FLEX Spas Phoenix

About

FLEX Spas Phoenix, located at 1517 S Black Canyon Hwy, Phoenix, AZ 85009, USA, is a men's-only bathhouse and spa facility. It offers various amenities for relaxation and social interaction, including a large hot tub/jacuzzi, a steam room, a dry sauna, a swimming pool, and a cold plunge.

The facility typically features a heated swimming pool, a hot tub/jacuzzi maintained at elevated temperatures (commonly 100-104°F), and a cold plunge pool designed for lower temperatures (often 40-60°F). Specific exact temperatures for the heated pool may vary, but are generally comfortable for swimming.

What are people saying (AI review summary)? Reviews present a mixed picture of the establishment. The staff consistently receives high praise for being friendly, helpful, and perceptive. Positive aspects noted include 'fun' experiences, plenty of dark mazes, and a relaxing sauna/steam room (when fully operational). However, significant concerns are frequently raised about the facility's condition and maintenance. Several visitors described the premises as run down, dirty, or featuring tattered seating, with specific complaints about splinters from wood fixtures, inconsistent steam, limited functional showers and bathrooms (including a broken urinal), and a non-operational pool. Practical details shared include the mandatory requirement for individual memberships and a locker or changing room (applicable to each person in a couple), the provision of protection, and that showers and saunas close relatively early (around midnight or 1 am). Despite these issues, some found the experience worth the cost and would consider returning if amenities were guaranteed to be in working order.

My previous rating was unfair, and revolved mostly around one experience. All things considered, a five star experience. Yeah, sometimes it’s busy, sometimes it’s not. You get what you give. It is a discreet location, can’t really see the parking lot and have to slow down to get into the place. Sometimes clientele are an issue but welcome to public spaces right?

Place was fun! I’ve always looked at the reviews and photos but have never gotten good info so hope this helps. 1. You must get a membership AND locker or changing room. 2. If you are a couple, each person needs a membership AND get a locker or changing room. 3. Plenty of dark mazes but are pretty tight spaced. 4. Showers and Sauna closes at midnight or 1am ish which was a big bummer. 5. 1 towel per locker or changing room available. 6. Protection provided. 7. Sauna (Steam Room) was super nice and relaxing Oh and I waited about half an hour in line but was totally worth it. $66 or something like that for a couple. (Small changing room + locker)

Was not a good experience, and not because of the people that were there, more because of the condition of the facility. Run down and dirty. I’ve heard about it for many years and never had the occasion to go, but now having been, I will never go again. Just thought I should let others know.

The staff was the standout. They were friendly and helpful and perceptive. Not as epic as the Flex in Cleveland but I like all the mirrored doors and clean with the right touch of sleaze. Certain parts were a bit too cold though

I was visiting from Chicago and had an available Monday so I decided to pass the time here. I am not sure I will do so again. Being a Monday afternoon I expected it to be somewhat slow which that was fine. I had hours to spare. I rented a medium room which was clean but a locker would have sufficed during these hours. I will say that the staff was very friendly! They were working and during my visit closed areas temporarily to give them a cleaning to be reopened right after. This I appreciated! While exploring I developed a couple splinters due to the wood fixtures that were in the dark. I understand the lighting situation but when having to navigate with hands it can cause issues. Although the steam room was cleaned the steam was not running consistently so it was like sitting in a damp room. There seemed to be only two bathroom stalls and one urinal in the establishment. The urinal itself was out of service. Perhaps there were more in other areas but none that I came across. The shower area had equipment in it I guess for repairs so only two of the showers were usable. Biggest sadness was that the pool was also out of service. The hot tub was accessible at this time however. Some of the public seating areas were tattered and torn. Sadly I was not by the time I left. If I could be guaranteed more (if not all) of the amenities would be in working order I would give this place another chance my next visit.
