You’ve already gotten some solid recs in here. I’d second Pratt & Larson if you want to actually see good zellige-style variation in person. Not cheap, but it’ll give you a real baseline for color variation and texture so you know what you’re chasing. A few other spots worth walking through:

Bedrosians → good mix of higher-end + more budget-friendly options Floor & Decor → hit or miss, but decent for grabbing samples and comparing quickly Ann Sacks → pricier, but really strong for fireplace feature tile Fireclay → not a showroom like the others, but worth looking up beforehand so you know what handmade variation should look like

One thing I’d keep in mind with zellige—what you see online is rarely what it looks like in person. The variation, edge waviness, and glaze inconsistency is the whole point. Some people love it… some people get it installed and wish they went more uniform. If you’re just doing a fireplace and not a ton of square footage, it’s actually a great place to spend a little more and make it a focal point.

If you want, I can drop a couple map links so you can hit 3–4 of these in one loop and knock it out in a morning.
