Benefits and Uses of Two-Piece Toilets
Suitable for Adults and Tall People
A two-piece toilet is larger than a one-piece toilet. It would require more footage in the bathroom as compared to a
one-piece toilet, but it has the added advantage that it can be more convenient to use by adults as well as tall people. The height of the two-piece toilet is higher as compared to the one-piece ones. However, it is a moderate height, and this also helps tall people and adults use it more conveniently. The one-piece toilets are more suitable for the disabled and the kids.
Cleaning and Maintenance

Replacement of the Damaged Portion
With a two-piece toilet, if the flush tank part of the toilet is damaged or out of order, only that part would need to be changed. In the case of the one-piece toilet, if one part of the toilet is damaged beyond repair, the entire one-piece toilet would need to be changed. This becomes a financial burden as the one-piece toilets are more expensive as compared to two-piece ones. As such, the two-piece toilets are not just better in terms of affordability; they are also beneficial when only one part of the two-piece toilet gets damaged and needs to be replaced.
Installation
Many people install toilets themselves and do not call a plumber or outside help. The user, however, needs to follow instructions properly and needs to know the rough-in. The one-piece toilets are harder to install as compared to two-piece ones. As two-piece toilets come in 2 separate parts, it is easy to install this one by one after following instructions. The one-piece ones, on the other hand, are hard to handle by one person as they ate heavy. As such, the two-piece toilets carry an advantage in terms of ease of installation.
Affordability

As such, the two-piece toilets are cheaper and more people purchase these due to their affordability.

This is not possible in the case of the one-piece toilets in which case, only one type, color, or design can be bought.

The two-piece toilets allow the user to act as decorators while choosing the two parts of the two-piece toilet.
Shipping
The two-piece toilet is easier to ship as compared to the one-piece ones. The two pieces are shipped in 2 separate boxes which are easy to handle during transportation. The single box of the one-piece toilet would be quite big, and thus, it would be harder to handle and take care of. This could also be quite disturbing if the toilet cracks n the way. In the case of the one-piece toilet, all of it would need to be changed while in the case of the two-piece toilet, only one piece would be damaged and changed.
