What to Consider Before Buy

In order to ensure you spend wisely, there are certain key factors you want to consider in order to determine if a particular toilet is right for you. Let’s quickly look at each one of them.

Water Consumption

Water consumption is critical when choosing a toilet unit. This is because a huge percentage of the water in your home is used for flushing.

A typical flush basically requires up to 1.6 gallons of water. Thus choosing an inefficient unit can greatly increase your water bills.

Shape and Size

Another important consideration you need to make when purchasing a Kohler toilet is the shape and size of the unit. And this also applies to any other brand.

This is because both shape and size play a huge role in determining the level of comfort the toilet provides as well as the amount of space it will take up in your bathroom.

Most Kohler toilets usually have an elongated shape or a compact one which may be round or square. The elongated seat toilets tend to occupy more floor space than the compact ones. Most of the time, this is usually around 2-inches.

As a result, the compact round face toilets may be referred when there’s need to save space as in the case of a small bathroom. However, in terms of comfort, elongated seats tend to do better.


Another thing you may likely consider when purchasing a toilet is the style.

There are basically two styles available – the one-piece and two-piece style. This doesn’t only apply to Kohler toilets but other brands as well.

The two-piece toilets tend to be more popular and usually consist of separate tanks and bowls which are connected together, while the one-piece exists more like a single unit. The latter is usually less expensive but may not be as sleek as the one-piece design.

Since there is no seam or space between the bowl and tank in a one-piece toilet, there is little room for bacteria. This makes them generally toilet easier to clean.

Tank Size and Valve

Another thing that might likely come up when purchasing a toilet is the tank capacity. Although this is not something you need to be overly concerned about but it’s still a good idea to have it in mind.

You want to consider the size of the tank flush valve since it’s responsible for releasing the water from the tank whenever you flush the system. A larger flush valve is desirable as it results to higher water flow rate which makes flush more powerful and efficient.

This way, there’s little chances of residue since the water will be flowing with a greater force. Luckily, all the items we’ve reviewed above meet this criterion, so you have absolutely nothing to worry about.

Flush System

A critical consideration to be made when shopping for any type of toilet, whether it’s Kohler or any other brand, is the flushing system.

There are two major flush design – the gravity flush and the pressure assisted flush toilet. Kohler toilets basically use any one of these systems.

As its name indicates, a gravity flushing toilet relies on the weight of water for its flushing action. It accomplishes this through water siphoning. This method is simpler and older than the use of pressurized air. They are also quieter and less expensive but less powerful.

On the other hand, the pressure assisted system uses pressurized air to force water into the toilet bowl anytime you engage the flush lever. This ensures a powerful flush and leaves little-to-no chance for clogging to occur.

However, toilets that are based on this system are usually noisy and tend to be more expensive than the gravity flushing systems.

Are Kohler Toilets Reliable?

Choosing the correct toilet for your convenience is not an easy task. Everybody searches for a toilet that will be durable and provide longtime service. So far, we have talked about different types of Kohler products, which brings us to this critical question of whether it is a reliable brand.

When it comes to choosing such an essential and vital necessity like a toilet, it is always better to go for a brand that knows what they are doing. Not only do their toilets come with superior quality, but they also ensure an extensive level of durability.

Furthermore, they push the limits of technology by introducing new and innovative designs frequently.

Moreover, when it comes to sustainable sourcing of materials, you will not find a better toilet company. They produce energy-efficient and environment-friendly products that contribute to securing our nature from its current water crisis. Hence, we can assure you that Kohler toilets are reliable.

Is Kohler a Good Toilet Brand?

Kohler is a good brand and the absolute best choice if you search for the most iconic bathroom and toilet fixtures. No other toilet brand will provide you the same level of durability and quality as the Kohler one. Here are the reasons that will change your mind as well.

Quality Check

Maintaining the same level of superior quality products all year long is a commitment. Not all brands can keep up with such tasks, and some even go under because they cannot keep up with the demand and quality.

All your misconception about expectation vs. reality will change because Kohler constantly improves and develops newer technologies to keep up with people’s demands.

International Success

It is always such a bummer when you instantly like a product but cannot purchase it because the brand did not receive much international recognition and does not ship to your country. Kohler is not only famous in the US but also overseas.

Social Responsibility

People are aware of the damage that the low-quality product causes to the environment now more than ever. Hence, Kohler creates not only energy-efficient products but also uses eco-friendly materials.

What Toilets Are Better, Kohler or Toto?

The two most popular companies when it comes to durable, quality, and efficient toilet products are Kohler and Toto. It is natural to find yourself in a dilemma when choosing between these two. Hence, we will provide our expert opinion on which company is the better one.


When it comes to toilet fixtures, durability and longevity matter the most—both Kohler and Toto manufacture excellent products with superior materials. Vitreous China material is the core component they use in most of their products.

Waste and particles do not stick on this material much; hence, both brands employ this material.

Flushing Performance

Since both the Kohler and Toto companies use the same type of material, let us look into their toilet’s flushing performance. The Toto toilets contain both the G-max flushing mechanism and the Cyclone flushing system. Additionally, they also have an E-max flushing system that comes with eco-friendly properties.

On the other hand, Kohler toilets have an AquaPiston flushing mechanism, which is efficient but not as excellent as the Toto brand’s G-max system. Another problem with the AquaPiston is that it creates louder noise.


Since Toto brand’s superior G-max flushing system helps remove debris from the bowl correctly, you will not worry about cleaning the bowl so frequently. Kohler, on the other hand, may require frequent cleaning.

Overall, it is safe to say while the Kohler toilets contain superior quality in certain aspects, the Toto ones are far better.

Installation Tips

After purchasing a Kohler toilet, the next thing you will need to do is install the unit. As earlier indicated, these toilets are easy to install and anyone can do it.

Although Kohler toilets generally have a similar installation process, we still advice you to follow the instructions that are laid out in the installation manual that comes with the particular model you purchase.

It is important to note that even though these toilets all come from the same manufacturer, they do not all have the same design. So you can expect their set-up to differ.

Below are some useful tips to help you achieve authentic successful installation.

  • First and foremost, be sure to follow the safety tips that come with the product you purchased. This is extremely important and we cannot emphasis it enough.
  • Observe all local plumbing and building codes.
  • Get all the tools you will need in one place. Depending on the unit you want to install, you will likely require a putty knife, adjustable wrench, hacksaw, sponge, level, replacement wax seal and a tape measure.
  • Before you begin installing the new toilet, turnoff and disconnect your water supply. Get rid of any water that might be remaining in the tank and bowl before removing the old unit.
  • Avoid removing the unit with force. Instead rock from side to side to loosen the seal after removing the bolts that secure it.
  • Use a putty knife to remove the old wax seal and wipe away any remaining wax with a sponge or rag. Then place the new wax seal and secure the new bowl to the floor.
  • To avoid leakage, don’t move the toilet after the wax seal has touched the flanch.
  • Be careful not to tighten the nuts to avoid damaging the product.
  • After setting up the bowl, reconnect the water supply.
  • Before connecting the water supply to the tank again, make sure you check for leaks. If you spot any leaks from the valve, then make the needed adjustments before reconnecting the source to the tank.
  • Make sure you install the best quality toilet seat according to the manufacturer instructions to avoid having issues later.

Finally, if you don’t feel confident enough to undertake the installation on your own, then consult a professional plumber to help you out.
