What to Consider When Buying the Best Toilet that Does Not Clog – Buying Guide

Perhaps, the most annoying process in your bathroom is having to plunge out clogs from your toilet. This is something you don’t want to experience, especially on a regular basis. For this reason, investing in the best toilet that doesn’t clog is a wise decision and can help you avoid these embarrassing experiences every few days. But what makes your toilet clog?

Common Causes of Toilet Clogs


If you still have the first generation toilet installed in your toilet in these ages, you must have a plunger besides. This is because these toilets cannot clean their trapway or drain efficiently. Since these low-flow toilets clog easily, you better replace them with no-clog toilets. You can get a very affordable toilet that does not clog and forget about using a plunger.

Blocked Toilet Traps

A toilet trap is U-shaped and always filled with water to keep off odors from the sewer line from seeping into the bathroom. The U-shaped bend in the trap makes clogging of the toilet easy, especially with high toilet usage or flushing of hard objects when they settle in the trap.

Flushing Non-Flushable Stuff

Flushable toilets are designed to flush human waste and soft toilet paper. However, flushing foreign objects that are harder than human waste or toilet paper, will cause clogging. For instance, things like sanitary pads, hard paper, diapers, wet wipes, and other non-flushable items easily clog your toilet.

Toilet Paper Usage

Toilet paper can also be the cause of clogs in your toilet, especially when it holds up together in the trap. You can avoid this by folding your used toilet paper instead of rolling it into a ball-like shape. Moreover, reduce toilet paper usage to a bare minimum.

How Can I Choose the Best Toilets that Don’t Clog?

Before you hit the market to shop for the best toilet that doesn’t clog, you need to know about the features to look for before buying one. Besides, understand the specifications of the toilet will ensure that you go home with a perfect toilet unit that doesn’t clog. As such, here are some of the key features that will enable you to distinguish the best toilet that doesn’t clog from the regular ones:

Flushing Mechanism

Different toilets come with different flushing mechanisms depending on the manufacture. However, the most common flushing systems that are used on modern no-clog toilets include tank-less and dual flush systems.

A dual flush system enables you to choose what amount of water to use depending on the type of waste your want to flush thus enabling you to conserve water. For the tankless system, the flushing of the waste depends on the flush pressure as water does not refill the tank.

Also, a toilet can come with a siphonic or wash-down flush system. For the siphonic flush system, the flushing process is triggered by water from the tank. Once you press the flush button, water pushes waste down to evacuate the bowl content.

When choosing a flush toilet, choose one with large valves and trapway outlets to ensure powerful flushes with no clog.

One-Piece or Two-Piece

One-piece toilets are becoming popular as they feature a sleek and seamless design that makes them fit well in any modern bathroom design. besides, they are constructed with fewer joints and seams making them easy to clean as they don’t harbor much dirt or moisture. However, they are a bit difficult to install and quite expensive.

The two-piece, on the other hand, is still available in plenty on the market. However, they come with some downsides that are not experienced in the one-piece models and these are difficult to clean due to many joints and crevices. However, they are often cheaper depending on the brand and are overly easy to install.

The choice between these two toilet types may boil down to preference as both have their good and bad sides.


Most flush toilets are made of ceramic material, which is a mixture of silica, clay, and fluxing agent. However, the difference often is in the color, shape, and type of finish that covers the toilet. The kind of material that a toilet has also dictates how easy it is to clean and maintain. The smoother the outer layer, the easier the waste moves down the toilet thus preventing clogs.

Bowl Types

Even though the kind of bowl the toilet unit features has nothing to do with clogging, choosing the right bowl type will guarantee you comfort. However, this is a matter of preference and taste. You can either choose one with a round bowl shape or an elongated one.

Elongated bowls are said to be more comfortable, but they require more space for installation owing to their protruding shape. On the other hand, round bowl models are space-saving and are a perfect choice for small-sized bathrooms. However, they can be less comfortable for some users.

Some manufacturers also design square bowl toilets, but they are not in big demand as the elongated and round bowl toilets. You can also consider having a low-profile model, especially if you have limited space in your bathroom.

Water Usage

According to studies by EPA, residential toilets consume about 30% of water across the US. With this in mind, you would want to have a toilet that will help you keep your water bills as low as possible. As such, consider choosing toilet models that are EPA WaterSense certified and consume less than 1.6gpf. Fortunately, all the toilet models in this review consume less than 1.6 gallons of water per flush.


Like most household fixtures, flush toilets can fail unexpectedly. However, you can avoid these and many other problems with your toilet if you choose one with an extended warranty period. The least warranty period offered by manufacturers is often one year, but the best no clog toilet comes with a 5-year warranty or more.

Final Thought

Without a doubt, there are plenty of the best no-clog toilets on the market. However, having read through our buying guide, you can be sure that picking the best toilet that doesn’t clog shouldn’t be a hassle.

When choosing, just make sure that the toilet you choose is water-efficient, easy to install, and clean as well has comes with a powerful flush system. All the toilets we reviewed are not only efficient with water consumption and clog-free but also stylish and comfortable for most users. So, which one would you pick?
