How do I paint a bathtub ?

there are tub paints available in a kit form, I don't recall the brand, rustoleum might be one, but there are others.

There are professionals who do this. They should guarantee their work.

Again: Rustoleum Tub and Tile resurfacing kit. They come in White or Almond.

The RustOleum kit gets my vote. 2 person job, follow directions exactly, wear a respirator and vent the area as much as possible.

Can u up date this bathroom suite cant effort new at moment bath plastic sink pot and toilet sistent plastic

Don't do a Do-It-Yourself tub re-glaze. We purchased a home where the master bath had a DIY tub re-glaze and, while it initially looked great within a year it peeled off.

Hi Mary, your best bet is to use a paint that's designed specifically for shower trays and that's resistant to harsh detergents. . Your local hardware should be able to guide you. I have heard great things about RustOleum's Tub & Tile kit, but I've only seen it in white. Most of the work will go into prepping the bathtub, but this video will guide you through the process - https://www.youtube.com/watch?v=m9m1kBzOjhI
