3-in-1 Bathroom Heaters & Exhaust Fans

Why Choose a 3-in-1 Bathroom Heater & Exhaust Fan?

A 3-in-1 bathroom heater/fan/light unit offers three essential functions—heating, ventilation, and lighting—in a single ceiling fixture. Instead of installing separate heater, light, and exhaust units, you get an efficient all-in-one solution that saves ceiling space, reduces clutter, and ensures coordinated performance. These units help control humidity, reduce mould, warm the space after a shower, and provide illumination—all in a compact, seamless installation. In modern bathrooms where every fixture matters, a quality 3-in-1 unit adds comfort, functionality, and style.

Trusted Brands in Our Range

We stock 3-in-1 bathroom heater combinations from reliable manufacturers known for performance and design:

  • Brilliant – innovative bathroom heating solutions with modern styling

  • Martec – strong reputation for effective ventilation and thermal performance

  • Mercator – trusted Australian brand offering balanced heater/fan/light combinations

Selecting any of these brands ensures a durable and coordinated solution that suits typical Australian bathroom conditions.

Available Colours & Finishes

Choose a finish that suits your bathroom aesthetic. Our 3-in-1 units are available in:

These options balance clean design with contrast or subtle integration, depending on your room décor.

Product Categories & Application

Our collection falls under two key functional categories:

  • Bathroom Heating & Ventilation — units focused on providing strong extraction and heat functions, ideal for controlling humidity and warming the room

  • Heating & Cooling — models that may include additional features or modes (e.g. fan-only cooling or adjustable modes) in cold or warm climates

You’ll find units suited to different bathroom sizes and usage patterns depending on the performance required.

Installation & Performance Tips

When selecting a 3-in-1 unit, always match the extraction rate (air flow in m³/hr), heater power (watts), and lighting output to your bathroom size. Proper ducting, grille positioning, and ceiling clearance are essential to ensure performance. Always install on robust ceiling framing, and ensure electrical wiring, fan isolation, and safety standards are met. For lighting, consider combining with other fixtures if the built-in illumination isn’t sufficient for your layout.

Key Benefits of 3-in-1 Bathroom Heater Units

  • Combines heater, fan and light in one compact fixture

  • Saves ceiling and wall space by replacing multiple units

  • Controls moisture and keeps the bathroom warm post-shower

  • Offers coordinated lighting, heating and ventilation performance

  • Available in black or white finishes to suit your style

3-in-1 Bathroom Heaters & Exhaust Fans FAQs - Frequently Asked Questions

A 3-in-1 bathroom heater and exhaust fan is a combined unit that integrates a heat lamp, exhaust fan, and overhead light into a single fixture. This multifunctional design saves space and provides efficient heating, ventilation, and lighting solutions for bathrooms.

The heat lamp emits infrared radiation to warm the bathroom quickly. The exhaust fan removes moisture and odors, preventing mold and mildew growth. The overhead light provides illumination, all controlled by separate switches for convenience.

Yes, these units are designed to be energy-efficient. The heat lamps use infrared technology to provide quick warmth, while the exhaust fan operates only when needed, reducing energy consumption. Always check the product specifications for energy ratings.

Installation should be performed by a licensed electrician to ensure safety and compliance with local regulations. The unit is typically recessed into the ceiling, with the exhaust duct venting to the exterior. Refer to the manufacturer's installation guide for specific instructions.

While some homeowners may attempt DIY installation, it is strongly recommended to hire a licensed electrician. Improper installation can lead to safety hazards and may void the product warranty. Always follow the manufacturer's guidelines and local building codes.

Regular maintenance includes cleaning the heat lamp and exhaust fan to remove dust and debris. Ensure the exhaust vent is clear to allow proper airflow. Refer to the manufacturer's maintenance instructions for specific care guidelines.

When installed and maintained correctly, these units are safe to use. Always follow the manufacturer's safety instructions and ensure the unit is installed by a qualified professional. Do not use the heat lamp if the protective cover is damaged.

Yes, the heat lamp provides instant warmth to the bathroom. However, it is designed for supplementary heating and should not be relied upon as the sole heating source for large bathrooms. For comprehensive heating, consider additional heating solutions.

It is not recommended to install the unit directly above a shower or bath due to moisture exposure. Follow the manufacturer's guidelines for safe installation locations to prevent electrical hazards.

Consider factors such as bathroom size, desired heating capacity, and additional features like LED lighting or humidity sensors. Consult with a professional to select a unit that meets your specific needs and complies with local regulations.
