The prices below were correct at the time of publishing this article.
1. Overlooking ventilation
We love having a steamy shower — but all this moisture can build up pretty quickly in a small bathroom.
“Proper ventilation is essential in a small bathroom to prevent moisture buildup and mold growth,” says Nina Lichtenstein, principal designer and founder of Nina’s Home Design.
She explains, “Avoid the mistake of inadequate ventilation by installing an exhaust fan or opening windows regularly to promote air circulation.”
Good ventilation not only improves air quality but will also help maintain the condition of your beautiful fixtures and finishes.
2. Inadequate storage solutions
One big small bathroom layout mistake is not properly taking into account small bathroom storage ideas. After all, where are you going to put all your lotions and potions?
“Lack of storage is a common issue in small bathrooms, leading to cluttered countertops and limited organization,” Nina explains.
She continues, “Avoid the mistake of insufficient storage by incorporating smart solutions such as recessed shelves, wall-mounted cabinets, or over-the-toilet storage units.”
By utilizing vertical space effectively, you can maximize storage capacity without overcrowding your little room.

3. Having a bath tub
While having a bubbly bath is lovely, if you have more than one bathroom in your place or don’t need a bath, it’s a better idea to go for a larger shower.
“As long as a house has one bathtub, you’re generally fine for resale,” explains Morgan Newfield, interior designer and owner of Newfield Design, Inc.
She continues, “If you can get away without a bathtub in a small bathroom, it’s much nicer to create a luxurious shower than putting in a step-in tub shower combination.”
If you do need that tub shower combo, Morgan says to consider going without a shower door and waterproofing with tile on the surrounding walls.
We also recommend putting your extra dollars in a quality high-pressure shower head, as this will still make your small bathroom feel luxurious.

4. Neglecting accessibility
Forgetting about accessibility is a huge small bathroom layout mistake, as it can lead to major inconvenience and discomfort.
Nina says, “Avoid this mistake by ensuring that fixtures are accessible and user-friendly for all household members.”
She continues, “Consider installing grab bars, adjustable showerheads, and slip-resistant flooring for safety and ease of use.”
It’s also a good idea to grab one of the best bath mats with non-slip backing, such as the Slipx Solutions Rubber Bath Mat from Target.
5. Blocking natural light
Natural light can make a small bathroom feel brighter and more spacious, which is why preventing it from flowing through can be a big small bathroom layout mistake.
Nina says, “Avoid blocking windows or using heavy window treatments that diminish natural light.”
She explains, “Instead, embrace natural light by opting for sheer curtains or frosted glass for privacy.”
If windows are limited, Nina suggests considering installing skylights or using mirrors strategically to reflect light and visually expand the space.

6. Poor layout of fixtures
Even if your space is small, it’s still important you can walk smoothly through it without the fear of tripping over.
“Improper placement of fixtures can disrupt the flow and functionality, which is a big small bathroom layout mistake,” Nina says.
For example, she suggests avoiding placing the toilet directly next to the bathtub or shower, as this can make the space feel cramped.
“Don’t be afraid to consider alternative layouts that optimize space without sacrificing convenience,” she adds.
7. Over-designing
You may be tempted to over-decorate and attempt to compensate for what you don’t have — but this is actually a huge no-no in small bathrooms.
Morgan explains, “The biggest small bathroom mistake is trying to cram too many design elements and materials into a small space.”
She continues, “You’ll be much happier with the result if you have a singular design element to bring everything together and create a sense of space.”
Morgan recommends having a designer draw your space to integrate the various elements. Alternatively, you could always do this yourself.
By prioritizing space-saving solutions, efficient placement of fixtures, and a cohesive design approach, you can create a small bathroom that is both beautiful and practical.
“Incorporate these tips to achieve a smart layout that maximizes the potential of your small bathroom,” Nina finishes by saying.
Once you’ve got your small bathroom sorted, you might want to consider your small kitchen layout next.
