Just put together a tall bathroom cabinet like this:

http://www.ikea-usa.com/webapp/wcs/s...01*13717*10136

The cabinet is skinny and tall so when I touch it on the side it sways. It
rests on four adjustable metal legs. In reading the installation guide
there are two holes on the top where you can screw the cabinet to the wall
to stop the sway. Well my bathroom is an exterior bathroom with CBS
construction and tiled walls, so I am not going to drill two holes through
my tiles especially there is no furing strip behind it where I want to place
this cabinet.

Any idea what I can do to stop the cabinet from swaying? Some sort of
angles or cross brace?
