Cost to Add Small Half Bathroom

Add Small Half Bathroom

It’s time to add a bathroom to your home. You want to save money on installation, though, so you’ve chosen to install a half bathroom instead of a full bathroom. While adding a small bathroom is cheaper than adding a large master bathroom, the price breakdown can still be confusing.

So, how much does it cost to add a half bathroom?

Here’s what you need to know:

How Much Does It Cost to Add a Half Bathroom?

The cost of adding a small bathroom depends on many factors.

The first is size. A half bath is typically about 3-4 feet wide, and about 6-8 feet long, and larger half baths will be more expensive than smaller half baths.  

The second consideration is amenities. Half baths generally have a toilet, sink, and a mirror, although some are tricked out with additional storage and a vanity.

The final, and largest cost of adding a half bathroom, is plumbing. Plumbing a new bathroom can run about $10,000-$25,000, especially if you have to cut through a foundation to do it. 

That said, many people choose to save money by keeping the half bath near existing plumbing (on a shared wall with another bathroom, for example) or installing a Saniflo toilet system. The latter allows you to skip adding new plumbing and convert anything from an old closet to a nook into a half bath.
