What is the best paint to use for a small bathroom with no ventilation

Benjamin Moore's AURA recieved the best reviews, although NOT many 'rave' reviews. Six months ago a man from castle Rock. Colorado (who called himself ThatBaldGuy) wrote a review that makes sense using ANY paint -- however not many folks do what he instructs, but they SHOULD:

"I have found Aura to be a fantastic product as long as you are aware that it doesn't work like other paints and I can affirm that almost every negative review I've seen indicates that it was being used like any other latex paint. Follow a few rules for using it and you'll have great success applying it and you'll love it. 1) "Self-priming" does not mean you can paint one coat over bare drywall. It means you won't have to prime over other colors, even when painting a light color over dark. Two coats of white will cover old black very well. 2) When cutting in ceilings, corners, baseboards, etc., do all of your cutting-in first and let them dry, then roll the walls. 3) It dries fast - so work fast. Once you start a wall don't stop. Don't take a phone call, get a cup of coffee, or take a bathroom break. 4) Use a good microfiber roller. You'll get outstanding coverage and end up paying about the same amount per square foot as with cheaper paints. 5) Do not thin with water, Floetrol, etc. If you want to thin it use Benjamin Moore 918, which is designed to thin Aura. I use 8 ounces per gallon because I do like my paint just a bit thinner. 6) And last but not least, do not overwork it! I've seen people roll, roll, roll over their paint once they've applied it. Put it on, go over once to even it out, then move on. I guess I was lucky enough to have purchased my first Aura from an excellent retailer who gave me tips for using the paint, and it really does work. I won't use any other paint in my house!"

Personally, I owuld consider using a mold killing primer, such as Zinsser or Kilz, And without ventilation you definitely would want to use a low-odor to NO odor paint over it . The following link discusses these paints and recommendations:

GOOD LUCK and thank you for helping us all to be more knowledgeable :)

New paint needs a clean, dry surface to adhere to. Mildew can prevent the new paint from properly sticking and can bleed through the new paint. Remove mildew with a sponge dipped in a solution of one part bleach to three parts water. The room should be well ventilated, so open a window or run the exhaust fan. Wipe down the surface with clean water and allow to dry before painting.

Satin is more durable and shinier than eggshell and is ideal for a bathroom. It's also easy to clean. Use it for the walls, ceiling, and even the trim, because many satin finishes are tougher than they once were. Semigloss is even tougher and a cinch to clean, and it can be used on the walls, ceiling, trim, and vanity if you don't mind a shinier look. A satin sheen draws attention to any imperfections on the walls—and semigloss does so even more—so prep them, trying to get them as smooth as you can.

Kiln paint for moisture and hire handy man to install ceiling vent that will save you $$ down the road😍

Thank you, Katty for this information. I'll definitely save it for the future.

there are low fume paints

kilz paint cover walls, but use a fan on yourself while painting, there is a non fume type similar to kilz and cheaper, ask for it at the hardware store
