Hello npfaeffli,

Thank you for your enquiry. Thanks to the waterproof handpiece, the shaver can also be used in the shower.

Kind regards,
Your Philips Care Team

Yes, it can be used in the shower or with shaving foam (I think you need to let it dry for 1-2 days before connecting it to the charger and shake it to drain the water inside). It has a shower-bath symbol on the back.

The head can be rinsed under the tap, but I wouldn't use it in the shower.

Never tried that, but i rinse it every time after shaving and so far it did not break. So maybe i would not go scuba diving with it, but bathroom stuff is probably ok.
