Get someone local to have a look.

I'm in the Midwest and while it seems common to me, I don't know that its a fact regionally...but it seems that men in particular like having their "man shower" down in their "man cave" that they don't have to get fussed over about. Or in my sisters case her "woman shower" since her husband is a total controlling neat freak and insists on squeeging after every shower. So she uses the cheap fiberglass stall in the unfinished part of the basement. I just looked at a house for sale - by the kitchen door that comes in from outside the wife insisted the husband take the half bath and put in a shower - he wasn't allowed any further into the house till he'd used it. And as a gardener and pet owner - I'm with sniffdog.

Storage, storage, and more storage. Think about how you want to use the space, and plan plenty of closets to accommodate all the things required. Otherwise, you will have a job on your hands to keep it from getting junky. So here is more than you wanted to know about what we did: When we did our basement, which also included a long one-car garage along half of one side, we put in a u-shaped light shop space (no power tools except drills and the like) at the end with a deep sink in the center of the U, one side dedicated to plant care and flower arranging, peg board (painted white) lining the walls up to 6'8", and a deep shelf on ordinary white hardware store brackets above that. I recycled two L-shaped wooden countertops that were cast-offs from another project, stained them, and finished them with spar varnish. I designed the supporting structure (painted dark gray) to accommodate three mobile storage basket units that I already had. I painted the wall over the sink (no pegboard there) with chalkboard paint, which was great for jotting down measurements and things to go on the shopping list. We used plain old rectangular florescent tube fixtures in the ceiling, which gave exactly the kind of clean light we needed, and a couple of boxes of peel and stick vinyl tiles on the concrete floor. The short wall of the house which had the garage door and the entry door from the driveway was our foul-weather entrance, and had a fireplace in it, so I allocated half that space to a warm sitting area, and put a trestle table to serve as a desk behind the small sofa that faced the fireplace. I dealt with the high little windows along the long wall (with a lovely view of the bottoms of the boxwoods along the front of the house) like this: Behind that area, I created a hallway to the back space by building a cedar closet on one side, which ran under the staircase, and a long deep closet with three doors in the wall and deep shelves lining the whole thing on the other. Where the cedar closet ended, under the low part of the stairs, I built in a niche for a long 2-drawer lateral file cabinet. We had the stairs rebuilt to create a 3 x 3 landing at the 3rd stair up, so we could turn the bottom stairs to face into that hall, and create an easier and more attractive entry to upstairs. Beyond that hallway was enough space for a pantry closet and a wine closet along the short wall, and a chest of drawers perpendicular to that. Beyond the stairway was the door to a new laundry room and a walled-off area for the HVAC and hot water tank (with louvered doors), and between the laundry room and the back wall of the garage workspace, we put in a big bathroom with changing space for anyone using the pool, or coming in from the garden all covered with muck. We did the bathroom very economically - the things we spent any money on were a Venetian marble shower stall and long countertop with an integral sink. Instead of a vanity, we mirrored the wall and attached a simple framework with a stained birch plywood fascia along the wall to support the countertop, built a 10" high plinth along the floor under it, and put big baskets of towels and washing and sun supplies on it. Then we ran a 2x10 along the wall opposite the shower with many hooks for damp towels and bathing suits, and added a simple garden bench. I loved it. It made my too-big house completely manageable.

So I did this as if it was my space. assumptions are all smaller appliances. Such as 18" bosch dishwasher, GE top mount stainless 28" wide refrigerator, 24" wide stainless GE electric range, 24" Recirculating stainless range hood by summit. Freestanding fridge (built in takes away valuable inches). Solid countertop surface. Single bowl undermount sink for the corner such as Kraus KBU11 (20*17). I say choose which side ismore comfortable for you during prep to determine trash. I personally would want the trash next to the dishwasher. If you want regular sized appliances (30 stove, 36 fridge, 24 dishwasher) then you will end up with no trash cabinet, a 6” space like upright pan or wine cubbies, and a bank of 12” drawers in your base. There are many kitchen carts you can choose from and closed or open storage. In this plan I would expect to put pots and pans at that cart. I dislike open due to dust, grease, and most importantly my cats (or if we had young kids). Not interested in having them in kitchen things.
