You're Lucky. That Salesman did you a favor. My Salesman was nice, and we purchased. The initial job was just OK, but we were satisfied. But within a year the fixture didn't work. We were told that those fixtures have cartridges that aren't warranted. $300 to repair. Same year, all the caulk turned yellow. First they said we were using the wrong cleaner. We showed what we using and it is what they recommended. Then they said I needed to take pictures and send them in. Then the pictures weren't clear enough. Then I'd have to have someone come out to inspect, etc., etc. Long story made short, they won't cover it.
So count yourself lucky.
