NEXT BY DANCO Perfect Seal Toilet Wax Ring
This product is innovatively designed to take the guesswork out of toilet installation. It has a black plastic ring located inside the grey rubber housing that is removable to allow the seal to compress fully on itself.
Therefore, if the flange and horn are very high above the tiled floor, you can remove this plastic so that the toilet can compress the flange and seat flush on the floor.
On the drain part, this unit features a patented seal design that makes use of specially made rubber gasket that is encapsulated with wax. This forms a seal, which is 3 times stronger than regular wax rings and does not cause any mess.
The gasket grabs the toilet while the wax is pushed down the walls of the drain pipe, ensuring that a strong seal is formed between the drain pipe wall and the flange sleeve.
Such a strong seal means that the toilet flange can maintain its integrity even with small toilet movements, which are very common as you use it.
Structurally, this unit is made from plastic but it is strong enough to stabilize toilet bolts so that the toilet can attach firmly onto the floor.
Features at a glance
- Accommodates flange heights of between 0.5 inches above the floor (due to the removable plastic) to 1.5 inches below the floor.
- Specially designed rubber gaskets that are encapsulated with wax.
- 3 times stronger seal.
- Can fit drainpipes of any size since the wax fills the gap between both the flange wall and the drainpipe wall.

Korky 6000BP Universal Toilet WaxFree Seal
The Korky 6000BP has a universal design, which means that it can fit on both 3 and 4-inch drain pipes. It also means that this unit can fit on flanges that are above, at level with or below the floor surface and this is made possible using a two-piece foam on the interior, making it very adaptable.
Construction wise, this seal is made of rubber, which gives it a couple of advantages. First, this seal eliminates the need for wax seals, which can be very messy.
In case you don’t set the toilet properly the first time, rubber seals enable you to reset, not once, but multiple times. Wax seals are usually easily ruined and will require new ones if you mess up the toilet setting process on round 1.
Wax seals are also prone to be affected by temperature changes, which means that they can freeze or melt as the temperature goes up or down. This might result in the occurrence of a sticky mess or a hardened block, effectively affecting the integrity of the seal.
However, this rubber seal is resistant to temperature changes and thus, maintains the integrity of the seal all through.

- 2-piece interior foams enable the seal to fit on flanges that are above, at level with or below the floor surface.

Best Toilet Flange Buying Guide
There are many types of toilet flanges on the market. But before buying one, you should consider the following:
Compatibility
When it comes to toilet flanges, compatibility is usually considered in terms of the drain pipe size. Drain pipes are available in different sizes, with most of them being either 3 or 4 inches in diameter.
Before buying a toilet flange, it is important to check the size of your drain pipe and then check whether the flange’s sleeve is compatible with that size.
Alternatively, you can buy the universal fitting flange, which is suitable for drain pipes of all sizes.
Type of seal
A critical part of any flange is the seal. It is available in 3 main types, which are wax, rubber or silicon seals.
Wax seals are very good at forming watertight seals they are easily affected by temperature changes, which means that they can melt and get messy when it’s too hot or stiffen when it’s too cold. Either way, these conditions affect the integrity of the seal, making it prone to leakages.
Again, when using wax, once you set the toilet above the flange, the wax sets itself such that any big movement such as removal of the toilet destroys the seal.
On the other hand, rubber is reusable, which enables you to reset the toilet countless times without worrying about it getting damaged.
However, with rubber, the seal must fit snugly over the toilet horn, toilet and drain pipe so that it forms a watertight bond. Silicon is more like rubber and thus, its properties are quite similar to those of a rubber seal.
Material
Toilet flanges are also available in different build qualities. This is primarily determined by the material used to construct the unit. These include
Plastic
Most toilet flanges are made using plastic and specifically, a type of plastic called PVC. However, there are some variations of these, with some being entirely constructed out of PVC while others have a PVC body and a metallic horn.
Another commonly used plastic is ABS. This material is more rigid than PVC and is also more resistant to heat and shock as compared to PVC.
Plastic flanges are usually very affordable and are designed for 3 and 4-inch drainpipes.
Copper
The main advantage with copper flanges is that they are highly resistant to corrosion and wear and tear, making them very durable. However, they are more expensive than plastic flanges.
Cast iron
Cast iron flanges are quite expensive but very durable. They are available in a variety of sizes, with the deep-bodied ones being ideal for drainpipes that are quite low as compared to the toilet floor. With their strong, durable sleeves, they can extend deep down to reach the drain pipe so that water is passed from the flange to the pipe without any leakage.
Aluminum
Aluminum toilet flanges are designed to be strong and durable by being corrosion resistant, yet lightweight for easy handling.
Stainless steel
Stainless steel flanges are also very durable because of their resistance to oxidation and corrosion, but they come at a high price.
Brass
Similar to stainless steel, these are very durable.
Generally, metallic toilet flanges are quite expensive than their plastic counterparts. However, they are very durable and are guaranteed to serve you for a long time.
The height of the flange
If you have renovated your bathroom floor, chances are that the floor raised a bit to leave the drain pipe sunk. It is important to consider the depth of this sunk pipe so that you can buy the appropriate flange that can extend to that level.
Similarly, if the old flange is raised above the floor, you should buy a compressible unit so that it does not leave the toilet floating and loosely attached midair.
Clearly, there is a lot about toilet flanges than their simple, rounded appearance. After going through this article, you will understand what the different features of these components mean in terms of the benefits they provide. With this information, I hope, you should be able to pick the best flange for your toilet from the 5 units reviewed above. Conclusion
