Lifetime warranty is worthless
They say Caesarstone has a lifetime warranty until something goes wrong. No warranty at all, just excuses that it is not a factory fault. We had two benchtops installed at the same time in each bathroom. Sent this message to them after their technician came out to assess but have had NO response. - The vanity in question is located in a bathroom that is rarely used. We do not use harsh or caustic cleaning products on any of our Caesarstone surfaces — only mild household cleaners as recommended. There has been no plastic wrap left on the surface, nor have any chemical products been stored on it for extended periods.
What concerns us most is that we have two Caesarstone benchtops installed at the same time, under the same conditions, and only one has developed these brown marks — and they continue to spread. If this were caused by user-related damage, we would reasonably expect similar wear or marks on the other vanity top, which has not occurred.
We are careful homeowners and have taken every precaution to care for these surfaces in accordance with Caesarstone’s guidelines. The marks appeared without any identifiable incident and have progressively worsened. Given these circumstances, we believe this warrants further investigation as a potential material issue rather than external damage.
We would appreciate:
1. A secondary review of the claim, preferably by a senior technician or independent assessor.
2. Written clarification outlining specifically how the conclusion of “caustic burn” was determined.
3. Confirmation of whether similar cases have been reported with this product batch.
We chose Caesarstone based on its reputation for durability and its lifetime warranty, and we are hopeful this matter can be resolved fairly.
