Toilet flanges are a necessary operating part of a toilet system. There are several kinds of toilet flange that are equally durable but have a huge price variation. One of the longest lasting types of toilet flange is the brass flange. These flanges are extremely durable but the cost of purchasing and installing them is prohibitive to most consumers. Another very durable toilet flange is the stainless steel flange. Like its brass counterpart it is also expensive to purchase and install. PVC is the most durable of the commonly used toilet flanges. Most homeowners can install it themselves and the cost to purchase isn't prohibitive.
