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:


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.


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.


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.
