My Grandma's was a 1930 semi and it had a tiled floor - red white and black mosaicy type tiles very similar to victorian ones, as well as wood panelling, and a plate rack around the top.
I had an aunt lived in one, and the ground floor was cement coated with what, in hindsight, must either been lots of Cardinal polish or red paint. Linoleum was laid over the top and rugs and runners on top of that.
