1. Kohler K-3754-0 Kelston – Editor’s Choice

Extra Room And Comfort

Kohler K-3754-0 Kelston

The Kohler K-3754-0 is yet another of its kind in this Kohler toilets collection. Talking about comfortability and efficiency, this one is among the leading in the market. It has an elongated bowl that provides the extra room and comfort that most adults always look for.

Moreover, it poses the comfort height feature that gives you a chair-height sitting arrangement. This feature makes it easier for an adult to sit and stand especially those afflicted with health complications such as arthritis. It’s an ideal option for tall people who have trouble reaching and standing from a low-seat toilet.

3-Inch Flapper

The bowl is relatively easy to keep clean thanks to the 360-degree water flow from the canister. The powerful AquaPiston flushing technology and 3-inch flapper might also reduce the chances of clogs.

1.6 Gallon Powerful Flush

The Kohler 1.6 gallon toilet flush makes it a good water saver although not the most efficient.

Perhaps the only setback is that its elongated bowl design limits it to spacious bathrooms. It does not ship with the seat also. This isn’t a con as such considering that you’ll now have the freedom to install any of the best bidets or padded seats right off the bat.

2. Kohler 3810-0 Santa Rosa – Premium Pick

Kohler 3810-0 Santa Rosa

One Piece Water Efficient Toilet

The Kohler Santa Rosa 3810-0 [link to a more in depth review] brings in new freshness and angle to the Kohler modern toilets family. It prides itself with a compact elongated bowl that offers the needed comfort while occupying the same space like our first two recommendations.

Another unique attribute is the comfort height. It provides a chair height seating which most adults want for their bad backs.

Also, it comes as a one piece toilet that makes the cleaning process much more manageable. This configuration also highly reduces the risk of toilets and should give you peace of mind.

1.28 Gallon Flush Rate

Again, the commode has an efficient 1.28 gallon flush rate that provides a performance comparable to 3.5 gallon flushing. This aspect will save you up to 16,000 gallons of water yearly on average.

7 Colors

If you love options, then you’ll be stoked by its 7 color schemes: biscuit, almond, black, white, dune, ice gray, and sandbar.

3. Kohler K-3987-0 Wellworth – Budget Buy

Real Solution For Small Bathrooms

Kohler K-3987-0 Wellworth

To start us off is the Kohler K-3987-0 [link to a more in depth review]. Made from a durable vitreous china material the cistern offers a real solution to those with small bathrooms, thanks to its round front bowl. Moreover, the round seat seems a bit wider than the average, thus improving the “aim” making it easy and fun to clean.

Dual Flush: 1.1 or 1.6 GPF

The dual flushing technology gives this toilet a touch of versatility. You are at will to choose between 1.1 or 1.6 gallons per flush. The lower choice (for liquid waste) saves you a great deal regarding water usage, thus reducing your monthly water bills. Who doesn’t like that?

Class Five Type Of Technology

Still, on the flushing aspect, it utilizes a class five type of technology. Water jets out in bulk from all sides of the bowl, powerfully sweeping away all the waste and leaving the bowl clean in one motion. As such, you might not need to pull the lever for a second flush.

4. Kohler K-3851-0 Cimarron – Water Saving Toilet

Kohler K-3851-0 Cimarron

Excellent Water Conserver

Lastly, we have the Kohler K-3851-0. This commode fills our number slot of the best 10 inch toilets. It shares an aqua piston flushing technology with the Kohler K-3754-0 which utilizes 1.28 gallons per flush making it an excellent water conserver.

Round Front Bowl

Other similarities to other members include the round front bowl and the comfort height feature. These attributes provide the same functionalities as outlined with the other family members.

10 Rough In Toilet

For those struggling with small bathrooms, this 10 rough in toilet and  it’s round bowl saves plenty of space lengthwise making it a really desirable option.

5. Kohler K-3977-7 Wellworth – Affordable Black Toilet

Powerful Flushing Performance

Kohler K-3977-7 Wellworth

Like its sibling above, the Kohler K-3977-7, has a round front toilet bowl, though different in color (the former is white). The round bowl provides a proper clearance, especially in small bathrooms.

Installing the system is a piece of cake. It is a three-bolt installation procedure and also comes with a detailed installation guide to guide you through the process. But in case you get stuck, this guide on how to replace a flange will take you through part of the process as well.

1.6 Gallon Flush

The Kohler K-3977-7 has powerful 1.6 gallon flush that gives you a reliable and robust performance. The downside is that you have to order the seat separately; it doesn’t come in the same package.

Its price and functionality are best suited for those who need a decent commode without breaking the bank, especially if you’re into black toilets.
