Initially, was happy with ordering and delivery time. Unfortunately, I was taken ill and had to store items (correctly on flat surface in dry conditions). Upon using the wall and floor tile backer boards 6mm, 10mm & 12mm, I can’t fault them. However, the 1200 x 900 x 30 wet room shower former was badly warped. Upon reporting this, it was suggested that I rest weights on it overnight. This does take the warp out for about 20 minutes only to return to the same state which renders it useless. Because of the time lapse, I was told there is no come back on replacement and would need to do so at full cost. Although I had initially checked the former for damage on delivery, I didn’t check it for warp damage. As I said, the multiple backer boards are all straight and stored the same. I would suggest upon delivery to check out not only if the items are in one piece but that they aren’t warped
