I've had 3 liner quotes this week, all within $200 of each other. Based on that, I'd say it's very geographic dependent. They will charge whatever the market will bear. In my area, I'm paying $3600. This includes tear out/haul away of the old liner, new white plastic (skimmer plates, jets, drain), new light ring and filling divots on the pool bottom. They charge an additional $300 to fill it from the fire hydrant.
