5 weeks a go I ordered two vanity units including a sink on the top. They were fitted a week later. There are two cupboard doors under the sink. In less than 4 weeks they have split and blown. I contacted heat and plumb directly to ask if they could replace the doors with better quality ones, assuming that they were maybe a bad batch. They replied to tell me that at no point should any water come in contact with the doors. THE DOORS ARE FITTED DIRECTLY UNDER THE SINK. I had similar units from another company before these and the doors lasted over 5 years! Poor quality products. AVOID.
