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.

We had a small closet on the pool deck with enough space for a toilet but not much left over for a sink. The unit did not fit our toilet quite perfectly but ran a caulk bead around the inner edge and it has stayed in placed for a year now. It's amazing to not have to walk through the house wet from the pool to use the RR and this item made that possible. The wife was not going to a toilet go in unless guests could wash their hands and we had some crazy ideas until we stumbled across this.

This is an excellent product but when you wash your hands, the sink is not wide enough and the water spills over onto the floor. But since I am using this product at my business office, it is ok but I would not use it at home because of the water spilling on the floor.

This was a replacement of one I had purchased years before. Pretty sure it was by the same company just a newer model and it’s much better than the first one that I purchased. Aesthetically it is more pleasing too. Easy to install and put together. I bought some putty to go around the interior edge so that it stays nice and snug where it belongs and I think that was the key for a good solid fit.

Shown with matching soap dispenser. Product instructions show matching soap dispenser. There is NO soap dispenser of any kind. So, immediately you do not get everything you thought you paid for.Product is made out of plastic. To be fair, it seems to be very strong plastic. It seems to be engineered well. I had to buy additional product for it to fit my tank. All in all, it is overpriced for what you get (don't get). Nonetheless, it does present a solution for a 1/4 bathroom with no sink to wash your hands.

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!

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.

**Warning: Do NOT Buy SinkTwice!**I cannot stress this enough: steer clear of the SinkTwice at all costs! This so-called innovative product promises to help you reuse toilet water to wash your hands before it enters the tank, but let me tell you, it's a disaster waiting to happen.First off, the design is a joke. Made out of flimsy, cheap plastic, it feels like it's going to fall apart in your hands the moment you touch it. But wait, it gets worse. Within days of installing this monstrosity, it started leaking onto my precious wooden floor boards.And the damage? Irreversible. My once pristine floor now looks like it survived a flood, all thanks to the incompetence of the SinkTwice. Don't believe me? Check out the attached pictures if you dare.And if you thought the leaking was the worst part, think again. The SinkTwice doesn't just fail at containing water; it also fails miserably at draining it properly. Instead of efficiently channeling water away, it creates a cesspool of disgusting soap scum and germs that cling to its cheap plastic surface.Imagine reaching for this supposed handwashing savior, only to recoil in horror at the sight of grimy, slimy residue coating its every inch. Not only is it a breeding ground for bacteria, but it's also a nightmare to clean. No amount of scrubbing can rid it of the foul stench and unsightly buildup that accumulates with each use.So not only does the SinkTwice ruin your floors, but it also puts your hygiene at risk with its inability to maintain basic cleanliness standards. Do yourself a favor and spare yourself the ordeal of dealing with this germ-infested disaster waiting to happen.Save yourself the headache, the expense, and the heartache of dealing with water damage. Avoid the SinkTwice like the plague. It's a disaster waiting to happen, and you'll regret it the moment you bring it into your home.
