Considerations for your Basement Bathroom

Plan Carefully

Think over the plan of your future bathroom carefully; find out where you want to place a bathtub, where you’ll have a shower cabin, a toilet, or a steam room. It’s wise to draw out plans for your bathroom prior to diving in. Carefully consider where you want the layout of everything, and if needed, consult a contractor if you are going the DIY route. It can’t hurt to get a professional opinion first.

Next up is plumbing, and once that is done, you can’t make any changes to the layout, so think over your layout and make sure it’s well thought out.

Insulation And Plumbing

Insulate the basement bathroom correctly otherwise, you won’t be able to go there during cold months. Do the plumbing properly; if you hesitate that you can do it, it may be wise to hire a professional.

You will also need to consider if your house is newer or older because this changes things. Typically, older homes won’t come with a rough-in. If your basement isn’t set up to include the necessary systems like drains and plumbing vents, you will need to have them added.

In the case of a drain, it means routing piping below your floor, which in most cases means breaking up a portion of your concrete to add a drain, not to mention regarding the slope so that the water actually flows into the drain. You may even need to install a special upflush toilet, depending on where your main drain line is found in the home.

An exhaust or ventilation fan is a crucial addition for basement bathrooms so that moisture can be removed.

You’ll need to install the proper vents for a basement bathroom if your home isn’t roughed in. This is going to mean cutting into concrete, drywall, and other building materials to direct that exhaust safely out of your home.

Bathroom exhaust fans are a critical part of your bathroom. They stop odors, improve indoor air quality, and terminate moisture and humidity, which can lead to structural damage, mildew, and mold growth. Bathroom vent fans are required by most local building codes for any bathroom that doesn’t have a window that can be opened. In some areas, ventilation fans are required even if your bathroom has windows.


Generally, you’ll see the tile in a bathroom- which is a good choice for your basement bathroom, but you must consider what goes under the tile. This is an important consideration that should not be overlooked.

Installing an uncoupling membrane between your concrete and your tile is important to prevent cracking. Because of temperature fluctuations, the concrete substrate expands and contracts naturally. Installing an uncoupling membrane between your concrete and your tile keeps the two materials separated so that when one moves, the other doesn’t move with it, which stops the major cause of cracks.


Space in your basement bathroom may be at a premium – so don’t waste it. Your basement ceiling may already be fairly low, so be careful when picking out your lighting fixture.

Recessed or pot lights are a great choice for a basement bathroom. These lighting choices will provide enough light without taking away valuable headroom. To add enough lighting, you can even have them installed inside the shower. But these lights have to be rated for use in a wet zone. When they’re installed correctly, with a good quality trim that resists water and vapor, it’s completely safe.

Here are some quick tips for better lighting in a basement bathroom:

  • Layering is the most suitable technique for enhancing bathroom lighting in your basement. You may rotate between bright light for cleaning and gentler levels for a pleasing ambiance, thanks to layers of light regulated by dimmers and individual circuits.
  • Consider the three main types of lighting – ambiance, accent, and task.
    • Ambiance – the room’s overall lighting
    • Accent – used to highlight a specific area
    • Task – lighting for essential daily tasks, like applying makeup, shaving, etc.
  • Used pot lights or recessed lighting so that you don’t take up any headroom in a small bathroom
  • LED Lighted mirrors or light-up medicine cabinets can add extra lighting
  • Under cabinet or strip lighting can help illuminate the floor and make the room appear brighter
  • Vertical wall sconces are a refreshing change from the traditional overhead vanity and are great for small bathrooms. They will provide a unique modern look to your bathroom, take up little space, and are best for casting an even light across the face.

Decorate Your Basement Bathroom

After the most difficult part of work is over, decide what colors you want in your basement bathroom. Decorate according to the style you’ve chosen, but when it comes to a basement, it is better to opt for some light or neutral shades because they visually enlarge your bathroom and reflect the lights.

You may try many styles for your basement bathroom: modern, minimalist, rustic, industrial, retro, farmhouse, rough stone, and so on – it’s totally up to your style and tastes. Add accents according to the style chosen: brass for retro bathrooms, pipes and industrial metal for industrial bathrooms, and rough wood and stone for nature-inspired ones.

Be creative with décor, use various materials and textures that fit your style: wood, metal, various cool tiles, and rough stone, and make a calming oasis in the basement. Find out where you’ll place the lights and attach them, don’t forget to protect them from water – it’s not only the water after taking a shower; the basement is often a bit damp.

The basement bathroom is a useful room that is often treated as a purely practical space. Often this room lacks natural light and is located out of sight of the main part of the house — given these factors, it is often overlooked. But inspirational home renovators and interior designers increasingly see this room as a decorating prospect.

Classic Subway Tile

Blogger Quinn from Quinn’s Place completely renovated the dingy, dated 70s-style basement bathroom of her 1912 house to create an updated and practical space. After a DIY gut renovation, she converted it with bright white paint, classic white subway tiles with graphic dark grout, black penny tiles on the floor and shower pan, and a clear sliding glass shower door to keep sightlines clear and produce a sense of space in the snug room. It’s a simple, neutral, attractive design that looks as good as any other bathroom in the house.

Go With a Freestanding Tub

Freestanding baths are undoubtedly one of the most attractive elements to include when designing a new bathroom. Placing the tub in the middle of the floor – and adding LED wall panels as in this example – provides a luxurious finish inspired by boutique hotels and makes bath time fun for young children.

A Dark Bold Vanity

If you want to add a dark, dramatic color but you’re afraid of making an already small space feel smaller, try just painting your vanity a dark contrasting color from the light white walls. This will give you that bold look that you are after without overpowering the space.

Frequently Asked QuestionsFAQ

How much does it cost to add a bathroom to a basement?

Adding a bathroom in a basement costs $8,000 to $15,000 on average. You'll save $500 to $1,000 if you have a rough-in drain already in place – typical in newer homes and usually near the main drain line.

Is it worth building a bathroom in the basement?

Adding a bathroom to your basement makes it a livable space, improving your home's overall market value. A bathroom in your basement can also be a huge selling point for buyers if you are ever looking to sell. When a basement is unfinished with no bathroom, buyers look at the basement as wasted space.

Do basements need special toilets?

A basement bathroom will need to have enough of a slope to drain the toilet waste to the main sewage line. However, the basement is typically below the main sewage line and will more than likely require added plumbing. The pipe size needs to be large enough to accommodate the added bathroom as well.

Does a basement bathroom need a vent?

Basement bathrooms need exhaust fans when there is a shower or a bathtub in the room. In toilets without showers, a ductless bathroom fan is an acceptable option. Although building codes allow a window for ventilation, in most cases, it is not practical.

Can I use a dehumidifier instead of a bathroom fan?

A dehumidifier is designed to collect and remove moisture, not necessarily ventilate a bathroom. Some dehumidifiers do pump in dry air, but these humidifiers are part of a greater HVAC system. A regular, portable home dehumidifier instead of a bathroom fan cannot be used.
