Including additional features like built-in lighting or electrical outlets in a bathroom cabinets can offer significant advantages, depending on your needs. Here are some considerations:

Built-in Lighting:
Improved Visibility: Built-in lighting, especially around mirrors or inside the cabinet, helps with better visibility for tasks like shaving, applying makeup, or grooming.
Ambience: Lighting integrated into the cabinet can enhance the overall aesthetic of your bathroom, creating a more relaxed or modern atmosphere.
Energy Efficiency: LED lighting options are energy-efficient and provide long-lasting illumination, making it a sustainable choice.
Convenience: If you're looking for convenience, built-in lighting eliminates the need for additional light fixtures or handheld lights in your bathroom.

Electrical Outlets:
Charging Devices: Having electrical outlets inside or near the cabinet is useful for charging electric razors, toothbrushes, hair dryers, or other bathroom gadgets.
Reduced Clutter: Instead of having cords hanging around or needing extra adapters, an outlet within or near the cabinet helps keep your bathroom neat and tidy.
Extra Functionality: Outlets inside cabinets can also be useful for powering other devices like hair straighteners or small appliances without taking up counter space.

Considerations:
Safety: Electrical outlets in bathrooms need to be installed safely, preferably by a professional, to comply with local electrical codes. Wet or damp environments require outlets to be GFCI (Ground Fault Circuit Interrupter) protected to avoid the risk of electric shock.
Space & Budget: Adding these features will increase the overall cost and may require additional space planning. Make sure your cabinet design accommodates these features without compromising storage or aesthetics.
