Nice work. I also recently bought a cheap Harbor Freight tile saw and tiled a shower in an ugly bathroom in one of my rentals. I was slow, but the result definitely turned the bath from a detraction to an asset. I see tile as very useful in rental properties since it is durable, attractive, and long lasting.
I used the small (1 inch) 'antique' black and white hexagons on the floor of the shower. Cutting those things with the saw was a bit of a trick.
