Having had three quotes from kitchen companies, it is rapidly becoming plain that the modern combi boiler is too large to fit into a standard wall cabinet. B & Q just shrugged, Magnet suggested a tambour unit which would look good but would not work because the boiler would interfere with the rolling mechanism. Surely these boilers have been around long enough now for the companies to sort out a solution? That aside, John Lewis can supply a cupboard that comes down to worktop level and is deep enough to hide the boiler but alas it has a glass door. What I was wondering is whether it would be easy to replace the glass with mirror-glass instead? Had anyone tried this? Or indeed, has anyone else had experience of this problem and how to solve it? Many thanks.
