Top 10 Best Toilet Flange Extender Reviews

There is nothing that makes living in a home uncomfortable more than a bathroom with a leaking toilet. In addition to the fact that the bathroom floor will always be wet, a poorly fitted toilet flange also creates an unnecessary hygiene risk in the home. A quick and effective way to repair such a problem is adding a flange extender to an existing toilet setup. Here, is what you need to know about toilet flange extensions, and how to pick the best for your bathroom.

Qualities to look for in the best toilet flange extender

With the countless flange extender brands in the market, it can be hard to pick the right one. However, there are a few guidelines that can help you choose those that are best suited for your situation:

The height of the flange

The flange extender is supposed to form a connection between the upper part of the toilet and the drainage system below. The flange extender should therefore rise a few inches above whatever flooring material you have used for the bathroom.

The changes to the floor

The changes that have affected your floor are what determine the perfect flange type to use. For instance, if you had a concrete floor in the bathroom and replace it with tiles, the height of the flange will have to be brought up to compensate for the increase caused by the tiles.

The material of the extender

The ideal material to make a flange extender is a durable plastic. These plastics are ideal because they can fit over existing PVC, stainless steel, cast iron and ABS flanges.

Additional features

Certain additional features improve the durability and efficiency of an extender. For instance, an extender that has a stainless steel ring will last longer than the basic plastic and will be less prone to damages.

The water tight seal

The extender will only be useful when a water tight seal is formed between the upper and lower parts of the toilet drainage system. For this to happen, the flange extender should have a rubber gasket. If you purchase a model without a rubber gasket, you will have to seal the setup with caulk when you are finished with the process.

Durability

The toilet is a moist environment. Additionally, the flange extender will be in constant contact with toilet waste which makes it more vulnerable to damages. It is, therefore, important to get superior quality flange material for the perfect watertight fit around the toilet.
