Structural classification
Toilets can be divided into two types: split toilets and one-piece toilets. Generally, split toilets take up more space, while one-piece toilets take up less space. In addition, the appearance of the split toilet should be more traditional and the price is relatively cheap, while the one-piece toilet should be novel and high-end, and the price is relatively high.
Outlet classification
The water outlet is divided into lower drainage, (also called bottom row) and horizontal drainage (also called rear row). The horizontal drain outlet is on the ground, and a piece of rubber hose should be connected to the rear outlet of the toilet when in use. The drain outlet of the bottom row, commonly known as the floor drain, just needs to align the drain outlet of the toilet with it when using it.
Classification of drainage methods
The way of pressing the toilet can be divided into "flush type" and "siphon type".
