The Powder Room Beginnings & Vision

The powder room is that compact space reserved for guests, and I’ve always loved the idea of a dedicated guest bathroom. In our previous house, guests used one of the kids’ bathrooms, which was always a challenge to keep tidy. The powder room is the perfect spot to be playful and bold—where a home can wear a disco ball instead of a neutral palette. It should feel like an unexpected jewel box that delights visitors and gives you permission to step out of your comfort zone.

For this design I planned to bring color through both paint and wallpaper, add warm brass finishes and introduce texture. I wanted the moment someone opened the door to feel like a mini escape—fresh, fun and a little unexpected. Below is the design board that guided the makeover:

Everything I added to the room is décor—no major demolition or plumbing changes. It was all DIY: paint, trim, wallpaper and new hardware. The biggest challenges were cutting and installing the picture frame moulding, hanging wallpaper around fixtures, and removing and reinstalling the light to paper behind it. It was time-consuming, but well worth the effort.

Here is where the room started when we bought the house: yellow walls, an outdated light, a horizontal mirror and a couple of basic accessories.

After moving in, I briefly painted the room Edgecomb Gray to match the hallway and swapped a few fixtures. It was a holding pattern until I could complete the full makeover.

And now—this view has been completely transformed.

It’s amazing how paint, trim, wallpaper and updated hardware can elevate a small room. The powder room is a place to be bold, and I’m so glad I embraced it.

DIY Powder Room Decor & Changes

Here’s a breakdown of the main changes and choices that shaped the finished space.

The transformation began with picture frame moulding. I documented the planning and installation in a DIY tutorial because it was the most time-consuming part and it dramatically changed the room’s character. The paint color is Calke Green by Farrow & Ball, chosen to feel classic yet rich next to the wallpaper.

After painting the trim, I realized the small mirror I’d saved from a clearance sale would be too tiny for the new scale. I hunted for a larger vintage-style mirror that could sit over the moulding and balance the wallpapered upper third of the wall. Once the new mirror arrived, I started papering.

This was my second time hanging wallpaper; this project required paste-on-the-wall adhesive rather than pre-pasted paper. With a small toolkit and a bit of patience the process went smoothly. The blue hydrangea pattern adds a classic, feminine touch that contrasts beautifully with the deep green paint below.

With the trim, paint and wallpaper in place, I focused on finishing details: a vintage-style mirror, brass hardware, and a few well-placed accessories. These final touches are what make the room feel intentional and complete.

The Finishing Details for the Powder Room

Here are the finishing touches that brought the design together.

I hung a small landscape print behind the toilet. It wasn’t the right fit for the kitchen design I initially bought it for, but it perfectly pulls together the greens and blues in this small room.

A seagrass lidded basket on the tank provides tidy storage for two oversized toilet paper rolls—yes, I measured first—while a decorative candle adds a finishing touch. The brass toilet paper holder and towel ring are sturdy and warm against the green paint. I swapped the plain white outlet and switch covers for satin brass plates to keep the hardware consistent.

On the floor, a scalloped green-and-jute rug adds softness and pattern; I’ll be adding a non-slip backing to keep it secure. Small choices like a brass trash can and coordinated switch plates help the design read as cohesive rather than scattered.

In the end, I’m so glad I chose bold color and pattern. There were moments of hesitation, but the result is a lively, elegant little room that feels purposeful and fun. Next up I’m planning a dining room refresh that will take a different direction—can’t wait to share that transformation as well.

Have you ever taken a risk with a small space like a powder room? It’s a great place to experiment.
