FAQ

How do you anchor a toilet flange to concrete?

To securely attach the toilet flange to a concrete slab, you can utilize Tapcon anchors or a comparable type of masonry/concrete screw. It’s important to exercise caution when using plastic flange rings to avoid cracking them by over-tightening the anchors. This method of fastening provides a reliable and durable connection between the flange and the concrete slab, ensuring the stability of the toilet installation.

Does toilet flange sit on concrete or tile?

When renovating your bathroom floor, it’s important to remove the toilet in order to properly install tiles underneath it. This ensures a seamless and professional finish.

Therefore, it is important to follow the best practice of placing the toilet flange on top of the finished floor for optimal performance and prevention of leaks.

Can a toilet be installed on a concrete slab?

One common method for installing plumbing is to cut through the concrete slab in order to lay the pipes and connect them to the existing sewer connection.
