organize tp, towels, toiletries in pretty baskets on the shelves you have...I'm thinking the fabric baskets, not wicker.

white or ivory towels are classic.

For curtain and rug...what color do you like?

Great ideas!! My favorite colors are "cool colors"... teals, blues, greens, magenta, purple. Based on Analie's suggestion, maybe a lighter version of those colors?

If you were drawn to the shower curtain, keep it. Just try pulling it to one side instead of keeping it closed. It's fun and beautiful. Look up photos on houzz of small bathrooms...I posted 2 in my ideabook under bathroom if you want to see.

Keep your blue towels and organize your things into baskets...you can get those in teal or purple solids or patterned. This will throw the pops of color around the room and the space will look tidier.

Toss one of your towels on the floor to see if that's the color of rug you want.

P.s. Close your toilet lid when taking photos for houzz...houzzers hate seeing them open! Lol

We can't possibly know your preferences in colors,patterns,etc. go to Bed Bath and Beyond and wander around. Search houzz for photos of what hits you.

Storage....baskets always work:)

Have fun!

Sorry just saw your color preferences...still, best to go actually look at shower curtains,towels, etc.

Add curtains to the shower and take them up higher to give the look of custom shower curtain,so regal
