Home / Products / Cold Plunges / Upright Cold Plunges / CT15 1 Person Thermowood Upright Cold Plunge
CT15 combines an Upright cold-plunge format with Thermo Spruce + 304SS construction. At Ø960 × H1030 mm externally and Ø900 × H920 mm internally, it is the larger of HACHILL’s two Upright cold-plunge models.
The listed setup includes inlet, outlet and drain connections together with an insulated cover, step and internal seat. CT15 is designed for use with an external cooling system, allowing the cooling equipment to be selected for the installation and operating requirements.

Product Setup
Inlet, Outlet, Drain, Insulated Cover, Step, Internal Seat
CT15 is specified with a step and internal seat, making entry arrangement and surrounding circulation part of the site plan.
Cooling temperature, capacity and recovery performance depend on the external cooling system selected for the project.
Allow space beyond the tub dimensions for entry, drainage, water connections, cooling equipment and routine service access.
CT15 uses a Ø960 mm circular footprint, so the installation should be planned around the full diameter rather than treated like a rectangular piece of equipment. The Ø960 mm dimension defines the tub envelope; the completed installation also needs room for the user, step, cover, plumbing and cooling equipment.
Plan the step together with the approach direction, clear standing area, wet exit, nearby walls or fixtures and cover movement. The internal dimensions of Ø900 × H920 mm provide a reference for layout and the internal seat arrangement.
Compared with CT12, the additional diameter matters most in tighter wellness rooms, recovery areas and other space-constrained layouts.
CT15 differs from the stainless CT12 through its Thermo Spruce + 304SS construction. For buyers choosing CT15 for the wood-finished appearance, the material choice should be considered together with the wet-area environment and maintenance expectations.
Thermo Spruce + 304SS gives CT15 a different material and visual character from the all-stainless CT12.
Allow practical drainage, drying and access around the tub where repeated water exposure is expected.
Outdoor, coastal or otherwise exposed installations should be reviewed for the actual environment, maintenance expectations and complete equipment package.
Plan routine cleaning and inspection so the Thermowood finish and surrounding wet area remain accessible after installation.
Use these product and application views to review the Thermowood finish, insulated cover and overall form. Application scenes are illustrative and should not be treated as delivered-project references or performance evidence.
CT15 provides inlet, outlet and drain connections. Plan the tub position so these connections remain practical to reach and connect.
The chiller, cooling capacity, temperature control, pump, filtration, sanitation and electrical requirements depend on the system selected for the application.
Allow space for the cooling equipment, connecting pipework, drainage and any ventilation required around the selected equipment.
Keep the completed installation accessible for routine inspection, cleaning and service of the tub connections and cooling equipment.
CT15 is a strong candidate when Upright entry is preferred, the Ø960 mm tub envelope fits the site, the step works with the intended access, Thermo Spruce + 304SS suits the design brief and there is suitable space for the water connections and external cooling system.
CT12 is the closest alternative when the project should remain Upright but needs a smaller-diameter model with 304 stainless-steel construction.
If vertical entry is not preferred, compare the Laydown range. CT16 and CT26 keep a Thermowood material direction while changing the body format.
Use these adjacent products when the project needs a smaller Upright footprint or a different body format.
Once CT15 fits the product and site direction, send the quantity, destination market, intended application, available installation area, doorway or delivery constraints, entry and surrounding-space requirements, indoor or outdoor context, cooling equipment already selected if any, water and drainage information, OEM or branding requirements and document needs.
The quotation can then define the CT15 configuration, supplied accessories, cooling-system scope and project-specific requirements.
