What Is a One Piece Toilet? 

As the name suggests, one-piece toilets are commodes whose toilets and tanks are fused in a continuous design. They are devoid of any joints and crevices. These commodes are also commonly known as single piece toilets which were first developed by British inventor Thomas Twyford in 1985.

On the other hand, if the toilets and tanks are disconnected and need to be fitted together, they are known as two-piece toilets or coupled toilets.

Why Buy a One Piece Toilet? 

Both one-piece and two-piece toilets have identical features. So, should you go through all the trouble searching for the one-piece toilet, when you could get the two-piece toilet at a lesser price?

The answer is always, yes! Single toilets have come a long way from their original design of 1885 and have amazing functions to look out for. 

  • Comfort Height

While seat comfort is always a priority when it comes to toilets, the height also influences the user experience.

The toilet bowls of the one-piece commodes is usually situated 17-inches off the ground which provides sturdy back support to your back and knees. This will help greatly if you have elderly people in the house or people with physical disabilities. If you confused with the right height of your toilets, follow this guide –

Comfort Height vs Chair Height vs Standard Height Toilet – Which One to Pick?

  • Easy to Install

A little bit of DIY experience would go a long way when it comes to setting up single piece toilets. Fewer parts mean lesser attachments to stress you out. And because of its ergonomic design, you don’t need to hire a plumber or handyman to tighten the tank to the toilet bowl. 

  • Space Saving

Most of the models are generally smaller in size and are a spectacular fit for tiny bathrooms. The difference isn’t much but combined with a sleek design and wall-hung tankless options you can save sufficient space. Your bathrooms will feel airy and less stuffy. 

  • Water-Saving

Dual flush systems are a common feature of many single commodes. So, you can choose the low or high-powered flushing mechanism and control the amount of water released. This makes the toilets very eco-friendly and energy saving, especially if they have a WaterSense seal. 

  • Easier to Clean

Because of the seamless design and lack of crevices, joints and nooks, the single-piece toilets are hassle-free to clean. This also entails a lack of breeding ground for disgusting mildew and bacteria.

  • Durable

Since the one-piece designs do not need any additional fittings, they are easier to maintain. The materials used increase the sturdiness of the fixture and prevent cracking and splitting. 

  • Less Maintenance

Because of the fused layout, there will be fewer possibilities of breaking down and leaking from the joints. So, fewer things for you to worry about!

  • Less Shipping Problem

While the all-one-piece units are heavier and larger than the two-piece toilets, shipping for it, on the other hand, is less troublesome. You won’t have any mismatched or lost parts when the attachments are sent separately. 

  • Scratch-less

The exterior of the single-piece units has a glazed finish which is resistant to stains and fading. It also prevents particles from sticking, so you will get a shiny and clean outlook even after many years of use. 

  • Leakless

Water seeping out of the toilet is one of the most annoying things to come across. It could be because of faulty wax ring. But with a closed-up toilet, there will be fewer joints and openings for that to happen. 

These are some of the many advantages you can get from a one-piece toilet, which outweighs whatever drawbacks you might come up with. 

Final Words

Toilets aren’t something you shouldn’t skimp on. They are permanent fixtures of your home, lasting for decades at a time if not more. So, consider the factors of what would be the right toilet before you make a purchase. Investing in the best one piece toilet should save you money and stress, not bring in more trouble.
