Baths do not scale in cleaning power, showers are ineffective.

[FantasticFwoosh]

Describe the bug
Baths are meant to be ranked in effectiveness, but are more or less not worth the investment beyond aesthetics because they all clean to the same rate, as was unintentional by the PR creator.

Showers are similarly devalued despite having a additional role of keeping away radiation and cleaning clothes a little bit before #289 was added which does not seem to be being fufilled.

To Reproduce
Steps to reproduce the behavior:

1. Create a Stone and a Bronze/Iron/Metal bath, and a Shower
2. Get naked and dirty and get inside and turn on
3. Probably var-edit yourself back to full dirtyness or go from bath to bath/shower, cleaning yourself.
4. Your status of dirtyness will not improve beyond 'slightly dirty' rather than 'clean' or 'very clean' when frequented the upgraded metal baths and shower.

Expected behavior
Creating better forms of bathtubs serve as a later game replacement to washing with a pot and maintain a high level of hygiene so you can focus on something else without worrying about the long term degredation of stink lines.

Additional context
It would be nice if development would catch up to let us shower our clothes too while we are still wearing them and standing beneath to knock off a minimal bit of dirt/external blood besides radiation on maps like wasteland once the efficiency of each thing is fixed.
