Here are several basic steps for converting a laundry room to a bathroom.

Designing the Bathroom Space

Prior to beginning the conversion of a laundry room into a bathroom, one must engage in detailed planning and design to ensure that the new space is not only aesthetically pleasing but also functional and compliant with local building codes.

A thoughtful design and layout plan is essential for a seamless conversion. The layout should be practical, combining efficient use of space with bathroom type preferences, be it a full bath or a half bath. This includes the location of the sink, toilet, shower, or tub, factoring in the necessity for privacy and ease of movement within the space.

When designing, one should determine appropriate flooring materials that are both water-resistant and durable. Proper lighting, possibly including windows for natural light, and adequate ventilation are critical for creating a comfortable and mold-free environment. Lastly, securing the necessary permits and ensuring adherence to building codes play a fundamental role in the planning stage to avoid future legal and safety issues.

Determine the Layout For Your Shower, Sink, and Toilet

The initial step involves evaluating the room size and existing layout. It is crucial to measure the space accurately to determine if it can accommodate typical bathroom fixtures such as a sink, toilet, and shower.

Additionally, one must consider if the washer and dryer can be relocated or if they must remain integrated within the design. Attention to existing electrical wiring, plumbing, and ventilation systems will impact the ease of transition and potential construction costs.

You will have to drill holes for additional water lines and drainage pipes; nevertheless, some of these features might currently operate in your laundry space. But if there are not enough water lines for the bathroom you are planning to build, then make sure to do this step.

Place your bathing area (whether you are using a bathtub or shower) in the most visible place so that it will be the first thing you see whenever you open the bathroom door.

Bathtubs are now regarded as both aesthetic and useful, so use the bath as a focal point. Alternatively, place the toilet in an unobtrusive location while considering water pipe management,’

When determining where to place your bathroom fixtures, the best advice is to consider how they will be utilized and in what arrangement. With this in mind, we would normally recommend placing the sink or vanity near the entrance, as it is frequently the last point in most bathroom practices.

The toilet and other fixtures can be moved quite far into the bathroom. This not only gives you more isolation, but it also saves you from having to walk over puddles created by individuals getting out of the shower or bathtub.

Replace or Remove Things to Maximize and Clear Out the Space

Simply eliminating some objects from the space prevents the need to buy completely new ones, saving money and time. Make sure to remove all the things in your laundry room that are not needed for a functional bathroom. In this way, you can maximize your bathroom space.

You can also invest in higher-quality things than you had previously because they will be on display more frequently once this conversion is finished. However, do not feel forced to make excessive modifications if it goes beyond your finances.

If you wish to construct new shelves and cabinets for a laundry-room-to-bathroom transition, you must know that this is not always necessary. This is because the majority of the objects needed in your bathroom are already available in your existing laundry room.

Plumbing and Electrical Work

Meticulous planning is required to map out the plumbing work necessary for bathroom features such as toilets, sinks, and shower stalls. Water lines and discharge pipes must be installed or rerouted with attention to ensure compliance with building codes.

The electrical work must cater to lighting, fixtures, and appliances, potentially requiring additional circuits. Hiring a contractor is advisable due to the complexity of this stage, which can influence labor costs.


  • Install new supply line and discharge pipes for bathroom fixtures.
  • Ensure all plumbing complies with local regulations and standards.


  • Upgrade wiring and outlets for bathroom appliances and lighting.
  • Include GFCI outlets for safety in wet areas.

Construction and Installation

After plumbing and electrical foundations are laid, structural work may commence, including framing and installing drywall. Installation of the shower stall, cabinets, and countertops requires precision to optimize the aesthetics and functionality of the space. The choice of materials will greatly affect both cost and durability.


  • Reinforce any structural elements if needed.
  • Install drywall and prepare surfaces for finishing.


  • Fit bathroom fixtures such as the shower, toilet, sink, and cabinets.
  • Install efficient storage solutions.

Apply Proper Ventilation

If your laundry room is currently located on an exterior wall within your home, then it should have an adequately sized window when converting that area into a bathroom. Homeowners are likelier to spend time in the bathroom than in the laundry room. Hence, sufficient ventilation is a must.

