Hi everyone - as promised I am posting images of the bathroom cabinet I found and the quick improvement I made. It was just a single mirrored cabinet which needed some cleaning up and TLC and will certainly do us well for now - this is the Before image:
I also had some spare satin finish knobs, from when we bought knobs from ebay for the kitchen, so I replaced the small pine knobs that were on the unit with new shiny satin ones which look much nicer.
It is a very basic makeover, but cost nothing whatsoever apart from carrying the unit home and spending some time on it.
The bathroom is now decluttered and brighter as the unit has a mirror and is white so I'm very pleased with the results!
