Wellness Amenity ROI: How to Build the Investment Case
Wellness amenity ROI for hotels and estates: a simple payback model, two worked scenarios and the metrics to track before you commit capital.
The question I hear most at the start of a wellness project is some version of this: is it worth the investment?
It’s a fair question. Wellness amenities carry real capex, ongoing operating costs, and the staffing and programming needed to perform at a luxury standard. “Our competitors have one” isn’t a business case, yet in my experience it is often the only one on the table.
The short answer is that wellness amenity ROI is real and measurable when three things hold:
the facility is sized to demand
it is built around one experience done well
it is programmed to be used
Projects fail on sequence: the facility is built first and the revenue case is written afterwards. This article sets out how to build that case before capital is committed, with two worked scenarios and the metrics that show whether it’s working.
A small build that paid back in under 20 months
A 55-key coastal hotel we worked with converted an underused meeting room into a recovery lounge with a six-seat sauna and a single cold plunge. An adjacent storeroom became a compact strength studio. The build was modest and the programme was simple: three short sessions a day, plus a day pass for local guests at a competitive price.
Within two quarters the results were clear:
ADR rose by an average of R210.
Shoulder months began booking earlier.
Post-session food and beverage created a revenue line that hadn’t existed before.
The build paid back in under 20 months.
It wasn’t the largest or most elaborate facility in its market. It was the most consistently used, because it was designed to be simple to run and programmed for the guests that property actually attracts. That principle runs through everything that follows.
Where the return comes from
A wellness amenity earns its keep through five commercial levers. Knowing which ones matter for your asset changes how you size and programme it.
Room rate. In most of the hotel models we build, the rate line carries the case. A wellness offer guests value supports a higher ADR, and that uplift is earned on every occupied night. RLA Global’s latest wellness data points the same way: hotels with smaller wellness operations increasingly compete on room rate, while those with large ones lean more on non-room revenue.
Occupancy. A well-positioned offer gives guests a reason to choose your property over a comparable one, and it can strengthen shoulder-season demand. Wellness travellers are also a high-yield segment. The Global Wellness Institute found that international wellness tourists spent 41% more per trip than the typical international tourist in 2022.
Ancillary revenue. This covers treatments, day passes, retail and post-session food and beverage. Where there is a strong local professional market, off-peak day passes can add revenue for very little extra operating cost.
Length of stay. Guests who use the facility have one more reason to stay an extra night. Across a year of occupancy, even a small increase in average stay is a meaningful revenue line.
Resale and membership value. For estates and residential developments, a credible wellness offer can support levies, membership fees and resale values, but only if the facility is actively used. Quantify this locally, using agents’ comparable sales, rather than relying on industry averages.
How to model wellness amenity ROI
The structure of the model is simple. What makes it useful is replacing assumptions with real numbers from your market and property.
Annual cash uplift = (ADR uplift × rooms × occupancy × 365) + occupancy contribution + net ancillary revenue + membership or resale uplift where relevant − incremental operating cost
Payback period = total capex ÷ annual cash uplift
Three cautions keep the model honest:
Attribution. Not every rand of ADR growth belongs to the wellness facility, so test the uplift you assume against your competitive set and guest feedback.
Simple payback is incomplete. It ignores financing, depreciation and replacement cycles, and boards and lenders will usually want NPV or IRR alongside it.
Run more than one case. Model a conservative case, not just a base case.
As a planning benchmark, I look for payback of 18 to 36 months on compact, well-used wellness amenities in the luxury segment. Larger, more complex facilities take longer. Beyond about 48 months, the investment needs a clear secondary justification to be commercially defensible: brand positioning, competitive necessity or residential sales.
Two worked scenarios
These are illustrative, not forecasts. Replace the figures with your own market data and they become the basis of a board paper.
Boutique hotel, 40 keys
The build: a compact gym, a sauna with cold plunge and a recovery lounge, with capex of around R3.5 million.
Base case:
An ADR uplift of R250 at 65% occupancy adds about R2.4 million a year from rate.
Add R80,000 a month in net ancillary revenue and subtract R55,000 a month in operating cost.
The annual cash uplift is about R2.7 million, giving a payback of around 16 months.
Conservative case:
Cut the ADR uplift to R150 and the rate contribution falls to about R1.4 million.
The annual cash uplift falls to about R1.7 million, giving a payback of around 24 months.
The base case looks exceptional. The conservative case still sits comfortably inside the benchmark range. That gap is exactly why both belong in the board paper.
Coastal estate clubhouse
The build: a members’ fitness studio, sauna and outdoor vitality pool, with capex of around R5.2 million.
The numbers:
Membership and levy uplift, net of cost: R180,000 a month.
Event hire and day-guest revenue: R50,000 a month.
