How long the oak wood last in water?

Oak wood can last for several months in water, depending on factors such as water temperature, exposure to sunlight, and the presence of microorganisms. Generally, untreated oak may begin to deteriorate within a few weeks due to fungal growth and rot. However, if the wood is properly treated or preserved, it can endure for years. It's important to note that prolonged submersion can still weaken the wood's structure and integrity over time.
