The Best One-Piece Toilets

One-piece toilets are becoming more popular because they have a more sleek, modern look than traditional toilets. Most one-piece toilets have skirted trapways that hide the plumbing connections and provide a smoother surface for cleaning. The downside of a one-piece toilet is the installation process. The bolts and connections are often hidden inside the skirted trapways making it more difficult to line up the bolts on the floor.

How to Choose the Right One-Piece Toilet

It used to be so simple to choose a toilet for your bathroom! Traditional toilets have similar features and mostly vary in color and shape. Now, toilets have different options available to set them apart from the competitor’s products from flushing mechanisms, flushing power, seat height and more. Here are some features to consider as you search for a new one-piece toilet for your bathroom.

Round versus Elongated Bowl

Round toilet bowls typically require less space and take up less room in your bathroom. They are ideal for small bathroom or powder room installations.

Elongated toilet bowls have more room and therefore provide added comfort for all users. There is more surface area available in an elongated bowl, and the size makes it more accommodating for larger individuals.

If you want a toilet that gives you more room and comfort, consider switching to an elongated bowl.

Toilet Height

You can determine the height of a toilet by measuring from the floor to the top of the toilet rim. Standard rim heights are around 14-inches to 15-inches from the floor.

If you have family members that are very tall, then consider a toilet that has a chair-height seat. These are typically around 17-inches in height or even taller.

Toilets that comply with ADA guidelines have a toilet height that ranges from 15-inches up to 19-inches.

Flushing Systems

There are different types of flushing systems available in both one-piece and two-piece toilets. The basic flushing system available is standard gravity flushing. This method uses the force of gravity to create a siphon during flushing. This type of flushing system is generally easy to repair and is the cheaper option available.

Some toilets have a pressure-assisted flushing system. This type of flushing system uses a special mechanism within the tank to create a siphon-jet action. It produces more forceful flushes than the typical gravity toilet and is less likely to create clogs.

Dual flush systems use a larger diameter trapway for flushing away water waste. These types of systems are not prone to clogging and usually use less water to flush efficiently. The dual flush systems often require more cleaning to ensure all waste is disposed of through the flushing cycle.

Installation

One-piece toilets that have a skirted trapway are the most difficult to install. The skirted trapway essentially hides all plumbing and installation connections. This causes challenges in installation as you cannot easily line up the bolt holes and connectors while holding a toilet that weighs nearly 100 pounds or more.

One-piece toilets without a skirted trapway are easier to install and more closely compare to the installation complexities associated with a two-piece toilet.

When choosing a one-piece toilet, be sure you understand the installation process so you can determine if you will require a professional plumber to install your new fixture.

Conclusion

One-piece toilets have a variety of options available that can increase or decrease the cost of the fixture. Only you know which toilet will best suit your individual needs for your bathroom upgrade. Before you make a choice, consider the product reviews we have provided and some features such as bowl shape and flushing mechanism. Any choice you make will immediately upgrade your bathroom to a spa-like experience!
