💦 Sink Twice: Efficient Toilet Tank Addition (15.25"-16.8" Measured with Lid Off) Review

Tried on three different toilets, none fit. I regret the purchase. I need it, so we're going to do something to make it work. Update 9/12 This company has the best customer service! My toilets are old so this product doesn't fit as well as a new toilet. I was told to sand down the lip on the sides and now it fits perfectly. This sink is well made and looks great. I like that there is a place for soap. That's why I didn't send it back. Now I'm very glad I didn't send it back.

The concept is awesome. The sink itself is mediocre. The material looks and feels very cheap. You can do it yourself for a lot less money and get a much prettier end product. I was surprised how much water you get with each flush, more than enough for each hand wash. It sits oddly on my toilet and isn't heavy enough to hold itself in place, so I'll look for a solution to this problem. I love this idea and hope they keep improving the product until it's good enough. Main power!

That's great! It saves water, kids think it's "fun" and looks pretty out of place. It's worth the price, at least in my opinion, and it's made in the USA. For people worried about gray water, just use this with a regularly used toilet and it won't be a problem. Soapy water isn't going to be much of a problem anyway, except that after a long enough time you might end up with a small line of suds in your aquarium. Just don't drink from the toilet bowl and you'll be fine!

I bought this for a bathroom in a utility room used primarily by young children. We have a huge general purpose sink but my wife would rather use it to soak clothes and the kids need a stool etc etc. I used 3M waterproof double sided adhesive to semi-permanently attach it to the top of the sink. Toilet (to discourage curious kids from taking it off) and I used some extra to add an automatic soap dispenser to the top. So far, so good!

This product is theoretically amazing and I've been using it for over a year with no problems. Until I had to look in the toilet's water tank the other day, I noticed that the entire right side of the basin (where the sink drain is) was covered in black mold. Not a few spots, but it was so even that I thought it was a shadow for several months. How could I have overlooked this for so long you ask? Well, the design of this beautiful product does not allow you to lift the top to inspect it…

I really don't like that cheap plastic sink. It gives me goosebumps but my wife loves it and is very glad we bought it. I see that as an insult to plumbers everywhere while it allowed us to have a cabinet sized sink that barely fits in a toilet. It annoys me to have to wait for the water to start flowing once the float falls into the cistern, and then there's a tiny jet of cold water that spills out once the toilet cistern is full. Your mission, should you choose to do so, is to wash your hands

I said it would reduce water usage. I say it like that because I don't know if it will save you money. If you're paying rent, your water is probably included. But money is not the most important thing. We must preserve our resources if we hope to share them. This will help you with that. Not paying rent helps you save money. I'm not a plumber but I was able to install it myself. The manufacturer is very helpful and was able and willing to answer some of my questions. For example, the…
