Sink Twice for Toilet Tanks Measuring 15.25" - 16.8" (Measured with lid Off)

Perfect for my tiny bathroom! Easy to install and it works great. I’m just mad I waited so long to buy it.

When I put this in the tiny bathroom in back of house(no space for lavatory basin), the contractors thought it was crazy. But it has been great.( 8 mo in). The only thing is we had to glue it down so it’s on permanently or else it pulled away with ea wash.

Super awesome, I really like this thing for my basement one-third bathroom. Works as perfect as you'd expect. The one thing to improve, add a thin plastic wall to the back of the sink to act as a backsplash since most toilets are backed right up to a wall (and mine is paint). I mean it's only day one, but this functions so well I can't believe there aren't commonly available, cheapish toilets pre built like this already—toilets are only like $120 for dual flush models from a consumer priced box store, add a sink and really maximize bathroom efficiency.

My plumber installed a new Toto Drake 2 - 1.28 gpf elongated toilet and I purchased this Sink Twice topper because I've been wanting one for years. This was the first topper my plumber ever installed in 30 years of plumbing. I explained the mechanics, he looked at it, and installed it in less than a minute (but I screwed the faucet in place with a hex nut beforehand). It was easy even though the Toto toilets are a little different inside the toilet tank than Kohler and American Standard tanks. The included instructions were easy to follow and I'm positive I could have done it, though he was already there. Reviewers have complained about sturdiness, but it's a strong durable plastic. I got the specs for the toilet tank and checked it against the measurements for Sink Twice and it's great together. There's a bit more overhang on the depth which I allotted to the back of the tank), but a closer fit width-wise. The plumber advised that I add some adhesive so it wouldn't move around, but it hasn't been an issue for me. I have not jostled it at all. The water flow is good and I'm using the included flow regulator. I do splash the toilet lid at times (some drops, nothing huge), but I can't think of any alternative design that would really reduce the splash anymore. My toilet is 1.28 gpf and this is plenty of water to wash your hands. If every household in California had this, it could make a difference in reducing our water usage. Obviously, it's impact is not as great as commercial/agricultural interests, but it really does the trick as a closed loop system here for you eco-minded folks. I also considered a manual bidet with this system and didn't move forward with it, but from what I've read, it works in concert together as well. Have fun with your new Sink Twice!

I really don't like this cheap plastic sink. It makes my skin crawl using it, but my wife loves it and is so happy we got it. I see it as an insult to plumbers everywhere while it has allowed us to have a sink in a closet size bathroom bathroom that is barely big enough for the toilet. It annoys me to have to wait for the water to start once the float drops in the tank and then you get a tiny stream of cold water than ends once the toilet tank is filled. Your mission, sould you choose to accept it, is to wash your hands under the tiny faucet before it shuts off. It is also disconcerting to see the soapy water from your hands going into the toilet bowl. I know this sounds silly, but it bothers me because anything that goes down the sink drain may plug the wash holes in the toilet rim. Trust me, you don't want to plug the little holes under the toilet rim, just thing of how much fun it would be trying to unplug them, I would replace the toilet if I couldn't get very lucky with a piece of wire. This is why the sink has a strainer to try and prevent that disaster from happening, at least they thought of that. But I would still not recommend brushing your teeth or much of anything else other than a simple hand wash in this toy sink. Anything you spit or pour in this toy sink may clog the strainer which is far better than if it clogs the rim wash holes. Can you even imagine tooth paste coming out the rim wash holes? Yeech! While this sink can solve the missing sink problem in a bathroom too small to install one it, it is a very limited aplication minture plastic sink. If you have room, get a real sink installed, but if you don't, this toy can be a life saver, or at least a bathroom saver.
