An update ...
Bathroom is now fully-installed (no thanks to Wickes i might add).
However, Wickes gave us a full refund & compensation & left the bath, sink, cupboard, WC and vanity units. Took a guy recommended to us by a friend just over day to sort everything out.
Ref posts #2, #50, #58 - the bath legs weren't put in the correct place - when they were fitted into the correct place, the legs didn't foul the pipe!
This superstar fitter also ignored the cut out in the side of the sink and set it far too far backwards and then was puzzled as to why it didn't fit properly.
Wickes sent out a second installer mid-May, who was supposed to sort out the problems caused by the first installer. He reckoned it was the wrong sink (it wasn't) and he didn't spot that installer #1 had fitted the sink too far back either! What a star!
It is a real wonder that these two "professionals" managed to breathe on their own without instructions and a YouTube "How to" video.
Still, we can now put this whole shambolic episode behind us and never, ever pay a company like Wickes (or Wren for that matter) to install a bathroom or kitchen.
Go local with an installer recommended by a friend and support the small guys. They rely on local trade to exist and if they do a bad jod, they don't last long.
