How to create a bathroom tile texture?

Hi, I am currently trying to make a bathroom like room for the house in my horror demo. I have looked all across the internet and cannot find a video on how to create a tile like material for the bathroom floor. Could anyone possibly point me in the right direction of creating one?

That’s all I use.

As far as art tutorials though, I’m completely useless. Most things I’ve done artwise have been self taught.

There’s tons of methods, using photos, modeling/sculpting, or using a procedural texturing program like substance designer.
