The other stinky thing is vinyl non-slip mats for the tub. I have someone crashing at my place for the next week, and- acutely aware that my standards of 'clean' are not as other people's- decided to get a new bath mat because the hard-water/ mold/ soap scum discolourations on the bottom of my mat no longer respond to bleach. But oh yuck the smell! Maybe my crashee will ignore the occasional little brown rings? (Then there's the shower curtain itself, oh dear...)
Then again, other people may not smell these things at all. Sensitivities are weird that way. The older of the two Little Girls hogs the remote and keeps the volume level at 2 because other people turn the sound up to where it hurts her ears. Apparently when they do family night watching, she wears ear-plugs so her parents (and, presumably, uncomplaining younger sister) can actually hear the dialogue.
