You’ll spend $3,000 to $8,000 on the typical remodel. Anywhere from 40 to 65 percent of a bath upgrade cost comes from labor. However, doing any project yourself means no insurance and added fees if something goes wrong. Hire a professional for any work you’re not comfortable doing, such as the plumbing and electrical. Consider the pros and cons of DIY vs professional bathroom remodeling.
My suggestion is when talking to contractor be subtle and ask your questions. Ask if he/she will have a dumpster or trailer to haul away debris. If the don't get dumpster or have a trailer then you probably don't want them to work on your home. Tell them your concern with the only toilet in the house. Unless it is not safe I have always reinstalled the toilet so it could be used at night. A good contractor will work with you in anyway possible because you are the key to more business.
There are so many beautiful things to notice about this bathroom that it's hard to know where to start. The concrete sink? The wallpaper? The sconce lighting? The tarnished mirror on the door, reflected in the main mirror? The barely-there ultra-modern faucets? Whatever you notice first, though, you can't but admit that this space is a masterpiece.
