Household appliances - no site I know of allows you to search them based on the width, height and depth but for people who are replacing them, then that is often the first consideration - yes there are 'standard' sizes but how many houses are built to standard :) Another thing of course is when buying an oven or fridge, important consideration is capacity. I would love to be able to search for say 'show me all fridges which have a max width of 90cm and order them by capacity'. Add In price comparison and links to buy
