Laundry: I use "laundry bags", they cost about the same as hampers. I keep them in my bathroom and office (work from home) because I have to start work much earlier than my family so get dressed there in the morning. They are portable, don't look that messy (just a black bag) and easy to tote around when full.

Edit - forgot to mention (of course) that a big bonus for having one of these in my office which is near our kitchen and living area is I throw all the socks people take off and hoodies, dish cloths, etc into it which keeps the dog from stealing them and keeps the main area tidier.
