We are re-doing are kitchen, and the Ikea Faktum base units we have installed are only 4 years old. We can no longer buy anything from Ikea for these units as they've changed to a new system I was looking at the Wren kitchen installation guides and cabinets at the front sides and bases look very similar. They look like they use the same clip on door hinges and the holes up the sides look identical, as do the feet. I don't know if they all confirm to EU standard with this type of thing (it would make sense!) Do you think i could re-vamp kitchen using Wren door fronts and fittings using the old Ikea base units, and then just have a new work top installed over them??? Any feedback appreciated.
