The big issue is having the noncombustible assembly behind the range. Quartz will scorch and burn, as well as some stone sealers that people use on cement of other porous tile.

It appears the Bosch induction range installation manual says that the minimum distance from the wall must be 25". It does not "suggest" that as you said - it requires it. Your range sitting proud of the adjacent cabinets by 3/4" more than that minimum required distance is nothing. Many pro-style ranges, especially beefy all gas ones like the Wolf, sit proud of the the adjacent counters by 3-4". That is so that the oven door sits proud of the adjacent cabinets so when the oven door is open, the heat does not burn the adjacent cabinets.

When the oven does not sit proud enough from the adjacent cabinets, this pic shows what can happen, so your concern over 3/4" being "noticeable" is not worthwhile.

It’s an induction, does this make it okay? No open flame. The backsplash is soapstone. Thanks again.

Most of the larger ranges stick out varying amounts, so that shouldn't be a problem.

The stone backsplash is not an issue.

Here is a photo of the induction range from the Bosch website. Bosch shows it sitting proud of the adjacent cabinets.

You’re good on the backsplash. Soapstone can withstand any kind of heat. And, with induction, certainly.

M Miller:
I think you’re misunderstanding me. I don’t care if the range sticks out. I was concerned that in the Bosch drawing is says adjacent cabinets minimum 25” depth or maybe I misread it as you said the 25” is minimum distance from the wall?
Either way, the drawing shows the range beside 25” depth cabinets, it vents out the top back… doesn’t say much else about having it sit further out.

M Miller:
This is what I was referring to. Am I misreading it?

While soapstone should be unaffected by anything the range can do, it is thermally conductive, so very high temperatures on its surface could lead to deterioration of combustible materials behind it. This would be an issue with a gas cooktop where standoff distances are specified with island trim, but seems unlikely with induction or from the hot air rising from the oven exterior venting.

Soapstone is literally impervious to heat, that's a non factor in splash decision. A pot from the stove set directly atop it ? Same thing, no worry . So too is the minimal jut proud of your cabinet: )

There's nothing you could cook in that kitchen that would set ANYTHING behind that rock afire. It is a rock. Literally.

"Soapstone, also known as steatite, is a metamorphic rock composed primarily of talc, with varying amounts of chlorite, micas, amphiboles, and other minerals ..."

Jan: Soapstone is not impervious to heat, but it is unaffected by heat until about 1000C where it turns into a hard ceramic used for electrical insulators. But the game is not the soapstone hardiness, but what lies behind it.

May I direct your attention to IMC subsection 308. Soapstone is not listed as a reduction method for protecting in-wall combustibles from heat deterioration.

"When wood is heated at elevated temperatures, it will show a permanent loss of strength resulting from chemical changes in its components. The thermal decomposition can start at temperatures below 100°C if wood is heated for an extended period of time." from the abstract of Thermal Deterioration of Wood, Fred Shafizadeh and Peter Chin, Wood Technology: Chemical Aspects, Chapter 5pp 57-81, ACS Symposium Series Vol. 43.

"As wood reaches elevated temperatures, the different chemical components undergo thermal degradation that affect the performance of wood. The extent of these changes depends on the temperature level and length of time under exposure conditions. Permanent reductions in strength and modulus of elasticity can occur at temperatures >65 °C, with the amount depending on the temperature, pH of wood, moisture content, heating medium, exposure period, chemical treatment, and species (Winandy and Rowell, 2013)" from the abstract of Wood Products Thermal Degradation and Fire, Mark Dietenberger, Laura Hasburgh, 2016, Forest Products Laboratory, https://doi.org/10.1016/b978-0-12-803581-8.03338-5.

This is not an induction cooktop issue, unless flambes are routine. But the island trim issue for gas cooktops is still an issue for code enforcement and safety, and I fear misinterpretation of your remark could leak into the more general cooktop case.

Lots of things are "possible". It is possible you could get broadsided in your own auto today, but off you go in spite of that possibility.

The average kitchen sees very little flambe....may see a ton of stir fry! We could wring hands all day about the solid surfaces or tile that cling to drywall behind a range. Whether that is an ordinary 30 inch slide in from Home Depot, or a luxury 48 inch monster, from Wolfe.

What happens? Essentially nothing. To any of the walls or cabinets, or tiles, or drywall or wallpaper surrounding them. The granite lives, even the quartz and marble and dolomite live with no melting down of the wall behind or cabinet nearby. EVEN those with something clear down to the adjacent counters.

There was a reason your old biology lab had a soapstone counter top. Microbial as in ANTI!! and that little Bunsen burner. I think she can relax.

We had similar constraints when adding a soapstone backsplash behind our gas range in our new build. Our GC removed the drywall from that section first then the fabricator mounted the soapstone directly to the wall studs.
