In this smartmak cold plunge tub 1hp review, we look at a dual-purpose immersion unit designed for recovery routines. The tub combines a 2-person rectangular basin made from Canadian red cedar and internal stainless steel with a separate 1 HP chiller. This setup allows you to adjust water temperature between 37 and 107°F. You also get built-in filtration, UV purification, and ozone generation to maintain water quality. The unit features WiFi control for remote adjustments. It arrives as a complete system where you simply connect the chiller to the tub and fill it with water to begin using it.

What stands out

  • Double-walled construction using Canadian red cedar and stainless steel prevents wood corrosion.
  • 1 HP chiller provides 2405W of cooling power and 3600W of heating power.
  • Temperature range spans from 37°F to 107°F for both cold and warm baths.
  • Integrated WiFi control lets you manage settings from your phone.
  • Built-in filter, UV rays, and ozone system keep the water clean automatically.

Who it fits

Good fit for

This unit suits users who want a dedicated recovery station in their home or garage. The 2-person rectangular design fits well in spaces where you need room for multiple users or longer bodies. The chiller’s wide temperature range makes it useful for both ice baths and warm muscle relaxation. If you prefer not to assemble complex wooden structures, the plug-and-play chiller connection saves time. The ETL safety certification adds peace of mind for indoor use near living areas.

Who should skip it

You should look elsewhere if you need a compact, portable tub for travel or small balconies. The 80-inch length and 38.5-inch height require significant floor space and ceiling clearance. The chiller is a standalone unit that needs to be drained after use to prevent freezing, which adds maintenance steps. If you want a fully self-contained all-in-one unit without external plumbing connections, this separate chiller design may not fit your setup. The rectangular shape also limits movement compared to rounded options.

Verdict: The Smartmak offers a robust, spec-heavy cold plunge system with strong heating and cooling capabilities. It is best for users with the space and maintenance willingness to support a dedicated immersion tub.

Key specs explained for this tub

Material: Canadian red cedar and stainless steel

The exterior uses Canadian red cedar, which provides natural durability and a pleasant scent. The interior lining is stainless steel, preventing wood rot and corrosion. This combination keeps the structure sturdy while protecting the wood from water damage. You get the look of timber with the hygiene of metal. It is a practical choice for long-term outdoor or indoor use without frequent maintenance.

Dimensions: 80 x 33.5 x 38.5 inches

The tub measures 80 inches in length, 33.5 inches in width, and 38.5 inches in height. These dimensions accommodate a 2-person rectangular shape. The length allows most adults to stretch out comfortably. The width and height provide adequate water depth for immersion. You should verify your space fits these measurements before purchase, as the footprint is substantial compared to smaller plunge pools.

Control Type: WiFi

You can manage the chiller settings remotely through a WiFi connection. This allows you to adjust temperatures or monitor the system without standing next to the unit. It adds convenience for checking status from inside your home. This feature is useful for setting up sessions in advance. It distinguishes this model from basic units that require manual panel adjustments for every change.

Seating Capacity: 2 Person

The basin is designed to comfortably seat two adults. This capacity suits couples or friends who want to share a recovery session. It offers more space than single-person units, which are often narrower. The rectangular shape supports side-by-side positioning. You should consider this size if you plan to use the tub frequently with a partner rather than alone.

Design and Build Overview

The Smartmak tub uses Canadian red cedar for the exterior and stainless steel for the interior lining. According to the listing, this combination prevents wood rot while maintaining a natural scent. The rectangular basin measures 80 inches in length, 33.5 inches in width, and 38.5 inches in height. This footprint accommodates two people comfortably. You can also choose from rounded or elliptic shapes if your space requires a different layout. The stainless steel internal shell ensures durability and simplifies cleaning. It keeps the cedar from corroding over time.

You control the unit via WiFi. This allows you to adjust the temperature from 37 to 107 degrees Fahrenheit remotely. The chiller includes a built-in filter and UV light to maintain water quality. You do not need to assemble the tub. You simply link the chiller to the basin and fill it with water. The chiller unit features wheels and handles, making it easy to move around. It weighs enough to require stable placement on a flat surface.

The unit carries ETL safety certification with an anti-leakage setting. This feature automatically cuts power if a leak is detected. You must ensure the ambient temperature stays between 32 and 113 degrees Fahrenheit. If the environment is too cold, the internal components may freeze. You should drain the chiller after use to prevent cracking. The finish is a natural red cedar color. This design fits well in garages, patios, or dedicated recovery rooms where you need a sturdy, low-maintenance structure.

Setup and everyday use

Setting up this unit requires minimal effort. The listing states that assembly is not needed. You simply link the chiller to the cold water bathtub. The chiller features wheels and handles, allowing you to move it easily into position. When connecting the conduit, you must pay attention to the water inlet and outlet holes. Ensure the tubes are smooth and installed according to the instructions to prevent flow issues. The chiller operates within an ambient temperature range of 32 to 113 degrees Fahrenheit. If the surrounding temperature drops too low, the cooler may freeze, potentially causing the machine to jam. Daily use involves filling the tub with water. The control type is WiFi, letting you adjust settings remotely. You can set the temperature between 37 and 107 degrees Fahrenheit. The cooling power is 2405 watts, while the heating power reaches 3600 watts. This range supports both cold plunge and warm soak routines. The unit includes a built-in filter and UV rays to keep the water clean. You should clean and replace the filter element in a timely manner. After use, you must drain the water inside the cooler to prevent internal storage from freezing and cracking. This step is crucial for maintenance. The tub holds 500 liters, providing enough space for two people. The stainless steel interior ensures the wood does not corrode, making the tub sturdy for repeated use. The ETL safety certification includes an anti-leakage setting that automatically cuts power if triggered, adding a layer of protection during operation.

Before You Buy This Tub

You need to check your electrical outlet before purchasing this unit. The chiller requires a standard home power source with anti-leakage protection. Ensure your ambient temperature stays between 32 and 113 degrees Fahrenheit to prevent the machine from jamming or freezing. You must drain the chiller’s internal water after each use to avoid cracking. The filter element needs regular cleaning and timely replacement to keep the water clean. You should also verify that your space can accommodate the 80-inch length and 33.5-inch width of the rectangular basin. This tub suits those who want a dedicated recovery station. It fits well alongside other hot tubs and spas if you plan to alternate between heating and cooling routines. The WiFi control lets you adjust temperatures remotely. Keep in mind that the wood exterior requires space for air circulation. You are buying a specialized immersion tool, not a general spa. Make sure you have room for the separate chiller unit with its wheels and handles.

Check before you buy

  • Verify outlet supports the chiller's power needs and grounding.
  • Ensure ambient room temperature stays above 32 degrees Fahrenheit.
  • Confirm you have space for the 80-inch tub length.
  • Check that you can drain the chiller after every use.
