I think a comfortable distance between the island and the counter is around 42". It seems that you have only 30" between your cook top and the counter. I might be a little too tight. The wall between the entrance and the kitchen could be 4' long instead of 6', you would then be able to move the island a foot which would give you more room between the cook top and the island. Could you switch the location of the toilet and vanity in your dad's bathroom so your enter facing a vanity instead of a toilet which is a lot nicer.

The wall is stunning and creative, but sadly, I have to agree with the consensus expressed on all your threads: this wood should have been bone dry, carefully checked over piece by piece for holes, insects, existing fungus etc., and probably treated and certainly well sealed before before being installed. At this point, I would cut my losses and take it down. Once the pieces are all down, it's possible that if you thoroughly scrub off all fungus with a bleach solution, then let them dry bone dry (preferably in a wood kiln or perhaps a DIY drying shed), then treat and coat, these pieces could be reinstalled. Even that depends on the conditions they'll see - if this wall is exposed to lots of steam or grease you'll be having new issues before long. Also, is the wall itself dry and solid? Any chance water is leaking or oozing from somewhere and adding to the issue? What species of wood is this? Some species are naturally more fungus resistant and appropriate for this than others. Long story short, I'd recommend finding a different way to cover the wall - with ceramic, galvanized metal, or with a really scrub-resistant paint.

there is many types of support to be used for counter top for long lasting work... as ... 1) brick wall which takes 2" , 4" or 6" thickness space which is not good for below space as we will waste space for storage under counter... this is used where heavy material is used on top of counter for cutting any food items... 2) marble support... which will take 35mm thk space double support... 3) furniture base if the kitchen working person is using the sink properly for washing purpose and the gaps between the sink and counter top has to be sealed properly for leakage free to avoid any damages for below storage, as i will not prefer this in other area... this can be used only in foreign countries...

I suggest you follow the step-by-step guide for creating storage cabinets under the bathroom sink. Take proper measurements - Measure the available available space in height, width and height. Cut Plywood to size - With a circular saw and framing square, cut all the required pieces out. You can use a sliding compound saw as an alternative. Attach the base and sides - Start assembling the sink cabinets by placing the bottom piece of plywood sheet on a flat surface. Attach the back and top boards - Place the plywood sheet for the top part of the cabinet and attach wood screws to connect it to both the sides. Turn the back faces of the cabinet upwards. Keep the back piece over the structure and fix it into place with wood screws. Attach shelves - Place the cabinet in an upright position to install the shelves. Slide a shelf into the structure so it is flush against the back. Attach door - Keep both hinges of the door on the same side of the plywood sheet. Drill them using wood screws into place. Now keep the door over the cabinet structure, extend the hinges to one of the side panels and fix them to make them secure. Fix a hasp closure on the other side of the door, placing it in the center of the hinges.
