Consider This Before Buying a Sterling Toilet

Sterling toilets and components by Kohler offer serious quality and visual appeal. Even so, you still need to choose the right product for your toilet installation or replacement project.

As you may have noticed, Kohler produces an array of toilet types and designs, including wall-hung, low-level, one-piece, and even the traditional toilet designs. With that said, let’s look at some factors to consider.

Toilet Design

Just as is the case with some of the leading toilet brands, most of the Sterling toilet model features a two-piece design.

Although two-piece toilet designs are more affordable, they are not the only toilet design in the market.

Two-Piece Toilets

These are the commonest toilet design in the industry, featuring a toilet seat and a tank as two separate units.

Their preference for other toilet designs may be attributed to the fact that they are cheaper. However, they are harder to clean and tend to accumulate dust in between the bowl and the tank.

One-Piece Toilets

These come as a single unit, where the toilet tank and toilet seat are fused together. Other one-piece toilets do not have a toilet tank altogether.

Such models are connected directly to the plumbing system, hence they are only suited for houses with high-pressure water supply lines for enhanced flushing efficiency.

Regardless of the type, one-piece toilets are comparatively costlier and harder to install. A considerable number of homeowners find one-piece toilet designs to be sleek, and modern. You will also find one-piece toilets easier to clean.

If you can afford them, Sterling one-piece toilets are the best option for both modern and contemporary bathroom decors.

In-Wall Toilets

The best Sterling in-wall toilet models require a tank to function. However, the tank is usually installed on the wall behind the toilet. Since the tank is concealed in the wall, such a toilet design will give your bathroom a sleek, minimal profile.

Such a model is also suited for smaller bathrooms as they are known to save a considerable amount of space. As compared to other toilet models, in-wall toilets are relatively costlier to acquire and install.

Integrated Base Toilets

In addition to traditional toilet models, Sterling also offers one-piece and two-piece toilets with an integrated base. A toilet with an integrated base features a full, flush piece bottom.

Similar to other toilet brands, Sterling toilets with an integrated base are costlier than their conventional alternatives.

However, Sterling integrated-base toilets are a great upgrade as they are visually appealing and comparatively easier to clean.

Flush Mechanism

Sterling uses different flushing mechanisms in ita toilet models. In addition to ease of use, the flush mechanism used on a toilet also determines its flush efficiency and water consumption.

Each of the flush mechanisms in use today has its set of benefits and downsides, as explained below.

Pressure-Assisted Toilets

In their functioning, Sterling pressure-assisted toilets apply pressure that builds up inside the water tank to push water down. This results in a thorough bowl cleaning action as compared to other flush mechanisms.

Pressure-Assisted Toilets are also known to reduce water consumption by the toilet by up to 45 percent. Although noisier in operation, the best Sterling pressure-assisted toilets are relatively easy to clean.

Gravity-Feed Toilets 

These mainly rely on the force of gravity and the weight of water flowing down to clean the bowl. Own to their simplicity, they are some of the most affordable toilet options in the industry. As compared to pressure-assisted toilets, gravity-feed toilets are less noisy in operation.

Dual-Flush Toilets

This is essentially a variation of conventional flush toilets that are equipped with two flush buttons or levers that flush different amounts of water.

As compared to siphon-action models, Sterling Dual-Flush toilets are fitted with a larger trapway. As such, most of them employ a wash-down flushing mechanism.

Dual flush toilets are preferred for their superior water efficiency. The wash-down mechanism used by the toilets only requires a limited amount of water to flush efficiency.

Of the two flushing button or levers, one releases a larger volume of water and is used to flush away solid waste. The other button releases a smaller volume of water to the bowl and should be used when flushing liquid waste.

With such a flushing mechanism, you will be saving a considerable amount of water with every flush and avoiding clogging with a larger trapway.

Seat Height

The seat height is the distance between the bathroom floor and the top of the toilet basin.

Under normal circumstances, you should just go for the height you find comfortable.

If you have an aged or disabled person in the house, you should go for the taller toilets, preferably the 19-inch Sterling toilets.

If you do not find a toilet to suit your height requirements, you may also opt for the wall-hung Sterling toilets. With these, you can alter the installation height to suit your specific requirements.

Our Final Verdict

Sterling—a Kohler company—is one of the leading manufacturers of plumbing products, such as toilets. With a vast range of toilet models, you’ll need to figure out which one is best suited for your installation or replacement project.

Choose a Sterling toilet model that offers the right seat height, water efficiency, as well as toilet configuration and size. Finally, consider your own styling and comfort preferences, as well as the budget. Ready to buy a Sterling toilet? tell us which model works for you!
