Sure, it is possible. Nothing complicated. Just basic math. You need the dimensions of the cooktop, the required installation clearances, the thickness of your countertop...
This would be a very difficult expansion job. The lower cabinets have to be modified to accept the wider stove and ducting, and the countertop needs to be opened by 6″ Without cracking it across a very narrow bit of countertop. Then the support wood needs to be adjusted or re-supported to fit the new opening.
What are common cooktop sizes? Standard cooktop sizes often correspond to common cabinet widths: 30" and 36". But, cooktops can range from a slim 15" - 24", to larger 45" and 48" wide models depending on the number and size of burners, amount of trim and more.
INSTALLATION NOTES
Wolf recommends using a 33" (838) wide cabinet with the 30" (762) framed electric cooktop. A Wolf downdraft system, Cooktop or Pro ventilation hood is recommended.
For an upscale remodeling project, most designers recommend at least a 36-inch model. They're large enough to fit at least five pots and pans with room to spare, and offer enough oven space for dinner parties. We looked into some of the top-rated dual-fuel ranges on the market.
Generally, most 30-inch cooktops have four or five burners, and most 36-inch cooktops have five or six. For cooktops, both electric and gas are capable of delivering decent performance. But with gas, you may find it easier to judge heat by appearance of the gas flame.
Guidelines recommend a minimum of 12” landing area on one side of a cooking surface, and 15” on the other side. In a peninsula or island situation, it is also recommended to have 9” of countertop behind the cooking surface if the countertop height is the same height as the surface cooking appliance.
Dimensions: 36" W x 3-5/8" H x 21" D. Cutout Dimensions: 35-3/16" W x 19-13/16" D.
Take a measurement near the back of the cabinets and the front to make sure they match. If not, go with the smaller dimension. A standard cutout width is usually 30 inches wide to accommodate a 30-inch range that is actually 29-7/8 inches wide.
For example, a 30-inch stove may actually measure at 29⅞ inches wide, but it will require a 30-inch cutout for installation. It's important to check the exact specifications of each stove to make sure it will fit your available space.
Two deep drawers beneath your cooktop will give you plenty of storage for your pots, pans, and lids. Rather than two deep drawers, you might choose cabinet doors under your cooktop. You could add pull-out shelves in these base cabinets. This is another great way to easily access your cookware.
Typically, cooktop sizes range from 15 to 36 inches wide to accommodate small-space apartments and large kitchens alike. Looking for more space to create? Commercial-sized cooktops can range from 30 to 48 inches wide, and sometimes larger.
The 30-inch range is the most common size out there. This is what you will typically find in a regular household kitchen. It's big enough to serve its purpose for daily use and it doesn't take up any extra space.
Most standard stoves are 30 inches wide, around 25–27 inches deep (excluding handles and knobs) and 36 inches tall (excluding control panels). These standard stove sizes are designed to fit standard cabinet cutouts that are 34-1/4 inches wide, 24 inches deep and 36 inches tall.
It's recommended to have a minimum of 8" counter space on either side of the cooktop for ease of use and food preparation. If you're installing an island cooktop, you'll need at least 30” of counter space around the cooking surface to provide adequate room to work with pots, pans and ingredients.
Take into account whether or not your kitchen has enough space for a wall oven. Standard kitchen ranges are typically around 30" wide, but a wall oven of the same size needs a 33" wide cabinet. It's possible to get smaller wall ovens, but this could also impact your ability to cook larger dishes.
As far as the range, 30 1/4” is standard for a 30” stove. Any less makes it hard for the installer and the customer if they ever want to slide it out. I feel you should never go less than 30 1/8”. As far as the refrigerator goes, I think it would be better to allow a little more if you can.
This gap will enable you to install virtually any standard oven housing unit. It will also help shield the surrounding cabinetry from the oven's heat. A 30-inch-wide range is typical for a wall oven. As a result, you will often require a 33-inch cabinet to accommodate it effectively.
Allow 7" minimum clearance from edge of cooktop to nearest combustible wall on either side of unit. Installation of drawers beneath cooktop requires minimum 8" clearance beneath countertop surface and assured clearance for gas and electrical connections.
What size range hood do I need for a 36″ range? A 42″ range hood is the best option for a 36″ range.
Distance – A
600 mm minimum unless manufacturer's installation instructions (cooking appliance / range hood) require a greater distance.
600mm of vertical clearance to a combustible surface, and 200mm of horizontal distance to a vertical surface. If these measurements can't be met, the surface in question must be protected with a fire resistant material in accordance with AG/601. 600mm to a rangehood.
A good rule of thumb is to allow between 42 and 48 inches between your range and a cabinet or island. If there is often more than one cook in your kitchen, opt for the higher number.
