One-Piece Toilets Buying Guide


Picking the best one piece toilet (or two) for your home is one decision that you will have to make at some point. It is crucial that you get this decision right the first time, so as to make every visit to the bathroom a relaxing and comfortable one. Here are some things you should consider before choosing a one-piece toilet for your bathroom:

Size

The size of your bathroom determines the size of the one-piece toilet you should buy. If you have a very spacious bathroom, you can get any model. However, if your space is limiting then you need to pick smaller sized toilets.

If you go for the bigger toilets, understand that they may not be as portable as the smaller varieties, and cleaning is a little hectic.

Comfort

Whichever toilet you decide to get, always remember that you will be stuck with it for several years. Therefore, it has to be comfy. Different features affect how comfortable a toilet is. These include the seat’s height, how easy it is to use and clean, and the ease of installation.

Apart from the comfort offered by the best one-piece toilets, one other essential thing to look at is the bathroom’s overall comfort. A toilet that fits perfectly into your bathroom makes it clutter-free and inviting.

Flushing System

There are many flushing system options on the market, so selecting the right one may prove to be a little tricky. It is reasonable to expect that some of these flushing systems are not as good as others. The minimum requirement though is that the toilet should be able to handle any waste.

The flushing system used by a toilet sometimes determines how efficient it is in disposing of waste. G-Max, Double Cyclone, and the Dual Flush system toilets are some of the most effective technologies on the market. Make sure you confirm the flushing ability of the toilet before purchasing it.

Price

Your budget is one of the biggest determining factors if you want to purchase the best 1piece toilet. Full disclosure, one-piece toilets are more costly than two-piece types because of their efficiency. For instance, they use less water, flush effectively, and some do warm up your butt (ahem). Most of these features are not easy to find in two-piece toilets. So the bottom line is this: prepare to spend a bit more if your obsession is on the one-piece types.


Frequently Asked Questions

They are becoming more popular nowadays. They fit even in small bathrooms, are easy to clean, and look great. Check out these frequently asked questions about this type of toilet:

1. What are the advantages of one-piece toilets over two-piece toilets?

Some of the benefits you will get from using a one-piece over a two-piece toilet include:

  • Installation – One-piece toilets are generally easier to install than two-piece toilets. This is mainly because they have fewer parts to put together.
  • Size – Most one-piece toilets are a bit smaller than two-piece toilets because of their compact nature. This makes them excellent choices for small bathrooms.
  • Cleaning – The skirted bowl featured in toilets covers many gaps found in standard toilets. These gaps are usually home to dirt, bacteria, and dust, but a one-piece toilet’s smooth surface prevents microbial growth.
  • Durability – It is generally believed that the fewer the parts a toilet has, the easier it is to maintain, and the higher the durability. One-piece toilets are, well, one piece of ceramic, which means they have fewer elements exposed to moisture and other factors that may cause damage. This makes them generally more durable than two-piece toilets.

2. Is there any disadvantage in using a one-piece toilet?

One-piece toilets are preferred to two-piece toilets because of a number of reasons. However, one significant disadvantage is that one-piece toilets have over two-piece toilets, which is the price. One-piece toilets generally cost more than two-piece toilets because of their more robust construction and sleek appeal.

3. What is the best one-piece toilet to buy?

Well, according to toilet gurus and user reviews, the top choices include WoodBridge T-0008 Luxury Bidet Toilet, ToTo MS604114CEFG UltraMax II, Toto MS854114S#12 Ultramax toilet, TOTO Ultramax II Het Double Cyclone Toilet and Kohler 3810-NY Santa Rosa Elongated 1.28 GPF toilet.

4. Can you replace a two-piece toilet with a one-piece toilet?

Yes, you can install a one-piece toilet in a place where a two-piece has been removed as long as the dimensions (including those of rough-in) match. If the dimensions don’t match, then you may find yourself spending more than you expected on this replacement project.


Conclusion

There are many one-piece toilets you can go for. Each model is likely to vary from another based on things like water consumption, design, or performance. This means you need to give a damn a bit about what you are going for. Make the final choice based on the bathroom experience you are looking forward to.

The best one piece toilets are an excellent choice for several reasons. First, they are compact, making them suitable for small bathrooms. Secondly, they are also easy to install and maintain. Another huge advantage is that they use way less water than earlier models.

  1. My home is quite old, and some of the features reflect its age. One of those features is the toilet in my guest bathroom, and I think that it’s finally time I get an upgrade. Thanks for pointing out that if you get a water efficient one then you can use only 1.28 gallons per flush as opposed to the typical 1.6 gallons. I’ll have to try to get an efficient one as I look for a toilet replacement.
