Hey cwiser, how's it goin'? Suggest you do a textured floor (less slippery) and a smoother (less grout, less cleaning) shower surround. Definitely do a textured shower pan, once again due to the slip factor.
Here's a nice classic (yet fun!) example of a non slip surface
This might be a nice tile for the shower surround

Have some fun with artwork and let her make her own personal statement!

Word of warning...she might use a Justin Beiber poster instead, lol!
Take care, and keep us posted!

if you think that is the best design you ever came across...take it, then buy. for myself, i like to design or create totally different from others. no duplicate !

Jamieson and magarita,
thanks for the great suggestions. I love the glam and creative ideas. But my almost-15yo, by contrast, is more traditional...plus she says Justin Bieber looks like a girl. (She's more into Adele, Amy Winehouse, Debussy, and "Moon River.")

I'll definitely take you up on those suggestions of the penny round mosaic tiles for the floor and big smooth marble tiles for the surround and shower ceiling.

What do you think of my throwing in a strip or two of colorful glass tiles somewhere in the surround, too? But how much is the right amount; when is enough Enough, as opposed to becoming Too Much? (For instance, the hot pink foil wallpaper in my big sister's bathroom when I was growing up sure became "dated" quickly. Ugh.)

Thanks!

For the shower pan and floor: Since we will use small tiles, should I order them with a smooth finish (looks prettier) or matte finish (less slippery)?
And what do you think of penny round tiles vs hexagonal tiles? (They will probably be all white with grey grout.)
Thanks again.

I'd go smooth for surrounds and matte for floors. Long as there is a color cohesion you should be fine. I like the idea of an accent strip in the surround. Might be able to use floor tile as an accent border, please see last photo. Hopefully you'll get more input from the rest of the Houzz community. Good luck, and keep us posted!

I guess my first question. would be how old is the girl and is she involved. An all white carrerra shower feels more like adults to me. Her personality needs to help her grow to being a young woman. and then returning from college. There are so many cool new products. Take a peek at Dream line shower, they come with pan and door and all glass.
If you choose to stay in the digestion you are going.

You can do the new trend that is timeless due to the styling of a framless custom no bottom pan, just walk into shower area. One I love is a simple tile 12 x 24 with a 1 foot mosaic pattern right down in front of the shower or centered along the back and then through tne shower floor and out to the bathroom floor. You could pick a multicolor mosaic and do still your white marble and the. mosaic with carrera, a color, and an. onyx. It is fun.

Or beige tiles very simple and pebble center line or make it wild and curve around down to the floor.Take a look at the photos here, this is where I found the pebble stones and I have used the idea, but in a straight line on the large wall as a focal point onside a wet room 1/2 shower door bathroom.
There is a lot of fun stuff, mesa steam showers come ready to go. music, lights, phones all white unit all glass door all very different than anything I would want, but it is coo,. And, she is young. There is steam for aromatherapy. It took me a long time to become used to this style as I tend to be simple and timeless. This was a new awakening. But they love it. And, that is what is important.

I just wanted to have you think of who is in here all white is cool, but showers when I asked my 28 year old he said oh cool stuff ya know phones, steam for shaving easier,
seat, music. And, I started looking around.

They also have some very pretty with interior closets for towels and shampoos, I think it is the New York Shower again with music and phone, teak floor, step out on to teak floor and you can paint room since shower is enclosed and maybe you need one wall for tiles. 6" x 20" subway in glass is what the teenagers are looking at in pale greys,'whites and beige, with this cool shower and teak floors.'zen type vanity a piece of furniture with a Buddha and a vessel onyx sink single faucet off wall very hip looking. room painted, so they can repaint later.
The .last look I did she was an artist and we went to photograph her photos onto water paper and she did a waterfall on the wall where you would enter the wall you looked at made the room huge this amazing 5 foot x 8 foot photograph. And it comes as wallpaper. We trimmed it out with a skinny brushed nickel frame, very thin just so the edges were safe from coming in and out of shower etc.

It is still pretty the room and simple. Behindthe vanity, which we hing off the wall. amd a low back water closet. For this we did a od looking porcelain floor very green, actually we were told she wanted green bathroom and tried but could not use inst hit heater .But she did get an energy save wc amd the same e on faucet. The shower we did not hook up jets like the others, but did a rain head with pebble floor very cool./

@COC,
I'd love to see your ideas, but no pictures were attached or linked.

always make sure the design created is not for short period. remember, keep as much money as you can for rainy days.

Your daughter sounds cool. I think something slightly old fashioned like the small hex tiles, maybe with black and white ones, will feel kind of cool and "New York apartment" to her, while still being perfectly classic forever. Man, my parents never designed a bathroom for me!
