My current sink is a standard 32" double-basin. It's what I've always had, though I am certain that I want to go with a single basin for my new house . . . the other day I was staring at it, imagining it as one BIG bowl, and I thought to myself, "People are crazy." Who wants to fill this whole thing? Remember, too, that everything is a trade-off. For every couple inches of sink you add, you lose a few inches of cabinet space. What do you need? Personally, I think 24-28" is a good size. If I had a monster-sized sink, I think I'd rather constantly use a small dish basin for washing things . . . and that'd be fine, though rather like the double basin sink I have now. One last thought: I totally agree that washing refrigerator shelves is a pain; however, we only do it once or twice a year. I can't see buying a sink JUST for that purpose. Yeah, I splash water on the floor when I do it, but I can live with it. If it's a big deal for you personally that your refrigerator shelves are always spotless, I suggest that you cover them with the peel-and-stick type of plastic wrap. Then, when they get dirty, you can just replace the wrap rather than washing the whole thing.

You can hang balloons or paper plates or anything like that from the ceiling to get a sense for the scale. There are a few more you can look at too: Kichler Sayre takes up less visual space because it's flatter, but it may be too indusrial for you. Also, you have to get the biggest size to get a 100W bulb. You may be able to use the middle size with a 60W halogen (it can take up to 75W) and get the same amount of light as a 100W incandescent. Quoizel Emery comes in a bronze, but it's much prettier in this silver. It comes in a small size with a 100W bulb, but that size doesn't have a diffuser. Savoy House 7-602-1 is the least expensive one I've found, and it's kind of cute: If I think of any more I'll let you know. I'll keep an eye out for something with pretty glass, too. Can you tell I'm obsessing over my lighting now?

I don't need much room at all for my makeup. Like enduring, I keep all my daily cosmetics in a plastic bin - take it out, use what I need, put it back. However, I also don't need a 24" sink. I'd personally reduce the size of the sink and increase the size of the counter. And a 40" sink - is he bathing in it LOL?

I doubt they would stay for extended time in the US when they have severe health problems. It is not financially possible for a non US citizen to stay here and use the medical services by paying out of pocket. So for what the OP is asking - a small bath for non-stair climbing guests is definitely doable. I am sure your parents would not be complaining for the few months they are here when they have the chance to spend time with you and your family. You are being very shortsighted. Just because someone has some mobility issues doesn't mean they can't travel. My aunt used a walker for the last 18 months of her life, yet still managed to go anywhere she wanted by walking and using public transportation in NYC. A walker still requires more space to maneuver. Are you saying that the OP's parents won't be able to visit if they have a walker or a motorized scooter?
