A spacious, well-organized bathroom is truly life-changing.

A great bathroom should, of course, be visually pleasing, but most importantly, it should serve its purpose well: adequate storage for everything from bath products to towels, lighting that serves the tasks performed in a bathroom, and finishes that are resistant to humid environments. Avoids these errors.

Neglecting Storage: Every single designer agreed on one major mistake: not having enough storage.

โ€œYou absolutely need as much storage as possible to ensure that your bathroom stays the most functional and uncluttered space,โ€ said interior designer Tali Roth. โ€œMedicine cabinets, although often harder to find attractive ones, are so, so useful for storing all those small items for everyday use. If youโ€™re building from scratch, explore recessed wall cabinets and recessed shower shelves.โ€

The designers at Studio Life.Style suggested focusing on the vanity: โ€œMake sure to either custom make or purchase a vanity that has plenty of storage to hold things like your hair dryer and makeup.โ€

Laguna Beach, Calif.-based designer Ohara Davies-Gaetano insisted on the importance of towel storage: โ€œMake sure that you have allocated space to keep fresh towels. I always suggest having a few robe hooks placed around the bathroom instead of towel bars โ€” this allows you to have a place to dry multiple towels or robes.โ€

The designers at Massucco Warner Miller suggested getting creative with storage solutions: โ€œEven if you donโ€™t have room for a vanity with serious storage, it doesnโ€™t mean you canโ€™t sneak in some extra space elsewhere with a vintage apothecary cabinet, a train rack, or even recessed medicine cabinets for keeping toiletries out of sight.

Overlooking Lighting: The other main bathroom design offender: lighting.

โ€œThereโ€™s nothing worse than a poorly lit bathroom,โ€ said Roth. โ€œPeople often forget that they need multiple light sources and end up with a single dull sconce. Try to incorporate both decorative and task lighting.โ€

Davies-Gaetano agrees: โ€œSo often the importance of lighting is overlooked when designing a bathroom,โ€ she said. โ€œItโ€™s always preferred to make sure that a bathroom has a good source of natural light as well as strategically placed overhead and vanity light. If your bathroom suffers from poor lighting, add a table lamp, floor lamp, or chandelier.โ€

For the designers at Massucco Warner Miller, the importance is to install lighting that suits your needs: โ€œThink through the lighting to make sure it suits your needs. If you love applying meticulous makeup, itโ€™s helpful to add sconces or even a chic lit magnifying mirror. Or if you favor soothing baths, dimmable ceiling lights to create a relaxing mood would be a great choice.โ€

Choosing Too Many Finishes: Roth pointed out how messy designs can become when going crazy with finishes and patterns: โ€œMy theory is that in most circumstances, more than two finishes in a bathroom can look odd. Try to flow the materials in a digestible way โ€” keep all the floor materials the same and change up the walls. If you want a statement pattern or color, use it on the floors or tile the inside of a recessed shelf instead of putting it everywhere.โ€

Planning Electrical Too Late: For New York-based designer Jane Abercrombie, the single biggest mistake when designing a bathroom is to plan the electrical components too late. โ€œRemember, electrical planning needs to be done very early in the process,โ€ she said. โ€œFor example, a hardwired makeup mirror is great mounted on the wall, but you need to remember this in the early phase. Itโ€™s so wonderful to have outlets in drawers โ€” for hair dryers and straightening irons so they can be tucked away quickly and neatly. If you forget to do this, you can have someone cut a grommet hole in the drawer and use an extension cord from the wall outlet. This is a game changer!โ€

Choosing Slippery Tiles: โ€œA common mistake is using cool, decorative tile on their bathroom floors that arenโ€™t made for getting wet, which can make it really easy to slip on,โ€ explained the designers at Studio Life.Style. โ€œThis can be fixed by either making the flooring slip-resistant which can be done with treatments, or making sure that the tile you choose is suitable for bathrooms.โ€

Forgetting Personality: โ€œPeople forget that bathrooms can have personality just like any other room in your house,โ€ the designers at Massucco Warner Miller told us. The fix: โ€œAdd a fun and unexpected light fixture, chic art, or even wallpaper! Bathrooms are typically smaller spaces, so it doesnโ€™t take much to really spice them up and make them cohesive with the decor of the rest of the house.โ€

Not Considering Humidity: Lastly, the designers at Studio Life.Style warned against the use of wallpaper: โ€œWe can all agree that adding wallpaper to any bathroom can immediately warm up a space. We love using wallpaper in all the bathrooms we design, but the biggest thing we always keep in mind is that the wallpaper needs to either be made for bathrooms (like a vinyl, for example), or the backsplash needs to be high enough so that the wallpaper wonโ€™t get damaged.โ€
