24 Hour Fitness

📍 2900 Iris Ave, Boulder, Colorado, 80301

This gym provides sauna and steam room facilities for heat therapy and relaxation, but gym members report significant and recurring concerns regarding their condition. The sauna and steam room are frequently described as filthy, with unpleasant odors indicating a lack of regular cleaning. A serious incident involving a chemical burn from the jacuzzi is noted, where members report staff knew the water chemistry was unsafe but failed to post warnings or restrict access, leading to injury and damaged swimwear. General pool and jacuzzi chemical imbalances are a repeated issue, with the chemical smell sometimes permeating the gym air. Beyond the wellness areas, the facility offers a wide variety of equipment including racks, weights, machines, and an indoor basketball court, alongside a pool and hot tub. The atmosphere receives mixed feedback; some members praise a positive community and friendly, helpful staff like Dorian, Charolette, Mia, and Sadie, while others criticize poor management, unhelpful responses to issues, and shady contract practices during sign-up. Cleanliness is inconsistent, with reports of sticky equipment, dirty floors, and worn-out machine cables posing safety hazards. A notable point of contention is the operating hours, with members reporting the gym frequently opens late or has closings, contradicting its "24 Hour" branding.
