Pool resurfacing cost depends on more than pool size
Square footage matters, but it is not the whole price. The current finish, prep required, selected material, tile or coping issues, drain covers, steps, benches, access, and startup requirements all affect the final number. A simple pool with clean access and predictable prep is a different job than a pool with loose plaster, staining, damaged tile, and tight access through a side yard.
Be careful with any page that gives a number before anyone understands the condition of the surface. Orlando pool resurfacing is high enough ticket that guessing helps nobody. A useful quote should explain what is included, what could change, and what will be confirmed before scheduling.
Cost factors to ask about
Ask whether draining, prep, surface removal, bond coat, material, startup, cleanup, and return visits are included. Ask whether tile, coping, lights, drain covers, or structural cracks are separate. Ask how weather affects timing and what happens if hidden surface problems show up after the pool is drained.
The cheapest quote is not always wrong. The highest quote is not always better. What matters is whether the scope is clear enough that you know what you are approving.
