Products for singles

I visited my friend's new condo apartment on the weekend. He is single too.
The shower curtain in the bathroom is pretty nice. Two layers, sheer fabric on the outside. I was looking for some sheer shower curtain myself. Living alone, see-through curtain is not a problem for me. Lighting is more important. However, the ones with nice patterns are so thick that it would block all the lights from outside and I have to shower in the dark.

It occurred to me that most of the products on the market are designed for family. In addition to see through shower curtains, I also want
easy to prepare food in small portions;
nice china set for one or two persons, not 4 or 6;
smaller car with two seats (almost bought a smart car, if it looks less like a shoe)
hotels for single travelers (like hostel but with better rooms, and a place to mingle)

Some one should take the singles' market seriously and design some cool stuff for singles. Hello, we do have buying power. Maybe that some one should be me.
