If you’re trying to choose between and one- and two-piece toilet, there are a few factors to consider.

Q: I am a handy guy around the house and plan on replacing our old toilet. While searching for our perfect toilet I came across both one-piece and two-piece toilets that my wife and I like. My question is, are there advantages to choosing one toilet style over another?

A: A one-piece toilet is a single-component plumbing fixture, while a two-piece toilet has a separate tank and bowl. The good news is in most cases, both a one-piece and a two-piece toilet should fit existing plumbing connections.

If you’re looking to choose one type over another, there are a few factors to consider.

• The price for a two-piece toilet is usually less.

• A one-piece toilet has no gap between the tank and the bowl, so cleaning can be easier.

• If you’re installing the toilet yourself, it may be less stressful to carry and work with a two-piece toilet’s two smaller components, rather than a larger and heavier one-piece unit.

I hope I helped you flush out the differences between one- and two-piece toilets.
