If you have gauges made of wood, it is generally okay to shower with them in. However, there are a few things to keep in mind. First, avoid getting soap or shampoo directly on the wooden gauges. This can cause the wood to swell and warp. Second, be sure to dry off your gauges after showering to prevent water damage. Third, if your gauges get wet while swimming, take them out as soon as possible and rinse them off with fresh water. fourth, If you accidentally drop your wooden gauges on the floor, inspect them for cracks or chips before putting them back in.
