Low water pressure in bathroom fixtures can have various causes, including mineral buildup in faucet aerators, partially closed water shut-off valves, clogged or partially closed water supply lines, issues with pressure regulator or leaking/corroded pipes. Municipal water supply issues, water heater problems, faulty pressure reducing valve, clogged showerhead or tub spout, and plumbing design or sizing issues can also contribute.
