Can a bathroom sink have an S Bend as apposed to a waste trap?

Of course not. There is no such thing as a bathroom sink.


Apart from preventing smells coming up the pipe, is the traps main
function
to collect anything that gets dropped down the sink and if so then why
does
a bath not have this?

It does.

I think what Frank means by "trap" is a Bottle Trap. An S bend is a trap as
well, Frank. So is a P trap. You can get S traps, P traps and bottle traps
in all diameters, 32mm for washbasins and bidets, 40mm for sinks, baths and
showers and 50mm, usually for Urinal bowls and large sinks. You can also
get shallow 40mm dia P traps for tight spaces under baths and showers. If
you want an S trap for a basin, you need one of these, in 32mm or 1¼"
diameter:

The trap's function is to provide a water seal to prevent bad smells from
the sewers. Luckily, they all catch dropped jewellery too. This type can
be disassembled very easily to do that.
