Renovating a bathroom is an exciting opportunity to transform one of the most-used spaces in your home into something beautiful and functional.

But, as with any renovation project, there are plenty of things that can go wrong if you're not careful. In fact, many homeowners unknowingly make mistakes that cost them both time and money, not to mention the frustration of having to redo things.

So, are you about to make any of these costly bathroom renovation mistakes? Let’s walk through the common pitfalls together, so you can avoid them, save money, and end up with a bathroom that not only looks great but stands the test of time.

Whether it’s forgetting an exhaust fan or choosing the wrong shower head, these tips will help ensure your project runs smoothly.
‍

1. Skipping Proper Ventilation

A bathroom without proper ventilation is a recipe for disaster. Bathrooms are humid environments where moisture can build up quickly, leading to mold, mildew, and even damage to your walls and ceilings.

Installing a quality exhaust fan is crucial to prevent all these issues. It not only helps to remove humidity but also reduces odors and makes the space feel fresher.

💡 Pro Tip: Make sure you choose an exhaust fan that’s sized appropriately for your bathroom. A fan that’s too small won’t do the job, and one that’s too big could be overkill and unnecessarily expensive. Also, don’t forget to clean it regularly—dust and grime can reduce its efficiency over time.

2. Ignoring the Power of Lighting

‍

Lighting might seem like an afterthought, but it’s one of the most important factors in a successful bathroom design. Poor lighting can make a bathroom feel dark, cramped, and uninviting. On the other hand, a well-lit bathroom is not only more functional but also feels more spacious and inviting.

When planning your bathroom renovation, think about layering your light fixtures. Use a combination of overhead lighting, vanity lights, and task lighting to create a warm and bright environment. Natural light is ideal, so if you have a window, maximize the amount of light coming in.

However, if your powder room or bathroom doesn’t have a window, recessed lighting or strategically placed mirrors can help bounce light around the space.

💡 Pro Tip: Consider adding a dimmer switch for your light fixtures. This will allow you to adjust the lighting based on your needs—bright for getting ready in the morning and dim for a relaxing soak in the soaking tub at night.
‍

3. Choosing the Wrong Floor Tile

Bathroom tile selection is more important than you might think. Not all tiles are created equal, and some materials are simply not suited to withstand the moisture and humidity in a bathroom. Floor tile needs to be slip-resistant and durable to handle high foot traffic and water spills.

Tiles like ceramic, porcelain, and natural stone are great choices for bathrooms because they are durable and water-resistant. Steer clear of tiles that can become slippery when wet or those that stain easily.

💡 Pro Tip: If you're leaning toward natural stone tiles, remember they need to be sealed regularly to prevent water damage. Also, when choosing the color palette for your tiles, consider how it fits with the rest of your bathroom design and contributes to the overall aesthetic.

4. Underestimating Storage Space

Storage is an element that many people overlook when they’re caught up in the excitement of a bathroom renovation. But lack of storage can lead to clutter, which will make even the most beautifully designed bathroom feel chaotic and disorganized. Proper storage space is essential, not just for keeping the bathroom tidy, but for making the room more functional and enjoyable to use.

Think about where you’ll store your towels, toiletries, and cleaning supplies. Consider built-in shelving, shower niches, vanity cabinets, and even floating shelves as creative ways to maximize storage without compromising style. Shower niches are especially useful for keeping products off the floor and out of the way while still being easily accessible.

💡 Pro Tip: Don't forget about vertical storage! Use the height of your bathroom by installing tall cabinets or adding shelving above the toilet. You can even make use of empty wall space by incorporating hooks or small baskets to store essentials.
‍

5. Opting for the Wrong Shower Head

A shower head might seem like a small detail, but it can have a huge impact on both your daily experience and your water bill. Choosing the right shower head can enhance your showers, providing a spa-like feel, while also conserving water.

