After getting a tattoo, it is generally recommended to wait at least 2-3 weeks before swimming. This waiting period allows the tattoo to properly heal and reduces the risk of infection or damage to the tattoo. Swimming pools, oceans, and lakes all contain bacteria and other microorganisms that could potentially cause an infection if they enter the fresh tattoo. Additionally, soaking a new tattoo in water for extended periods of time can soften the scabbing and interfere with the healing process. It is important to follow the aftercare instructions provided by your tattoo artist to ensure proper healing and to protect the quality of your new tattoo.
