Sorry - just seen this.
Are you looking for an IP rated globe to fit to the existing light fitting, or looking to replace the fitting with an IP rated fitting?
An IP54 fitting will be sealed, so cannot take a standard bulb.
You would have to change the light fitting to a flush mounted one with an internal seal for it to be IP 54 like so;
I assume the free standing bath has been moved to now sit under the light?
That's because you cant get an IP 54 rated pendant unless it has a sealed bulb.
There is not a cheap option which is what I think you are looking for.
12v would be the simplest, but it would be a change of fitting or an inset downlighter
