When you gotta go, you gotta go! But you can at least make sure that the toilet is clean and comfortable.

That said, we often fail to put enough thought before buying bathroom fixtures. And when it comes to something as indispensable as a toilet, such a hasty decision can really cost you. Therefore, you must explore multiple options before finding the ideal one.

However, if you don’t have that kind of time, use this guide to choose from the top performers right now. Obviously, there are several brands and products available, but we have decided to focus on Kohler, one of the top players in the industry. It has a wide range of products, but we’ve handpicked only the 7 best Kohler toilets.

So, without further ado, let’s begin.

Best Kohler Toilets Reviewed

From one-piece to two-piece toilets, from elongated to round bowls, here’s the list of the 7 best Kohler toilets that will suit any bathroom style and budget.

  1. 3810-0 Santa Rosa Elongated 1.28 Gpf Toilet – Best Overall

The 3810-0 Santa Rosa is an excellent option for users looking for a high-quality one-piece toilet. Therefore, if you’re looking to fit a new and upgraded model that seamlessly combines comfort and functionality, this one will not disappoint. Besides, it has a range of user-friendly features, making for a reliable unit in the mid-price range.

First things first, the Santa Rosa model is a cinch to clean and maintain, which is a major relief for homeowners. After all, you’d want the toilet to stay in pristine condition for the longest time. Furthermore, it features a compact, elongated bowl, offering more support and comfort to users.

The best part about it is the perfect sitting height, accommodating most adults, thereby making it easier to sit and stand after use. Therefore, if you want a more inclusive model for home purposes, we suggest buying this right away.

Other than that, it includes a brevia quiet close seat, eliminating the unpleasant dropping sound. Meanwhile, the AquaPiston canister enables powerful and effective flushing, so you can clear the bowl in one application.

Lastly, it’s a water-saving unit, supplying 1.28 gallons per flush, which meets the standard EPA criteria.

We do not have any complaints about its performance or design, as it does well in both departments. However, we couldn’t help but notice how noisy the flush is, which might be problematic for some users. Since it uses a gravity flush system, the toilet makes a gurgling sound after application.

Type: One-Piece Toilet | Shape: Elongated | Flushing System: Gravity Flush | Water Consumption: 1.28 GPF | Material: Vitreous China | Bowl Height: Comfort Height | Bowl Shape: Elongated | Seat Included: Yes
  1. K-3999-0 Highline Two-piece Elongated 1.28 Gpf Toilet – Best Two-Piece Option

Next up, we have the K-3999-0 Highline Two-piece Elongated toilet, designed for heavy-duty and long-term use. While its sleek appearance is the first thing most buyers notice, what actually puts it ahead of competitors is its performance. Therefore, if you’re looking for a dedicated unit for home or office use, check this out.

First of all, we’re very impressed with the simplicity and ease of use this two-piece model provides. Featuring an elongated toilet bowl, the K-3999-0 is the ideal option for users looking to save space without compromising comfort.

As far as the seat height goes, it’s comparable to that of a standard chair. Therefore, it makes sitting and standing up way easier, which is a significant advantage for people with knee or back problems. Honestly, this bit alone puts it ahead of competitors since many users complain about their toilets being too low and uncomfortable.

Apart from that, it uses about 20% less water than 1.6-gallon units while also ensuring powerful bulk waste flushing with each application. Lastly, it’s a cinch to set up, thanks to the 3 pre-installed tank bolts, saving time and effort.

Well, there’s hardly anything not to like about this model as it more or fewer works as described. However, the package does not include a toilet seat and a wax ring, meaning you’ll have to buy these parts separately. Given the price, we would have liked it better if it was all-inclusive.

