Back in a January post, we took leading-edge Australian toilet manufacturer Caroma to task for the design of its Profile Smart high-efficiency toilet that incorporates a sink into the lid of the toilet tank. We’re fans of the idea but not the execution. As far as reviews go, it was a mild thrashing. We simply called the idea “unresolved,” if I remember correctly. At any rate, the post was written out of love since we are fans of the company that brought us the dual-flush toilet. And to prove its awesomeness, the company has launched its One Flush Promotion in honor of the upcoming Earth Month. Under the deal, you get 50 percent off the list price on qualifying products, including toilets, sinks, and accessories. The promotion ends June 30, 2011. Now that is a fully resolved idea. ww.caromausa.com.
