I bought a bunch of new bathroom stuff from a supplier recently, total cost was around £3K as part of a larger renovation project on 2 bathrooms and a downstairs WC. Things were mostly fine, but the sink and basin unit for the en-suite wasn't what I expected. I was expecting the sink to be a standard porcelain/ceramic finish, but it turned out that it was poly marble, which is an acrylic material. By the time I noticed this, it had been installed by the fitters. I had 3 bathrooms to do and a ton of boxes so couldn't realistically check it all over like I would have done normally. I have raised a dispute with the supplier because the manufacturers website that advertises the product does not make the material finish clear. I would expect to see the key facts under the Specification section, but it doesn't list it. Manufacturers link: https://www.hudsonreed.co.uk/products/furniture/fusion-fitted-furniture/gloss white/CBI141 The price I paid was around £160. Supplier says that as the item can't be returned with original packaging they won't refund it. I've tried to get them to talk to the manufacturer but they don't seem to be entertaining that anything is wrong. I've put in a paypal dispute but the supplier has stated that if that succeeds, they would try and get back the money from me via small claims court. The sink needs to be written off, but should it be me that does so? I could have looked deeper into the specs but I just assumed it was a normal sink, and the manufacturer could definitely make it clearer on their website.
