Found this online.. So as long as no swimming with phone it is ok, but I guess drop in toilet is done deal?
" Your Pixel or Pixel XL is not waterproof. Being splashed or sprayed with water not under pressure and not when the phone is vertical is not even close to being able to withstand being dunked in the pool or dropped in the toilet. This is great if you're caught out in the rain or if you spill water (that's important — these IP ratings are for water only) at dinner, but nothing more extreme. "
