    So convenient and well-designed. Easy to install, no plumber needed. Great invention for any space, really.

      Thanks! The Caroma Dual Flush Toilets are very popular in the drought-stricken states right now, especially in California where you must have a water-efficient toilet to sell your home in many communities. Of course, the Profile Smart 305 adds the water and space saving sink as well.
