A bathroom renovation can cost anywhere between $5,000 and $25,000. If you plan on installing a new sink, toilet, tub, shower, tiles, and more in your bathroom, it could be more expensive than if you want to do simple fixes. The price for a bathroom renovation depends on how much time you take to complete the job and how many people are working on it. A small bathroom renovation can take as few as two days for one person to complete. Keep in mind that some materials need to be custom ordered and installed, so the final cost of your project will vary greatly depending on what materials you use.
