How To Find The Right Flushing Kohler Toilet- The Buying Guide

You just can’t pay for anything without having proper information. The case gets even more serious when you are out to buy a toilet. Don’t worry; the following key factors can help to make the right choice while buying a Kohler toilet.

  • Shape and Size

When buying the best flushing Kohler toilet, it is recommended to check the size and shape for an ideal fitting in your bathroom. There are two toilet shapes available on the market, including elongated bowls and round bowls. Round bowl toilets are fatter and shorter in size, whereas elongated bowl toilets are longer than round toilets. An elongated bowl measures between 18 inches to 19 inches. Elongated toilets offer maximum comfort than round toilets.

The toilet height can be a serious factor for most users. For instance, you can buy a heated toilet seat, but you won’t enjoy the process due to improper height. The standard toilet height is about 13 to 15 inches tall. For extra comfort, you can go for 17 to 19 inches of toilet height.

  • Flushing Toilet type

There are two types of flushing toilets available, one piece and two piece toilets. Both types of toilets have different flushing systems. The best thing about one piece toilet is that it doesn’t have complicated assembling. The toilet bowl and water rank come connected. The one piece toilet is known for its sleek design and effortless cleaning. Also, you don’t need to worry about bacterial building up.

On the other hand, two piece toilets are more conservative and ideal for regular bathrooms. The dark side is you need a good plumber for installing process. A seal connects the toilet bowl and tank. One benefit of two piece toilets is that they are cheaper than one piece toilets.

Types of Toilet Flushing Systems

  • Gravity Flush Toilets

The traditional flush system is powered by gravity, utilizing the weight of water to create a flushing pressure. Most water tanks sit directly on the bowl’s top, whereas some gravity systems have an elevated cistern to enhance the distance of water. Water from the toilet tank is forced into the bowl, cleaning it and eliminating waste at the same time.

A gravity flush system is one of the oldest mechanisms for flushing toilets. In fact, it’s the simplicity of these flushing systems which kept them around for centuries. It has only a few moving parts, and that’s why they are known as the quietest flush systems.

  • Pressure Assisted Toilets

Pressure-assisted systems are similar to gravity flushing toilets, but they have an additional mechanism used to force water into the bowl even harder. A plastic tank with an air-filled balloon is pressurized when the water begins to refill the ceramic tank of the toilet.

During flushing, the compressed air in the balloon pushes water into the toilet bowl at a higher flow rate. It helps to use less water without affecting the flushing performance of a toilet and saves water to reduce bills.

Due to an extra force applied during flushing, a pressure assisted toilet produces loud flushing noise compared to other flush types. If you are concerned about flushing sounds, pressure assisted toilets are not for you.

  • Dual Flush toilets

Dual flush systems are getting popular due to the environmentally conscious design that allows one to choose more or less water depending on flushing needs. The flushing system comes with two buttons or levers installed on the same unit. It allows selecting full flush for a large waste and partial flush for liquid or small waste.

A full flush uses 1.6 gallons of water, whereas a partial flush uses 1.1 gallons of water to remove waste from the toilet bowl.

  • Tornado/Double cyclone flush toilets

Tornado flush is new addition introduced by toilet manufacturing company Toto. Instead of the typical rim holes, the tornado flush system releases water into the toilet bowl with two large nozzles on both sides of the unit to create a centrifugal, cyclonic rinsing action. The double cyclone flush system uses 1.28 gallons of water for both solid and liquid toilet waste.

  • Water efficiency

Before making a decision, it is essential to consider whether the toilet is capable of conserving water or not. You can check the flushing water with every toilet we have reviewed. Dual flushing toilets are best as they conserve more water compared to other flushing toilets. Make sure to check how many water gallons per flush the toilet needs to remove waste from the bowl.

  • Flush Valve

Most people don’t pay attention to the flush valve when buying the best flushing toilets. Remember, the wider the valve, the more water can pass easily, and the more powerful the flush will generate.

  • Comfort

When buying a toilet, comfort should be your top priority. Height is an essential factor for comfort, especially for those with joint issues or any disability. Check the toilet seat because you will sit on the seat, not on the entire toilet.

  • Rough-in Distance

The distance between the center of the toile flange and the wall is known as rough-in. Don’t forget to take measurements to ensure the toilet fits the rough-in space in the bathroom. The baseboard thickness will add a few inches to the rough-in. Please note down the standard distance (about 12 inches), but various modes also range between 10 to 12 inches.

Final words

Kohler toilets are, without any doubt, the most demanding toilets available on the market. Durability, flushing power, and convenient installation are the prominent features that most people love about Kohler toilets. However, it doesn’t mean you should blindly choose any Kohler toilet. Your bathroom may be different from the toilet you are choosing. That’s where you need to note down your requirements before making a decision. Quality isn’t an issue but choosing the right flushing Kohler toilet is the prime factor you should focus on.
