Space Saving Toilet

sink toilet

If you asked me a year ago if I would ever be blogging about toilets, well I most likely would have laughed at you.

I have seen these before, but they are most often conversion kits and a never looked quite as nice.  The Caroma Profile Smart is a Small profile toilet that has an integrated sink that uses the water before it goes into the toilet.  I have told folks about these before and often get this disgusted look, if you have never had to fix one you might not know how they work.  First the water fills a reservoir tank, that tank empties down into the bow through small holes at the top, the water collects in the bowl and well you know the rest.   The water that goes into the reservoir is 100% clean water, same stuff you drink from the tap.

If you are in another country this may not be the case as they sometimes use grey water, which I hope catches on here, but here in the US of A we use the regular water to fill the bowl.  What is more many folks put what are essentially chlorine tablets in the reservoir which creates a barrier if you will.  In fact if you read any disaster preparedness guide they talk about if push comes to shove, you can drink from the reservoir (best to boil).

So what’s so great about this toilet first it actually looks somewhat attractive, the second is that it is a very narrow profile, perfect for tiny houses.

  1. These are common in Japan and have been for many years.

  2. Yes, I have been looking for an American equivalent for some time now. Awesome find!

    • I have also seen conversion kit, I haven't seen them in the stores recently, but wasn't looking for them either.

  3. My name’s Lizzie and I go to Tiffin Girls’ School in London. I found this toilet picture using google and would like to use it in my school project about space-saving furniture. Do I have permission to use it? Thanks

  4. It seems from product info that it is only cold water – I could see that being a problem in cold water, do people ever hook it up to warm water?

  5. Sorry, I meant “cold weather”

  6. This a great idea, have you any idea where in the UK these are available?

  7. Où puis-je trouver en France ce type de WC avec lave-mains ?

  8. Great Idea. Innovative and thought provoking. If we can do this to toilets, what other utilitarian objects can we make smaller?

  9. Where can I purchase one of these for US Delivery

    • This site has several different models of the Profile Smart Toilet Available.

  10. These toilets have really taken off in recent years due to the tiny house boom. There is a great website that has these Profile Smart Toilets for Sale.
