Factors You Should Consider Before Purchasing the Best Small Heater for Bathroom

Factors You Should Consider Before Purchasing the Best Small Heater for Bathroom

Take a look at the following criteria before choosing a small heater for your bathroom.

Heat Output

The first criterion you should consider before buying a heater is to check its heat output. In other words, how much BTUs it provides matters a lot. The higher the number will be, the more efficiently a heater heats your room. For example, Stiebel Eltron Heater offers 5118 BTUs, which is enough to warm your small bathroom or dressing room. 

Heating Method

Not every space heater comes with the same heating method. Some of the heaters offer convection heat or infrared heat. The infrared heater heats the object or people directly. Such a heater will be great for heating small spaces like a bathroom. On the other hand, a convection heater draws the cooler air and passes it over a heating element to warm the cold air. Then, it circulates the warm air around your room. Both heating systems have upsides and downsides. Go for an infrared heater if you want to warm a room without wasting energy.

Ease of installation

Most space heaters in the market now come in fully assembled. For example, the Lasko heater on this list requires no assembly. Just unbox it, put it in your room, and get the heat you need. Every heater we mentioned includes an installation guide. Following the guide, you can assemble the unit by yourself. 


Each of the space heaters we reviewed is lightweight and portable. You can carry them from one room to another and heat a specific area to boil the frigid condition. 

Include safety features or not

Safety comes first! Every space heater has an automatic shut-off feature, tip-over protection feature, and overheat protection system. If the heater gets overheated or tipped over accidentally, the unit will shut down to avoid potential accidents.


What is the best type of heater for a bathroom?

A convection heater will be best to heat your bathroom as you need to warm the space for a long time. Regarding this, Lasko CD08200 will be your best pick. This heater will heat the air fast and turn your space into a cozy room.

What is the best way to heat a small bathroom?

Placing a convection heater in a small bathroom is the best way to heat the ice-cold area of your house.
