Questions & Answers
Where does the water come from
Hello! The fresh water line input for the toilet connects to the sink faucet. When the toilet is flushed the water is sent to the faucet and the sink drain fills the toilet bowl. It shuts off when the bowl is full. If you have any additional questions, we'd be happy to help! Reach out to our customer service team at customerservice@sinkology.com
Can I brush my teeth in an over the toilet sink?
Yes, absolutely! The water feeding it is the same as what comes out any other sink, and what you spit out will just flush away.

Can I change the faucet or so I have to use the one that comes with the sink
Hello! The faucet that comes with the sink is built into the sink, so it would not be able to be changed. Let us know if you have any additional questions!
Why are there so many wrong answers to the questions, especially from the "TEAM"? This product is not Code compliant as a bathroom sink. The water that flows from the fill valve (ballcock) does not enter the tank. It goes down the overflow to the bowl.

If there's anything we can help you with regarding the SinkPositive GreenFlow Toilet Tank we'd be happy to help! Please reach out to our customer service team at customerservice@sinkology.com
Is this compatible with a Glacier Bay power flush single flush toilet?
Hello! The best thing about the SinkPositive GreenFlow Toilet Tank Sink is that the length of the sink is adjustable and can fit many different brands of toilet tanks. The specifications for this sink are: an adjustable length (side to side) of 16.5” - 22.5”, width of (front to back) 8”, and height of 9.25”. We would recommend determining the size of the toilet tank that you have or desire to have and go from there!
Will this fit on a 8x16 tank
Hello! The length of the SinkPositive Toilet Tank Sink is adjustable from 16.5" to 22.5". This sink may be slightly bigger than your tank - it should fit, but there's a chance it may move minimally from side to side with the extra half an inch. The width should fit perfectly as the width of the sink is 8".
Does this work on Toto toilets?
Hello! Thank you for reaching out! The GreenFlow Toilet Tank Sink is adjustable in length and can fit a toilet tank that is 16.5" long to 22.5" long.
