Spa opening and refresh planning for fitness–recovery–medical spa hybrids

Mark Mastrov, founder of 24 Hour Fitness, has unveiled Founders Club, a new fitness and wellness concept that combines a substantial strength training offer with recovery facilities, a medical spa, and spaces designed for working and socialising.

The announcement lands as more operators experiment with “all-day” wellness ecosystems—where gym, recovery and clinical-grade services sit side by side, and where the guest journey extends beyond a booked treatment slot. For hotel and resort spas, the significance isn’t that a gym brand added spa elements; it’s that the lines between fitness, recovery and med-spa programming continue to blur, pushing planning decisions upstream into design, scope and operational readiness.

Why the Founders Club format matters to spa operators

Founders Club is positioned as a combined model: strength training, recovery, medical spa, and non-treatment spaces for work and socialising. That mix signals a shift in what “wellness” is expected to contain within a single venue. For traditional spas—especially those embedded within hotels and resorts—this convergence increases the pressure to define what belongs inside the spa boundary versus what should sit adjacent to it as part of a broader wellness campus.

Practically, hybrid formats create competing requirements: quiet and privacy for hands-on services, higher throughput and more “drop-in” usage for recovery amenities, and a clinical sensibility and governance mindset around medical spa programming. When a concept is designed to support working and socialising as well, acoustics, circulation and guest wayfinding become core business considerations rather than finishing touches.

Scope definition: treatment rooms vs. recovery areas vs. medical spa

In hybrid facilities, the earliest planning risk is ambiguous scope: a venue can become overbuilt for one function and underbuilt for another. Mastrov’s format names three distinct service zones—fitness, recovery, and medical spa—each of which tends to drive different room types, adjacencies and operating rhythms.

For spa leadership teams, the key question is less “Should we add recovery?” and more “What is the operating model implied by the mix?” Recovery areas often rely on repeat, short-duration use; treatment rooms tend to be appointment-led; medical spa services may require a different intake process and back-of-house support. If these elements share reception, retail, consult rooms or wet areas, the planning team has to decide how to protect the experience of each without creating bottlenecks or confusing transitions.

This is where Spa opening and refresh planning becomes a management tool, not a design afterthought: it aligns treatment-room scope, equipment priorities and operating requirements to the specific concept mix before decisions become expensive to change.

Flow and “dwell time” become design variables—not just marketing ideas

Founders Club explicitly includes spaces for working and socialising, which signals an intent to increase dwell time. That has implications for resorts and hotels that are already balancing spa serenity with broader property energy.

If guests are moving between strength training, recovery and medical spa programming—and then staying to work or socialise—operators must consider how many “front doors” the wellness venue effectively has, how check-in is handled, and how circulation paths avoid unwanted cross-traffic (for example, guests moving from a high-activity fitness area into quieter treatment corridors). In many properties, the spa was originally designed as a contained environment. Hybrid concepts challenge that containment, which is why refresh projects increasingly touch not just finishes, but the fundamental guest journey and departmental interfaces.

Opening readiness: aligning vendors, staffing assumptions and timelines

Hybrid models also elevate opening complexity. Multiple zones frequently mean multiple vendor categories and a wider set of commissioning and training needs. Even without changing the physical footprint, a refresh that introduces recovery or medical spa elements tends to cascade into updated SOPs, treatment menu development, and revised pre-opening checklists—especially where guest flows or shared spaces change.

In this context, spa directors and GMs benefit from planning support that is explicit about priorities: what must be procured and installed early, what can be phased, and what operating requirements (from storage to turnaround rhythms) should be validated before the first soft opening.

Where STI’s spa opening and refresh planning fits

Spa Team International’s spa opening and refresh planning is designed to help owners and operators translate a hybrid concept into an executable scope. STI supports planning for treatment-room scope, equipment priorities, vendor options, operating requirements, and opening timelines—the practical backbone behind launches and renovations where the venue’s purpose is expanding beyond traditional spa boundaries.

As concepts like Founders Club put fitness, recovery and medical spa programming under one umbrella, the planning emphasis shifts to integration: ensuring that room count, adjacencies, and operational assumptions match the intended mix, and that the opening plan reflects the realities of a multi-zone wellness operation.
