Kohler Santa Rosa Toilet Review

Interior of clean modern bathroom

With its solid market reputation and unrivaled ergonomics, Kohler is one of the leading toilet manufacturers. If you are looking for a highly efficient toilet with a durable frame, then the Santa Rosa Toilet range from the brand will be your best bet.

In this section, we’ll discuss all the reasons you should consider buying this product. Let’s get started!

  1. Advanced Flushing System

Kohler Santa Rosa Toilets uses AquaPiston Technology that releases water from the canister in a powerful stream with each push of the button. As a result, water flows downwards at a swift pace and cleans the entire bowl in one go.

Replacing the outdated flapper design that leads to clogs, we have the 360-degree valve that allows the water to shoot out from all directions. This will clean the bowl completely, leaving no residue behind.

With this toilet, you can put your plunger aside, as the chances of clogging or leakage are minimized.

  1. Ergonomically Designed

While looking for new toilets, people often forget to take ergonomics into account, prioritizing low water consumption and a powerful flushing system instead. Although these features are essential, the ergonomics of the product also adds tremendous value to it.

Unlike traditional toilets with a height of 15 inches, Kohler goes not one but two steps further and has a 17-inch height. It is therefore ideal for taller people who are tired of uncomfortably bending their knees or people with back problems.

In addition, the elongated bowl is comfortable while being compact and can fit into small bathroom spaces with ease. Besides, all toilets from this range are ADA-compliant and can be installed in homes, offices, and public places for people with mobility issues.

  1. One-Piece Toilet

Single-piece toilets are sleek and simplistic, adding a very contemporary look to the bathroom. Besides, they are pretty easy to install, even for an amateur. In addition, there are no hidden nooks or crevices where dust might accumulate, and a simple wipe down will keep it clean.

Also, since it’s a one-piece system, the tank and bowl are fused, minimizing the chances of any seal leak or breakage. This adds to the durability of the unit and saves you from frequent repairs in the future.

  1. Water-Conservation Technology

If mounting electricity bills are a concern in your household, then the Kohler Santa Rosa range will prove to be a massive boon. Traditional toilets consume a lot of water, with some models guzzling 4 gallons per flush. However, Kohler focuses on designing sustainable toilet models that aim at water conservation.

The Santa Rosa belongs to a group of high-efficiency toilets and consumes merely 1.6 gallons of water per flush. However, this doesn’t mean that the bowl won’t be adequately cleaned. The advanced flushing technology ensures that all the debris is thoroughly removed while keeping the water consumption minimal.

Lastly, we’d like to point out that this toilet is EPA WaterSense certified, making you eligible for tax rebates on water bills. Although the gallons of water used per year depend from user to user, on average, the toilet saves over 16 gallons of water annually.

  1. Sturdy Construction

Another prominent aspect of this toilet is its durable construction. Made of vitreous china, it can withstand regular wear and tear and is not susceptible to cracks or stains. It comes with proper mounting holes that firmly ground the unit to prevent wobbling.

Moreover, the neat, well-rounded corners enhance the overall appearance of the toilet. And the flushing lever on the side with a chrome finish seamlessly blends with other bathroom fixtures.

  1. Additional Features

Certain additional features add to the overall efficiency of the model. Let’s see what they are.

    • Large Surface Area

A large surface area is desirable as it doesn’t let waste stick to the bowl. In addition, the water level remains sufficiently high, thus preventing odors from lingering around the bowl.

    • Glazed Trapway

The toilet features a glazed trapway with a diameter of 2 ⅛-inches. As a result, water flow is efficiently streamlined and exerts sufficient pressure for the waste to go down with ease.

Moreover, since the surface is glazed, there is a remarkable reduction in friction, and water can pass through smoothly and in full force without getting absorbed into the ceramic surface.

    • Quiet-Close Feature

Some models in this range have a quiet-close feature that allows you to shut the toilet seat without disturbing anyone in the house.

    • Color Options

If you are bored of the standard white color, then we’ve good news for you. Kohler Santa Rosa comes with different and attractive color options - from stylish black to subtle beige options.

What Could’ve Been Better?

Now that we have spoken at length about the functionality and efficiency of Kohler Santa Rosa, it’s time to highlight some of its drawbacks. To begin with, the interconnected tank and bowl make the product heavier in comparison to two-piece sets. Besides, you’ll have to replace the entire toilet set in case of damage to the parts.

Moreover, even though the flushing system is quite powerful, you might need to flush the toilet more than once to completely eliminate solid waste and tissue paper. This usually happens when the tank is not filled to its full capacity. So, allow the tank to fill to the brim before flushing.

We’d also like to point out that the range doesn’t produce low-noise toilets. Although the flush is quieter compared to traditional toilet models, it is not soundless by any means.

Lastly, even though the 17-inch height is quite an advantage for taller people, it might be difficult for children to hop over the toilet seat.


  • Ergonomically designed, ADA-compliant toilet
  • EPA certified, water-saving technology
  • One-piece set facilitates easy installation
  • Different color options
  • Sturdy, vitreous china construction prevents cracking


  • Toilet set needs to be replaced if one part is damaged
  • Seating height is inconvenient for people with short stature
