Things To Consider When Buying No Clog Toilets

Best non-clogging toilets review

Toilets come in many designs and different shapes. The operating mechanisms also vary depending on the components.

To avoid a bad shopping experience, here are a few factors you need to keep an eye on: 

Flushing System

Since your search is about the best no-clog toilets, then flushing ability has to be at the top of the list. The best technologies out there include TOTO’s GMAX, tornado, and Double Cyclone flushing systems.

If you have a big family where the toilet gets busy all through, there is a possibility even the best no-clog models can fail.

In such cases, going for a pressure-assist toilet would be advisable. Consider this a warning-they flush loudly. 

Water Consumption

Most toilets currently consume between 0.6 to 1.6 gallons per flush. Avoid any toilet that goes beyond that range.

To be on the safe side, go with choices that are approved by regulatory authorities such as WaterSense, and EPA.


Toilet bowls mostly come in either round or elongated designs. While both have their advantages and disadvantages, the latter is a common installation in many homes.

Toilet type

There are many toilet types but two are common; two-piece and one-piece.

In the latter, both the bowl and flushing tank are united into a single unit. In the case of the former, the tank and bowl are apart.

One-piece toilets are space-saving and a little lighter as well. However, such a convenient design elevates their price just a bit.

Final Thoughts

There certainly are many best no-clog toilets on the market. Their sheer number can make buyers confused with what to go for.

Some of the models we have reviewed come highly recommended. You can check them out if you don’t have anywhere else to look or don’t want to risk going for unknown models.

With toilets, you tend to get what you pay for. So if you want exceptional performance, you’ll have to dig a little deeper into your pockets.

All in all, happy hunting!
