Key safety upgrades for basement bathrooms include installing a ground-fault circuit interrupter (GFCI) outlet near the vanity, adding an exhaust fan rated at least fifty cubic feet per minute, and removing any mystery cords running through walls. A GFCI protects against electrical hazards in damp conditions. Ventilation reduces moisture and mold risks, enhancing health and comfort. These fixes improve peace of mind and contribute as much to a safe vibe as lighting and design.
