I have a rolling metal work table. Well, it rolls now. It didn't when I picked it up. I have modified it a lot. First up was stripping off all the old lead paint and who knows what else. Then because the steel top still had a lot of stains that would not come off, I covered it with zinc (natural antimicrobial and neither of us are allergic) but could have done copper for the same reason. I don't know what can leave a black greasy stain on steel that bleach, ammonia, or orange oil won't take off and I don't care to have any of that in my food, We put locking casters on it so I can roll it around to work or clean under it. Its just the right height for working with appliances like my stand mixer and food processor when I am really in full swing on processing stuff, be it food, hair gel or
soap. It adds a ton of storage for commonly used items and I recently put a lid rack on one side to hold all the lids for the pans. It wipes clean and if all else fails I can roll it out to the back porch and hose it off. Its definitely taller than the kitchen counters. My last house had a kitchen built for someone very short. The counters were a good height for me to make pastry but otherwise required a lot of stooping over which I hate.
Another thing to consider in your kitchen is your flooring. Yes, it is probably not very
sustainable but the antifatigue mats are real boon if you have any feet, knee, hip, or lower back issues. Even on a pier and beam foundation, having that extra cushion means that working in that area takes a lot less out of me at the end of the day, If you check the
local restaurants or going out of business sales you can get the industrial ones for a song and I have not had to replace them yet. The dogs seem to like lounging on them and get rather put out when I give them the
boot so I can start my project.
