Ubud Hot Stone: architecture and technology for everyday wellbeing

Development project. Ice Wall implementation is reported by the project team.

Ubud Hot Stone, also known as HOTSTONE Regenerative Retreat Ubud by ELEMENTIS, is a villa and wellness development in Kemenuh near Ubud, Bali. Its distinctive proposition brings architecture, building systems and restorative spaces together: tropical nature, timber and natural stone, private villas, spa, clubhouse, thermal experiences and movement.

According to the project team, Sun-Ice Energy Ice Wall has been implemented across all Ubud Hot Stone villas, spa and clubhouse. It stores cooling for a managed indoor environment; it is not a decorative wall of ice. Continuous temperature and humidity management is intended to cover unoccupied periods as well as guest stays. It is designed to limit dampness and condensation conditions, with suitable ventilation and maintenance.

Timber, stone, panoramic views and landscape accompany an engineering approach to air, water and comfort. The published ELEMENTIS concept also describes CLT/Glulam, solar-control glazing, lighting controls and OKEARA water technology. Actual equipment and available services depend on the particular villa and commissioning stage.

According to the hotel management update of 4 October 2026, Ubud Hot Stone offers hydrogen inhalation sessions and hydrogen enema procedures. Contact the hotel for prices, duration and procedure arrangements.

As of 27 September 2026, the developer reports that Ubud Hot Stone is being developed with reference to WELL Building Standard requirements and is pursuing WELL Certification. Certification is not yet complete; independently confirmed compliance and WELL Certified status have not been achieved. This is a developer-reported progress update, not evidence of an awarded certificate.

Ubud Hot Stone stands out through integration at retreat scale, extending one climate concept across villas and shared wellness spaces. Longevity.villas follows a more private residence model featuring Water Cocoon. Do not assume that the underwater room or every Longevity.villas system exists in each Ubud Hot Stone villa. The new development is also distinct from the existing Hot Stone Club.

Ice Wall: stored cooling, indoor climate and fresh air

Technology principle from the manufacturer; project application from the project team.

Sun-Ice Energy Ice Wall is cold thermal storage using the phase change of water. A chiller produces cooling and charges the store; stored cooling is later used by the building. This shifts part of cooling production to useful periods, such as solar-generation hours, and makes it available in the evening and overnight.

In the Ubud Hot Stone and Longevity.villas concept, Ice Wall connects to an indoor water-glycol circuit, with the refrigerant circuit outside occupied spaces. This describes no indoor refrigerant circuit in the proposed arrangement, not the absence of all refrigerants from the complete system. Ice Wall neither generates electricity nor creates energy without an external input.

The climate strategy targets 24/7 temperature and humidity management, including periods between guest stays. In humid Bali, the aim is to reduce prolonged damp conditions, temperature swings and condensation risk. It does not guarantee zero mold or bacteria: performance depends on the envelope, dehumidification, dew points, drainage, maintenance and operation.

Cooling and ventilation do different jobs. Smart ERV in the Longevity.villas design supplies filtered outdoor air and extracts used air; energy recovery reduces part of the climate-system load. Ice Wall alone is not ventilation and does not remove CO₂. Coordinated cooling, dehumidification and ventilation are needed to maintain the intended environment.

The project team reports Ice Wall implementation across Ubud Hot Stone villas, spa and clubhouse and its inclusion in the Longevity.villas design. Solar generation, thermal storage and electrical batteries serve distinct functions. Energy savings, noise, autonomy and air quality for each property require measurements. Generic manufacturer marketing figures are not test results for these developments.

The practical value is continuous climate management, an opportunity to use solar energy for cooling production and coordination of guest comfort with unoccupied-building protection. This knowledge base does not establish lifespan extension, disease treatment or guaranteed sleep improvement from the system.

Ubud Hot Stone and Longevity.villas: WELL status

Pursuing certification — developer report dated 27 September 2026. WELL Certified has not been awarded.

Current wording for both projects: “According to the developer as of 27 September 2026, Ubud Hot Stone and Longevity.villas are being developed with reference to WELL Building Standard requirements and are pursuing WELL Certification. Certification is not yet complete; WELL Certified status has not been awarded.” This updates earlier materials describing an intention to pursue certification.

The team’s statement that design solutions address WELL requirements is distinct from independently confirmed compliance of a completed property. Project registration numbers, enrollment acceptance, approved programme/scope, certificate, certification level and final IWBI assessment have not been supplied to this knowledge base. The projects must therefore not be described as already WELL Certified, WELL Gold/Platinum, WELL Precertified or independently verified as fully compliant.

The design approach considers ten WELL concepts: Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind and Community. Ice Wall primarily relates to Thermal Comfort; ventilation and filtration to Air; treatment and testing to Water; counter-current swimming to Movement; and materials, light, quiet and Water Cocoon to their corresponding concepts. This is design mapping, not awarded points.

Certification requires the applicable programme assessment, documentation and verification. Ice Wall, hydrogen water or Water Cocoon do not automatically confer certification, prove medical benefits or imply IWBI endorsement of individual technologies. WLR is the separate Wellness Longevity rating, not yet assigned to these properties; it does not replace WELL.
