What is not covered by the MERLYN Lifetime Guarantee?

The Lifetime Guarantee does not cover damage caused by wilful damage, neglect, misuse, accidental breakage, or fair wear and tear. It also does not cover breakage of or damage to the glass or its coating unless the defect was present at time of purchase, and it excludes showering items (such as valves and shower heads) and items not part of the shower enclosure (including separately purchased shower trays and similar items).
