What is a Sink Built Into The Toilet?

A sink built into toilet, or a toilet with sink on top, is an innovative way to save water, money and space while protecting the environment and promoting hygiene. That sink is built into the toilet tank, and you can easily convert your existing toilet into a toilet-sink combo or purchase a complete unit at most home improvement stores.

How Does a Toilet Tank Sink Work?

A toilet sink is a device that uses gravity to conserve water. When the sink is used for hand washing, gravity carries the water into the toilet tank for the next use. Each flush saves several gallons of water, which can add up over time.
The sink itself is installed on top of the toilet tank. When you wash your hands, the used soapy water flows through a small tube that is connected to the toilet’s water supply and fills the tank for the next flush. This process means you flush the toilet with gray water that you already use to wash your hands instead of drinking water.
Today, more than ever, water is a precious resource. Toilet sinks allow you to make the most of the water you’re already using. Older toilets can use up to 5 gallons of water in a single flush! By installing a toilet sink, you can significantly reduce your water usage. Not to mention, the less water you use, the more money you’ll save on your home’s utility bills. Win-win!

Benefits of Owning a Toilet Sink

● It saves water and money. The most important benefit of a toilet-sink combination is water retention. Instead of using different water for rinsing and washing hands, you can cut your water use in half.
The same amount of water serves two purposes at once – you can wash your hands and use gray water to empty your toilet. Most toilets use 1.28 gallons per flush, but you don’t have to double the amount by using fresh water twice.
Owning a toilet sink is a simple, affordable way to move closer to a sustainable home, which benefits the environment and your wallet. The toilet sink’s efficiency and ability to reuse gray water allow for less wasted clean water, which means more money in your pocket.
● It saves space. A cute toilet-sink combo saves space in the bathroom. This is a compact unit, so no additional space is required to install it.
The logic is clear – you have to put a toilet in the bathroom, but you don’t need to take up extra space for a sink.
● Improves Hygiene. Many people don’t always wash their hands after using the toilet. It’s an embarrassing habit, but a toilet and sink combo can help you get rid of it.
It’s easy to see why – the device actually forces users to wash their hands after flushing the toilet. This sink and toilet combination automatically turns on the water to remind users of the need to wash their hands.
