Hi Linda, if I understand you correctly, what you are looking for are "Undermount Range Hoods". If you do a search with this term, you should find links to numerous different manufacturers as well as retailers. Hope this helps. Regards Malcolm.

Here’s a suggestion: http://www.suncoastsheetmetal.com.au/cms/index.php/domestic/kitchens.html

Yes, but are you using the gap where rangehood was to centre, or the centre of the cook top. If you have cabinetry along the wall then you can hide the fact that the extractor fan/rangehood is not centre of the cook top. Or that is how it appears in your photos.

My family is looking to buy a new range hood. Ours right now is just too weak, it doesn't really suck air out. What do you guys/gals recommend? We've looked around and saw this one: Broan 413004 ADA Capable Non-Ducted Under-Cabinet Range Hood Do you think it's good? Any opinions? Thanks!
