Unvented bathroom peeling

Unvented bathroom peeling
Painted shower, tub area about 8 years ago and now it is peeling



Hope to vent later this year but need to paint before extended mother in law stay. Here is what I plan tell me if wrong please. Scrape all loose flakes off. Prime with oil base paint, Skim coat with dry wall mud, reprime with oil base and than use a good latex for color.
Reason for skim coat is to fill pits from where chips are coming off.

How old is the house? #1 reason for paint peeling in a bath rm is latex having been applied directly over oil base enamel [without a primer] Your plan sounds good just be diligent with removing any/all loose paint.

Wow, I'm surprised the paint held up eight years. I would scrape off the loose paint. Paint with an oil based stain blocking primer then apply a mildew resistant paint on top and the glossier the better.
I would not apply mud. Mud is just mud. It dries and hardens but it readily absorbs moisture and when it gets wet it returns to mud. The mud won't have good adhesion to a painted surface. It will expand and contract with humidity/moisture which will cause trouble with the paint. And worst is if water vapor makes it through the top coat of paint and starts accumulating in the mud over time until it becomes mud behind the paint.
Also, loose the hanging rack attached to the shower neck. The fitting in the wall and especially the thin walled neck is not designed to carry the weight of a rack of bottles. When loaded they can break the neck off in the wall. Or, someone bumps it and it slides down the neck, hits the shower head breaking it off... or it breaks off the neck inside the wall.
If that rack is something you've just gotta have locate a stud in the wall above the tile. Run in a long stainless steel screw and leave a couple inches protruding or attach a bath robe hook to hang the rack.

I would replace oil based paint in your plan with oil based primer. Additionally, I would make sure the top coat is a kitchen and bath rated paint.

House 40+ years and I would guess latex over oil base. Only reason for skim coat is to fill chip depressions, Very noticeable. Rack already gone, Thanks ALL

Use a setting type compound like Easy Sand 20 minute to fill in your cracks. It dries by chemical reaction and is not affected by moisture. Comes in a powder, mix to regular mud consistency and then work fast, as it will set up in your pan before you get it on the wall.

While I often use Durabond to speed things up I don't believe regular j/c will present a problem as long as it is primed well and top coated with latex enamel.
40 yrs ago most of the well painted houses still used oil base enamel on the bath walls/ceilings. Latex enamel on walls was just starting to get used by a few.
