7 Tips to Help When Planning to Add a Bathroom in a Basement


Adding a bathroom to a basement is an easy do-it-yourself job. It also adds value to your home. It helps turn the basement into usable space where family members can have a get together without having to run upstairs every now and then to use the washroom facilities. You need to critically evaluate the existing space in the basement to see where the bathroom can be fitted in. You also need to decide whether you want to have just a full or a half bathroom.


Decide on a theme for the bathroom. While the bathroom is the most utilitarian room in the house, it can have a personality of its own. It can be made of bare walls or glasses. Decide on a combination of colors to be used in the bathroom.

Decide the accessories to be used as well, such as bath towels, bathroom rugs, soap dishes, and toothbrush holders. You can have a simple theme that uses colors like pale yellow, salmon pink, apple green, or sky blue. In case you have an artistic blend, you can also opt for artistic themes where bright contrasting colors are used, such as white with black, dark blue with light blue, or lavender with purple. Choose a color scheme that complements your lifestyle and should also help you relax.


Consider adding mirrors in our basement bathroom. They create the illusion of larger space and light up the area.

Fans and Lighting

Add a fan to the bathroom so that the odors and moisture can be carried away. The fan should be strong, yet quiet enough to circulate the air properly. As basements are generally dark, you should make the accommodation for sufficient lighting. Select electric fixtures that offer good lighting without any glare and reflection.


You also need a storage area for bathroom accessories like bath towels, toilet rolls, and cleaners. It can take the shape of steel towel holders, or inbuilt wooden cabinets.


While planning to add bathroom to the basement, you will also need to plan how the waste water in the bathroom should be directed upwards into the sewer tank. One available option is a macerating system. This unit has a sink, shower, and toilet with a draining unit that can be placed outside the house.

It does not require the basement floor to be dug up. The cost ranges from $800 to $1000. Another option is a sump and ejector system, which requires professional installation. It is less costly than the macerating unit. Regardless of which option you choose, make sure to check the local code requirements firs.


If you do not wish to spend money on new pipes and drains, locate the bathroom just below an existing bathroom.

Circuit Interrupter

To prevent electric shock and fires, use Ground Fault Circuit Interrupter (GFCI) outlets in the bathroom.
