Take a good look at your walls. If they are sound and sturdy then a slightly new look may be just what you're looking for. A new coat of paint can change the look of any room and give it the new look you're looking for. If you've got tile or porcelain in your bathroom you can buy porcelain paint at any home center for about $20. You are somewhat limited with colors as most come in white or off white but it sure makes a difference in how a pink 70's style bathroom may look before and how a white bathroom will look after. Painting your walls is easy and doesn't take a whole lot of time. You'll be surprised at what paint does to a room and this won't break your budget.

You don't have to just paint your walls to make a big change. If you have a vanity that is still in working condition then try painting it as well. You can either paint right over the wood with a color of your choice, or you can strip the wood and stain it a lighter or darker color. Updating your vanity can drastically change the appearance of your bathroom without spending a ton of money to do it.
