The answer to 'difference between toilet' is that there are several key differences between types of toilets, including flushing mechanism, water usage, and installation requirements. Gravity-fed toilets are the most common type, using a tank of water that is released to flush the bowl. Pressure-assisted toilets use compressed air to force water into the bowl for a more powerful flush, while tankless or flushometer toilets are connected directly to the water supply without a tank.
Toilets also vary in water usage, with standard models using around 1.6 gallons per flush (GPF) and high-efficiency models using 1.28 GPF or less. The type of toilet you choose will depend on your home's plumbing, water pressure, and personal preferences for features and performance.