There are plenty of options, from rainfall showers to handheld sprayers. While a rainfall showerhead adds luxury, a handheld shower can be more versatile for cleaning and washing. Just make sure whichever option you go with suits your lifestyle and your bathroom's shower walls.

💡 Pro Tip: Look for eco-friendly shower heads that provide strong water pressure but use less water. This will help you save money on your water bill without sacrificing comfort.
‍

6. Neglecting Proper Drainage in the Shower

If you’re considering a curbless shower, ensuring proper drainage is even more critical since water can more easily escape onto the bathroom floor. Work with your contractor to make sure that the shower floor has the correct slope toward the drain to prevent water from pooling.

Additionally, make sure that the floor tile is slip-resistant, especially if you're opting for a curbless shower, where water can flow more freely across the bathroom floor.

💡 Pro Tip: If you're unsure about the right shower layout or drainage system, consult with an experienced interior design professional or contractor. They can help you achieve the sleek look of a curbless shower while ensuring that functionality isn’t compromised.

7. Skimping on Storage for Cleaning Supplies

Bathrooms need regular cleaning, but if you don’t have dedicated storage for your cleaning supplies, you’ll end up with clutter. Many homeowners focus on designing a beautiful bathroom and forget to allocate space for the practical aspects like storage for their cleaning supplies.

It’s a good idea to incorporate hidden storage solutions, such as pull-out drawers or cabinets under the sink, where you can easily store your bathroom cleaners, sponges, and other necessities. This will keep the bathroom looking tidy without having cleaning products in plain sight.

💡 Pro Tip: Consider adding a small closet or a tall, narrow cabinet next to your vanity or behind the door to house all your cleaning supplies. This helps keep the bathroom free of clutter and makes it easier to clean and maintain.

8. Overlooking Accent Lighting and Design Features

Many homeowners focus on the practical aspects of a bathroom renovation and forget about the fun part—creating a beautiful, personalized space. An easy way to add style to your bathroom is with an accent wall, eye-catching light fixtures, or even unique vanity mirrors.

Accent walls with bold patterns or textures can instantly elevate the look of the room without breaking the bank.

Also, think about adding elegant light fixtures like pendant lights or wall sconces. These small touches can give your bathroom a luxurious, spa-like feel and highlight your bathroom's best features, like a statement bathtub or unique vintage furniture pieces.

💡 Pro Tip: If you’re working with a smaller bathroom or powder room, don’t shy away from incorporating bold colors or unique light fixtures to make the space pop. A dramatic accent wall or statement lighting can transform even a small space into a design focal point.

9. Not Thinking Long-Term for Resale Value

While designing your dream bathroom, it’s easy to get caught up in personal preferences, but remember to think about how your choices will affect your home’s real estate value down the road. Overly trendy designs may go out of style and could turn off potential buyers if you decide to sell your home in the future.

Stick to timeless elements, like neutral color schemes and classic materials. You can always add personal touches through accessories like towels, rugs, and wall art, but the bones of the bathroom should remain neutral enough to appeal to a broader audience.

💡Pro Tip: When choosing fixtures and finishes, think about what will still look good in 5-10 years. Neutral floor tile, high-quality materials, and classic fixtures will increase your home’s value and make it more attractive to future buyers.

10. Failing to Plan for Adequate Storage in the Shower

‍

It might seem like a small detail, but shower niches are a must-have for any modern bathroom renovation. Without them, you’ll be balancing your shampoo bottles on the edge of the tub or shower bench—not an ideal situation! Shower niches offer a sleek, built-in solution for storing all your bathing products, keeping them neatly organized and within arm's reach.

If more than one person will be using the shower, think about creating many shower niches to hold all of your belongings. To guarantee that niches are appropriately incorporated into the shower walls and blend in with the overall aesthetic of your bathroom, plan for them early in the design process.

💡 Pro Tip: Coordinate your shower niche tile with the rest of your bathroom tile for a cohesive look. You can also use the niche as a design feature by choosing a contrasting tile to make it stand out.
