With the bountiful availability of elongated toilets flooding the market, it’s always nice to have a bit of an alternative choice. And that’s exactly what this model provides with a rounded front bowl. Both have their advantages, and this one in particular is designed to take up less space, making it ideal for those of you wanting something that’s compact for smaller sized bathrooms.

In addition to this, the glossy finish goes well with the siphon action flush, to produce a clean bowl, effectively removing waste using just 1.28 gallons with each flush. A sensible, environmentally friendly option that makes great water savings over the course of a year. Includes a trip lever to push waste out rather than buttons.

The water surface at the bottom of the bowl measures nine by eight inches, which is larger than average and is specifically designed to keep odors down and to a minimum.

All in all, this is a low budget option, that isn’t particularly large, and maintains a decent feature list making it a suitable option for home usage.

Again, you’re looking at a WaterSense compliant toilet that, according to the manufacturer, may enable you to save up to twenty four thousand gallons of water on the lower flush setting.

The simple, yet effective dual flush technology gives users the option to deal with differing types of waste differently. You can use the zero point eight option for liquid, and one point six which is probably more effectively used for solid and bulk waste that requires a little more power. This operates on a two – push button system located on top of the tank.

The rounded front ensures it will make good use of the installation area and save space.

An additional inclusion is the sanitary guard which has a job in ensuring liquid doesn’t get to places it shouldn’t such as under the tank.

Slightly more expensive than the toilet above, but still a good amount listed in the specifications to offer decent flushing performance, and Eco friendliness.

An elongated model providing a nice, white, minimalist design that’s both elegant and stylish. Certainly an option for the modern bathroom and fans of two piece units.

Looking at the main feature list, we see that it uses up to 1.6 GPF and runs on a siphonic flush which has been known to do a good job in the bulk removal of waste. The jury is out on whether that is the case on this model,  but in the past that has held true. Flush is activated via use of trip lever attached to the tank.

User comfort is always something we look into, and the fact that it’s ADA compliant says a lot about the design as they are generally taller and more accessible than traditional toilets.

It’s not particularly large either, measuring 29 inches by 17.4 inches by 29.9 inches.

With the price tag reasonably affordable, and a five year limited warranty policy, this could be an option worth researching into further.

Ranges from this brand

Like several of its competitors, you will run into all kinds of ranges, each offering their own features and unique to one another. Some of the more popular ones include Rockton, Stinson, Karsten, Windham, and Riverton.


With it falling under the same company as Kohler, you can expect some similarities. But some differences too. Overall, They offer an excellent amount of choice from elongated, to rounded, differing colors, and various design styles. We recommend our readers take time to compare these products with the various other brands we review before you make any concrete decision to purchase a new toilet.

One thing you may notice is that there isn’t quite as much feedback as some of the market leaders on various online shops. Whilst opinions and consumer experience should play a role in your decision, they are not the be all end all. Taking time to look at the specs and understand the flushing technologies can make a huge difference and may potentially save you money down the road.
