If you have ever stayed at a Hilton or Marriot hotel, chances are you have used a modular bathroom without even knowing it. That's because these modular structures are more cost-effective and resource-conserving than their traditional counterparts. 

Modular home designers and developers work together to build your dream house to meet your exact specifications. If you are purchasing a modular home and working with contractors during the design process, you'll want some tips to help you get exactly what you want. 

According to real estate experts, bathrooms and kitchens are the most used (and most essential) rooms in the house. For that reason, you should look at these tips on building the modular bathroom that's right for you.


Key Takeaways:

  • Create a design plan before meeting with the architect. That way, you can determine what layout will work best for you. You can get ideas from magazines and design websites.
  • Verify the amount of space you will have to work with and ensure that all features, fixtures, and fittings will fit within the space as needed.
  • Consider space-saving features like a wall-hung toilet or urinal system. Do this whether or not space is an issue.
  • Small windows or skylights will help open up the space, making small bathrooms appear larger. They can also offer natural ventilation versus an exhaust fan in your bathroom.
  • Choose fixtures that are as sustainable and eco-friendly as your modular home. Durable and environmentally conscious fittings will optimize the sustainability of your modular designs.

5 Tips on Building a Modular Bathroom 

Experts speculate the market for modular bathroom pods will continue to increase over the next six years. These bathroom pods are incredibly versatile. 

For example, designers can use these pods in public places like parks or as an addition to existing structures. They can even use these pods in a non-modular construction. 

The compound annual growth rate (CAGR) for modular bathroom pods will grow at 5.7%. That will cause the market to grow to nearly $1.2 billion by 2027.

If you are looking for some guidance on building a modular bathroom, these five tips will help get you started in designing the space you've always wanted.

1. Create a Design Plan 

A bathroom must be a comfortable space that is easy to use, relaxing, and functional. If you want to design a bathroom that suits your needs, you must pay careful attention to every detail. 

A bathroom design plan will ensure that you utilize every square inch to maximize the functionality of the room. Determine the layout of the space and what fixtures you want to have in the room. 

For example, do you want a tub with a separate shower? If so, is there space for that? Do you want a double vanity? These are things you can answer once you have a layout in mind. 

Here are a few tips for developing a design plan:

  • Look through design websites and magazines for ideas
  • Utilize an online room planner
  • Sketch out your bathroom plan on paper (or with a CAD program)
  • Consult with your contractor for insights

Design wet and dry zones in the bathroom. Separate these spaces by placing the shower, toilet, and sink in the same area of the room. If possible, consider placing the toilet behind a wall for privacy. 

2. Verify All Spacing 

Confirm that you have the space you need for clearance of doors, drawers, and cabinets. Bathroom doors are generally 28 to 36 inches wide. Leave enough room so that the door won't hit the sink or vanity. 

Ensure that when the door is open it doesn't obstruct the function of a drawer. Nothing is more annoying than stepping into the bathroom to brush your teeth and not being able to open the toothpaste drawer because the door obstructs it when open. 

If you have a smaller space, consider installing a pocket door. A barn door style is another alternative to a traditional swinging door. These types of doors will help you avoid these issues. 

3. Opt for In-Wall Cisterns 

Wall-hung toilets with in-wall cisterns are an excellent way to conserve space. They are also more aesthetically pleasing and easier to clean. 

Pair it with a dual flush actuator and a low-flow toilet. These sustainable bathroom fixtures will ensure that you get the most out of the energy efficiency of your modular home construction. 

4. Incorporate Small Windows 

Installing a small window or a skylight will make the space feel more open. It will make a smaller bathroom feel more open and add natural lighting, even if space isn't an issue. 

Preserving resources is a key feature of modular construction. Windows are another way to get natural ventilation versus using an exhaust fan to reduce odor and condensation in your bathroom. 

5. Select the Best Fixtures

Sustainability is a significant advantage to choosing modular homes. Installing water-saving fixtures will help you remain energy efficient and eco-friendly. 

Bathroom fixtures like programmable touchless faucets allow you to monitor water usage and control water flow. Set the sink to shut off after reaching the programmed amount and reduce the flow rate. You can even set the temperature to ensure energy conservation.

Other sustainable bathroom fixtures to consider incorporating in your energy-efficient modular bathroom design include:

  • Linear shower drains 
  • Low-flow showerheads 
  • Faucet aerators 
  • Dual flush actuators
