purchased Nuie mdf water resistant gloss white side and end panels and received within 3 days of ordering.Installed 5 days later and within 2 days the upper edge of end panel where it abuts to bath tub lip as blown. Silicone sealant was forced into all joints with only the manufactured edges showing so water cannot enter to back of panel which is not vinyl wrapped, No problem,it as a 5 year warranty contacted Heat and plumb and reply I got back is the problem is caused by water ingress. What load of rubbish its total garbage cheap and nasty, I had previous panels from bathPanelStore and they where perfect after 12 years and installed identically ,only replaced as new bath as been installed and they where to short to fit. DO NOT BUY THESE NUIE PANELS YOU WILL REGRET IT
