Installed the unit a few days ago. My 4 year old grandson and I use it. We live in Allentown PA and the faucet water is real cold. Dispensing Too close to the wall. Otherwise we like it and we will continue to use it. Still trying to figure out how much of the clear tube we should cut for best fit.

I have a "she-shop" and put this in my bathroom instead of a big bulky sink. This is fantastic. The water that flows through the faucet gives ample time to wash your hands and fill up a cup of water to keep on my desk to rise out my paint brushes when I'm doing my projects. The only downside is it does not fit exactly, that's why the four stars. It fits well enough for my purposes though. If there were children running in and out it might be a problem as they could bump it off. It's just me and an occasional visitor so it's fine.

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.

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!

The unit is easy to install and fits perfectly on my toilet. At first, the water flow for handwashing was so strong that it splashed the back wall. But I went back to the instructions and found that I had installed it without the flow diverter. The water flow with the diverter is prefect. It is just enough for hand washing and the length of time allows soaping up and a thorough rinse. And it looks great!
