Only the island or the wall cabinets as well? Appliances may not fit well. You will need to raise the uppers as well. Do you have room for this?

First, I suggest you engage the services of a designer who has worked with tall people.

Here's a long discussion on this topic right here on Houzz: https://www.houzz.com/discussions/2603118/raised-counter-heights-for-tall-cooks

No, it would be for everything. We have 12 foot ceilings so the height would not be a problem. I would only have to lift the gas stove and dishwasher. The other appliances will either be in the island or a cabinet built for fridge.
GC mentioned putting wood under the oven to raise it. It’s a 36 inch gas stove/electric oven.

Thanks Bill, for pointing me to the discussion!!

I would make the perimeter counters taller, but leave the island standard height. My perimeters are standard height, but the island is ap 34" tall, which is a good height for me for rolling dough, kneading bread, etc.

36" should be a good work-table height for you, but there is a graphic which helps measure the exact height one would need. Also, if there are a couple of inches difference in height in family members, each can choose the lower or higher work surface, and that would eliminate the bar stool dilemma.

How tall is tall? Is your height in your torso or in your legs? How long are your arms? We have 39” countertops, which seems to work out just fine for the long legged ones. But for me? Not so much! I may be 5’10, but my inseam is only 32” and my arms are pretty long, so, from an ergonomics standpoint, my counters are too high for doing most kitchen tasks optimally. If this isn’t a problem for you, though, go for it!

I have raised counters and it is heavenly! I don't know what issues there would be to deal with. I don't have a range, cooktop and wall ovens instead. The dishwasher did not seem to pose any particular challenge. Of course you have to consider the uppers. For anyone considering this, as a not especially tall woman at 5'9, I highly recommend- it makes working in the kitchen so much less stressful. If I were not able to redo all my counters, I would have a raised island or work cart at a minimum.

We raised all our counters (kitchen and bathrooms) by 3" for our tall family. It's so much easier on my back when I'm making a big meal (eg holidays) and my son (6'6") and daughter (6'1") especially love their bathrooms. We did custom cabinets so we didn't just raise the toe kick or use a crown under the counter; we have larger cabinets so we have a bit more storage. The DW sits on a small platform, which is hidden by the toe kick.

I've never been one to think too much about resale, because you can't second guess what someone else will want. However, now that my house is on the market I'm getting some pushback that some people don't like the high counters (esp. in the kids' bathrooms.) I've had 12 good years with my high counters so I'd do it again but wanted to tell you what I'm hearing. (To be honest I'm surprised because my grandma had standard counters and never complained, and she was 4'11"! I'm 5'11" and only raised mine by 3" to 39"; most people are taller than my grandma was so I feel like the counters should be fine for almost anyone.)

I'm definitely one who would walk away from your house if it were on the market. Unless it were priced so to make a complete re-do of the kitchen back to normal counter/cabinet heights, it would be a money sink for me. But as others say, do what you want for yourself. Just don't expect everyone to love it when it's time to sell.

Thanks everyone for the feedback. We plan to stay here at least 10 years, so I guess it would be best for us to raise it. We are all between 5’10 and 6’2.
I didn’t think about the kids bathroom counters, but best to raise those as well, custom build.
Nice to see people take their time out to help others. I am so appreciative.

Another thing to consider for taller people is the seating overhang. NKBA recommends a minimum of 15" for comfortable seating at counter height, but your family might need a couple of extra inches.

I don't think it would impact resale because nobody will notice until it's too late! It'll LOOK standard.

I had raised cabinets (about 3" above norm) in a house I just sold in FL. Not one person noticed or commented on them being raised. When my mom, who is 5" came to visit and used the kitchen had no idea they were raised.

Don't worry about resale...no one will notice it...and do it! I'm in a different house that doesn't have raised and I miss it.

We raised all our bathroom counters and just the island in my remodel. Love it and honestly nobody would ever be able to tell a difference. What we did do was put a really thick counter just on the island and regular height on the perimeter and it did the trick.
