet flange. Vinyl tiles can peel off or crack under the weight of the toilet if the flange is placed directly on top of them. Therefore, it is advisable to avoid placing the flange on top of vinyl tiles, as it may compromise the integrity of the flooring.

  • To summarize:

  • For ceramic tiles: tile under the toilet for a solid foundation and seamless look.
  • For vinyl tiles: avoid placing the flange on top to prevent damage to the tiles.

Recommended Screws Length For Securing Flange To Tiles

When securing the toilet flange to the tiles, it is crucial to choose the appropriate screw length. Plumbers typically use screws that are approximately two inches long or twice the thickness of the tiles.

The reason for this specific screw length is to ensure a strong and secure connection between the flange, tiles, and subfloor. Using screws that are too short may result in a weak attachment that can loosen over time, causing leaks or damage to the flooring. Conversely, using screws that are too long can penetrate through the tiles or crack the subfloor, compromising the stability of the toilet.

Before proceeding with the installation, it is essential to measure the thickness of the tiles accurately. This will help you determine the appropriate length of screws needed to secure the flange to the tiles effectively.

Here are a few key points to remember:

  • Choose screws that are approximately two inches long or twice the thickness of the tiles.
  • Using screws that are too short can result in a weak attachment and potential damage.
  • Using screws that are too long can penetrate through the tiles or crack the subfloor, compromising stability.

Always measure the thickness of the tiles accurately before securing the flange.

Remedying Flange Installation Without Tiles

In some cases, the toilet flange may be installed directly to the floor without any tiles. This can occur during previous renovations or if the bathroom has an alternative flooring material, such as linoleum or hardwood. However, if the flange lacks the support of tiles, it may lead to issues such as leaks or an unstable toilet.
