Where bathroom cabinets are concerned, the traditional style-wall mounted options are great if you have loads of room but not all of us do.
Corner bathroom cabinets are such a good space-saving idea I wonder why we don’t see more of them? You often get a decent sized mirror and a handy shelf, or three, which may be limited in width but when you have so many small items to store it’s worth taking any option you can get!
