An upscale bathroom remodel can cost an average of $60,000, with about 59 percent recouped if the house is sold.

  • Can be less costly to build vs. building multiple, separate bathrooms for each bedroom.
  • Private space for kids "mess".  Not accessible to visitors, like a normal hallway bath would be.
  • Can allow for "semi-private" bathroom solution, using typically unusable space.
  • Can include multiple sinks to provide more individual space to each child.


  • Not as convenient when multiple people need to use at the same time (i.e. showers, toilet, etc)
  • Not as much privacy as with fully separate bathrooms
  • Can be difficult to make fit in certain house plans.


A Jack and Jill bathroom layout can be an excellent option for many families.

After all, since the bathroom can be locked from either side, the bedrooms and baths can remain separate and private for each person.

In addition, having a jack & jill bathroom wil help your children to learn to share and to compromise on their individual "timing" and "needs" for using the bath & toilet.

Finally, there are a few conveniences that you'll want to make sure to include:

- Two separate sinks - it goes without saying that, having 2 sinks, is always going to be better than having one. This one feature can give each person their own space for brushing their teeth, putting on makeup, combing their hair, etc. and that will help to lessen any "disagreements".

- Doors that can be locked both INSIDE and OUTSIDE - this feature is very important as you'll enable your children to truly have privacy, whether they're in their bedroom or in the bath.

At the end of the day, when you're building your very own dream home, YOU have the ability to build exactly what best fits your family!
