Firing a toilet pan to full vitrification closes every pore in the ceramic body, which is what keeps a bowl looking new years after a lower-fired one would show staining. That measured absorption standard is what separates genuine vitreous china from ceramic that only looks similar on the shelf. A European Water Label rating accompanies Flushwise cisterns, giving buyers a standardised efficiency figure to compare against other brands' dual-flush systems. It's the standard now expected on any project targeting current water-efficiency regulations. 455×625×775mm, white vitreous china, 4L/2.6L dual flush, European (Horizontal) outlet.
