Ah yes, the perennial spousal debate over counter and cupboard space for coffee equipment and stuff. Even with the Decent (turned sideways against the wall) and one grinder (the Niche Z) also turned sideways, my wife still complains about the space it takes up on the counter. Both have smaller footprints than my prior Lelit E and Eureka Mignon. Meanwhile her Kurig has a sizable footprint on the right side of the counter.
Anyway you are fortunates that your wife has agreed to actually giving up floor space for your stand (and drawers below).
Do suggest that you spend some time at Ikea and also stores that focus on furnishing apartments and condominiums, for ideas.
