Storing bathroom towels can be a pain considering their significance and the amount of space they occupy. They need to be stored at the right place so that they are handy and accessible easily. The best place I believe is at a one arm distance near the wash basin or sink. Ideally it should be at either side of the wash basin but if the bathroom is small these can be creatively placed under or above the modern sink.
Normal inexpensive DIY open cabinets can be used for it. Also, book shelves or racks can be used for this with a little bit of tweaking here and there. Any piece of furniture which is lying idle at home can be brought into use creatively. Even a ladder can be placed by the side and can be used as bathroom towel storage. It will give a rustic and vintage look to the bathroom with towels and other toiletries on it. Placing some candles and show pieces around it can make it look more appealing.
One more way is to hang baskets on the bathroom wall and neatly put towels inside. It is always better to roll the towel to store it. It takes less space and makes it look neat and tidy. Using different colored towels in contrast with the bathroom tiles, flooring and décor will serve as the icing on the cake. Just let your creative juices flow so that you come up with crazy bathroom towel storage ideas.
