I would have shown the high pressure people the door. "SIGN NOW" = instant disqualification. Any deal you can give me today, you can give me next week. I'm polite, but firm, and have no interest in spending 2 hours of my life with an obnoxious pushy sales person. Notice who is saying "hire a window specialist" here - the window specialists! I've had a couple of replacement sliders installed in rentals by handymen. They did a perfectly acceptable job. One slider is now 30 years old, the other is 22. One has needed adjustment a couple of times. The other had to have a new roller installed a few years ago. No other problems. I could be wrong, but I don't think it's an especially complicated task.

Electric water heater, yes? I don't see how bypass doors are going to work with this situation. You will need three doors (32" doors) and a cased opening. This opening does not appear to be a typical 2x4 framed opening. You need the depth of a traditional casing in order to mount the track to the header. The track(s) will be a lot wider than bifold tracks because each door slides in its own track. IOW's, you will need three tracks mounted side by side to the header. I have bypass doors on three closets in my house. I so dislike them. I don't love bifold doors either but bypass doors are much, much worse.

Keep playing with drawing til something makes sense. I tried to sketch something out, let's see if I can attach it. Did you want to add a tub, or just a bigger shower? If windows can be added to the left wall, it would really add more possibilities! I made the bigger closet skinny so the window light still comes in. This loses the hall closets so it may need more work. I am not a big fan of the hall between the closets, it was my attempt to keep the window. Either of the closets where the master was could be removed to be a sitting area or a desk area. Obviously I am not a professional. I just like looking at and thinking about floor plans. I am sure others will jump in to improve my sketch by criticizing it lol. I left the toilet and one sink in place. I think the shower could use the same drain and it would not be too bad to extend the pipes to make it bigger, and add the second sink. The entry point is a bit crowded but I was having trouble adding a second sink if I made the bathroom door by the closets.

SO you each have a 7' x 13' closet? Outside a luxury sized bath? And more closets, un needed upstairs? You have a SPACE issue? Honey, I doubt it. You simply need to put OUT of season, upstairs. in season near the bath. Then call a California closet, or a Loews. ( yes.... they can do a nice job ) and together, with an ASSESSMENT of your cloting......sports, dress, folded, hanging, shoes, accessories, scarves, belts bags et ALLLLLLLL, You decide how you want to out fit the space. Thart's the shortest route, because clolthes are personal. If you tend a farm, your closet doesn't look like someone working o n Wall Street. The clothes required are different. If you can't find room for grooming and bath supplies in that bathroom? You need a major purge of who knows what : Maybe you need a make up table under that window. Only you know. Only you know your clothes. Maybe you're Sarah Jessica Parker, and maybe you aren't : ) You must "suggest....you" Lighting is dependent on ceiling height, and needs to be ether recessed or flush mount