Incremental operating cost: R90,000 a month.
The annual cash uplift is about R1.7 million, giving a payback of around 37 months. That is acceptable for a residential asset, where the main return is resale value rather than operating income.
In both cases, the critical variable is utilisation. These numbers depend on a programme that drives steady use, not a facility that photographs well and sits empty between 10am and 4pm.
Design decisions that protect the return
Most of the ROI problems I see are not programming or staffing problems. They are design decisions locked in before the first guest arrives: facilities sized beyond demand, placed away from natural guest circulation, or laid out so they need more staff than the revenue can support.
Specify for efficiency from the start, with heat recovery, zoned controls and proper insulation in wet areas. In markets with an unreliable grid, such as South Africa, treat backup power as part of the base specification.
We cover the costliest of these errors in hotel spa design mistakes. Where the site allows, an outdoor fitness space can deliver part of the offer for far less capital.
Pricing and programming that drive use
Hotels. The baseline is access included for all guests or tiered by room category, plus a day pass for local guests during off-peak hours. In our experience, bundles outperform à la carte pricing on both uptake and margin, for example sauna, cold plunge and a 45-minute recovery session at a single price. Short daily sessions, such as morning mobility, guided contrast therapy or breathwork, cost little to staff and drive steady use.
Estates and private clubs. Include access in the levy and offer coached sessions as a premium tier. Quiet hours, youth hours and seasonal programming build the community that turns a facility into a reason members stay.
Place. Wherever possible, build the programme with local practitioners and the landscape around you. It gives guests something they can’t find at the next property, and it costs less than equipment.
Retail. Retail is often an afterthought, and it shouldn’t be. Recovery products, drinks and light post-session food are high-margin lines that need almost no extra operating cost, provided they sit where guests leave.
The metrics that show whether it’s working
Track weekly, review monthly, adjust quarterly.
Core indicators:
ADR and RevPAR against your competitive set
capture rate (the share of staying guests who use the facility)
ancillary spend per occupied room
day-pass revenue
Secondary indicators:
energy and water cost per guest use
maintenance downtime, which is often the earliest warning of a specification problem
As a rule of thumb, a capture rate below 30% of staying guests points to a utilisation problem that programming can usually fix. Energy cost per use running well above the model points to a specification or operating problem, which calls for a different conversation.
A 90-day plan for owners at the evaluation stage
Weeks 1 to 2: demand validation. Review guest feedback and OTA filters for wellness mentions. Assess what comparable properties offer and at what price. Survey guests or residents on the amenities they want and what they would pay. This tells you whether the demand case is real or assumed.
Weeks 3 to 6: concept and costing. Choose one hero experience, ideally rooted in what the site already offers, and plan to deliver it well rather than three delivered adequately. Develop block plans, plant specifications and finish schedules. Build the capex and operating model with conservative, base and optimistic scenarios, so the board paper is stress-tested before it is presented.
Weeks 7 to 11: procurement. Shortlist suppliers with local service agreements and access to spare parts. Specify energy- and water-efficient plant from the outset. Choose finishes that clean quickly and can be repaired locally.
Weeks 12 to 13: launch readiness. Train staff on delivery and upselling. Integrate booking and waiver forms with your PMS or member app. Run a soft opening with local partners to generate early reviews before the commercial launch.
What this means for owners
Write the revenue case before the design brief.
Model a conservative case, and test the ADR uplift you attribute to wellness.
Choose one experience you can deliver well.
Decide the programme and staffing before you build.
Track capture rate and cost per use from the first month.
If you are evaluating a wellness investment and want a numbers-first concept for your property, a strategy session produces exactly that: a commercial model, capex ranges and a 12-month activation plan.
FAQs
Is a sauna or a steam room the better investment?
For most properties, a sauna. Saunas are simpler to run, need less maintenance and typically pay back faster. Steam rooms suit certain guest segments but carry noticeably higher ongoing maintenance. Where operational simplicity matters, a sauna with a cold plunge usually performs better commercially.
We don’t have space for a full gym. Is wellness still worth it?
Often, yes. A compact recovery lounge with a sauna and cold plunge can be a stronger investment than a full gym. Operating costs are lower, programming is simpler, and day-pass and ancillary potential is often higher. The hero experience doesn’t need to be large. It needs to be excellent.
Can these returns be modelled for a residential estate?
Yes, but the model works differently. For residential developments, the main return drivers are resale value and levy or membership revenue rather than ADR and ancillary spend. The principle is the same: the facility needs a clear commercial case, not just a design brief.
When should we bring in independent advice?
Before capex is committed. Independent commercial input is worth most at concept and costing stage, while the decisions that will shape the next decade of performance are still open. After construction, the options narrow and the cost of correction rises.
