American Standard 2876.016.020 Yorkville


Yorkville

As some of you will be well aware, the AS brand has quite a good reputation in this industry. Manufacturing some outstanding toilets as well as other bathroom accessories.

This model from the Yorkville range offers some great features that has earned it plenty of positive feedback from consumers to date. Among the feature list is the siphonic jet flush that operates on a pressure assist system for improved flushing power and performance to make light work of removing waste from the bowl.

However, for all its qualities, it's not particularly water efficient, using up to 1.6 gallons per flush to wash the bowl down.

Externally, the design is pretty standard, but looks clean, and comes finished in white. It includes the added comfort of having of an elongated bowl shape. The chrome trip lever is found on the front of its tank and the EverClean surface helps ward off bacteria and odors as well as making cleaning tasks simpler.

The main flaws that stand out immediately however, are that this doesn't include a seat, which will have to be chalked up as an additional cost in your calculations and planning.

Kohler K-3652-0 Barrington


Barrington

This is a two piece design from the Barrington range of KOHLER. Features an elongated bowl opposed to the round front style, alongside a nice white finish.

The pressure style flush will work well for consumers wanting more powerful performance in a busy family household. Some people associate power with additional water consumption, but that's not always the case. Many modern designs fall into the WaterSense category and still produce a highly effective flush. The K-3652-0 is one of them with 1.0 GPF usage, which has both economical and environmental advantages.

The trip lever is located on the left hand side of the tank and has quite a standard design. It also comes with limited warranty coverage for one year.

A decent unit, but also one that you may have to dig a little deeper into your pockets to get your hands on.

GERBER PLUMBING 21-375 581914


GERBER

Gerber produce a variety of differing fittings for the kitchen and bathroom. This particular toilet has a more accessible design thanks to its ADA bowl with a seated height of seventeen inches. A great options for users with joint and muscle pain or even senior users.

The bowl itself is of an elongated style, notable for its comfort, and the exterior is smooth for the most part, which brings a bit of simplicity to the cleaning process.

This is a floor mounted, rear ejection model. Which provides stability and a heavier flush without using up too much water.

It's not overly expensive for this style either, on the contrary, we feel it sits somewhere in the middle of the budget ranges on the market. It could be a smart alternative for those wanting more accessibility in your bathroom.

Considerations before you buy


In many cases, your residential plumbing system and pipes are already fitted and ready to go, and quite often they are built for floor mounted models as opposed to back flow toilets. And where there is less structures in place to accommodate this style, there is less demand. Which has a knock on effect and can limit the amount of choice consumers have due to them not being as widely manufactured.

On a more positive note, we're of the opinion that the exterior design is better due to the smoother lines and the concealed trap that they often come with. Of course, this also means there is far less nooks and crannies to reach which is great for people who like to keep their bathrooms clean.

On the whole, you'll be pleased to find that they're equipped with more powerful flushing mechanisms thanks to pressure assisted flush.

Be aware that some of these products are known to lack the stability when compared to various floor mount units. The main problems arise after consisten usage over long periods of time. You'll find in several cases units bolted to the wall come loose easier. A good way to counter this is to ensure you check the bolts and screws every so often, as we outline in the maintenance guide.

Some people believe they are more prone to leaks than traditional styles due to the complex nature of fitting them as well as the extra fixtures and attachments.