Mold becomes more of an issue in bathrooms owing to their wet environments, so you must account for more ventilation than it was before. Bathrooms, after all, are more prone to mold and algae growth than laundry rooms since they are in persistent contact with water.

Install Some Lights

Lighting is one of the most critical aspects to consider when transitioning your laundry room into a bathroom. If you remove all of your current light fixtures and, therefore, do not add extra lights, the illumination in the space will not be sufficient.

This would not be a problem, though, if you have other major bathrooms in your house. Meanwhile, if you intend to use this converted bathroom every day or use it with others who may not like the lack of lighting, you will need to add several lighting fixtures. 

But, if your current laundry room already has enough light fixtures, then all you have to do is reposition them to ensure that the toilet, shower, and sink areas are all sufficiently illuminated.

Install Windows

Think about putting in modern glass block windows instead of ordinary ones here to allow more light in and improve sight. Nonetheless, if your laundry room lacks a window and you prefer to ensure that the space receives adequate ventilation after this conversion, consider installing a compact exhaust fan. Do not fret, as it is inexpensive and simple to install.

Finishing Details

The last phase encompasses adding finishing details that turn a functional space into a comfortable and inviting bathroom. This stage involves painting, tiling, and accessorizing with bathroom features like mirrors and towel racks. Attention to additional costs for aesthetic choices can accumulate, impacting overall bathroom costs.

Paint and Decor

  • Apply moisture-resistant paint.
  • Add tiles, trims, and other decorative elements.

Accessories and Features

  • Install mirrors, towel holders, and other bathroom accessories.
  • Ensure adequate storage solutions are in place for a clutter-free environment.

Tips for Converting a Laundry to a Bathroom

The very first task in figuring out how to turn your laundry room into a bathroom is to redesign the space. Make a ground layout of the room and carefully think about where you will put your sink, toilet, bathtub, or shower. Go to our guide to bathroom layouts here.

Aside from that, consider your cabinet and storage area as well. Consider if you’ll install a huge vanity with shelves and cabinet space underneath your sink, or whether you’ll install an over-the-commode wet bar.

Contractor installing bathroom fixtures

After planning the design of your bathroom, try to look for fixtures that will complement both the décor you’re going for and the area allocated.

Take the dryer and washer out of the room. Employ the services of your plumber and electrician to make the necessary changes. Afterward, you may hire contractors to place your fixtures or do it yourself.

In a bathroom, effective waterproofing is critical. According to professionals, you can install liquid or sheet barriers behind your shower sidewalls to guarantee that it is waterproof, specifically if it is a tiled installation.

Furthermore, if you are replacing the subfloor of your bathroom throughout your remodeling, you will have to thoroughly waterproof it – how you perform this will differ based on the type of floor you select; hence study the manufacturer’s directions for the flooring you pick before you set it up.

Converting Laundry to Bathroom Cost

The cost of converting your laundry room to a bathroom is primarily determined by the amenities incorporated in your new bathroom. It might be approximately around $5,000 to $15,000.

A conventional bathroom will cost you roughly $5,000; anything more exquisite with heated floors and fancy tiling will cost you close to or more than that.

Laundry to Bathroom Renovation Considerations

Separate outlets for washing machines and dryers are available in laundry rooms, but you will not need them in your new bathroom. It is recommended to speak with a qualified electrician about replacing these outlets with regular GFCI outlets in your bathroom.

Keep in mind that outlets and switches must be kept at a proper distance from your shower or bathtub.

If you are converting a laundry room into a bathroom, you will need to update the plumbing. A hot and cold supply pipe, as well as a discharge pipe, would have been required for your previous washer.

These source pipes will be required in your new bathroom, but you will need to lengthen them to supply your sink, bathtub or shower, and toilet. 

If you have enough experience in plumbing, you may be able to complete such activities on your own. Nevertheless, specifically, if you’ll be changing the electrical configuration of the area, it is best to seek the advice of a licensed plumber before starting.

Your electrician and plumber can also tell you if you need a construction permit for your operation in your local municipality. If you do, make sure to plan everything out before you start your project.
