Features To Consider

Choosing a toilet for your bathroom is not an easy task! Toilets have so many features it can become overwhelming to make a choice. Before you stress too much about your decision, look at some of these features to consider before you buy a one-piece toilet.

Bowl Shape

Toilet bowls come in either a round shape or an elongated shape. Round toilet bowls take up less space and are ideal for small bathrooms or powder rooms. Elongated bowls require more room, but they also offer more seating surface which adds more comfort to your toilet experience. Elongated bowls are also more accommodating for larger individuals.

Bowl Height

I always thought that toilets were pretty much one size fits all. This is not true! The standard height of a toilet is around 14-inches from the floor to the top of the toilet rim.

There are also toilets that have chair-height seats. These toilets are slightly taller than the standard toilet and measure around 17-inches from the floor to the top of the toilet rim. 

Chair-height toilets are easier to sit down on, especially for elderly people. They are closer in height to an actual chair that you would find in the dining room or living room of your home.

Flushing System

Toilets have either a single flush mechanism or a dual flush system. The only difference between the two styles is that a dual flush system allows you to use a partial flush to save water and dispose of liquid waste. If you want to conserve water, then consider getting a dual flush toilet.

FAQs

Benefits Of One Piece Toilet?

Most one-piece toilets have a very compact design. They often have a skirted trapway which means the exterior of the toilet is very easy to clean. There are also no gaps or joints between the toilet tank and the bowl so the toilet tends to be more hygienic.

Why Buy A One Piece Toilet?

One of the biggest advantages of buying a one-piece toilet is the lower maintenance associated with the toilet. There are no joints that could potentially leak, and they are much easier to clean. One-piece toilets tend to fit better in smaller spaces.

What Is Better One Piece Toilet Or Two?

Although two-piece toilets are the most common design found in homes today, they tend to take up more room in your bathroom. The tanks are usually taller, and they often require more maintenance. If you want a low maintenance, easy to clean toilet, then consider a one-piece toilet.

How Does A One Piece Toilet Work?

One-piece toilets have a toilet bowl and a tank that are fused together into a single piece. There are no joints connecting the bowl and tank which means less maintenance and risk of leaks. A one-piece toilet flushes exactly the same way as a two-piece toilet. 

How To Install Flush Valve On Kohler One Piece Toilet?

Most Kohler one-piece toilets have a canister-style flush valve. This is the part of the tank that allows water to move inside the bowl. To install a canister flush valve, you must follow these steps:

• Turn off the water supply and drain the tank.
• Remove the flush valve retaining mechanism.
• Install the new valve and flush valve gasket in the reverse order you removed the original mechanism.
• Be sure to apply some dish soap between the flush valve gasket and flange.
• Connect the trip lever chain.
• Turn the water supply back on.

How To Install A One Piece Toilet?

A one-piece toilet is installed very similarly to the way a two-piece toilet is installed. The only difference is that one-piece toilets are a bit more difficult to handle since you are dealing with a single fixture. Installation is typically quicker, however.

• Install the closet bolts into the slot in the flange and secure the bolts in place.
• Turn the toilet upside down.
• Place the wax ring over the toilet horn in the middle of the toilet base.
• Carefully lower the toilet base onto the floor flange and align the closet bolts with the holes in the toilet base.
• Gently but firmly press the base down on the wax ring.
• Be sure the toilet base is level and then install the washers and nuts on the bolts.
• Cover the bolts with trim caps
• Install the flush mechanism.
• Install the toilet seat.
• Connect the water supply.
• Test your connections!

Since most one-piece toilets have skirted trapways, the bolt holes are hidden inside the toilet “skirt”. The hardest part of the installation is aligning the bolts with the holes in the toilet! Remember to be patient, ask for help, and be persistent. You will love the results when you are done!

Conclusion

Only you can decide what type of toilet will suit your needs the best. Before you make a choice, consider the product reviews we provided and the list of features to think about. Regardless of which toilet you choose, you will end up with a beautiful fixture that will complement your bathroom and turn it into a sleek and sparkling room!