Type: Two-Piece Toilet | Shape: Elongated | Flushing System: Pressure-Assisted Flush | Water Consumption: 1.28 GPF | Material: Vitreous China | Bowl Height: Chair Height | Bowl Shape: Elongated | Seat Included: No
  1. KOHLER K-3619-RA Cimarron Elongated 1.28 gpf Toilet – Best Water Efficiency

It won’t be an exaggeration to describe the K-3619-RA Cimarron as ‘sleek and sophisticated’. That said, this model is the ultimate choice for anyone looking to keep things simple and low maintenance in the washroom. So, if you too are thinking along the same lines, add this to your shopping cart now. 

To begin with, this is one of the most water-efficient models on the market, saving up to 16,500 gallons a year. And this is not a mere manufacturer claim since it’s WaterSense labeled, which is granted only when the product meets EPA criteria.

Furthermore, with this, you’re unlikely to experience any back or knee pain as the sitting height is almost as high as that of a chair. However, what seals the deal for us is the innovative AquaPiston technology, which delivers quick, forceful, and clog-free flushing.

Long story short, it might use less water, but you can depend on it to efficiently clear away waste in a single flush. That aside, we also like the Drylock installation system that prevents leaking while assembling the two-piece. All in all, it’s a reliable model that brings more comfort to your daily life.

We could hardly find any faults with this high-performance unit, but the one thing that bothered us is its size. Basically, the Cimarron is not the best option for smaller washrooms or stalls as it takes up substantial floor space. While it also indicates more room for users, the model is not suitable for compact areas.

Type: Two-Piece Toilet | Shape: Elongated | Flushing System: AquaPiston Flush | Water Consumption: 1.28 GPF | Material: Vitreous China | Bowl Height: Chair Height | Bowl Shape: Elongated | Seat Included: No
  1. K-5401-PA-0 Veil Skirted One-Piece Intelligent Toilet

We’re halfway through our recommendations, and now is a good time to introduce the K-5401-PA-0 Veil-Skirted One-Piece Intelligent Toilet. If the home unit is giving you a hard time, we suggest replacing that can with this premium-quality model, designed for luxury and comfort. It may not be the most affordable option, but it sure has some incredible features for the price.

The K-5401-PA-0 Veil is a top-tier smart toilet that streamlines your experience from the get-go. For starters, it’s a remote-controlled unit with a full suite of features that brings convenience to your fingertips.

That said, it includes a stainless steel wand with adjustable water pressure, spray settings, temperature, and patterns. It also has a self-cleaning function that relies on electrolyzed water and UV light to clean the wand surface. Apart from that, it provides a front and rear wash mode for cleansing with warm water.

But that’s not all; it comes with a warm air drying system, so you can use the toilet comfortably even in winter. However, what took us by surprise is the motion-activated toilet seat and lid operation. Therefore, it can sense your presence, and you don’t need to lift the cover or seat manually.

Lastly, it features a built-in deodorization system, which keeps your toilet fresh and odor-free for next use.

We’re not the ones to nitpick when dealing with something this advanced and cutting-edge. However, it’s a pain to install this one, and your local plumber may not know their way around it. So, it’s best to keep that in mind before buying this, as you’d want to hire someone familiar with installing such high-end systems.

Type: One-Piece Toilet | Shape: Elongated | Flushing System: Dual Flush | Water Consumption: 0.8 GPF/1.28 GPF | Material: Ceramic | Bowl Height: Comfort Height | Bowl Shape: Elongated | Seat Included: Yes
  1. K-4007-0 San Souci Toilet

If you think we have run out of one-piece models, then let’s just say we’ll be discussing the K-4007-0 San Souci Toilet next. This is another water-wise unit, designed to deliver consistently for years. Therefore, if you’re looking to invest in a good-quality model that can handle regular and intensive use, this one will work just fine.

First and foremost, we’re very impressed with the streamlined one-piece design, integrating the bowl and the tank in one compact system. Therefore, if you have limited space in your bathroom and want a space-saving model, this is undoubtedly one of the best options.

Other than that, it’s easier to clean and maintain, which is frankly a life-saver for busy homeowners. However, despite its unassuming appearance, it has a powerful AquaPiston flushing system that eliminates waste without a glitch.

