We have recently supplied painted hardwood Shaker Doors to fit to existing IKEA cabinets. The client was attracted by the option to have them painted hardwood rather than just MDF. Our standard hardwood doors are 22mm thick, but on this occasion, to be able to match the existing cabinet, we made the doors to 18mm thickness.
They were painted with the colour from Farrow & Ball 'Cornforth White Eggshell'.
They turned out really well and we had some brilliant feedback from the client!
