Yes, if the jewellery is Solid gold/silver, platinum, palladium, stainless(surgical) steel, or titanium, you're safe to shower with it. Other metals like copper, brass, bronze, or other base metals not recommended to touch the water.
Yet, for that we recommend our Solid S925 or Stainless(surgical) steel material designs in silver colour (❀╹◡╹)
The reason is those 2 material's original colour is silver. Gold & rose gold colour are vermeil colour so, depends on how managed can be removed over time. So getting silver will have a very long-lasting colour!
For S.steel material how to vermeil rose gold colour is 2nd coated above gold. So the colour may look more yellowish than S925 jewellery and overtime when the rose gold is gone, the gold colour will be revealed. And at the last turn to the original silver colour.
+ This timeline is depends on how managed can be last very long! (few years)
Except for that, material we don't recommend touching any of oil/chemical/water/lotion/perfume or exposed at the outside for long time. And recommend not wear while sleeping/exercise because can cause more injury if have some accident.
