We have a lazy Susan corner cupboard where I jace a crockpot, instant pot, waffle maker, blender and griddle. Great and easy to pull out no big deal

@User I was planning to power-on the appliance only when the drawer is open.

NO. That is very very unsafe. You need to lift them out, and plug them in into an approved receptacle.

I have my small appliances stored in a tall cabinet with a "side door". It creates a sort of optical illusion as it can be accessed from the front with the same doors as the other cabinets but the appliances can be slid out as the counter runs continuously through.

I didn't want to have to lift heavy appliances or shlep them from the pantry or leave them on the counter to collect dust and create visual clutter.

As others have posted, it is unsafe to actually use any appliance inside a drawer or even a cabinet unless it was designed for that and/or has sufficient clearance - e.g. microwave in a cubby with sufficient clearance all around and used with door open.

There are very mixed reviews on the mixer stands. For starters, if you actually use the mixer ON the stand, you create potential more difficult to clean messes than when a mixture is on the counter.

The tall cabinet to the left has the small appliances and the door is on the left if you can picture it.

Here's a picture of the "left" cabinet showing the counter - door on the side is concealed.

I have my toaster, waffle maker , panini press in a deep drawer in a run of all drawer cabinets in an island. I dislike a lot of stuff on the counter so that was my choice I use the toaster once a day and the others less often , works for me. The toaster lays on its back to fit. I guess it depends on how you use the stuff and how much of it you have.BTW no to having anything operating inside a drawer I just lift mine out plug them in use them and put them back not much of a hassle.

For clients I usually do pull out pantries and there is always room for the appliances that are used infrequently like the deep fryer .You could even have something like this designed

Sliding backsplash to hide appliances. I saw this at a showroom in Chicago. The backsplash material is applied to panels that slide on tracks. Very clever.

Unfortunately, Mick DeGiuilio’s fabulous 250K kitchens aren’t very translatable to the needs of most of the country’s kitchen remodelers. The take away to the idea is the extra deep counters for appliance storage, not the very expensive concealment of the appliances and loss of other space for the logistics of doing so.

Just doing extra deep lower cabinets by adding blocking behind them is a doable an idea for the average 60K budget. That adds a couple of thousand to that from the extra deep counters alone. But it allows for the work space to not be impeded by the appliances there. You still get counter space in front of them, rather than it being taken away by having them there..

Ditto comments above - the appliances need ventilation while running to prevent them from overheating - and they generate a lot of heat. Trying to operate them down inside a deep drawer is going to create a lot of heat - possibly damaging the drawer, appliances, or worse.....
