Can You Motorise Bunnings, Spotlight & Other Off-the-Shelf Roller Blinds?

Sometimes. A roller blind bought from Bunnings, Spotlight or another retail store may be possible to motorise, but the shop it came from does not tell you whether a motor will fit. What matters is the actual tube inside that specific blind: its diameter, wall strength and internal profile.

Why there is no simple retailer-by-retailer answer

Retail ranges change, suppliers change and different sizes within a range can use different hardware. Two blinds bought from the same retailer can therefore have different tubes. Compatibility needs to be checked on the blind in front of you, not inferred from the logo on the packaging.

What you need to check

1. Remove the blind and take out the idler end.

2. Measure the outside diameter of the bare aluminium tube.

3. Take a straight-on photo of the internal profile.

4. Check whether the tube wall looks substantial or unusually thin.

5. Compare the tube with a known motor-ready profile before buying any motor.

Why thin retail tubes can be a problem

Off-the-shelf blinds are often designed around low cost and manual chain operation. Some use thin-wall tubes or small diameters that do not have the stiffness or internal locking profile required for a reliable tubular motor retrofit. That does not make the blind unusable; it just means the tube may need to change.

What if the tube is compatible?

If the profile matches one of the recognised systems and the blind is an appropriate size, you can follow the same process as any other retrofit: choose a motor confirmed for the tube, use the correct crown and drive, replace the chain control and program the motor.

What if the tube is not compatible?

You may still be able to keep the fabric. Replacing the tube, brackets and idler with a motor-ready system can turn an inexpensive manual blind into a suitable platform for motorisation. The economics depend on the blind and the motor you choose, but it avoids discarding good fabric unnecessarily.

Start with our roller blind tube identification guide. If your tube matches S45, S40, 38mm, S60, HD50, S35 or L45, follow that tube to its confirmed motor options. If it does not match, read our tube replacement guide before deciding what to buy.

The rule to remember

Do not ask 'Can a Bunnings blind be motorised?' Ask 'What tube is inside my blind, and is that tube motor-ready?' That question leads to an answer you can actually rely on.
