Building The Best Basement Bathroom: Everything You Need To Know

If you’re like most people, you probably don’t want to run up and down the stairs, every time nature calls. That’s why adding a basement bathroom is such a great idea! Not only does it make your life easier, but it also can increase your property value.

However, before you start any basement bathroom remodeling project, there are a few things you need to know. In this article, we’ll discuss basement bathroom ideas that you can use to build the perfect one for your home!

Let’s get to it!

One of the first things you need to consider when adding a basement bathroom is how much space you can work with.

For example, suppose your basement is small and has low ceilings. In that case, you can install a smaller bathtub next to the vanity and the toilet seat to cover your basic needs.

However, let’s assume the ceiling is tall enough and there’s plenty of space to design. In this case, you may add an extra-large shower or jacuzzi tub for your after-workout relaxation time.

Basement Bathrooms - Design And Functionality

The design and functionality of your basement bathroom will largely depend on its layout. If it’s unfinished, you’ll likely have more flexibility regarding what types of fixtures and finishes you can use.

Be sure to keep in mind the needs of everyone who uses the basement bathroom when you rough in the design.

For example, suppose your new bathroom will be used by family members who are elderly or disabled. That’s why you’ll want to make sure it has plenty of space for walkers and wheelchairs.

Besides that, you need to decide which features are essential for your basement bathroom design:


If you’re looking for a touch of luxury in your basement bathroom, a bathtub is a great option worth considering.

You can choose one with jets or install it as part of a shower stall to save space. They’re perfect for people who like to take long baths, and they can provide a spa-like experience in the comfort of your own home!

The basement bathtubs can be made of different materials, including acrylic or fiberglass with fixtures that complement your basement’s décor.

If you’re an active person and you’re doing workouts every morning in your own home gym, adding a shower to your basement is the most convenient option.

If we talk about design, you also have quite a few choices for your basement bathroom shower:

Whatever your choices are, make sure they fit your taste and lifestyle to the very last detail.

Sink Options

If you have limited space in your basement, a single sink is your best option. However, that doesn’t mean that you have to limit your options for design.

Whether you go for a natural stone vessel sink, a decorated pedestal sink, or an undermount one, you can definitely find something that fits your taste and personality.

Depending on the basement bathroom layout you choose, your countertop and vanity may be the first things people see when they enter.

Countertops come in a variety of materials and finishes, including:

Basement bathrooms usually have wall-to-wall cabinets that store towels and other necessities like toiletries or medicine. However, if there’s only enough space to install a sink in your bathroom, consider adding an antique cabinet or dresser to use as your vanity.

Not only will it give you more storage space, but it’ll also add a unique and interesting design element to your home that no one else will have.

On the other hand, if the space is large enough, you may want to install a custom vanity. This will give you plenty of options when it comes to design, size, and even the number of sinks you want in your basement bathroom.

Basement bathrooms are often small and windowless, so proper lighting is vital for safety and comfort.

Add several light fixtures for different tasks and extra functionality:

Storage space

One of the biggest challenges in basement bathrooms is finding storage space for all your toiletries. Especially if your basement ceiling is lower than in other parts of the house.

That’s why it can be tough to find a convenient space to keep your shampoo and conditioner bottles, shaving cream tubes, and toothbrushes. Not to mention anything too big for a drawer or cabinet.

Some basement bathroom design ideas include:

The key is to make sure you have plenty of room for everything without overcrowding your basement bathroom.

Basement Floor And Bathroom Walls Tile

If your basement is damp or has any water penetrating the foundation, that must be fixed first! Covering moisture problems will make them worse once mold and mildew begin to grow. Waterproof or water resistant flooring and wall coverings will only make your water problems worse.

Since basements tend to be often damp, your basement floor needs to be water-resistant and easy to clean. Luxury, vinyl tile, and carpet are excellent options. Any of them will transform the cold concrete floor into a beautiful surface you’re happy to walk on barefoot.

When it comes to wall tiles, basement bathrooms usually have a more practical purpose than upstairs bathrooms. However, that doesn’t mean you can’t add some personality with attractive designs or colors. Just be sure to choose something that won’t get too dark once installed, as basement bathrooms tend not to get much natural light.

Basement Toilet And Ventilation System

Basement toilets require no special consideration, and can match whatever style you have in the rest of your home. Like the rest of your home, your basement bathroom must be ventilated to the exterior of the home. This is a simple task that any remodeling contractor should be able to do.

Bathroom Installation

Adding a bathroom to your basement can be a difficult and expensive project, so it’s best to leave it to the professionals.
