There are no averages and the bathroom remodeling cost might very from a few hundred dollars for simple do it yourself refreshment to couple hundred thousand for high quality custom work. There are remodelling professionals who can help in the process and get you a new style bathroom. This type of renovation may include a larger bathroom and replacing existing fixtures while keeping them in the same location. TV shows are very inaccurate in their pricing, especially for someone who lives in an expensive area like San Francisco, so I would not suggest using them as a reference point.
Note, that while the average price for an 8×5 bathroom remodel is about $7500, you can do a complete renovation for under $1000 with new sink, toilet, fixtures, and bathtub refinishing. Determine how much you can afford to spend on your remodel to determine the extent of the changes you can make.
The report also estimates that such a job will recoup 102 percent of its cost at resale. I had another client who just installed a bathroom where one did not exist previously (so they had to dig up the sidewalk/garage floor and install lines) and it was well under $30k.
Mine was really an expansion instead of a remodel, since the bathroom went from 36 square feet to roughly 170 square feet. You may also need an asbestos inspection, again depending on the building requirements and your plumbing plans, which can cost around $500.
Custom tub and shower combos with features like wall tile often cost $4,000 to $5,000, installed. If your bathroom has one or two areas of concern, you might decide to swap out an individual fixture or two. Upfront, a shower curtain is significantly less expensive than a glass door, but over time, the cost and hassle of cleaning and replacing it adds up. You can add between $350 and up to $2,000 to your renovation budget if you decide on a glass door.
