I'm actually a pretty clumsy person, so I'm surprised it took me this long to actually drop one of my toys in the shower while I was using it... The toy itself is undamaged, but it was a communal shower (two showers for a floor of approximately 20 girls). It's made of TPE and I scrubbed it with an antibacterial hand soap. But what do you think? Is it porous enough that a few seconds on the floor of a shower that people wear their sandals into would make it potential harmful to my body?
