No home died from simple. You do NOT want to emphasize powder room or closet doors.

get a two panel for all and be done. Please. Save money to make the inside of the powder room appealing. A great paper, a wall color.....art......etc.

If you want the closet doors to disappear in favor of the slightly more important powder room? Paint the closet doors/trim casing same as wall color, with only a finish change to the paint.

All doors/cupboards should match..be the same..NEVER EVER put a barn door on a bathroom!!!!!

Matching and please no barn door on a PR

The barn door would have an unfortunate privacy issue. And yes, doors are nicer when they match.

Here are 1,2 &3 panel Shaker style doors. The interior doors you select should complement the architecture of your house.

Thoughts on pocket doors for powder room and closet vs normal swing. Both doors are in the entry area.