Furthermore, the 360° flushing mechanism ensures powerful and maximum cleaning while minimizing water usage. But if that’s not enough to convince you, let’s just say that San Souci carries the WaterSense label, which goes on to prove its efficiency.

Feature-wise, we really like the quiet-close seat and lid, enabling noise-free use throughout. Lastly, the overhanging lid is an excellent design element, which conceals the seat’s ring to enhance overall aesthetics.

Well, there’s no sugarcoating this, but the toilet seat is just 16.5″ high, which is insufficient for most users. Therefore, this can be especially uncomfortable for taller users or people with back or knee problems. So, you might want to think about that before getting this model.

Type: One-Piece Toilet | Shape: Round | Flushing System: AquaPiston Flush | Water Consumption: 1.28 GPF | Material: Vitreous China | Bowl Height: Comfort Height | Bowl Shape: Round | Seat Included: Yes
  1. K-3950-0 Tresham Two-Piece Elongated 1.28 GPF Toilet

The K-3950-0 Tresham Two-Piece Elongated Toilet deserves all attention for its stylish design and unparalleled performance. The superior craftsmanship and minimalistic appearance make it the perfect addition for small to medium-sized bathrooms. Therefore, if you’re looking to invest in a highly functional model with a smaller footprint, we recommend buying this one.

At first, we were not sure about including the Tresham model in our list. But once we tested all its different features, there was no going back. For starters, it effortlessly combines comfort and aesthetics in one neat package.

Usually, two-piece models have a very conventional appearance, often unsuitable for modern-day bathrooms. However, this unit is unlike any of those dated models, and as such, it has some incredibly sophisticated features that are exclusively found in top-tier products.

As far as the flushing system goes, its performance meets EPA criteria, thereby ensuring maximum water saving throughout its service life. To explain further, the large canister flush valve supplies water to the bowl, creating a powerful vortex action to clear all waste. Meanwhile, it also conserves water to reduce wasteful flushing.

Apart from that, we really appreciate the comfortable seating height, allowing users to sit down and get up with ease.

For something with such reduced dimensions, it sure is quite expensive. This might be a deal-breaker, especially if you’re on a tight budget. Besides, the package does not include the seat, meaning you’ll have to purchase a branded one separately. This simply adds to the overall costs and, in turn, discourages potential buyers.

Type: Two-Piece Toilet | Shape: Elongated | Flushing System: AquaPiston Flush | Water Consumption: 1.28 GPF | Material: Vitreous China | Bowl Height: Comfort Height | Bowl Shape: Elongated | Seat Included: No
  1. K-6299-0 Veil Toilet Bowl

Now that we have reached the end of our list, we’d like to finish off with the K-6299-0 Veil Wall-Hung Elongated Toilet Bowl. If you want to take things to the next step by adding a modern touch to the bathroom, it’s time to replace the old-school, floor-mounted model with this next-generation unit.

The K-6299-0 Veil is truly one of its kind, providing an unparalleled user experience, both in terms of comfort and aesthetics. That said, if you detest cleaning the bottom of floor-mounted models and would rather keep things low-maintenance, this unit indeed checks that box and more.

Since it’s meant to be wall-hung, users can actually save on bathroom space and keep the area underneath clean and accessible. Furthermore, it has a one-piece configuration, meaning it combines both the tank and carrier in the same unit.

However, if you’re unsure about the comfort level, let’s just clarify that the elongated seat provides sufficient space and support for users of all sizes. Besides, you can set the bowl height anywhere between 15⅜” up to 28½” from the floor to get the ideal height.

Lastly, it includes a dual-flush actuator, allowing users to choose between a 0.8-gallon and 1.6-gallon flush, thereby keeping water wastage to a minimum.

We are, for most parts, satisfied with the performance of this unit, except for this one flaw in its function. The water sits pretty low in the bowl, and we would have liked it better if it was slightly higher. Therefore, at times, you may need to flush more than once to clear away bulk waste.

