Personally, I wanted a pleasantly decorated space to offer my guests when the need arose. But mine had the pedestal sink, no cabinets, an oval mirror and was stark white.
My solution was to faux the wall, I went dramatic even if it was a small space, I played with color. I used an eggplant basecoat and a green and gold glaze faux I did with a sponge.
I replaced the oval mirror with a nice wood framed mirror, replaced the faucet with a bronze oil rubbed version, along with the tissue dispenser and found this little pair of metal crates with hinged lids (Hobby Lobby) to seat silently at the base of the pedestal. See what I store there in the photo below.
The photo to the right shows a wooden magazine rack and a stepping stool for my grandchildren to pull to the sink when needed. They can reach the sink, soap, towel and light. Works good for us.
Hope these ideas help you with your half bath storage.
I will share my master bath potty area soon.
