Questions & Answers

What I don't understand is what you're saying. Regardless of the fact that hot water is involved, you know how this works. When they wash their hands, what do they use?

During my 3 years in Japan, I was stationed there. The apartment I stayed in over there had a toilet with one of those fancy heated toilet bidet seats, and the tank had a sink above it. It was just putting a soap dispenser or bar holder over the toilet and then, whenever you flush the toilet, waiting for the water to refill the toilet was what you did This method not only reduces your water bill but also conserves water to boot. As long as you live north of the Arctic Circle, the coldest water you will find is 55°F or less There is no reason to be hesitant about washing your hands at 65 degrees. There are special anti-sweat valves where the water is mixed with cold to prevent sweating in humid climates from cold water. You would install one of these valves if you were to plumb hot water to it. I don't like it! It is unlikely that even if you do make it to the water will cool before the next flush, there is a possibility that you will have a running toilet in the future and that hot water will melt the wax, so you will be very sorry you had to use the

This is provided by the prison guards, right? Is it a good idea to contact ?

Oh, my goodness! Not at all. There are no prison guards in this list.

Several controls are available. How can you turn them on and ?

When you flush the toilet, this feature is automatically turned on and off. The clean water in the pipes fills the toilet before the next flush. You can wash your hands before the next flush, when the soapy water fills the toilet.

There is already a handheld bidet connected to the toilet in our bathroom. ?

The hose connects to the valve directly. A tee-shaped joint is used to tie two water hoses together in normal water pressure. There are several videos on our Facebook site showing installations that people have done (sink twice) or (sink2x).

Selected User Reviews For Sink Twice for toilet tanks measuring 15.25" - 16.8" (measured with lid off)

I was pleasantly surprised at how well it turned out
5/5

In short, nbsp I chose this product because it was the cheapest one I found and it seems like a good deal. This is a good investment because I'm glad I took a chance on it. It was simple to install and the instructions were clear. This toilet was installed with high pressure, resulting in maximum efficiency. During flushing, you have ample time to wash your hands (see video) and the pouch fits over the toilet just fine. As a conversation piece for our guest bathroom, it has been an excellent choice. You can save a lot of water by doing this.

This sink is perfect for me
4/5

There is no way this will fit any of the three toilets I tested. There is no way I should have As soon as we figure out how to make it work, we'll do it. *Update 9/12
This company has the best customer service! Although this product won't fit my new toilet because it is older, the company's customer service was great. To eliminate the lip on the side of the ship, I ground it down. Now it fits perfectly. I love the way this sink looks and how it looks well built. My favorite thing about it is that it contains a soap dispenser. I'm really glad I did not return it now.

You can save a lot of water and your guests will have an interesting conversation with you I am so glad to see this! We save water, the kids think it's "fun," and it's not obviously a part of the landscaping
5/5

At least in my opinion, it is a price well worth paying, and it is made in the U. S. The people worried about grey water should just use this toilet with a toilet that gets regular use and it won't be an issue. You wouldn't be much affected by the soapy water anyway, except maybe after a long period of time you may develop a small soap scum line in the It's okay to drink from the toilet tank as long as you don't drink out of it!.

I really like it! Below is a detailed picture of this sink with its exact dimensions
5/5

My motive was to use this bathroom in the utility room where small children tend to play. My wife would prefer to use it for soaking clothes rather than for working in it, and my kids need a step stool etc. , etc. I put some water resistant double-sided tape on the sink to keep it clean. Two-sided 3M adhesive to semi-rigid Attach it permanently to the top of the toilet (in order to prevent curious kids from taking it off) and I even used the remainder to attach a soap dispenser. The first few days have been great! It would be great to see a detailed illustration of this sink, so that I could see the exact measurements above and below, and I am surprised the manufacturer doesn't do this for us. I would say that it is just right for the Delta Turner toilet tank, which is one of the smallest toilet tanks on the market. I bet you'll find this too small or will need the cosmetic extension kit (or will need to hem your own together) if you have a newer, nicer toilet. In addition to the Amazon warehouse fee, it is likely to cost less than $20 on this item. The company is making a killing, and I just wish they would package and present this product in a way that would make you feel good about helping them line their pockets. The kit has been made, etc. , but wouldn't it be nice if it also included the cosmetic extension kit for large toilet tanks, some better marketing/measurement materials, and a soap tray that could accommodate liquid soap. Just my opinion.

It's a brilliant idea
3/5

In itself, the sink is not very impressive. It's a brilliant idea. In itself, the sink is not very impressive. Despite its good looks, the material is very cheap to the touch. It would be much easier to do this yourself for much less money and get a much more attractive end product.

I was surprised by how much water is released each time you flush the toilet. I had to water my hands more than once. There is some weirdness about the way it sits on my toilet, and it isn't heavy enough to keep itself down, so I'll be looking for a solution. My favorite part is that they are constantly improving the product to make it better until it is good to be widely used!.

That's what I love about In my small bathroom, where there wasn't enough room for a sink, I chose this
5/5

Despite having no experience installing it, I managed to do so on my own. It has been criticized for being cheap plastic, but it is sturdy for its intended It would be nice if there were a way to attach it to the tank to make it more sturdy, however. Stabilizing this piece of clothing was achieved by using Velcro tabs on each side. Despite this, there would no longer be a problem if I didn't need to use.

A toilet tank of this size is too small for most Americans
4/5

One of the only reasons for having a 4 instead of 5 star rating is that it does not fit on the back of the tank very well. Despite its small size, it still works great. As a reason, I had to use duck tape to stop it from sliding back, it is still great.

Though not my first choice, I do not regret it
3/5

That sink is made of cheap plastic and I don't like it. Though I find it uncomfortable to use, my wife loves it and loves it so much that I have to share it with you. Whether the pipes can be repaired or not, I see it as an insult to plumbers everywhere, since it has allowed us to have a sink in a smaller bathroom once meant only for a The system annoys me because you have to wait for water to start flowing after the float drops in the tank. Once the toilet tank fills, you get a tiny stream of water that ends when the tank is full. It is your task to wash your hands under the tiny faucet before it shuts off, should you accept it. I also find it disconcerting seeing your hands' soapy water in the bowl of the toilet. Although this may sound silly, I am concerned that anything that goes down the sink drain will clog the wash holes on the You do not want to plug the tiny holes under the toilet rim, just think of how fun it would be to unplug them. If I could not unplug them, I would replace the toilet. This is why the sink has a strainer to prevent the disaster from happening. I would still not recommend brushing your teeth or anything else in this toy sink, aside from a quick hand wash. Spit or pour anything in this sink because, as long as it doesn't jam up the strainer, it is much better than if it jams up the holes for washing the rim. What would it be like to see tooth paste coming out of I hate it! Despite its potential for solving the problem of the missing sink when the bathroom is too small to accommodate one, this sink can only be used to a very limited extent. The best thing that you can do is install a real sink, but if you don't have the space, this toy can be a life saver, or at the very least a necessity.
