How Much Does It Cost to Add a Bathroom?

After you add a bathroom to your home, it will increase its value by approximately 67% on the west coast of the US. On the east coast, you can get up to a 47% better price for the house with the bathroom, on average.

However, these percentages may vary significantly, which will depend on the quality of the materials, size of the bathroom itself, and the State where you live. Building a new bathroom is expensive, so adding it somewhere in your house is a more affordable option. Let’s see how much does it cost to add a bathroom.

Before You Start

After checking overall costs, you will see that you may need from $3,000 to 5,000 for a simple installing of the bathroom when you have free space at your disposal. On the other hand, the national average costs for a brand-new bathroom of 100 sq. ft (9 m2) is about $75,000. So, be careful and do your math on time.

For you, the best option is to pick an existing room in the house and make a bathroom there. It can be a basement or bigger closet if you have access to plumbing and electrical installations. In such a case, you should prepare about $3,000.

If that space is without plumbing, the overall cost will be at least $15,000. With $25,000, you can add the bathroom anywhere in the house. That costs include electrical and plumbing work, as well as all bathroom elements necessary.

You can add two types of bathrooms in your house:

  • A full bath – It includes all pieces necessary, such as a toilet, sink, and shower or bathtub. This option will add more value to your home.
  • A half-bath – It includes a toilet and sink. Since it is a cheaper option, you should choose it when your budget is limited. The average dimensions of this room include the width of at least 3 to 4 feet (0.9 – 1.2 m) and length of 6 to 8 feet (1.8 – 2,4 m).

Keep in mind that you can increase the value of your home by at least 20% once you convert a half-bath to a full bath.

Bathroom Addition Cost Factors

How much does it cost to add a bathroom will depend on many variables, including:

  1. Location – As I have already mentioned, the final costs will primarily depend on existing plumbing. You will need to pay extra for bringing vents, plumbing, and waste lines to the chosen space.
  2. Date of construction of the house – You should check the condition of the plumbing and electrical work in your home before you start working, especially if you live in an old house. Be prepared that this will affect the overall costs significantly.

  4. Unexpecting expenses – You should always count on unpleasant surprises once you start working. It can be anything, including water leaking, pests, mold, or asbestos.

Shower or Bathtub Installation Cost

Both a shower and bathtub are the central parts of every bathroom. The amount of money you have to set aside for it will depend on:

Location and weight

You need to determine the exact place for your new tub or shower and its dimensions. Check if the floor can support the total weight of a bathtub and the heaviest member of your household to prevent possible damage and injuries.

Style

It won’t be the same if you pick out the ordinary tub or top-notch shower cabin. Be prepared to choose the best option that fits your budget.

Amenities

If you can spend more money and want to enjoy a massaging, you should purchase a tub or shower with all-over body jets. Also, you can find models with lighting, built-in seating, handles, shampoo holders, stereos, and addition for aromatherapy.
