How do I bathroom / kitchen / extension? etc.

They're all made from the same cheap shitty chipboard, no real difference in quality.

Went with Ikea Metod because:

• No service void, meaning more internal volume. Has the side effect of needing to set the cabinets 50-100mm off the wall if you need to run pipes behind them, meaning you end up with a deeper worktop, which for us was desirable.
  
• Short plinth, again resulting in more internal height and volume. If fitting integrated dishwasher, this will need to have a sliding door mechanism (all AEG, some Bosch/Siemens/Neff/Miele).
  
• Decent quality Blum hinges
  
• Most general builders/chippies have fitted them a thousand times before and know about all the foibles
  
• Really good returns/replacement policy; we returned a load of redundant bits months after purchase for a full refund, no quibbles.
  
  

The only slight qualm is the feel of the drawer runners; as far as I can tell, they use plastic ball bearings and are a bit rough compared to our Hafele slide-out bin runners that use metal bearings.

In an ideal world I'd have got the consummate #£40Kkitchen with metal balls all over the shop, but we managed to do the entire kitchen for ~£6K including all (nearly-new high-end) appliances, custom Douglas Fir fronts, fitted bench seating etc.
