Maybe I can help. Our house was built in 1962 and, interestingly enough, we are just finishing a master bath with exactly the same dimensions as yours and pretty much the same layout. All that remains to be done is for the shower door to be hung; that's another story. As I said, our bath is 7 feet long and a smidge under 7 1/2 feet wide. We also have a window over the toilet, but our wall with the vanity is on an interior wall, so no window there. The layout for our bathroom is exactly what you have in your plans, with a couple of minor differences. Our shower is 48" long, but only about 32" wide. We put a half wall between the shower and the toilet with a clear shower enclosure on the front of the shower and above the half wall. That provides a little privacy for the toilet area and prevents it being seen from the bedroom while maintaining the open feeling of the clear shower enclosure. We put crown molding all around the bathroom since the shower enclosure doesn't go all the way to the ceiling and so we weren't concerned about the humidity and the wood. The shower enclosure is tiled to the bottom of the crown molding and there is a bullnose decorative tile with a black pencil accent tile right below it that runs through the shower and extends all the way around the bathroom at wainscot height. We used a white subway tile for the shower enclosure and below the bullnose tile around the remainder of the bathroom. The subway tile and decorative tile form the backsplash above the vanity. Our plumbing for the shower is also in the wall between the bathroom and the bedroom. We used a black and white porcelain basketweave tile for the floor, both in the shower and in the remainder of the bathroom. The black accent tile on the walls and the black "dot" in the floor relate well to each other. Since we don't have the issue of the window over the vanity, we put two sinks in ours and there is plenty of room for them. The countertop doesn't feel crowded at all. As far as the grout goes, we used white epoxy grout (I don't know the brand) on the walls, and a dark gray on the floor. I've been using the bathroom, other than the shower, for a couple of months now, and the floor is pristine. While white grout was also recommended for the floor, I was too skeptical for that. The dark gray actually adds some definition to the tile pattern and there is no worry about the grout discoloring. Our vanity is 21" deep which is one reason our shower is narrower. We used standard cabinetry and the cost was relatively reasonable. It was amazing how much this small room cost! Our bathroom door does swing into the bathroom and into the shower. The only place we could find for towel bars was on the back of the door so we had to be really careful that the height of the towel bars kept them from colliding with the handle to the shower door. We also put a stop on the door so that it doesn't swing into the shower. It isn't ideal but the only way it would work for us. I don't yet have pictures; I'll try to post some in the next couple of days. Before the renovation, we had a bathtub and a small linen closet on the wall which now contains the vanity and the vanity was where the shower now is. We, thankfully, didn't need to move the toilet. I hope this has been helpful. While the bathroom is cozy, my husband and I don't generally use it at the same time. But if we did, there really is room for both of us with the double vanity. Good luck!

Just cross posting here to see if anyone has any advice for this upcoming bathroom remodel! We bought our house just over a year ago and the time has come to remodel the master bath. From crumbling tile to a rotting wood strip filling in a huge gap between shower enclosure and wall, this room was the most obvious negative about the house when we bought it and still is. It is also TINY - 6 feet by 6 feet, but with a (currently unused) chimney stack bumping out into one corner. Here's the current layout: As you can see, it's tight in there! I know there's no real hope of making this bathroom large enough for two people, but I'd love to have a little more space for myself. (Since it's just the two of us most of the time, my husband has basically made the hall bath his own - this actually works better for us than sharing anyway.) However, I don't think there's any other possible layout for the fixtures unless we either remove the chimney stack (which is on an exterior wall) or steal space from the closet that is next to the bath on the left. Here's the floorplan for the second floor, with the bath in question on the right side of the house: The closets to the left of the bathroom are a nice size, but I wouldn't mind losing a bit of that space and/or reconfiguring it to get a better bathroom layout. The bedroom behind the toilet is the guest bedroom and the closet in there is mostly used for linens - it is more than large enough for our needs. The walk-in closet in the master is nice to have but I'm not sure the space is used as efficiently as it could be. Anyway, I would appreciate any thoughts you may have on how to improve this space! I haven't gotten an estimate for removal of the chimney stack yet, but we did have someone come out to look at it last fall to see if it could be made functional, since the fireplace attached to it is in the living room. He said it was possible, but given the age and condition of the stack and the size of the fireplace itself, it would probably be quite costly, and recommended that we simply seal off the chimney instead. Personally, I would prefer to spend the money having the stack removed (if it's not a structural element) to reclaim the space. Thanks in advance for your thoughts!

@emilymch - It's great you're planning and thinking this through. Either of the 3 plans seem to work. It's all about the toilet and some tradeoffs. I really think the 72 inch vanity is key. A 60 inch vanity leaves little room between people AND the sinks are usually ridiculously small. I'd sacrifice in other areas to get more vanity space. Adding walls will reduce the size of things which may not be optimal. For instance, take your layout where the toilet is on the upper left. You've got 147 inches on the long wall. Code requires a toilet to be 15 inches from the center of any obstruction so the minimum width of your WC is 30 inches. Depending on where your floor joists are the room may have to be larger. So at the minimum you add 4.5 inches for the wall to enclose the space (more if adding a pocket door). Then add 72 inches for your vanity and another 4.5 for your shower pony wall and you're at 111 inches. You've only got 36 inches left for your shower. It would still be quite spacious the other way. Would that bother you? If you could steal 6 inches from your closet, that would help, but that's getting into another expense and you may not have to space or want to do that. The same goes if you keep the toilet where it is and turn it. Obviously this doesn't happen with a 60 inch vanity, but that's not a choice I would make. A 66 inch vanity would be better but they are few and far between. Ordering online without seeing the sink size is not wise. My sister just did that (against my advice) and is very disappointed in the size of her sink. She says it's "mini". If you leave the toilet where it is, then things work out better. 42 inch shower, 4.5 wall, 72 inch vanity=118.5 which leaves you 28.5 inches left for storage at the end of the run, which should be good. I wouldn't put up a pony wall or anything. Your toilet would be open. Does that bother you? It wouldn't bother me, but we are all different. It' always trade offs and $$$.

Thank you for your feedback! I've checked, remeasured and updated the first diagram above to provide all the wall dimensions including between the door and window. The odd thing is the door is almost centered in the wall. I do not want a tub, only a shower for 1 person. For the shower, I want a shower pan (i.e. cast iron or acrylic), not have the shower floor custom made with tile. The shower walls will be tile with a glass shower door. I also have a cabinet maker who will build a custom vanity , so there's no worry about the length of the vanity. I would like two sinks in the vanity. I don't want the window in the shower. I'll put together some additional diagrams regarding possible fixture placement, although if there's an obvious placement that clicks, I'd appreciate those suggestions.
