How to Heat a Bathroom Without Central Heating

Not all homes have central heating—and some people prefer it that way. It’s sometimes more energy-efficient to just install heating devices in the room, so you can set the temperature according to your preferences and needs.

Bathrooms are one of the coldest rooms of the house, and nobody likes stepping out of a warm shower into the cold or placing their feet on chilly flooring. So, if you’re struggling to keep your bathroom warm without central heating – here are some toasty solutions.

1. Infrared Wall Panel Heater

A wall panel heater is ideal for small bathrooms. The wall-mounted panels are as thin and unobtrusive as a mirror. They won’t take up space, and they look sleeker and more elegant than traditional heaters.

SUNHEAT Mirrorstone 700W Far Infrared Wall Panel Heater also gives you more control over the room temperature and your energy consumption. Unlike bathroom radiators, which just usually have a basic dial, you can set a specific temperature and even program when it turns off.

  • Save on electricity bills. This wall panel heater is not only affordable, but it can also help you lower your heating costs by up to 50%. It consumes just 30% of the energy required by radiators and other kinds of heaters—you’ll spend just a few cents for every hour of use!
  • Smart temperature sensors.  The “intelligent” heating will keep your bathroom as warm as you like it—turning on when it senses a drop in temperature and turning off once it reaches your desired levels. It’s energy-efficient, more convenient, and prevents overheating.
  • Safe for bathrooms. Not all wall panel heaters are safe to use in the bathroom, but this one is! The waterproof casing ensures that the internal wiring is never affected by bathroom moisture or accidental splashes.
  • Beautiful casing. The casing uses a VOC-free paint that won’t peel or discolour over time. You can also repaint it to match your bathroom design scheme.

2. Install a Heated Bathroom Floor

Traditional heaters will warm up a room by heating the air. However, many bathrooms have cold spots that stay chilly despite switching up your radiator to the highest setting.

Several things can cause cold spots. That includes the bathroom flooring (tiles and marble are inherently cold), or hidden pipes that are prone to condensation. Since it can’t be solved through radiant heat, the next solution is to heat the floor itself.

Heated bathroom floors may need more time to install, but they don’t need any maintenance and are about 25% more energy-efficient than systems that use forced air. That’s because it retains the heat, rather than dissipating it around the whole room.

  • Simple installation. These heated mats come in rolls that you can cut to the size of your bathroom floor. It can be installed under any type of bathroom flooring: porcelain, ceramic, stone, mosaic or even vinyl floors. You can DIY it if you have some carpentry experience, or you can hire someone to help you out for the day—but either way, you will need an electrician to help you with the wiring.
  • Precise temperature controls. Have full control over your underfloor bathroom heating with the LCD screen. Adjust the temperature with a few clicks of a button, or use its 7-day program feature. You can also opt to upgrade to a WiFi-enabled thermostat, or a smart thermostat that lets you set a schedule or choose Vacation or Energy-saving modes.

3. Portable Panel Heater

Do you want the sleek, minimalist design of a wall panel heater, and the option to use it in any room of your house?

An IP24 portable heater is ideal for people who want the option to move the heater—any time, anywhere. Maybe you live in an area where the bathroom only gets cold during the winter, or you just want the option to move it from the bathroom to the guest room when someone comes over.

  • Versatile. You have the choice between mounting it on a wall or placing it on a stand.
  • Safe to use. It automatically turns off when it reaches a certain temperature or accidentally tips over.
  • Timer function. You can program it to turn off after a certain number of hours. Now you never have to think, “Did I remember to turn off the heater?”
  • Fast heating. Its powerful convection heating makes the room noticeably warmer after just a few minutes.

4. Heated Bathroom Mirror

Don’t you just hate it when your mirror fogs up after you take a hot shower? A heated bathroom mirror prevents condensation and will always stay clear—and has the extra benefit of warming up the rest of the bathroom, too.

This type of heating system works best for very small bathrooms, where you don’t have space for a radiator and may not need a very strong heater. Though some heated bathroom mirrors can emit a lot of heat, they will not be as energy-efficient or as powerful as a wall panel heater or a radiator.  

  • Dual function. You get a high-quality mirror and a heater, thus maximizing your bathroom space
  • Dust-free. Unlike heaters that blow air, infrared heat won’t stir up any dust or allergens. It’s ideal for people with asthma, allergies or sensitive skin.
  • Quiet. Some heaters can be noisy because of the mechanical parts. The infrared heater mirror quietly gets the job done.
  • Safe to use. The convection heater doesn’t store heat, so after you turn it off the mirror quickly returns to its regular temperature. It is also waterproof, so it can get safely splashed without danger.

5. Wall mounted Fan heater

During the cold months, it heats up the bathroom. When it’s summer, you can use the fan to keep the room cool. It’s an affordable and practical way to keep your bathroom at a comfortable temperature, in every season of the year.

Fan heaters are also compact and can be installed on the wall to save on floor space. Conveniently control the temperature with remote control, and set the timer to turn off automatically.

  • Precise temperature controls. The temperature is accurate to within 0.2 degrees, so you maintain a consistent temperature and don’t waste money on heating the room more than necessary.
  • Simple and easy to use. Use the touch panel to set the timer, temperature, and other settings. You can also select from 5 pre-set heating programs.
  • Switchable power settings. You can choose between a 1 or 2-kilowatt setting.
  • Programmable timer. You can set a schedule for turning it on and off. On very cold winter nights, use the timer with the anti-frost setting to prevent the pipes in your bathroom from freezing.
  • Energy efficient. The heater is compliant with energy efficiency standards like the ERP LOT 20.

Tip: One final tip for those who have a loft directly above their bathrooms. Lofts are super cold in winter – they’re designed to draw cold out from outside, and often the only thing separating your bathroom from this cold air is some sheets of plasterboard on the ceiling.

If you have poor insulation installed in the loft, it will be hard to keep your bathroom warm, as you’ll lose all that heat (which rises) out of the ceiling. It’s a good idea to invest in the best insulation you can afford for your loft, which will help insulate heat within your bathroom.

Another idea is to combine two of these methods from the list for optimal heating across the whole bathroom. For example, instal floor heating and fan heater or infrared panel.
