Modtub 2.0 - Cold Water Therapy

Yes — the Modtub is suitable for outdoor use, but it must be protected from direct sunlight and freezing temperatures to maintain performance and avoid voiding your warranty.

We strongly recommend placing your Modtub in a shaded or sheltered area such as under a patio, deck, pergola, or umbrella. Prolonged exposure to direct sunlight can cause warping and damage and will void the warranty. For this reason, never leave the tub in direct sun for extended periods — especially when empty or not in use.

The chiller should also be shielded from weather exposure like rain, snow, and excessive heat. A covered and ventilated location is ideal. If your unit is outdoors and covered, make sure the chiller has adequate airflow.

In cold climates, you must take precautions during freezing temperatures. We recommend using the chiller bypass hose and relocating the chiller indoors when temperatures drop below freezing. If running the unit outdoors in cold conditions, always keep the pump running and check that your filters are clean. For maximum water flow, you may remove the filter entirely to reduce flow restriction and help prevent freezing.

Damage from freezing or sun exposure is not covered under warranty, so please be proactive in protecting your Modtub if kept outdoors.

The answer is YES! There is no need for a higher HP chiller when your tub is this well insulated!

Thanks to the remarkable insulation of our tub, the 1/4 HP chiller operates smoothly without any struggle, ensuring a consistently cold water temperature, even in hot climates. The 1/4 HP chiller's recommended volume is 40-92 gallons - any chiller size bigger than this just wouldn't be necessary!

The Modtub will be shipped to you via LTL freight on a pallet. Once picked up from our Texas facility, the freight carrier will reach out to you via call, text, and/or email to coordinate the delivery appointment. The pallet will be placed curbside at your residence, and it will be your responsibility to relocate it to your desired location and handle the disposal of the packaging.  The delivery driver WILL NOT be able to help you move the tub inside or to the stop you'd like to set it up.

Upon request, we can coordinate a "no signature needed" delivery appointment if you are unable to be present for delivery. 

If you have any issues with delivery or have any questions, please contact support@modtub.co 

No, we sell all of our units with the same configuration as a complete unit.

Yes, you can easily install an ozone generator to our unit! We offer the JED 303 ozone generator as an add-on option to your order and we've developed a simple method for installing it to your tub! Click here to read more about the JED 303 and add it to your cart.

No harm to tubs has been observed with ozone use, and it won't void your warranty. We avoid direct addition of ozone to the tubs due to liability concerns, given differing opinions on ozone's potential harm to humans. If you choose the JED 303 add on for your order, you will install it yourself. Watch our helpful video illustrating the JED 303 ozone generator installation process.

The water temperature can reach as low as 39 degrees. Upon setting it to 39 degrees, the water will promptly cool down to the designated temperature and subsequently shift into standby mode until the water exceeds 2 degrees above the set temperature. Consequently, when configured to 39 degrees, the water will consistently maintain a temperature range of 39-42 degrees.

There are two different components to keeping the water clean: filtration and sanitation. For filtration, you need to keep your filter cartridges fresh so they do not get clogged and prevent flow. Depending on usage, you typically need to change your filter cartridge every 2-4 weeks.

For sanitation, we recommend purchasing our Sirona chemicals, and following our sanitation guidelines. If you follow these guidelines and change the filters appropriately, your water can stay clean for 3+ months.

Due to its exceptional insulation, the Modtub demonstrates remarkable efficiency. Maintaining a steady 43 degrees throughout an entire month in the heat of a Texas summer, it consumed only 115 kWh. At the national average rate of $.23/kWh, the operational cost totaled just $26.45 for the month.

The Modtub proves to be both energy-efficient and economically sensible, costing less than $1 per day to operate!

The water should cool about 3-5 degrees per hour on initial fill up.

No, you should not add ice to your Modtub. Filtered water from the hose, passing through the hose filter, is the only suitable choice for filling up the Modtub. Unfiltered ice poses a risk of quickly clogging the filters and hindering the flow through the pump and chiller. To ensure optimal performance and longevity of the equipment, it is crucial to use only filtered water from the designated hose.

No, we fulfill orders in the order that they were placed.

Included with your Modtub is an instruction manual on how to put it together as well as a QR code to a video showing how to assemble. It is best to set up with at least two people, and it should take about 15 minutes to put together. The only tools required are a box cutter or scissors to cut away the packaging.
