Ergonomic Ceramic Zinc Flush Lever

Ceramic handle length: 10 cm. Zinc lever arm length: 10.5 cm. Total operational length: 15 cm. Width: 1.8 cm. Constructed from vitrified white ceramic and chrome-plated ZAMAK-3 zinc alloy. Includes transparent silicone gasket and white polypropylene retaining nut. Designed specifically for UK domestic bathroom conditions—humidity, hard water, and frequent use. The ergonomic curvature follows ISO 11227 guidelines for hand-operated controls: radius of grip zone matches average adult thumb-index finger span (6.2–7.1 cm), reducing joint strain during actuation. Chrome plating thickness ≥0.25 µm ensures longevity in high-humidity environments. Ceramic glaze hardness ≥6 Mohs resists daily abrasion from towels or cleaning cloths. Installs directly onto existing UK cisterns without drilling or adaptors. Compatible with single-flush, dual-flush, and push-button conversion kits. The white finish reflects light efficiently—improving visibility in low-light bathrooms, a practical benefit noted in Age UK accessibility guidance.
