Twyford Option Close-Coupled WC (TWGGOT03WH) — White, 4/2.6L Dual Flush, European (Horizontal), Round, 360x630x770mm, Cistern + Seat

Vitreous china is fired at over 1,200°C until the clay body itself becomes glass-hard and non-porous — not just glazed on the surface, but vitrified all the way through. For a bathroom that sees daily use for decades, that's the difference between a bowl that still looks new and one that's visibly worn. Twyford picked up the Waterwise Marque back in 2007 for pioneering this dual-flush approach, well ahead of it becoming a standard bathroom expectation. A rating buyers can compare across brands is more useful than a manufacturer's own efficiency claim taken at face value. 360×630×770mm, white vitreous china, 4L/2.6L dual flush, European (Horizontal) outlet. Supplied as: Toilet Cistern, Toilet Seat. Round bowl, BS EN 997 tested. 25-year Twyford guarantee, Geberit Group. Imported to Nigeria.
