Best Space Heater for Bathroom Buyers’ Guide

4 Types Of Bathroom Heaters


As the name suggests, these are heaters that you can transfer between rooms easily. They are usually made very compact and lightweight to make transportation easy. Portable heaters are great when you only need the heating at certain periods of the year. Another situation where they might be suitable is when you are a tenant and you have no option for a permanent fixture in the bathroom. Evidently, portable bathroom heaters are built for convenience. Therefore, their heat output may not be the best and they are generally suited for smaller sized bathrooms. 

Wall Mounted

These bathroom wall heaters are mounted on the wall of your bathroom. They can either be surface mounted or installed into a recess of the bathroom wall. These are suitable for bathrooms where space is limited on the floor as they are hung on the wall. Installation of these heaters are generally straightforward and can be done by most homeowners. However, when positioning these heaters, do take note that they won’t be blocked by the bathroom door as it is a common mistake among homeowners

Ceiling Mounted

Similar to wall mounted heaters, these heaters are also great in bathrooms where space on the floor is limited. An additional advantage of mounting it on the ceiling is that there is less chance of obstruction by objects. In terms of safety, they are also better as they are almost always far away from the water in bathrooms. Installation of ceiling mounted heaters is also generally doable by homeowners. If the homeowner feels uncomfortable dealing with these, you may also contact your nearby electrician.

Combination with Exhaust Fan

Understandably, the bathroom is an extremely humid place. When we take a hot shower, there is a lot of steam generated which will be distributed around the bathroom. These moisture may cause damage to your walls and ceilings. With a heater and fan combination unit, the moisture can be removed and the bathroom kept relatively moisture free.

Be sure to read our guide on he harmful effects of humidity to find out how poor humidity control can affect your health!

The Most Important Consideration to Take Note Of

Safety is important in all heaters but it is especially so when the heater is being used in the bathroom. Common sense tells us that electrical appliances don’t go well with water and water is the most abundant in a bathroom. If not managed properly, this is a clear recipe for disaster.

Here are some tips that will help you design a safe bathroom.

Designed For Bathroom

Make sure that the heater has been designated for bathroom use by the manufacturer. These heaters are usually waterproof and are generally safe for use in a damp bathroom.

Position Of The Heater

Even though bathroom heaters are mostly waterproof, you still wouldn’t want to test the system by exposing it to water. Therefore, place the heater as far as possible away from the water. Therefore, wall mounted and ceiling mounted heaters are safer because it will be quite difficult for water to get splashed onto them. When positioning the heater, also ensure that it won’t be obstructed by the bathroom door. 

Having a Ground Fault Circuit Interrupter Outlet (GFCI)

The GFCI can be recognized by their red reset button and black test button. To put it simply, the GFCI outlet cuts off the power supply when it detects a huge difference between the power it supplies and the power it received. They act to prevent short circuits and dangerous shocks.

Having a Appliance Leakage Current Interrupter (ALCI)

Similar to GFCI, the ALCI is a circuit breaker on the appliance that will detect large differences in the power it supplies and receives. Once detected, they will break off the circuit almost immediately and prevent electrical shocks. 

Do Not Hang Clothes On the Heater

This is pretty self explanatory. Hanging clothes on the heater is a fire hazard as the clothes may catch fire in the event of an overheat. If you would like to have warm clothes or towels to use after your shower, consider installing a towel warmer instead.

Home fires are a real threat and usually arises due to improper usage. Do visit our guide here on the best heaters for seniors as we also touched on how to reduce the risk of home fires with proper usage of space heaters


For any heaters that is going to be near water and moisture, there is a higher chance of failure and malfunction. As much as we try to be careful with our heaters, they are just generally more prone to spoil. Therefore, it is crucial to have a heater with a longer warranty so that there is always the option of getting a new unit if the heater gives up prematurely.
