3 in 1 Bathroom Heater Review - Our Best 3 in 1 Bathroom Heaters 2020


What is a 3 in 1 bathroom heater?

3 in 1 bathroom heaters are a compact all in 1 unit, they will consist of a light, an extraction fan and heat unit. 

What are the benefits of 3 in 1 bathroom heater?

Having a 3 in 1 bathroom heaters are crucial for ventilation. Having adequate ventilation is paramount for removing stale air and unpleasant smells.  These are now needed to be met by the building code of Australia, these can cause uncomfortable and unhealthy living conditions. Condensation occurs when the moist warm air comes in contact with cooler surfaces such as walls, ceiling and windows. This leads to mould, peeling paint and timber decay. Having a high quality extraction will avoid this. 


Things to consider when buying

Whether you're considering a complete bathroom renovation or you're just looking to update your existing unit, buying these can become very confusing, even after years and years selling them I still learn new information and how the technology within them is evolving.

With the 3 in 1 bathroom heaters they will consist of the light, extraction fan and heat. With each manufacturer they will normally only do 1 of the 3 very well, this means you need to know what specifications will benefit your bathroom most. 

In this blog I will run through all the specifications you will need to look at before buying your bathroom heater and what they actually mean. 



Air Extraction 

The extraction for majority people is the most important specification to get right. 

The extraction will always be measured by m³/hr. The size of your bathroom will depend on how high you need this number.

When installing the 3 in 1 exhaust fan you must not place straight over the shower but instead in the most central part of the room. 

Choosing the right extraction fan for your bathroom is crucial as steam will enter every part of your bathroom and once the condensation starts this creates an ideal place for mould and mildew to create, if you have a high quality extraction this will take the steam before creating these nasty breeding grounds. 


Below is a rough guide for you to work off. 

5m³ Bathroom = 100m³/hr Bathroom Unit

10m³ Bathroom = 200m³/hr Bathroom Unit

20m³ Bathroom = 400m³/hr + Bathroom Unit



The heating feature is very underrated until you need it.

The heating feature should only be used when needed as it creates the heat by drawing an extremely high amount of power.


A rough guide is below to work out how much heat you need for your application.  

5m³ - 10m³ Bathroom - 2 x 275w E27 Globe

10m³ - 20m³ Bathroom - 4 x 275w E27 Globe or 1000w R7 Globe



The lighting is typically a lower level of brightness which is okay for basic functionality.

For medium or larger bathrooms you will still need extra lighting, such as downlights.

All units will include a light, so check which colour temperature is included and try to match to your downlights, most units will have a temperature of 4000k.

When selecting your lighting plan, you will want use LED Downlights evenly across your bathroom and 1 right over your basin, this will assist for a more practical use over your vanity.

Another good option is to have strip lighting running underneath your bathroom vanity and along the the mirrors top or sides.

When measuring how much light you need for a bathroom you must go off the lumens and not the watts.  For a bathroom you want to have around 500-600  lumens per SQ/M.

Another point to check when buying a new bathroom unit is that the light is replaceable, some will have a built in LED board which is non replaceable, this means you will need to replace the whole unit, look to purchase a model which takes LED globes that can be replaced. 

Best Bathroom Lighting 2019



Today's market now have a very wide range of 3 in 1 bathroom heaters, to the point now they are a statement piece which tie in with the rest of the bathroom instead of hiding it with the same coloured ceiling. A black option like the images below have been a real hit in 2018. 

Best Exhaust Fan 2019 The Lighting Outlet

3 in 1 Bathroom Fan Run on Timer - Most bathroom heater units will turn off when you turn off the switch and walk out the room, however the steam is still there but you don't want to waste power because you don't know when you will be back to turn off. A great solution for this is a run on timer, this allows the extraction of air to continue for a set amount of time and remove all moisture.

The Lighting Outlets Best 3 in 1 Bathroom Heaters



This bathroom heater fan has now been the lighting outlets best 3 in 1 bathroom heater by far.

As discussed earlier a lot of fans will do 1 out the 3 aspects well, however Martec have done 2 out of the 3 very well.

The extraction is by far the best for this price range and competitors which moves 600m3/hr, this will suit any medium and large bathroom easy.

The lighting in this bathroom heater unit is also very bright and interchangeable with GU10 LED globes @ 9 watts x 4.

The finish on this 3 in 1 is also a great feature, it is a very slimline clean finish which looks very high end.

The only downside to this 3 in 1 is the heat option, the linear heater takes a R7 1000w globe, we have found these globes blow often and use a lot of power, use this feature modestly. When changing the R7 globes also note to not touch the globes with your bare hands as the oil from your fingers will blow the globe much quicker, use a tissue or gloves.

The linear by martec also comes in a mini linear version which is a great 3 in 1 bathroom heater for a small bathroom.

Sahara By Ventair SAH31BL, SAH31WH

The Ventair Sahara 4 in 1 is one of the newest to hit the market and we have had an overwhelming response on it’s performance and the look. This exhaust fan is the closest you will get to an architectural look.

Ventair have gone one step further by making this a “4 in 1 fan” which means you have both a heat option and a cool option with the fan. As this runs off of ceramic coils this means you won’t have to replace the heat globes constantly, resulting in very low maintenance.

This 4 in 1 fan also performs extremely well with an extraction output of 380m³/hr, this would work well even within in a large 30m³ bathroom.

The light output is 1500 lumens (most competing fans only reach 1000 lumens), with this additional brightness it allows you to have this as the main source of light in a small to medium size bathroom. For larger rooms we recommend additional lighting by adding downlights over your vanity.
The sahara has been backed with a 5 year warranty which again is much stronger than it's competitors with most providing only 3 years.

Mercator Domino 3 In 1

It's a pleasure to review the Domino 3 in 1 bathroom heater as it's currently our best seller, all down to it's a tremendous value. The Mercator Domino exhaust stacks up with all its competitors in performance but is much cheaper.

The Mercator Domino's best selling point is the high extraction of 500m³/hr which is extremely high and will suit medium to large bathrooms easily. It includes a 3-year in-home warranty for everything but the globes which means if it breaks the supplier will come to you and fix it or replace it.

We can't recommend the Domino by Mercator enough, it looks modern, has very high performance and is backed by one of Australia's largest brands with 3 years warranty. 


Regent V2RHLEXWHAG By Ventair

This 3 in 1 bathroom heater unit is a great seller for the lighting outlet online.

This is down to people really doing their research and coming to the conclusion that this 3 in 1 bathroom unit has it all.

Great modern look, great air movement of 350m³/hr, 1000 lumens of brightness and also has a good heating option at only 1000 watts. 

This is a great overall fan which will last the distance and will not require any maintenance for many years. Ventair are in a league of their own and are having a massive impact on the advancing technology of fans and heaters. There products are very original and quality. 

In Conclusion

There's so many different options and we know a lot of this information can be overwhelming.
