FAQs
What’s the difference between one-piece and two-piece toilets?
Two-piece toilets are standard in old bathrooms. One-piece toilets are the latest technology in the market, but many people have started to embrace them. A two-piece toilet has the tank and bowl separate and adjoined during installation. On the other hand, one-piece toilets feature tanks and bowls that are integrated into one unit. Because of this, one-piece toilets are simple to install and clean.
Since one-piece toilets don’t have a gap between the tank and bowl, they are easy to clean and stay clean for longer. But with two-piece toilets, the coupling between the tank and bowl forms a breeding place for mold, mildew, and odor-causing bacteria.
When it comes to the replacement of parts, two-piece toilets are the best, as you can replace the tank or bowl when it cracks, but this is not the same for one-piece toilets. However, one-piece toilets look elegant and sleek, which makes them more appealing for modern bathrooms.
What is the importance of having a concealed trapway?
A toilet with a concealed trapway is very convenient as it makes cleaning easy. The concealed trapway, also referred to as the skirted design, hides the nooks and crannies that most standard toilets feature. These make cleaning cumbersome as they tend to hide dirt. Apart from that, a skirted style makes the toilet look beautiful and gives your toilet a modern appeal. That’s one of the reasons why people are embracing the skirted toilet.
