Yeah, the bath/shower panels come in a variety of colors and styles like plain, textured, tile patterns. You can get PVC edge trim and bead to go with it. Only caution to those is they need to be adhered to a substrate, otherwise over time they can bubble/bow and look tacky. For something a bit more durable a synthetic sheet like avonite or corian would look great and is pretty sturdy. I've used it for shower walls, tub surrounds and counters in my S&B houses.
Whatever you tore out of there would be an option if it's lasted since 1965.
