America's Most Underserved Cities for Floating (2026)

The flip side of the Float Capitals: big American cities where you can barely find a tank inside the city limits. These are the 12 most populous US cities (200,000+ residents) with zero or one float center in our 664-center national directory — 3.0 million people between them. If you've ever thought about opening a float center, this is the market-gap list. Updated 2026-07-25.

The list

Top of the table: Honolulu, HI — 344,967 people, no float center. The biggest city with none at all is Honolulu, HI (344,967 residents — 12 of the 12 cities are at zero). Many are large suburbs inside major metros, which is exactly the point: the anchor city's centers are a drive away, and the local walk-in market is wide open.

Read it fairly: counts are within city limits. A resident of one of these cities may well drive to a neighboring town to float. "Underserved" here means no local center — not that no one nearby has ever floated.

Methodology: center counts from our continuously maintained national directory of 664 float centers (public business listings, filtered by a strict two-source evidence gate to genuine float / sensory-deprivation centers). City universe = incorporated places and consolidated city-governments with 200,000+ residents, US Census 2024 estimates; census names normalized to everyday names (Nashville-Davidson → Nashville) so no city is falsely flagged. Centers are matched to cities by the city name on their address. Refreshed with each re-crawl — a city graduates off this list the moment a center opens.
