You should have minimum 5 ft but 6 ft is ideal. I've played pool where tables are 4 ft from the wall and it is too close. The standard pool cue length is 57" and the draw length is about 6" so 5 to 6 ft would be ideal.

Thanks for posting new views of your room. You are right, nothing can go in front of the paneling, and we won't block the built-in cubby. In that case let's work with the rest of the space. I found a picture on Houzz for your gallery wall. I think this will allow you to bring in color and texture and interest to your wall without taking up space like furniture would. Try to play with portraits and a couple of paintings in there too - mix it up. Otherwise I would not put anything at the top of that landing (I'd remove that console table). That picture wall should be enough visual interest to your space and it'll draw the eye to the furthest wall as you walk in your house. I would try a small piece with closed storage between the bottom steps and that door by the entry. It looks like the space is no wider than 26", so it'll be a challenge to find something that fits and is tall enough. I would not use the wooden piece you showed above because you want wider proportions and fairly narrow depth so you don't bump into it as you walk by. (something like this ) I would hang a mirror on top of primping. By the cubby you could add a single seat stool. I'm not particularly suggesting these colors for the stool and bombe chest but something along these shapes. At this point if you do that big picture wall and add these two pieces of furniture and a mirror, you might not need to hang anything on the wall above the cubby. Also, I noticed your chandelier is quite substantial for the space and hanging pretty low. Would raising it a little or replacing it by something a little smaller be an option?

We have a 900x900 shower and it's plenty big enough. Neither of your proposed layouts looks that great, to be perfectly honest, sorry! In the first layout, you could improve it quite a lot by swapping the toilet and vanity (centre the toilet under the window on the bottom right of the picture if possible), and having the shower door on the other wall (beside the door). Then, you could have a towel rail on the wall beside the door (i.e. behind the door when it's open), which would be accessible from the shower but hidden when the door was open. An 800x1200 shower might be a good size for your space. You'd have to choose a toilet that doesn't protrude too far, plus a narrow vanity. With that layout, you could have a long but narrow wall-hung vanity, with a big mirror covering the wall between the windows, which would make the room feel bigger and would give a good amount of storage.

A very simple layout keeping the floor space within the kitchen, the WIP takes up a lot of space with not much gain, The broom cupboard could be moved to the Laundry/entrance, narrow. If the wall has been bumped out to the eaves on the deck side giving an extra 300 depth to the kitchen you could make the island 2700 x 1200 and all drawers. The wall of narrow pantry will hold all pantry needs and more, no deep cupboards to dig into. cheers
