1. Sterling 402375-0 Stinson – Editor’s Choice

Offers Much-Needed Comfort And Space

Sterling 402375-0 Stinson

With an inbuilt pro force technology, the Sterling 402375-0 offers sufficient power to deal with anything that comes its way. You only need a single flush.

On the other hand, the elongated bowl with an extended rim offers the much-needed comfort as it provides more room and space to sit on. I imagine this might suit people with larger-than-average bodies.

1.6 Gallons Per Flush

Also, the toilet will save you gallons of water on average, since it only consumes 1.6 gallons of water per flush. Not only that, it meets the current strict water conservation standards which translates to a double score. You save money and the environment too.

Installing the cistern isn’t a tricky affair, it has a three-bolt quick-connect installation system. This eliminates the need of tagging a plumber along especially if you know the basics.

Not to forget is that the non-porous and glossy vitreous China body guarantees you that the fixture may offer you excellent services for decades on end.

2. Sterling 402025-0 Karsten – Premium Pick

Incredible Dual Flush Performance

Sterling 402025-0 Karsten

For those with small bathrooms and in need of an elegant commode, then the Sterling-402025-0 fits the bill. It is built with an incredible dual force flushing technology, that allows you to choose between a 0.8 and 1.6 gallon flush mode. The 0.8 is meant for liquid waste while the 1.6 is for solid waste.

Moreover, its round front bowl comes in handy to those with smaller bathrooms since it gives you enough clearance at the front.

Good Looking and Easy To Use

The two button actuator breaks the monotony from the common lever appendage. Besides, the button is atheistically good looking and easy to use.

From the customer’s reviews, we get that the system is excellent as said and not a marketing gimmick. It is quiet and efficient in its operations.

In most instances, it clears all the waste without leaving a mark or residue, thanks to the robust flushing system and the hard glossy finish.

3. Sterling 402078-0 Windham – Budget Buy

The Large Water Surfaces Reduces the Amount Of Odor

Sterling 402078-0 Windham

Next up is the Sterling 402078-0. It is an excellent and sturdy cistern that utilizes an optimized siphonic flush action to get rid of bulk waste. Moreover, the smooth, glossy surface leaves the bowl sparkling thereby eliminating the need of holding the toilet brush each time you have a bowel movement.

Installing this commode may be a breeze as most users report that their commodes came preinstalled. All you have to do is aligning everything, and then tighten up the fixture.

While several homeowners report that their package included the installation hardware, others report that they did not get the installation kit.

Plan For Wax Ring, Two Flange Bolts and Water Supply Hose

Therefore, it might be safe to plan for the wax ring, toilet seat, two flange bolts, and a water supply hose.

Large 9×8 Inches Water Surface

Also, of noteworthy is the large 9*8 inches water surface that helps keep the bowl clean and reduces the amount of odor. This saves you unnecessary embarrassment.

The grade A vitreous china material used for its construction suggests durability. It also has an easy to flush procedure thanks to the two-button actuator which also adds some sleekness to its design.

What To Look For When Buying A Sterling Toilet

There is more to consider while searching for a toilet. For instance, you could look out for things such as the flushing technology. You need to ensure that it won’t bring clogging issues especially if you have a busy home.

Bowl Design

The bowl design might be key depending on the size of your bathroom and your perception about the level of comfort that the elongated and round-front bowls offer. If you have a small bathroom, then a round-front model might suit you. If you feel that an elongated bowl offers a better stand and won’t fill your bathroom to the gills, you have our blessings, go for it.

Water Usage

Moreover, take an analysis of the amount water the system uses. Are you looking for a HET model? Look out for the water sense label. The good thing about modern commodes is that the WaterSense label is conspicuously displayed.

Single or Dual Flush Toilet

Again, is it a single or dual flush commode? Remember that while a dual flush fixture sounds a little bit more water efficient (which is cool), it could lead to water wastage if the users don’t know how to use it.


Your comfort is paramount. Does the standard 15-inch tall toilet give you trouble due to its low-profile design? Check out for an ADA compliant fixture. These thrones have a height of 17-19 inches and may help with your back issues.


All these will go a long way in helping you to avoid incurring massive bills regarding water usage, maintenance, and repairs, besides ensuring that you find a commode that best suits your situation.

Of utmost importance, don’t forget to compare Sterling products with other brands that we’ve reviewed here including Kohler, Toto, and Niagara.
