The powder room is small. At only about 4′ wide and 8′ long, with a closet jutting into it, it’s practically miniscule. To even be able to fit into the room, a vanity was vetoed for a pedestal sink. It’s great for the flow of the room, but offers no storage, and barely a surface to sit a bottle of soap. If you want to set your phone down, or touch up your makeup, you end up having to use the toilet tank as a shelf for your things. Not ideal (or very sanitary for that matter). To gain a much needed horizontal surface in our Powder Room Makeover, we opted to install a small shelf. Take a look at what we made.
Custom Marble Shelf

- 1 4″ wide x 3′ marble shower sill
- 1 pkg corner brackets
- Spray primer
- Krylon gold spray paint
- 1 tube PL Premium construction adhesive
Tools:
- Wet tile saw
- Measuring Tape
- Drill
- Level
- Caulking gun
How To:
Measure available space (ours was 18″). Mark and cut marble to length with wet tile saw and diamond blade.

Install your corner brackets as shelf brackets screwing into studs, or using hollow wall anchors. We used black screws as we liked the contrast with the gold, and we have black accents in the room.




The bathroom is really coming along now. I will be back with another DIY project later on in the week.

That shelf is going to be very wobbly unless you have used a really thick corner bracket. A proper shelf bracket with a strut will add a tremendous amount of stability and improve the overall appearance.
The shelf isn’t wobbly at all and has held up to the test of time.
Wobbly? Why? If it’s secured to studs it shouldn’t be any problem at all.
You’re right Larry. It’s very solid.
Love it! What a great idea and love the painted brackets!! Nothing better than Marble and Gold!!! 🙂
I am so in love with black, marble & gold right now!
This looks great Kristen! We have the teeniest tiniest bathroom too so I know how much shelving can help in a space like this!
I have dropped my phone in the sink one too many times! Now…to figure out how to disguise extra rolls of TP in the tiny storageless bathroom. Any tips from a fellow small bathroom owner?
GORGEOUS, STUNNING! Love it!
Thanks so much Shannon! 🙂
The marble shelf looks awesome! I love the gold brackets, I just did something similar in my office with the gold brackets. Great idea.
I am in LOVE with the gold. I now want to gold everything!
That is BEAUTIFUL, Kristen! I love how you hacked that shelf into being. And the spray painted brackets are a lovely touch. Gold spray paint is my bestie. 😉
Can you believe it, but this is my first time using gold spray paint? Where has it been all my life! This Krylon one was from the swag bag at Blog Podium, and I’m so glad I gave it a shot!
