In a small bathroom especially, a light sconce will spread the light along the wall better than other types of lighting. A sconce is a very nice look around the bathtub room, next to a clawfoot bathtup and shower set up.
Sconces lend an ambiance of romance to a retro style bathroom.
If you are slowly redecorating a current bathroom, lighting is easily replaced one fixture at a time, so it is definitely a project that you can work on as you find the income to pay for the lights. Lights make a huge change of style in your bathroom with a very small amount of effort and expense, and your friends and family will notice the changes right away.
Just by changing your lighting and shower curtain, you can change the entire look of your bathroom to a retro style bathroom, whether you own a house or rent an apartment.
