On Height Adjustable Vanities

I have been searching for products that are height adjustable in the bathroom and have come across products from:

Enware – http://www.enware.com.au/estore/category.aspx?id=2930&FolderID=26
Linido – http://www.linido.com/index.php?page=producten&hoofdnav=6

I am wondering if anyone has found any other companies that provide height adjustable bathroom features – vanities etc?
