Samui Fitness Lab, Lamai: Classes and 24/7 Gym (2026)

Overview

Samui Fitness Lab is a training facility in Lamai, about 5.3 km from Chaweng as the crow flies, with coached CrossFit and HYROX sessions and a separate air-conditioned strength gym. It suits visitors who want either group coaching or independent lifting. As of October 2026, one class or an open-box visit during staffed hours costs 600 THB (~17 USD).

The useful distinction is between the main training box and the separate gym. You can choose a class-focused pass, gym access or an all-access option, rather than pay for the same arrangement regardless of how you train. Showers, lockers, water and parking make the facility practical for a standalone workout between other plans. The gym’s own website describes two of its coaches as CrossFit Games athletes. Pick the class date in the booking calendar on the drop-in page before you set out, because class start times are shown by date.

Key takeaways

• Advertised coached sessions last 60 minutes, as checked in October 2026.
• The separate strength gym offers 24/7 access with an eligible pass.
• Weekend staffed hours finish at 16:00, as of October 2026.
• The seven-day class pass costs 2,250 THB (~64 USD) and excludes the separate gym, as of October 2026.

Key Facts

Training and Facilities

Choose Samui Fitness Lab for coached CrossFit or HYROX if you want a session led by a trainer. Choose the separate strength gym if you want to follow your own programme in air conditioning. The operator welcomes beginners through experienced athletes, with advertised classes lasting 60 minutes.

The main box also offers independent open-gym training. That matters if you already have a workout planned but want access during staffed hours rather than a coached session. The drop-in page describes open-box space as available even while classes run. Ask where to train when you arrive so your independent workout fits around the group session.

The separate gym has a different access arrangement. Its 24/7 offer is useful if staffed opening times do not fit your day, but the class pass does not include it. Check that your chosen pass activates the facility you intend to use before heading there outside reception hours.

Showers and lockers let you change after training. Water and on-site parking are also listed. For a wider look at independent weights rooms and coached training, read Gym Koh Samui; the distinction between those two kinds of visit matters more here than the gym’s name alone.

What Does Samui Fitness Lab Cost?

Samui Fitness Lab’s visitor prices separate classes and main-box access from the air-conditioned gym. Start by choosing the space you need, then the length of pass. The following official tariffs were checked in October 2026; the gym-only figure is advertised as a starting price rather than a single all-purpose pass.

The longer class passes exclude the separate air-conditioned gym. If your plan mixes lifting there with coached sessions, compare the all-access options rather than assuming that a longer class membership covers both spaces. A longer stay changes which tariff is relevant, but it does not remove that access boundary.

For comparison, the existing BXB Fight Lab page lists a single class at 400 THB (~11 USD), a day pass at 600 THB (~17 USD) and a week at 2,700 THB (~77 USD), checked September 2026. BXB combines combat sports with strength facilities. Compare the training format as well as the price: those passes buy a different kind of training day.

Hours and Class Planning

Samui Fitness Lab’s staffed hours are Monday-Friday 07:00-19:00 and Saturday-Sunday 08:00-16:00, as of October 2026. Use those windows for a staffed-hours open-box visit. For a coached workout, check the actual class slot separately; a building being open does not give you a class start time.

Class start times are shown by date in the booking calendar on the drop-in page. Contact the gym with your preferred date and training type before travelling for a session, especially if your holiday leaves only one chance to train.

The official drop-in page advertises free cancellation up to two hours before a session, checked October 2026. Read the terms attached to the pass you select and keep the confirmation. The site’s registration flow manages bookings through a member account, so allow for that step when arranging your first visit.

Is Samui Fitness Lab Worth It?

Samui Fitness Lab is worth considering if you want CrossFit or HYROX coaching in Lamai, or a separate air-conditioned gym with access outside staffed hours. Skip the class pass if your whole plan is independent lifting in that separate gym. The access split is the main purchasing decision.

Beginners have a stated welcome rather than a requirement to arrive as experienced CrossFit athletes. Tell the gym what you have trained before when asking about a class. Someone following an established lifting programme can instead choose independent gym access without building the day around a coached workout.

The strongest reason to choose this facility is the choice of training environments. The main caveat is that bookings go through a member account, so set that up before your first visit. If a particular coached workout is the reason for your visit, get the slot confirmed first. The Samui sport directory covers other ways to keep active on the island.

FAQ

Can beginners train at Samui Fitness Lab?

Yes. Samui Fitness Lab advertises coached sessions for beginners through experienced athletes. Explain your experience when contacting the gym and ask which session fits your level. If you want instruction, choose a coached class rather than assuming an independent open-box visit includes the same help.

Yes. Samui Fitness Lab’s separate air-conditioned strength gym offers 24/7 access with an eligible pass, as of October 2026. Arrange access before arriving outside staffed hours. The main-box class pass and the separate gym pass cover different spaces, so check the pass description before paying.

No. Samui Fitness Lab’s seven-day class pass covers classes and main-box open gym, excluding the separate air-conditioned strength gym, as of October 2026.
