Dry warm towels make all the difference and now you can have them all the time at surprisingly low cost because most towel rails use no more electricity than one or two light bulbs.Towel rails come in various sizes and some are very small so you can be sure that no matter how small a space you have available, one will be suitable for your particular needs.On a cold day, a towel rail will take the chill out of the air as they provide a low level of background heating.
