If you want something really unique in your bathroom then you should take a look at the Ammonite washbasin from HighTech that is shaped as a fossil. This unique design showcases the organic qualities of concrete. The washbasin can be produced in widths between 90 cm and 330 cm with a standard depth of 56 cm, and is available in several colors. It can be installed either with a table-mounted or wall-mounted tap. Now the design might be unique and cool, but if you would like to wash something it will be quite hard, and the cleaning part will also be a challenge. – Via – Thanks for suggestion Mike
