The Domus Retrofit Range is purpose-built to replace ageing 3-in-1 infrared units without cutting a new ceiling opening, keeping install time and cost down on renovation work. Specifiers and builders get a straightforward like-for-like upgrade path for older bathrooms, without the extra labour of a new cut-out.
Specifying The Retrofit Range For Your Renovation
Choosing the right Retrofit Range model comes down to matching heat output and exhaust capacity to the existing ceiling opening, so the upgrade stays a straightforward like-for-like swap. The sections below walk through choosing the right heater for the application, then how the Retrofit Range fits alongside the rest of the Domus bathroom heater line-up.
Choosing The Right Heater For The Application
The Retrofit Range covers heat lamp, exhaust fan and combined light-and-heat options, and choosing between them comes down to the same factors as any other bathroom heater: heat output, exhaust capacity and IP rating. A compact ensuite being upgraded from an old infrared unit is often well served by a straightforward heat lamp replacement, while a larger family bathroom benefits from stepping up to an exhaust fan or combined light unit at the same time as the retrofit. Because these models are designed to fit the existing ceiling opening left by older 3-in-1 units, matching heat output and exhaust capacity to the room matters more than resizing the cut-out, which keeps the job simpler for the installer. IP rating should still be checked against the bathroom’s moisture exposure, the same as any new installation. Where a renovation budget allows for digital control and faster heat-up times instead of a straight like-for-like swap, the Signature Range is worth comparing.
Specifying The Wider Bathroom Heater Range
The Retrofit Range is designed to sit alongside the rest of the Domus bathroom heater line-up, so a renovation project isn’t limited to a like-for-like swap if the brief calls for more. Where budget allows for the full feature set, including digital control and the fastest heat-up times, the Signature Range delivers premium performance without compromise. For standard spec builds and multi-unit developments where cost-effectiveness matters more than premium features, the Select Range delivers the same core heating and ventilation performance in a more affordable unit. Specifying across all three ranges from one supplier means a renovation project can mix a straight Retrofit Range swap in most bathrooms with a Signature Range upgrade in a feature bathroom, without changing brands or control types. Every Retrofit Range unit is backed by a 5-year in-home warranty and stocked through the Domus Partner trade network, so pricing and availability are a call away for trade and project accounts.
Frequently asked questions
Yes! The digital wall controller emits an audible beep by default whenever a button is pressed to confirm mode selection. If you prefer silent operation, simply press and hold the Standby button for 3 seconds. This will toggle the button-press beep sound on or off.
For maximum comfort and steam control, follow our recommended 3-Step Operation Process: Pre-heat the Room (5 Minutes): Turn on the HEAT function for up to 5 minutes before stepping into the shower. Pre-warming the air and cold wall surfaces significantly reduces condensation formation before steam even starts. Run the Exhaust After Showering: Keep the exhaust running for a few minutes after you finish showering to completely clear lingering humidity. Maintain Cross-Ventilation Placement: Ensure your unit is installed away from corners and positioned between the door (fresh air inlet) and the shower (steam source).
Keep your windows closed for optimal extraction. Counterintuitively, keeping the bathroom window closed produces the best steam removal. Controlled Airflow: Closing the window forces the fan to pull drier air from the rest of the home (usually through the clearance gap under the bathroom door). This sweeps across the whole room, drawing steam away from the shower and straight out the exhaust. Prevents Short-Cycling: If a window right next to the fan is open, the fan will simply pull outside air straight from the window and push it back out, leaving the rest of the room humid and foggy. The Exception: If your bathroom door is completely airtight with zero gap at the bottom, crack the window open slightly so the fan has an air intake source.
No. A single digital wall controller can only be paired with one individual ceiling unit. Because these high-performance units pull up to 2250W each, attempting to bridge multiple heaters onto a single digital control system will severely overload the wall plate circuitry and create an immediate electrical hazard.
Your licensed electrician will follow the detailed schematics supplied inside the unit packaging. Incoming 240V AC mains power connects directly to the main terminal block on the ceiling chassis. The digital wall controller connects to the main unit via dedicated communication wiring. If you choose to utilise the AUX feature for additional lights or a standalone secondary exhaust fan, your electrician will terminate those secondary connections into the available auxiliary terminal inside the main terminal enclosure.
No. The unit's electronic control module is engineered to receive input data from a single master digital controller. Attempting to wire two digital plates together in a 2-way configuration will cause communication bus errors, preventing the unit from turning on.
