"I am a plumber, and an experienced DIYer, but this shower surround was an absolute swine to install. When I realised that it was going to be awkward, I had already gone some way into the installation, and couldn't return the item. Two people would have made it a bit easier handling the 'L' shaped screen into position in one piece. Here are just a few points... 1) The majority of people in this country can read English. Installation diagrams should be used to clarify the words, not replace them. 2) The authors of the instruction book should try to install the surround using their own instructions in the given order! 3) The pre-drilled screw holes were too small. 4) Extremely fiddly to get the door slider blocks adjusted correctly, and tight enough. 5) Hex headed screws would have been better for adjusting the sliders. 6) No mention of the door seal fitment, and I had gone past the point when they would have been easier to fit - so had to undo some work. 7) Plastic caps would not stay on the screw heads. The whole set-up was infuriating to say the least! But now it is in, it does look ok..... but never again with this one."
