A 21” deep island has to be a mis Measure. The cooktop is maybe 21” deep. But that’s still not enough room to do a popup. And integrated is a big nope useless. None of your options address the terrible safety hazards here.

Option 4. Plan a kitchen remodel that gets the unsafe cooking zone off the island, fixes the too narrow aisles, fixes the ring around the rosy island obstacle, and just generally improves your ability to cook, and to enjoy the kitchen.

Not the best layout but single story will allow recessed cans and a hood. And you can cook from either side, Hooray. Bosch or Miele induction. Miele can communicate with a Miele hood.

WOW - I am constantly amazed by the rude comments on this site. It really is astounding to me. My question to you is do you enjoy cooking with gas, or are you willing/able/want to try something else. Personally, I would never switch to electric but induction has many benefits one of which is much easier cleanup. Answering that question will move you in the direction of what will work for you.

Overhead venting is always the best option. But that’s not a great or safe layout to be wasting funds preserving. Measure it all out, and look at what it’s going to take to create better function.

@live_wire_oak The cooktop is about 19'' deep and leaves 1.5'' per side for the island which has a 3'' rim. But you are right, it is hard to fit a pop-up and a cooktop on this island.

We could completely remodel the kitchen but just want to find a cost-effective way to live in this house for a few years.

@dan1888 @ProSource MemphisJust worried the hood on top of the island will disfigure this small kitchen.

The Frigidaire FPIC3077RF and Blomberg CTI30410 have the shallowest cutout depth of 30" induction cooktops on Appliances Connection.

There is one downdraft induction cooktop, the 33" Elica ENT432BL but it costs $4K.

You haven't drawn and posted a floorplan, but. . . it looks like that buffet segment and the wall might go to give you more room to reconfigure.

@dan1888@ProSource Memphis I add some measurement. Maybe it's not a good idea to move the cooktop to the cabinet 3.

That’s not a layout. A layout includes the entire room.

Well, not sure if other measurement would help

It'll help and the measurements widthwise and between the island and the counters will help. That dimension is measured between the counter edges not the cabinet faces.

You said initially that the island was 21" wide but your drawing shows 28". What is the width of the island, and the inside and outside dimensions of cabinet below the countertop that supports the cooktop?

It’s 39’’ between the counter edge and island edge.

@wdccruisek You are right. The inside of the cabinet below the island countertop is 21'', outside is 24'' + about 4'' rim = 28'' of the island

Wow, the Frigidaire induction cooktop linked earlier requires 19-5/8" cutout depth and the Blomberg requires 19-5/16" cutout depth. With only 21" available, would be a tight fit for the cooktop alone!

None of these clearances are good. Everything is non standard. You need a full renovation.

Full renovation is my last choice since I don't think I will live here for ten years. Just try to find a cost-effective way to get around

A lot of people simple would reject the safety hazard that your kitchen presents. Most people with kids would never buy it as is. Not without a 70-100K price drop to remodel it first. It’s seriously that unsafe.

We had an early 1980s downdraft electric cooktop, and once it caught fire, we decided it was time to replace it. :) There weren’t a lot of options that were the modern equivalent. We ended up installing an overhead vent hood and an induction cooktop. I loooove the induction cooktop because it’s SO easy to clean AND because it’s so responsive. I don’t think I’d ever prefer to cook with gas now.

@live_wire_oak Well, I am amateur. Can you be specific about the safety hazard?

@wdccruise That's one option. Thanks.
