Saving Water with the Toilet Sink Combo

SinkPositive is a toilet accessory that retrofits nearly any existing toilet into a toilet-sink combo unit. Installed in just minutes, without special tools or a plumber, this combination unit can save the water you would otherwise use to wash your hands by using the same water to both wash with and flush with.


The fact of the matter is that your toilet, as it now sits, uses perfectly clean water to flush with. This water is as sanitary as the water coming out of the sink. The benefits of this combination unit are plenty and prove, as units like these are being widely used in Japan.

Its system is simple, when the toilet is flushed the water pumps up through the pipe to the sink, automatically turning the sink on and drains down to the bowl. The sink will turn off automatically.

• The same water is used for flushing and washing allowing you to save water - helping the environment.
• In parts of the world where water is scarce, using the same water for flushing and washing encourages hand washing which is overlooked so the water can be used for something else.
• A tiny bathroom that only has a toilet can now have a toilet and a sink!
• You just might save a few pennies on your water bill.
• The sink turns itself reminding the user to wash their hands (especially good for children)
• Because it turns off when the toilet no longer needs it on, a water leak in the system is easily detected (when the sink runs and runs)
• Because the sink turns itself on and off, there is no need to touch the knobs which are often covered in germs, and also difficult for people with arthritis or other physical conditions.
• Homes with well water can save water as well as the electricity needed to pump it.
