The good news: spas want your money
Resort pools are capacity-limited amenities that come with the room, so they turn non-guests away. Spas are profit centers with appointment books, so they mostly do not. Nearly every major Las Vegas resort spa sells facility day passes to the public, and all of them sell treatments to anyone who books. The exceptions are a handful of the most exclusive spas that restrict non-guest day passes on peak weekends, and even those usually take a non-guest who is booking a treatment.
The practical upshot is that you can stay at a budget hotel and spend the afternoon at Qua, Canyon Ranch or Awana. Pair that with our cheap hotels guide and you have a luxury spa day at a fraction of a luxury hotel rate.
Three ways in
- Facility day pass. Pay a flat fee for the day, use the thermal areas, pools, steam, sauna, lounge and fitness center. No treatment required. As of 2026, roughly $40 to $100-plus depending on the spa and day.
- Treatment with included access. Book a massage, facial or body treatment and facility access for the day is usually included or discounted. This is the most common route and often the best value if you wanted a treatment anyway.
- Fitness pass. Some resorts sell a cheaper gym-only pass that includes locker rooms and sometimes steam and sauna but not the thermal suite. Useful for a workout, not for a spa day.
Always ask which areas the pass covers. "Spa access" at one resort means a full thermal circuit; at another it means the locker room and a whirlpool.
Who sells passes, roughly
As of 2026 the spas that most reliably sell facility day passes to non-guests include Awana at Resorts World, Qua at Caesars Palace, Canyon Ranch at The Venetian, the Spa at Aria, Spa Bellagio, Sahra at the Cosmopolitan, the Fontainebleau spa and the spas at MGM Grand, Mandalay Bay and Park MGM. The Wynn and Encore spas have historically limited non-guest facility access, especially on weekends, but take non-guests for treatments.
Policies change with occupancy and season. Call the spa or check its official page the week you travel rather than relying on any list, including this one. Our best resort spas guide describes what each facility actually contains so you know what you are paying for.
What a day pass costs and what moves the price
The range is wide because the spas are so different. A pass at a mid-tier resort spa with a whirlpool, steam and sauna sits around $40 to $60. The big thermal spas charge $60 to $100-plus for their circuits, and a few tier pricing by day of the week with weekend surcharges. Hotel guests at the same resort typically pay less or nothing with a treatment.
Some spas sell passes through third-party platforms alongside pool passes, occasionally at a discount and often with a daybed or lunch bundled in. Comparing the platform price against the spa's own rate takes two minutes and sometimes saves $20. As always, treat every figure here as approximate and check the official page.
The public bathhouses: an alternative
If what you want is hot water and heat rather than resort polish, Las Vegas has a few genuinely public options. Korean-style spas in the Chinatown and west-side areas offer day admission at a fraction of the Strip price, with hot and cold pools, dry saunas and scrub services, and they are open to everyone with no room key or resort fee. They are a short rideshare from the Strip and are covered in more detail in our treatments guide.
Downtown, a few hotels offer smaller spas with simpler pricing. They will not match Qua for spectacle, but for a $30 to $50 soak before a night on Fremont Street they do the job.
Timing: when the spa is actually relaxing
A thermal suite with twelve people in it is a different place from one with sixty, and the swing is entirely predictable. Weekday mornings from opening until around noon are the quiet window. Friday and Saturday afternoons, particularly during pool season, convention weeks and big event weekends, are the busiest, and some spas stop selling day passes altogether when they hit capacity.
If you can only go on a weekend, go at opening. If you are booking a treatment, ask for the first or last slot of the day and plan to arrive 60 to 90 minutes early to use the facilities while they are calm. Check the events calendar before you pick a date; a spa on a fight weekend is not a retreat.
What to bring and what to expect
Bring a swimsuit, because most co-ed thermal areas require one, and photo ID, because every spa is 18 and over and some check. Robes, sandals, towels, lockers, toiletries and hair tools are provided everywhere on this list. Leave jewelry and valuables in your hotel safe rather than the spa locker.
Expect a check-in process with a short health questionnaire, a tour if it is your first visit and a reminder that phones are banned in wet areas and lounges. The relaxation lounges usually have tea, fruit and water; some spas have a cafe or will bring poolside food in. Plan on two to four hours for a pass to feel worthwhile, and remember that automatic gratuities apply to treatments but not usually to the pass itself.
Mistakes non-guests make
- Turning up on a Saturday afternoon without booking. Passes sell out and treatment books fill days ahead.
- Assuming access is included with a treatment. It usually is, but confirm when booking; a few spas charge a reduced pass on top.
- Paying for the thermal circuit and using it for twenty minutes. Give it half a day.
- Forgetting that the pool is separate. A spa pass does not get you onto the resort's main pool deck; see our pool day pass guide for that.
- Bringing children. Nearly every spa is adults-only.
