I have a whirlpool tub side covering made of cultured marble, or so I believe. I need to trim it slightly to fit back under the the tub after re-tiling the bathroom floor.
It has no markings or writings, so I’m not positive about the material. How can I determine what it is, and then the best way to cut it?

What does the back look like.
If it is flat caulking looking them it is cultured markble.
If it has a finishes similar to the front, but maybe not as polished or more polished them it is a solid surface material.
SS can be cut with a carbide blade.
I think that cultured marble can also, but way for other response.
Cultured products are poured like cake batter. The flat panels are (usually) poured on a giant cookie sheet, so the face and four edges are finished. The back will show bubbles and a very non-smooth surface.
Carbide won't last long. Use a diamond bladed in a side grinder, or possibly a abrasive cutoff blade. Be prepared for lots of dust.
I did a job for a customer ... very large L-shaped bathroom vanity with 2 integral sinks. they were getting ready to sell, and the real estate agent said the small cracks around the drains would be a problem. Rather than a whole new top, they paid me to cut out the bowls and fit in new drop-in bowls. Looked good when it was done. I quoted a price that I thought would make me a bundle of money. Should have walked away form that job. Went through several carbide blades before hitting on the diamond. And what an incrfedible mess.
I'm sorry, I thought you wanted it done the right way.
You can cut a nice line in cultured marble with an angle grinder and a thin metal cutting abrasive disc. Back cut it a bit and fine tune with a belt sander. Using a carbide blade in a circular saw will cut it, but chips are a good possibility.

I owned a cultured marble shop for quite a few years, as one other posting said "if there appear to be bubbles on the back side (and sometimes they are partially ground off) it is cultured marble. We used masonary blades in all of our saws. Cut the edge that is not going to be seen, the finish on the cm is a gelcoat that is sprayed in the mold and is almost impossible to replicate.
