This isn't about teen baths, but about shower curtains in general. It is impressive how a shower curtain can completely change the feel of a bathroom. I dislike our vintage gray bathroom, but renovating it isn't in our budget right now. I bought a blue, navy, yellow & chartreuse striped shower curtain at Target and the entire room looks completely different. The gray recedes, and it's a cheerful place now. Will look even better when I paint the walls, most likely to match the yellow. Upstairs we have a vintage yellow bath that I do like, but there's just too much yellow in such a small room, with the yellow wall tiles, floor tiles, and fixtures. Recently on an AT home tour a Garnet Hill curtain with a pattern of zinnias in yellow, orange, rust & blue was featured in a vintage salmon bath. The curtain looks amazing in my bathroom, and I'm going to paint the walls to match the blue.
