Western toilets and eastern toilets differ in design and functionality. Western toilets are typically raised off the ground and have a seat for sitting, while eastern toilets are often squat toilets that are closer to the ground. Western toilets use a flushing mechanism to remove waste, while eastern toilets may require manual flushing or use a different method for waste removal. Additionally, western toilets are often equipped with toilet paper, while eastern toilets may use water for cleaning.

Salt water is not used in toilets because it can cause corrosion and damage to the plumbing system. Additionally, salt water is not as effective in breaking down waste compared to fresh water.
Toilets with a 1.28 gpf flushing capacity use less water per flush compared to toilets with a 1.6 gpf capacity. This means that toilets with a 1.28 gpf rating are more water-efficient and can help save on water usage and utility bills over time.
Composting toilets are considered "dry" toilets which use decomposition to eliminate waste as opposed to high pressured water. Further information about these toilets can be found on the Envirolet website.
