If you have any doubt about the quality of these units look at my kitchen! I have granite work tops over three meters long and a Fireclay sink that weighs the same as a small child! The kitchen Warehouse units are the tiniest bit deeper than some other online competitors. This is an advantage because by using shallow AEG integrated appliances there was no need to dig out the walls for the pipe work. I have a perfectly flat cupboard run. I didn’t pay the ten per cent extra to have the units assembled, but the fitter found them very easy. Tips The plinths have the same lovely wood grain effect as the units. Buy extra to use to box in pipes elsewhere in the kitchen, or use as packing. If you are considering buying a 1000cm base unit, then seriously consider paying the extra for the drawer unit instead. So much more storage and they look wonderful. Left over Amtico flooring planks, I store under the kitchen units, then conceal it with the plinths. This way when disaster hits the floor in five years time you can always find exact match flooring. Think very carefully about the size of the wall units! Very easy to order the standard 700 ones without thinking too much. But the 900’s are an investment not an expenditure! The customer service is outstanding. At the time of writing if you order a sample door there is a very handy discount code printed on the back of iit! ( don’t shoot me if that has changed by the time you order! And good luck with your project).
