between 42 and 48 inches Click to see full answer. Similarly, you may ask, what size towel bar should I use?The most commonly-available towel bar sizes are 18-inch and 24-inch. However, it’s possible to find in-between sizes of 20- or 22-inch, as well as 30- and 36-inch sizes. The smaller towel bars are meant for hand towels, but any towel bar over 22 inches should be sturdy enough to hold bath towels.Also, do towel rails use much electricity? Towel warmers are usually rather weedy and will not keep a room warm. If yours happens to be 1,000Watts, it will cost 11 pence per hour. Energy from electricity currently costs about four times as much as energy from gas. Your electric heater, tumble drier, and immersion heater will use much more. Similarly one may ask, how far should towel bar be from shower? An appropriate height to hang towel bars / racks is between 44″ – 56″ from the floor (the industry standard is 48″). My personal preference is between 44-48″.How many towel bars do you need in a bathroom?Hang two towel bars side by side if you have a large wall where you can accommodate two sets of towels. Allow about one inch in between the two bars.
