Most toilets have 2 inches trapways which is sufficient to handle the average waste produced in your home. Unfortunately, sometimes standard-sized trapways aren’t enough; hence you will need to get a toilet with the largest trapway.
A large trapway offers a wider path for wastes to pass, allowing them to drain more effortlessly into the sewer. With a large trapway, your toilet will not clog or leave some waste behind.
Some toilets with large trapways have outlets with a diameter of up to 3 inches.
In this post, I will look at the best toilets with the largest trapway to help you choose a toilet that will suit you best.

There are multiple to love the American Standard, like its amazing flushing performance and fantastic look. This toilet is a household favorite, excelling in cleaning bowls and handling bulk waste without clogging the drains.
The Champion 4 stands out for several other reasons, especially its impeccable performance. For instance, the 2-3/20 cm trapway can handle up to 75% more waste compared to a standard toilet.
Moreover, it has a 10 cm long flush valve with a piston action accelerator. This, together with the siphonic action bowl that has EverClean anti-bacterial glazing and jets, you will have a spotless bowl at all times.
It’s a one-piece toilet designed to meet the Americans with Disabilities Act (ADA) standards. For example, Champion 4’s height reaches 17-19 inches and has a longer bowl giving you more legroom, and men can comfortably use it.
Champion 4 also comes in linen and bone with a Vitreous China coating. However, this toilet isn’t great in conserving water, with a water consumption rating of 1.6 GPF.
