For suction cups to stick to the tiles in a bathroom,the tile
must be thoroughly devoid of dirt and oils ie wipe with turps or
meths. The cups also must be cleaned.

The tiles should also have a smooth, glossy surface.
Some tiles have some texture that will allow air
to gradually get under the suction cup.

One thing you might try is a very thin coating of
petroleum jelly around the rim of the suction cup
to act as a gasket.


The tiles are old (30 years maybe) so perhaps they are invisibly
pitted. I'll try the petroleum jelly approach.
