You said the bath was 7' x 7' so those grey squares on your images each represents a 1' x 1' space. Right? If so, neither of the two designs you just posted is going to work. First, you aren't leaving enough room in front of the toilet or in front of the sink to actually use them. You HAVE to have room to stand in front of the sink and knee room in front of the toilet. (Men need standing room there also!) The 18' or so that you have just is NOT enough space. Building codes require a minimum of 21' of space. But, anything less than about 26' is going to feel decidedly cramped. Second, you cannot use a pocket door in the location you show it because that wall will have plumbing pipes for your vanity sink in it. A pocket door simply cannot go into a wall in the same spot where plumbing needs to be. I know you want a larger shower so I hate to say it but I really don't think a 3' wide x 5' long shower with a 4' wall around it will ever fit into the space you have available. If you went with a totally glass-walled shower and forgot about the half-height walls, the shower would take up less floor space. You might be able to manage a 30' wide shower. You might also consider a neo-angle shower that would fit into a corner of the room. Since both windows can't possibly be on the front of the house, maybe you could move or eliminate whichever one does not actually face front. Or, turn it into a glass block window and incorporate the window into your shower. A wall- mounted toilets with the tank (water cistern) built INTO the wall would also take up less floor space. If you put your toilet against an interior wall, that might be an option. And, while they don't provide under-sink storage, pedestal sinks make small bathrooms look and feel larger by freeing up floor space.

One suggestion...figure out your floor plan before you put down the new floor so that you can add at least one electrical outlet in the middle of the room where it will be hidden under the sofa. I think you will end up floating furniture to make best use of the space, so it would be terrific to have an outlet to use for lamps to avoid cords across a pathway.

Thanks for your suggestions! Yes the fireplace is working and unfortunately I think the TV is too big to put on the fireplace (it sticks out at the end, is that okay?). As for the dining table, there is no real space behind the bar stools. That is the entrance to our home and it's just a narrow hallway. The other thing I'm worried about with putting the TV where it is now is that the space behind the couch feels under-utilized... I was thinking of getting this TV stand, is this too high up do you think?: [https://www.houzz.com/products/tv-stand-milano-200-black-body-modern-90-tv-stand-led-gray-black-prvw-vr~104115228[(https://www.houzz.com/products/tv-stand-milano-200-black-body-modern-90-tv-stand-led-gray-black-prvw-vr~104115228)

You do have some really good options...My thoughts... If you don’t wish to remodel the master bath, I would not touch it. It is perfectly functional. Are you positive you would use a master sitting area? I know I wouldn’t sit in one. It’d become a dumping ground. I’d make it closet (or, in the first couple of plans, I’d consider expanding the kids bath or laundry into the addition area, with the balance being master closet. It does not sound like you would be happy with a laundry room that is only big enough for the machines.
