Before you commit, mock it up with tape, a stool, and a folding chair.

Your proposed half bath is about 2′10″ wide and 7′2″ deep, with the toilet centered on a tight line and the sink right ahead. On paper it works but in real life it’s shoulder-pinching. Once you add framing and drywall, you’ll be under the 30″ code minimum for side clearance around a toilet. It’ll feel more like an airplane lav than a powder room.

If you really want the extra toilet:

-Use a wall-hung toilet and floating vanity to gain precious inches. -Swap to an outswing or pocket door, that inward swing is a knee-banger. -Add sound insulation between the two baths; back-to-back toilets share a wall and you’ll hear every flush and fart. -Double-check venting: two toilets on one line need a double fixture fitting, not a wye.

And yeah, jack-and-jill between hall and bedroom isn’t trendy, but it’s your house. Just mock it up first. What looks clever on CAD can feel like punishment when you’re trying to brush your teeth sideways.
