Have you ever had a situation where water from the drain was getting back into your sink? Or maybe odors escaping into your house through the sink? I can’t even begin to tell you how frustrating that can be.
But tell you what? With the best p trap, you can solve the issue entirely.
A good p trap that is installed properly creates an excellent seal and prevents water and smells from flowing into the sink.
There are many choices on the market – plastic, metal, rubber, flexible, stiff, and so on.
In this article, I will help you identify the type that works for you as well as the correct size. Moreover, I will introduce to you some great options you can select.
Let’s get started.
Things to Consider Before Buying P Trap for Sinks and Bathroom
It can be a little tricky to know the p trap for your plumbing system, especially if you’re doing the installation/reinstallation for the first time. But tell you what? Knowing the correct unit is as simple as considering the following factors.
The first thing you need to think about is the material. Usually, there are three choices – plastic, rubber, and metal.
Metal is the most durable of the three, but it is also inflexible and harder to install than the rest.
To pick the right material, check the existing plumbing fixtures on the drain pipe. Be sure to use the same material that is in the fixtures. For instance, if plastic fixtures are used, use a plastic p trap.
When it comes to looks, metal p traps are the way to go, especially the chrome-plated brass types. These have a nice chrome sheen that makes the whole installation looks nice and classy.
If you’re doing the installation in a tight space, you’re better off with a flexible p trap pipe, ideally made of rubber or a plastic-like polypropylene. Such a unit can bend and fit tight spots more comfortably.
Flexibility is also good in the sense that it works better to prevent leaks. When the pressure increases, the pipe will expand instead of breaking or bursting.
Another advantage of flexible p traps is that they are extendable. You can extend or draw back the trap to suit the available space.
P traps come in two popular sizes – 1-1/4 and 1-1/2 inches. The 1/1-4 is commonly used for bathroom sinks while the 1-1/2 is often used for kitchen sinks. Please keep that size difference in mind before you make your purchase.
Again, be sure to check the length of the trap. For instance, if the distance between your sink and drain is large, then you need a long trap that can connect to both ends. Again, if it’s a short distance, there is no need of getting an overly long p trap that leaves a slack.
Where Can P Traps Be Used?
A good number of p traps can only be used with bathroom sinks. Such units cannot be used in the kitchen because if solid items like food remains are put through them, the p traps end up getting blocked.
If you want a p trap that you can use with disposal, go for a strong, solid unit with a smooth interior. A smooth interior helps the solids move without getting stuck.
Our Top 7 List of The Best P Trap in 2022
1. Expandable & Flexible EasyDrain p trap
If you’re looking for the right p trap for problem sinks, the EasyDrain Ref. 510 Expandable & Flexible 1-1/2″ may be exactly what you need. This unit is easy to use and it works seamlessly.
One of the reasons why people love this is the flexibility. The trap is more flexible than anything you can find at Lowes, which makes it effective and easy to install. Both ends of the pipe can be identical, meaning either end can function as a tailpiece.
In its closed position, the trap has a length of 10.25 inches. When extended, it goes up to 28 inches long.
Assuming the drain from the wall is too high for the sink, the standard trap may not help. In such a scenario, you may need to rework the plumbing, a quite tiresome and time-consuming process.
However, because of its big extended length, the Easydrain trap can be very useful. With it, you don’t need to rework the plumbing at all. Therefore, you save time and energy.
Do you have a sink with a tight angle or a bad corner that makes it hard to install a p trap? The Easydrain’s flexible body makes it easy to install in such places. It will bend without much effort, and even if the sink and drain don’t line up well, the trap will work.
Before you purchase this item, realize that it is not meant for drains that take solid wastes like food. This is only for sinks meant for hand-washing, meaning it is ideal for bathroom sinks.

Frequently Asked Questions
1. What is an ideal material for P-trap?
There are three common materials for p traps – metal, plastic, and rubber. Rubber and plastic are loved for their flexibility, which makes them the easiest material to install.
Plastic is generally cheaper than the rest, while metal offers unmatched durability and beauty.
2. What is the correct p-trap size to get?
There are two sizes to think about – the diameter and the length. Look for a size that matches your sink and drain, and the distance between the drain and the sink.
If you’re installing it under a bathroom sink, the right size is likely 1/1/4, and if it is a kitchen sink, the correct size is probably 1-1/2.
3. How do p traps work?
A p trap gets its name from the p shape that is formed at the lower end between the vertical pipe from the sink and the pipe entering the drainage. The purpose of the p shape is to keep the fluid from flowing back into the sink.
Moreover, it keeps the foul gases from the sewer from getting into the house through the sink.
4. Which one is better plastic and metal p-traps?
Metal p traps are superior to plastic ones because they resist heat a lot more effectively. Because of their heat-resisting capability, metal p traps are better for kitchen installations.
The hot water will not cause damage to the trap. Another reason why metal traps are better is that they look more presentable.
5. Is a p trap better than an s trap?
The whole idea of traps is to create a water seal. When it comes to that, p traps are considered more effective. If you’re wondering which one to install, go for p traps.
Before you purchase a p trap, think about the material, size, function, and the other factors we discussed above. Metals like zinc alloy with chrome plating work great because they resist heat and last ages.
Plastic and rubber, on the other hand, are more affordable. If you’re working in a limited space, a rubber unit might be the best p trap to get because of the flexibility it offers.
Importantly, be sure to get a size that matches your sink drain.
Over to you now. The items in the reviews above were selected carefully, and they provide useful benefits like ease of installation and effectiveness in sealing the water.
