If you're experiencing low water pressure in your shower, there are a few potential culprits. First, check to see if the issue is isolated to your shower or if it's affecting your entire home. If it's just your shower, the problem is likely with your shower head or faucet. Clogged shower heads and mineral deposits can restrict water flow and cause low water pressure. If your entire home is affected, the problem is likely with your main water line or pressure regulator. These problems are best addressed by a professional plumber.
