Sinkology SinkPositive GreenFlow Toilet Tank Sink

I got this product because I was looking for a new toilet with a built in hand sink and discovered you can't actually buy them in the US because ... because America I guess. What an absolute no brainer to wash your hands in the clean water coming in from the street, and THEN use that gray water to flush.This is not complicated to set up and it's easy to fix if you accidentally bump the lid or something and one of the pipes pops out of place. Of course I wish it weren't plastic but it does make the sink easy to move, adjust and clean. I do use a gentle foaming hand soap with this; haven't noticed any build up or other issues though it's only been a couple of months.Clever, practical, easy to install, and amazing way to reduce water waste and city sewer costs!

The media could not be loaded. It works! Because the bathroom situation in my old house is more of a toilet stall than an actual toilet/bath room, there just was no room to put in hand washing sink. I looked at various prebuilt sink/toilet combo units online but alas, they were very expensive to ship to and install in the US so I looked at convert tank lid sinks instead. Easy options were limited to just two, this sink and another on Amazon, and went with this option because I liked how simple this one looked overall. I decided to spray paint the sink first to match the dark green toilet seat I'd picked out, and I'm pleased with how it looks and functions overall. The sink literally just sits on top of the tank edges, it doesn't fit fully around a standard tank, so hypothetically it's easy to bump off if you're not careful moving around it. It also doesn't completely drain no matter how I tilt it, there's always a quarter size puddle not quite near the drain hole but ultimately it doesn't bother me. I also put wax sealant around the base of the facet connecting to the sink to plug water leaking out. Easy to adjust the water flow so that it drains right into the drain hole with less water back splash, but recommend putting up a wall backsplash anyway since the sink depth is still quite shallow so water does inevitably splash out a bit. My flush flow runs quite long (almost 2 mins) so plenty of time to wash hands on a single flush. It's great for what it is, and for the price would 10/10 recommend

hose is to stiff and wrong size to fit on standard ball cock valves.The stiffness of the hose causes it to collapse when you try to attach it.for the price the unit is very flimsy.

Eh. It's cheap plastic, janky fit, and works technically.3 stars it's better than not washing your hands after a dookey.

Product was easy to install and works fine. I was a bit disappointed in that it was more "light weight" and thinner material than I expected. Reason for the 1 star deduction. I expected a bit heavier product in regards to material for the price.

The media could not be loaded. Needed to come up with a solution for putting a sink into a half bathroom, after taking existing vanity sink out and replacing with washer dryer stack. It’s made out of plastic that seems cheap but is fairly sturdy. It fit onto glacier bay toilet with slightly curved tank front. Hooking it up was fairly easy, had to force the metal drain nipple to pop into place. I also had to cut the drain tube to a shorter length and I used existing water fill hose instead of the one it comes with, which was too big a diameter for the flush valve. It runs for a longer time and some water splashing over is expected. It’s a temporary fix until I can get a corner sink installed or order a true sink integrated toilet tank from Japan.

Muy pequeño, no es muy práctico, el agua se riega al usarlo y moja toda la superficie.Esperaba algo mejor pero no hay caso ya se instaló y no me gusta esta solución

Wish I had known about this years ago. Makes a small bathroom space more efficient! Super easy install
