Size and Weight

A one-piece toilet takes up less space. But then, you don’t have much choice for toilet seat height. Often, the toilet bowl is 17 to 19 inches from the floor. That makes it comfortable for the knees and back. So, the elderly and people with mobility problems will find it ideal. However, a one-piece toilet is considerably heavier. Thus, moving it around won’t be that easy. A two-piece toilet is available in different bowl heights. Hence, you get them in both standard (15 inches) and comfort height (17 inches).

Verdict: Do you have less bathroom space or mobility issues? If so, go for a one-piece toilet. But for a portable one with more size options, go for a two-piece design.
