Here we share a step-by-step guide on how to turn a closet into a bathroom, including the cost of converting from closet to bathroom so that you have more of a functional living space that you can enjoy.

If the cabinets become more functional bathrooms, it makes sense for the homeowner who wants to improve their living space. For many families, having more bathrooms is better than having too many closets in the house.
While the cost of converting a closet into a bathroom can cost thousands of dollars, its ability to increase a property’s resale value more than outweighs any cost issues.

So how do you turn a closet into a bathroom? Let’s find out.

Steps to convert from closet to bathroom

Average DIY is not the same as turning cabinets into functional bathrooms. There are many complex steps involved and the special tools and materials required to complete the project, from cabinet prep to finishing touches.
However, if one decides to embark on a project that is worthwhile and appreciated by the whole family, there is nothing better than transforming a closet into an elegant and functional bathroom.

The process includes the following steps.

Step 1. Measure the closet space

Measure the width, height, and length of the closet, including the surrounding floor space. It is advisable to imagine a larger bathroom to make it more functional for the family.
For example, closet walls can be extended into adjoining living spaces, such as a bedroom or kitchen. See walk-in closet dimensions for more ideas.

Step 2. Make a rough draft of the closet conversion.
Use the measurements to draw or sketch a floor plan for the bathroom. Adjoining floor space should always be included in floor planning to get a good idea of ​​how the various elements of the bathroom will fit together.

It is also advisable to consult the plan of the house, noting the load-bearing capacities of the perimeter walls. They may need to be reinforced if they cannot support the normal parts of the bathroom. Read more about the best bathroom designs and design ideas here.
The floor plan should provide adequate bathroom space with many arrangements for framing the walls with 2 × 4-inch boards.

Step 3. Obtain building permits
Changing a closet to a bathroom is not the same as building a new one, not the cost. Homeowners planning to create a bathroom from a closet must adhere to local building codes and guidelines.

Of particular importance is the installation of electrical and plumbing systems, which have their respective guidelines that all builders and renovators must adhere to.

It will be wise to anticipate any installation challenges, including the distance to the house’s water supply lines and the electrical circuit panel. Homeowners should think of alternatives to their preferred methods. Some incidents will not be affected.

With a clear plan, homeowners can obtain a building permit to begin the closet-to-bathroom conversion project.

Step 4. Frame the bathroom space

After obtaining a building permit, the owner can begin to install frames. This part of the process forms the foundation of the bathroom, allowing homeowners to add various items later in the project.
Adding a skylight to a skylight should be considered, especially if the space does not have external walls. The bathroom door should match or complement the doors to adjoining rooms to ensure a more cohesive look.

Step 5. Installation of electrical and plumbing systems.
It is advisable to hire a licensed plumber and electrician if the owner is unsure of working with electrical and plumbing systems.

Making cable connections can be a simple process. However, there are many factors that must be considered when working with electrical systems.

Ideally, one would want to install the plumbing and electrical systems before the walls are finished. It includes the installation of toilet drains, shower systems, bathtubs (if any), water pipes, electrical wiring, and electrical outlets.

Experts recommend installing the toilet with only the finished bathroom floor. Also, all plumbing and water fixtures must be in place before installing any electrical system.

Step 6. Complete the floor.

Install proper bathroom floor materials after plumbing and electrical system installation. Tiles must have the proper sealer and grout. It is also recommended to install base material in the finish of the tile floor. Check out our gallery of gorgeous bathroom tile ideas here.
Install the toilet and apply a wax seal to the surface of the tile floor. However, the grout must be completely dry before proceeding to this stage.

Step 7. Add shelves and other bathroom items.
Complete the closet transformation through shelves, a small cabinet, and other items the homeowner may need in the bathroom.

It is best to consult the construction plan to find out what other components are missing. An extra touch can always be added to make the bathroom functional and aesthetically pleasing.

Cost of turning a closet into a bathroom

Converting a closet into a bathroom can cost a family between $ 5,000 and $ 20,000, depending on the size and length of the closet for the drains and plumbing systems.
It may seem expensive, but it should be understood that adding a new bathroom may cost more. You can expect to pay $ 400 to $ 600 per square foot. So it can cost anywhere from $ 19,200 to $ 28,800 if a standard 48-square-foot bathroom is added.

If there is already space, such as a closet, the cost is less than just $ 200 to $ 250 per square foot. If one has a 30-square-foot closet for bathroom conversion, the project cost can be expected to range from $ 6,000 to $ 7,500.

Cost of turning a closet into a half bathroom

Most half baths are six to eight feet long and three to four feet wide for an area of ​​18 to 32 square feet.
Knowing that a closet conversion can cost between $ 200 and $ 250 per square foot, it can be expected to cost between $ 3,600 and $ 8,000 for a half bathroom.

Converting cabinets is an even more practical option than adding a new half bath, which costs between $ 7,200 and $ 19,200 for the home.


Families who convert a closet into their bathroom will find the project more profitable than building a new one. Families can save thousands of dollars by converting their rarely used or unused closets into functional spaces the whole family can enjoy.

While the project can be completed by ordinary homeowners, it would be more efficient and effective if the transformation were handled by a professional contractor. It may come at a higher cost, but the results will be more amazing than any ordinary person can achieve.
