How do I paint the bathroom ceiling over the bath?

Cover the tub wity a drop cloth

Also, make sure not to shower for at least 24 hours so the moisture doesn’t mess with the paint

See if this helps.

Cover and tape off everything not to be painted, drips happen! Use the absolute best paint you can afford, and don't forget to wash and prime the ceiling first.

There are special paints for bathrooms and high humidity, talk to the customer service to find the correct one if you’re concerned.

Use a mini-step ladder or step stool inside the tub and make sure it is on a non-slip rug or bath mat.

I used Zinzer's Perma-white on my bathroom ceiling. Perfect.

I've used Kilz Primer first, then paint with semigloss in your preferred color.

I did! That's why I suggested using a rubber bath mat! So you don't slip like I did!

Get the Rubbermaid mat with the suction cups - works really well to keep the step stool from sliding!

Just be careful Debbie! And enjoy your new bathroom!
