One-Piece Toilet vs Two-Piece

1 piece vs. 2 piece toilet comparison

When buying a toilet, consider the type of configuration you want and need. For example, would you like an elongated toilet or a round-front? Should you go with a standard 12″ rough-in, or do you need a different size because of space constraints? Although not the most important consideration, it’s worth considering one-piece toilets vs two-piece toilets. There are a few reasons why you might regret the wrong decision.

Why Do I Need to Know My Toilet’s Configuration?

Knowing whether your toilet is a 1-piece or 2-piece design is important for several reasons, especially when it comes to repairs, replacements, or upgrades. The two styles have different construction: a 1-piece toilet has the tank and bowl fused together, offering a sleeker look and fewer crevices for dirt to accumulate, while a 2-piece toilet has a separate tank and bowl, which can make certain repairs or replacements easier and more affordable.

Additionally, seat sizes, flush mechanisms, and installation requirements can vary between the two types, so identifying which style you have ensures you purchase compatible parts and follow the right procedures.

Comparing a One-Piece Toilet vs Two-Piece

Toilets consist of three main parts: the pedestal, the bowl, and the tank. With one-piece toilets, all 3 pieces come in one complete unit. With two-piece toilets, the pedestal and bowl are separate components, while the tank is a distinct unit.
