A toilet is a sanitation hardware used to collect human waste. Toilets can either be with or without water but it wasn’t until the 3rd millennium BC that the first-known urban sanitation system in the world came into existence, thanks to the Indus Valley Civilization. It was during this time that toilets and sewers were invented and flowing water was used to remove human waste.
The modern flush toilets, on the other hand, weren’t invented until the year 1596 by Sir John Harington. Harington’s design had a flush valve to let water out of the tank with a wash down design to facilitate the cleaning of the bowl. Over the years, the toilet has seen many technological advances to shape it into how we know it now.
Toilets can be one-piece or two-piece units. One-piece units are visually sleeker since there are no gaps between the bowl and tank. These are also easier to clean because of the absence of grooves and spaces. One-piece toilets are more expensive compared to two-piece units but the probability of leakage problems is also reduced significantly.
Two-piece toilets are easier to move and carry around since the parts are detached from each other but installation also takes longer since the bowl and tank need to be connected to each other. Two-piece toilets are cheaper compared to one-piece units and have more options when it comes to height and style. However, these are also harder to clean since dirt can get into the spaces and are more likely to leak.
