The addition of open shelves should be considered a must for any bathroom remodeling, especially in the case of a small bathroom where there is not so much space available to keep the necessary stuff how can a person add décor items? Open racks allow creating space for keeping things you won't find space for otherwise.
Making and placing an open shelf into your bathroom isn't a difficult task. You can even use leftover wood from the wooden frame you made for your mirror. Just cut the wooden planks according to their respective size and use metal holders to place them on the wall.
You can design the wooden planks with paint or just use a wood stain to enhance the beauty of it, finish the shelve with a beautiful wood polish to give it a nice finish. 
The open shelves will provide extra space to keep your accessories and extra bathroom décor items and will also give your bathroom an earthy feel.

Painting is the best way to create a new look and is the most affordable thing to do. The color and lighting have a big impact on how the space feels, dark and bold colors with no natural light will make your bathroom extra claustrophobic.
The best colors for a bathroom are light and brighter colors, and the greatest choice is white color, all the professional designers advise using white color for the bathroom walls.
You can create patterns and designs using paint as tiles are costly, if you are good at drawing patterns then you should give painting go. 
Painting Cabinets, instead of changing the whole drawers or cabinets just for the sake of a new design or color, you can simply paint the doors to match the color scheme. People presume that painting existing cabinets is hard as the paint won’t stuck to it, if this thing happens to you just keep in mind that you are not following the exact procedure.

For Mason Jars, you can cut a small hole in hole in the cap to allow the bulb bottom to pass through the cap and connect it with the electric holder, place the cap along with the bulb back on the mason jar and tighten it, remember to use lightweight mason jars so that they won't fall off the light fixture.
Or you can simply just place some battery-powered fairy lights inside a glass jar and place them on the open shelves for an aesthetic effect.
For stainless steel cans, cut a small opening for the bulb bottom and poke round holes big enough so that light can pass through them, keep the size according to your bulb size. This will create a warm light effect and can be turned on while having a relaxing bath.
