Best One-Piece Toilet For 2021 (Reviews and Comparison)

This site contains affiliate links to products. We may receive a commission for purchases made through these links.

One-piece toilets are beneficial for many reasons. The first and main reason is that they have fewer crevices that collect odors, dust, and other dirt, making them very easy to keep clean and to sterilize.

The second selling point for one-piece toilets is that it is one unit, and looks a lot more modern than toilets that have their tank and bowl separate. One-piece toilets do tend to be a little bigger, although these days there are some very sleek and elegant-looking designs to choose from.

Choosing the Best One-Piece Toilet For You

  1. Size

This may be a kind of obvious feature, but one you are likely to forget when you are inundated with design options to choose from. You want the toilet to be the right size for your bathroom, which includes a few physical parameters to consider in your choice.

Do you need a tall toilet? Does the toilet need to fit into a narrow space? How far away do you want the toilet to be from the wall? (This measurement is called the ‘rough-in’ measurement)

  1. Technology

Do you want a super silent toilet? Or a self-cleaning toilet? Maybe both? If your bathroom is next door to your children’s rooms, you will probably want to consider a toilet that is silent so that it doesn’t wake them in the night.

  1. Eco-Friendliness

How much water does the toilet use per flush? We are all a little more aware of wasted water and energy these days and opt for the most cost-effective and eco-friendly options on the market, so why shouldn’t your toilet be too? The majority of new toilet designs are already built with this in mind while maintaining a strong flush.

What We Don’t Like About Swiss Madison Well Made Forever SM-1T803 Chateau One-Piece Toilet
