What Is A One Piece Toilet?

If the toilet and tank are intermixed together without any parts, then the toilet is known as one piece toilet. It is known as single piece toilet also.

If the toilet and tank are separate and attached using fittings, then it is known as two-piece toilet. It is called as coupled toilets also.

One Piece Toilet Advantages:

One Piece toilet has almost similar functions with two-piece toilet, then it’s a burning question- why should customers select One Piece rather than two-piece toilet? Especially, the price of a One Piece toilet is more expensive than a two-piece toilet.

Ok, let us know how One Piece toilet came to the world. One Piece toilet was firstly innovated in 1885, Thomas Twyford.

Earlier it was not as modern design and function as today. It already had the U-shape trap design, but the tank was dangling high on the wall like a pull-chain toilet. But nowadays, Best one Piece toilets 2021 have these amazing functions:

  • Easy installation system– due to its One Piece design system, the owner or the plumber does not need to attach the tank to the bowl anymore. You can follow our article its help to install a new toilet “how to install a new toilet
  • Small on size – one of the good things of it saves a lot of space in your bathroom as well as gives a modern look. To be honest, if you choose the wall hung model, as well as the tankless design, can save you tons of space in your cloakroom.
  • More Easier to clean – having no crevice or joint between the water tank and bowl, the one-piece toilets are way easier to clean compared to a two-piece toilet.
  • Less maintenance – because of the single-piece toilet’s tank and bowl are attached together, so there’s less possibility to break down.
  • Less shipping problem – 1 piece toilet always shipped as a whole product, unlike a two-piece toilet needed to be sent separately, and often time causes a lot of problem in the shipping process.
  • Comfort height – normally, the bowl sit is at 17 inches than 15 inches

What to look for when buying a toilet

Toilet design:

A toilet can change the interior home design and it also represents your personality. So always keep in mind when want to set up your toile- where it will be set up and how it will be looking your bathroom.

If you are going to put in a second toilet for your basement or by the garage, the design may not matter that much. But if you going to fix it in your dreaming resort then you need to think about your bathroom design. Also if you want to give a new and elegant look in your cloakroom then you will definitely go with a 1 piece toilet

Water usage: high-efficiency toilets vs regular dual flush toilets:

A lot of good efficient toilets are available on the market right now. All the machine mechanism tries to minimize the uses a lot of water. Around 30 to 40% of all water usage in American homes for the purpose of a latrine. Companies are trying to get a new eco flush toilet can cut your water spending back by no less than 25%.

If you live in a state like California, where toilets can’t use more than 1.28 gallons per flush you do not even have your own choice and have to limit yourself to looking at just low flush toilets.

There are two types of low flow toilets:

  • High-efficiency toilets
  • Dual flush toilets.

High-efficiency toilets always use only 1.28 gallons of water per flush, while dual flush toilets give you the option to choose between flushing-little delivers with 1.28 gallons of water and big delivers with 1.6 gallons of water. So, always you have chosen a toilet that most efficient toilet. Otherwise, you can give yourself a little freedom and chose a dual flush toilet.

Toilet Prices

It’s important – you have to keep in mind about your budget planning when you go toilet shopping. As our previous experience, expensive toilets are not always the best toilets. There are a lot of cheap toilets or affordable toilets in the market that has all the features and qualities you need. So don’t let dazzle yourself to see the cover of the topper. Keep away yourself by some extra bells and whistles or fancy descriptions but stick to the toilet cost you have in mind.

Macerating vs standard toilets

Standard toilets have an S-shaped waste pipe as they send the waste down into the sewer, a cesspool or another wastewater system. Macerating toilets, on the other hand, the first mold whatever’s being flushed into a pap, which is then being pumped into the waste adjustment system.

Because macerating toilets do not depend on gravity or an exploitation system, they can be placed level to the waste pipe or even below it. This advanced mechanism, as well as their flexible placing options, make macerating toilets more expensive than standard toilets.

 Toilet Height

The standard toilet height of toilet -14 to 15 inches high measured from the floor up to the top of the toilet bowl, the seat not included. This is fine for small and average height people. But taller people, elderly people and people with physical problems often prefer a higher toilet.

In this fact ADA (Americans with Disabilities Act) standards, toilet seats need to come 17″ to 19″ above the floor, which, for most seats, means the toilet needs to measure at least 16.3″ up to the top of the bowl.

When you prefer a high toilet, look for a toilet that is ADA-compliant or these as categorized as a Right Height or Comfort Height toilet.

Flush type

There are various types of flushing you can go with gravity flush systems, pressure-assisted flush systems as well as macerating toilets.

A gravity flush toilet depends on gravity to attraction the water from the toilet tank into the toilet bowl, thus siphoning whatever’s in there down. Since there are no extra mechanics involved, this is one of the quietest flushing systems I have ever seen.

A pressure-assist toilet has a tank which tops up with water in such a way that air pressure can put in. When you switch on the flush, the pressure shocks the water down the bowl to get rid of clogs in there. Because of the blast created by releasing the pressure, these toilets tend to be a bit loud than the ones with other flushing systems.

Elongated or round toilet bowl

Toilet seats come in the market place with many sorts of materials, but the most important things you have to keep in your mind to choose your Best toilet seat is whether you want an elongated one, or around one. Most manufacturer’s companies will not include the seat in the toilet price and with some models. In this time you have the option in your hand to choose whether you want an elongated or a round seat for your toilet.

You will have to make sure it fits on the bowl that you are going to pick up for your bathroom and thus get either a round or an elongated bowl depending on your seat comfortable.

Elongated toilet seats are elliptical or egg-shaped, being a few inches longer than round seats. Some people find them more comfortable. But if your bathroom is narrow space then it blocks the door from being able to open easily. people take up a bit more space so that’s something to consider about the elongated toilet seat.

Tanked vs tankless toilets

Maximum toilets designed with a tank, although it’s not always visible. For example, wall-hung toilet. These toilets have a tank system that’s tucked away in the wall. If you want to install this model, then it requires a little more break work in an existing and not a newly built bathroom, but it can be interestingly set up within limited space.

Macerating toilets are truly tankless when they pump water directly work into the bowl to then suck it out, straight into the macerator.

Compare toilets and read reviews of toilets

A lot of toilets design offer in the market place. All almost all of the features of the toilet still be different that you are looking for. So make sure to compare them and read reviews of toilets you’re interested in online, like the ones I’ve put together here for you.
