Frequently Asked Questions
Often, when a beginner starts to take an interest in one-piece toilets for buying, there are some questions that bother them more than the others.
Let’s see and answer some of them:
What is the difference in a one-piece and two-piece toilet?
Two-pieces toilets are the regular ones that are installed in most homes; however, one-piece toilets are quite rare and offer a joined design of tank and bowl.

Again, this is quite a specific question and highly depends upon the model we’re talking about.
