When we moved into this house, the first-floor bathroom was one of the first spaces I wanted to update. It’s the bathroom guests see the most, so I wanted it to make a great impression. While the bathroom wasn’t horrible, it was very basic and lacked any personality, with cheap, builder-grade fixtures that didn’t reflect my style. I knew I wanted to give it a fresh look without doing a full remodel or spending a fortune. That’s when I decided to embark on this affordable DIY bathroom makeover journey.

Replacing the Builder-Grade Mirror

One of the biggest challenges I faced was removing the large, glued-on builder-grade mirror. I learned the hard way that removing a mirror like this often leads to damage. Sure enough, I had to patch the drywall. Patching is straightforward, but it takes time and practice to get a smooth surface.

Fresh Coat of Paint: Small Bathroom Paint Ideas for No Natural Light

I changed the greige wall color to bright white, which completely brightened the space — I used “Chantilly Lace” from Benjamin Moore. The original builder-grade paint had a flat finish, which made it nearly impossible to clean.

Here’s a tip: When going from a darker color to a lighter one, always use a primer. Primers cost a fraction of the price compared to good quality paint, which means you don’t have to apply as many coats of the final paint color. I learned this the hard way, but it would have saved me both time and money if I had primed first!

Upgrading the Light Fixture

The next step was upgrading the light fixture. I decided on a modern gold fixture, which made a huge difference in the overall ambiance. Good lighting can dramatically change a room’s feel, especially one without natural light. I prefer cool lighting, so I went with these light bulbs, which made the room look even brighter. If you’re tackling a small bathroom like mine, upgrading the light fixture is a simple but effective change.

Adding New Cabinet Hardware and Towel Hook

New cabinet handles and knobs were easy yet impactful updates. I chose black hardware. For the towel hook I chose a modern brushed goal to match the faucet

Adding a Shelf Above the Toilet

One of the easiest and most effective ways to maximize storage in a small bathroom is by adding a floating shelf. I decided to install a simple wooden shelf above the toilet, which not only provided extra space for essentials like towels and toiletries but also added a decorative touch to the room.
 
For the shelf, I chose a light, natural wood finish that complements the black hardware and the neutral color palette of the bathroom. The floating design keeps the space looking clean and modern, and it was an easy DIY project that made a big impact without breaking the bank.

Replacing Baseboards

Finally, I replaced the baseboards. This might seem like a minor detail, but it’s the finishing touches that can make a room look polished and complete. The new baseboards added a clean, crisp edge to the room, further enhancing the fresh, modern look.