Buying Guide for the Best Kohler Toilet

Knowing all about the 7 best Kohler toilets may seem enough information to go ahead and buy one. However, you still need to figure out which one will work best for your washroom before proceeding with the purchase.

That’s why we have put together a brief buyer’s guide to walk you through some essential points. So, let’s get to that now.

  1. Configuration

When we talk about configuration, we’re essentially talking about the two types of toilets – one-piece and two-piece models. The latter is the traditional variety, which includes two separate parts, namely the bowl and the tank.

They’re usually heavier and require regular cleaning and maintenance. Meanwhile, one-piece models integrate the tank and bowl in one system, and they usually have a smaller footprint than their two-piece counterparts.

  1. Flushing Mechanism

This is the next thing you should check, and as such, it’s best not to skimp on flushing performance. That said, most models on our list are WaterSense certified, so you can expect high efficiency throughout.

However, you must also look for powerful and high-clearance flushing, as that will ensure bulk cleaning without any clogs. Besides, you’d want noise-free flushing action to avoid embarrassing gurgling sounds altogether.

  1. Style And Design

Each of these Kohler models ranks high on style and has distinctive features that separate one from the other. That said, if you’re looking to upgrade your bathroom, we suggest investing in a sleek and compact model with clean lines and a defined profile.

You’d also want to look for an elongated seat as it not only improves aesthetics but also provides more comfort and support.

  1. Toilet Seat Height

This may seem like a no-brainer, but the toilet seat height will determine your overall comfort level while sitting on the bowl. Therefore, you don’t want to make a mistake while choosing the ideal option. If you’re not too sure, it’s always better to opt for a higher model as that will accommodate most users.

However, if you’re shorter than average, you might want a lower seat to avoid climbing too high. No matter which product you buy, check the specs for the seat height and figure out what works best.

How does Kohler’s flushing system work?

Kohler offers several flushing systems, including gravity, pressure-assisted, and AquaPiston technology. Gravity-fed toilets use the natural force of gravity to flush the waste down the drain, while pressure-assisted toilets use air pressure to enhance the flushing power.

AquaPiston technology uses a canister design that allows water to flow into the bowl from all sides, ensuring a powerful, clog-free flush.

Are Kohler toilets easy to install?

Kohler toilets are generally easy to install, but it’s recommended to hire a professional plumber for proper installation. Kohler offers installation instructions and videos on their website, and some toilets come with a pre-installed tank and bowl for easier installation.

How do I clean and maintain my Kohler toilet?

To clean and maintain your Kohler toilet, use a mild, non-abrasive cleaner and a soft cloth to wipe down the surfaces regularly. Avoid using harsh chemicals or abrasive materials that can damage the toilet’s finish. It’s also important to inspect the toilet’s components, such as the flapper, fill valve, and flush valve, and replace them as needed to ensure proper performance.

Does Kohler offer a warranty for their toilets?

Yes, Kohler offers a warranty for their toilets that covers defects in materials and workmanship for a specified period of time. The warranty varies depending on the toilet model and can range from one to ten years. You can check the warranty information on Kohler’s website or contact their customer service for more details.


That’s all from us!

We hope you could find the most suitable Kohler product from our top recommendations. However, before you go ahead and place an order, here’s a piece of advice.

Make sure that the toilet offers sufficient room and does not strain your back or knee. After all, using the toilet should not turn into a stressful session. On that note, we’d like to sign off with a quick recap of our findings.

The 3810-0 Santa Rosa Elongated 1.28 Gpf Toilet is the best overall, and the K-3999-0 Highline Two-piece Elongated 1.28 Gpf Toilet is the best two-piece option.

Other than that, the K-3619 Cimarron Elongated 1.28 Gpf Toilet has the best features, and the K-5401-PA-0 Veil Skirted One-Piece Intelligent Toilet is the best premium buy.

Till next time!
