Bought myself a 300$ 'portable' dishwasher from my "local big box home improvement store". Fits about a day and a half of dishes, up another half day depending. Runs in 1.5h and right off my tap so no dedicated installation.

I invested another 100 in a flat topped utility/tool cart and set it up on that so i can wheel it out of my kitchen when i am not using it.

My wife approved.
