Could clear up some basic plumbing definitions for me? I'm getting confused on the IRC's usages....


- A Lavatory?

I always thought a lavatory is a the entire bathroom fixture components (sink, toilet, tub, shower, etc). Seems IRC just refers to it as a toilet?


- A Water Closet?

I always thought a water closet was just a toilet and a sink. Seems IRC just refers to it as a toilet?


- A Laundry tray?

I've never heard this term before so I don't have a clue?


- A Laundry tub?

I think the IRC means the washer?

thanks, as I go away feeling very stupid....stupid is as stupid does...
