Undersink Cupboards - 600 & 800

If you are fitting a Belfast/French Farmhouse sink, there are particular designs that we recommend. For the F600x200US cupboard, please look at the Villeroy & Boch Farmhouse 60 sink. If you are considering the F800x220DUS cupboard, please look at the Villeroy & Boch Farmhouse 80 sink. The heights of sinks can vary and we have based our cupboards around these particular sinks, which we know and like.

This doesn’t mean you can’t use a different sink, or indeed a reclaimed one, but the sink you have chosen must not be taller than the intended sink height for your chosen cupboard. If you are using the 600mm wide cupboard, the max height is 200mm, whereas the 800mm wide cupboard is 220mm max height. If your sink is shallower, you will have to provide a packer beneath it so that sits up against the underside of the worktop. The bottom of the doors in this run should line through. If you take more off the height of the cupboards to accept a deeper sink, the cupboard doors will then be out of line and this will not achieve the desired effect.

This should be scribed to the floor as described in the fitting instructions for Floor Cupboards. We recommend cutting a neat hole in the back panel to allow your plumbing to exit the cupboard and run behind the cupboards. As there isn’t much room in these cupboards, we would suggest that you use a ‘space saving trap’ to save on the height. This will allow your adjustable shelf to sit a bit higher and maximize the space below.

When positioning your sink on the cupboard, you ideally want to pull it forward so that it stands proud of the front of the cupboard run by the radius of the sink corners. Aim to align the front face of the cupboards with the point at which the sink radius meets the flat of the cupboard sides. Once you have done this you may find that the sink doesn’t sit entirely level due to how it was cast. If so, use small shims to pack it up and level it. You ideally want the sink to sit slightly below the top of your neighbouring cupboard to allow for a bead of silicone to seal the top of the sink to the underside of the worktop.

With the sink in position, mark the location(s) of your waste holes onto the cupboard and follow the fitting instructions for your waste and sink to make sure they correlate. At this point you may notice that the sides of the sink aren’t dead vertical and have a slight undercutting angle to them. We recommend using small infill strips of timber, but to size and position them behind each leg so that they fill this ‘wedge’ shaped void. You can fix them into position using pins or similar.

Once you are happy with the level and positioning of the sink, remove it from the cupboard and cut the holes out for your waste(s). Replace the sink and reestablish the level of the sink using the shims. Remove the sink again (careful not to disturb the shims) and squeeze four biscuit sized blobs of silicone on the base for the sink to settle on. Return the sink and bed it down on the silicone, again careful not to dislodge the shims. This should see your sink in position and ready to accept your plumbing, waste and worktop.
