Costs of bathrooms and kitchens in new home construction

[Cailan Knight]

Hello! I've been trying to find an answer to my question for a couple weeks now and no home builders in my area have really been helpful at all! It's for a course I'm taking.

I am trying to determine what portion of new home construction(or condo construction) costs are for kitchen and baths. I've determined that the cost per Sq.Ft in my area for new home construction is anywhere between $80-$340 depending on quality. No one can tell me the percentage of that cost that would be for kitchens and bathrooms! 

So, can anyone with experience in this give me a ROUGH estimate. I don't need exact figures by any means, just a rough idea. I'm aware that prices are different all over as well.

If it costs you $100,000 to construct your average house...How much of that will be for kitchens and bathrooms?

Thanks so much to whoever can help me with this!

It depends on your exits and what is selling in your market.  Plumbing for one of our projects is about 6% of the total budget.  Most of that is in the plumbing rough and set out.  My single family home plumbing budget is about $10,000 to $11,000.  The total cost of the last single family home I did was $172,000.  Of that $11,000 budget, about $3,000 was fixtures which is what sells the house.  I could have spent $8,000 on fixtures, just as much as the rough, but that would have been for a much higher end house.  The fixed cost of your plumbing rough is going to be based on the size of the house and the number of bathrooms.  The shiny bits should be dialed in based on the market you are selling to.

Instead of speaking to builders, talk to plumbers that do new construction, and the go shopping for fixtures.
