The 2014 survey for bathroom and kitchen remodeling is in.
I'm not going to bore you with lots of discussion - just the facts for all you busy folks out there.
I'll provide the question and the top answers.
The answers in blue represent the adjusted Orange County, California figures.
The national average size for a bathroom is 40-50 square feet.
The national average size for a kitchen is 70-100 square feet.
The very bottom might surprise you regarding tubs.
Remember:

• This is across all 50 states.
  
• Beautiful Orange County, California, along with the remainder of California, is super regulated and super taxed.
  Here, in general, costs typically run about 40%-60% higher than most of the nation.
  
• Once again, according to the survey, this is what you and your neighbors were doing when it comes to kitchen and bathroom remodeling during 2014.

What's the biggest change over the last several years? Tubs aren't being used anymore.
Clients are ripping out whirlpools and putting in large walk-in showers.
If they are replacing tubs, they're putting in deep soaking tubs.
I personally see this all the time and have been doing this for many years.
Clients want big, two-people, fully tiled showers with lots of amenities.
One caveat to be aware of if you are considering this option is that realtors say it is best to leave at least one bathtub in your home to protect its resale value (young families need a place to bathe the kiddies!).
