Whats the best paint to paint bathroom?

It looks to me like it may already be wet behind the boards, due to the discolouration in a couple of areas.

If so, it will lead to troublesome problems sooner or later.

If the material in the tub surround and/or the material in the seams has not been rated for direct contact with water, unfortunately, no amount of painting will seal it so that it prevents seepage, mold growing, or rotting from occurring.

Oil base as it will not absorb moisture.

Sherwin Williams, go to a free standing store and get specific advise. Their personnel are trained to help with the best paint for an application. Unlike some stores where they just hire you and you get on the job training.

I agree, this is already showing water damage.

Why not install a vinyl cove base?

It can be bought in either 4’ pieces, 8’ pieces or a roll.

When installing it, use the proper mastic and seat it with silicone at the bottom edge or use tub-n-tile caulk.

I would really consider putting in a tub surround. That way no water at all would hit the bathroom walls.

I think a tub surround would be nice and you could pick any style.

If that's wood somebody did a patch job that will not last. There already is signs of damage there. You should replace it with something that is waterproof. For a temporary fix use an epoxy paint. It will last for a while until you decide what you want to do for a permanent repair.

You may need to see what's behind the wall boards before proceeding. It makes little sense to paint, only to later discover more water damage.

I would say the one that doesn't absorb moisture :)

Hello,

On the walls - Satin finish on the timber - Gloss Hope that helps!

I’d remove those trim pieces as no paint is going to ever seal out water enough. Either replace the backing with cement board and tile or cement board and a plastic trim.

Hi! There are materials that look like wood, but aren't that are waterproof and you won't have to paint. I would remove what you have, repair any water damage and then use a waterproof material and caulk well. It will prevent damage and maintenance will be minimal. Good luck and stay safe!

A surround would be just perfect for your tub area, easy to clean.
