NB. I'm a total noob when it comes to home improvement so it's both fine and preferred to answer me like if I'm a retarded banana. Understanding my ignorance I have a lot of respect for the competence needed and I'm afraid of making choices that I'll regret later on. (I have a guy to help me but I'd like to understand what's going on and learn myself.)
In my hall, I'd like to put tiles and I can't decide between different parameters (specified below) because I don't understand the implications of the choice. Asking in the store lead to recommendation that is suspectedly pricey.
Color: I'd go for dark/black because the dirt won't show as easily as on bright tiles.
Filling: I'd go with bright one (but not too bright) to create some contrast and enhance the grid pattern.
Size: Here I'm stuck. What are pros and cons of large/medium/small tiles?
Format: Here I'm stuck. What are pros and cons of squares/rectangles?
Texture: Here I'm unsure. Personally, I'd prefer some uneven-ness but not abrasive. What is downside of that, if anything?
Pricing: I've been told that the price range is due to quality. But I'm not sure how it works. It's not that I'll be riding a horse with horseshoes on it. How fragile is a tile of lower quality?
The last item is the most confusing. I prefer to lower the cost, of course, but I definitely don't want to go and cheap myself into problems. Please advise. (The fact is that the cheapest tiles they had is around 10$ and others are around 25$-120$. And I kind of liked the cheapest the best...)
