Caroma Makes A Toilet With Sink Look Elegant
We have been showing toilets with sinks built into the lids of the tanks for years, including home-made and aftermarket plastic versions. Now Caroma gives us a dual flush toilet that they claim will save a family of four 30,000 gallons of water per year over an older toilet.
The dual flush controls are detailed neatly into the lid. More at Caroma
