Toilet Types Explained: One Piece vs. Two Piece

In the market for a new toilet? One of the first decisions you'll face is whether to go with a one piece or a two piece model. Let’s break down what each type is and how they compare.

One Piece Toilet vs. Two Piece Toilet: What’s the Difference?

One Piece Toilet: In one piece toilets, the tank and bowl are fused together into a single, seamless unit. These toilets tend to have a sleek, modern appearance and are typically easier to clean because there are fewer crevices where grime can build up.

Two Piece Toilet: As the name suggests, two piece toilets have separate tanks and bowls that are bolted together during installation. This is the most common type found in homes and businesses and offers more variety in size and style.

Key Differences

Cost: Two piece toilets are generally more affordable than one piece models. If you're working within a budget, a two piece toilet bowl and tank may be the better choice.

Durability: One piece toilets tend to be more durable because there’s no risk of a tank-to-bowl connection leaking or loosening over time.

Size: A one piece toilet is often more compact, making it ideal for small bathrooms. Two piece toilets may offer more flexibility in height and bowl shape options.

Appearance: One piece toilets offer a streamlined look and are often favored in modern designs. Two piece toilets have a more traditional feel.

Installation: Two piece toilet bowls and tanks are lighter and easier to move, which can make installation simpler in tight spaces. One piece toilets are heavier but require fewer installation steps since there’s no need to connect a tank to a bowl.

Maintenance & Repairs: Two piece toilets are easier (and usually cheaper) to repair if something goes wrong with the tank or bowl, since the parts are separate. One piece toilets may require replacing the entire unit if a major component fails.
