This Low-Flow, Dual Flush Toilet Uses Water From Washing Your Hands For Its Next Flush

Switching to low-flow fixtures and utilizing "greywater" are two of the biggest ways to save water at home...but let's face it, both are SO inconvenient! But the Profile Smart dual flush toilet from Caroma is here to change that.

Here are the specs:

  • High efficiency dual flush toilet - 1.28/0.8 gallons (4.8/3 liters) per flush
  • Integrated sink for enhanced water savings
  • After flushing, fresh cold water is directed through the faucet for hand washing and drains into the tank to be used for the next flush
  • Unique water and space saving design
  • Chrome buttons built-in to tapware design
  • Easy installation
  • Large trapway virtually eliminates blockages

Even though this toilet is super low-flow, it's trapway is large enough to allow limes and potatoes to pass through. And let's face it, if you're dropping potato-sized nastiness in this bad boy, you probably need to hydrate better or work more fiber into your diet.

Here's a demonstration of the potato and lime flushing action on The Today Show:

Another factor that makes this toilet so great is that it reuses the nearly clean water that you used to wash your hands in the next flush of the toilet. That's an incredibly simple, easy, and efficient greywater system! What's even better is that it doesn't involve the installation of an expensive and complicated greywater system, but is much more sophisticated than simply catching drain water in a bucket and filling your toilet tank with it.

Would you outfit your bathrooms with this lean, mean, porcelain machine?

    I probably wouldn't want a toilet like this in my home (just because esthetically, not exactly overly appealing), but this would be amazing in a place with limited space and septic capabilities such as a camp on a lake.

    I love the idea, but it looks a little hard to wash your hands... either next to the sink or straddling the toilet? Also... you would have to be careful not to brush your not to drop your toothbrush in the toilet!

    I live in Japan at the moment and have one of these green machines in our smaller upstairs bathroom. First here in Japan they separate the toilets from the bathroom which is pretty great since how many times have you had to go but a spouse or child been in the shower, etc. Also the sink can be very esthetically I have had friends add rocks to sink to a a rock garden feel. The space is a little smaller then usual for a sink but with a little effort it works very well and I say this because I have small children who started using this when they were 3 and 5 years old. I have lived in places in the U.S. where the bathroom was so small your knees touched the sink so this would have been much nicer!

    I would definitely add this dual flush toilet to my outdoor pool/barbecue bathroom. Kaitlin Jaffe, this sink is for washing hands after you flush; it's not intended for brushing your teeth, so you don't need to worry about your toothbrush falling in the toilet.

    @Patricia El-Kareh, If one was thinking about installing this toilet in a residential bathroom they would also need another sink to brush your teeth at? Seems inefficient not to catch all the wastewater you can in the bathroom to flush with.

    one could design a bigger sink next to the toilet, with the drain leading to the water hopper thing- that would eliminate the standing on or straddling the toilet to wash one's hands

    I think Lucky is right the point more is about the concept of grabbing the waste water for use.

    This is a cool looking design though I wonder how well it works!

    Hey I used to use the exactly same thing...When I was in prison. Only mine was a much nicer stainless steel version. Easier to get the blood off that way I suppose. .
