In such testing economic times, chances are you
Bathroom Lights - The first, easiest and probably most popular change is to buy energy efficient light bulbs and install them in your bathroom (and every room around the house for that matter). 60-watt light bulbs were pulled out of production back in September 2011 and are no longer on sale from electrical wholesalers in the UK, so finding energy efficient alternatives should be a relatively easy task.
Energy efficient bathroom lights will cost you a bit more than the traditional ones using 60-watt light bulbs used to cost, but in the long term they are definitely the best money saving alternative as they can greatly reduce your electricity bill. They are also a green alternative which is great for helping to protect our environment and improve the energy efficiency of your home.
Underfloor Heating - The great thing about underfloor heating is that it requires less energy to heat your bathroom than traditional radiators, which can go on to save you a substantial amount of money. Underfloor heaters also ensure that the whole of your room is evenly heated, from the bottom to the top, whereas traditional heating methods such as a radiator will leave one side of your bathroom a great deal warmer than the other.
With underfloor heating you also have greater control of the temperature you wish to use to heat the room, meaning you can increase/decrease the temperature easily depending on the weather conditions. The final benefit is that the bathroom tends to get a bit wet from time to time and the underfloor heating will quickly work to dry your bathroom floor, making it a safer environment.
Insulation - Another critical addition to your new energy efficient bathroom (or any room around your home for that matter) is the use of insulation in the wall cavities and ceiling of your home. This will work in tandem with features such as the underfloor heating as it will help to trap the heat emitted meaning your bathroom will stay warmer for longer and you won't have to be turning on the heater every 5 minutes.
Sky Light - As we move further in to the 21st century, one feature which is becoming increasingly popular in the modern bathroom is the installation of a sky light. The reason they're so popular is that they reduce your dependency on artificial lighting in the bathroom as the natural sunlight which is beaming through the roof is lighting up the whole room (in the daytime) with natural sunlight. As with most suggestions this has both financial and environmental benefits, as it helps to light the bathroom for longer.
