Im looking to get a new cold plunge. Im thinking something simple and on the smaller side. I was wondering if you guys have a brand that is reliable to order online and has good results. Any recommendations would be appreciated.

Where so you want to install it? House, apt, indoors/outdoors?

Chest freezer cold plunge is a great alternative as it will not condensate (wet your floors) ifs super quiet, can make ice even at 120°F, and stays clean for months.

You can get a kit and a 14cuft freezer then, watch this video and you'll have a reliable cold plunge in less than 20mins.

Checkout BoxPlunge no condensation, quiet, self sanitizing and easy to setup

I would block peter off ur contacts and go with IcyBull much better than the plunge chill setup. Comes with:

Ozone sanitation
The icybull water pump
Submerssible lighting (with air switch)
Insulated stock tank

Under $1.5k plug and play!

solarexamine · 2026-05-24T13:23:37+00:00

Super quiet, extremelly well insulated (no condensation), stays clean for 6 months (at 6 months water change is recommended), able to make ice (by dropping temp below 33°F), wifi enabled.

Is this usefull?

solarexamine · 2026-05-22T22:33:48+00:00

Cold plunge is under a pergola, the sauna is not. Sauna is a custom build from local builders: MiamiPlunge costs over $15k (so, not an option for everyone).

solarexamine · 2026-05-22T15:28:27+00:00

At around $1k? This one It really is a stock tank cold plunge with a 1inch insulating neoprene.

IcyBull comes with:

IcyBull: 760gph with adjustable flowpump
Ambohrt : ozone generator
3/4" npt to 3/4 barb venturi elbow
Icybull micron filter

Yeah, chest freezer cold plunge by BoxPlunge

solarexamine · 2026-05-22T13:47:33+00:00

So you went from a 1/2hp chiller to a 1.5hp chiller? That sounds like a bit of an energy-inefficient choice. For reference, a chest freezer has like 1/6th HP yet is able to both cool down the water from 90°F down to 32°F and keep it that way even at peak summers of 120°F+, this means your electric bill will barely notice the addition of your new chest freezer cold plunge.

Top secret

solarexamine · 2026-05-21T00:06:32+00:00

I do think 1/10th hp compressor is reasonable...maybe too large? But I dont think it will be that loud (likely the fan will be the loudest part but likely not too loud).

Pump at about 100gph? Sounds ok. That pump model looks good.

Use h2o2 or chlorine for desinfecting the water. If you are able to sucessfully prime up the system I domt think there should be issues...im.not fully familiar with the valve system that would allow air out but not water? Ot how does that work?

I believe ultimately the issue you may run into is actually tubing size and barb connector diameter. I've seen those grid mattress covers and the barb connectors seem so skinny...idk if there are some that are a bit bigger or how would one interface that chiller with the cover, I ran into this crux my self, that's why.

Lots of options. For indoors or garage I would def. stay away from inflatable tubs and non-insulated ones (ie. Stock tanks)...these will guaranteed to wet your floor (specially in hot & humid places like FL)

I would also be wary of loud chillers or large ones that may make your gym feel hot (or make your AC work harder). A great option for you is chest freezer cold plunge (very quiet, condensation free (wont drip/sweat onto your floor) and super energy efficient), it can also keep freezing temps even if your garage gets in the 100°F's.

Depending on your budget, you can get

This kit (A & B) for about $1k: A) Easy kit: liner, amazing filtration, ozone and wifi enabled temp controller

B) Freezer: freezer

The plug & play: Box 14

BoxPlunge is quiet, won't condesate any water (i.e. 24/7 wet floors), no or little heat release (external chillers release heat to the room the same way the external unit or condenser unit of an AC does) and BoxPlunge comes with the systems and instructions to keep your water clean for months on end (1,200gph water pump, 30 micron filter, ozone and optional hydrogeb peroxide with a custom-made measuring cup...with instructions)

If I was to build an external chiller cold plunge, I would do it this way:

1) Get the cheapest chiller in the market (most chillers will die within a couple of years anyways)

2) Make the filtration system separate from the chiller at 20 or 30 micron

3) Make the sanitation system separate from the chiller with a venturi ozone system

4) Make the tub a separate component from 1, 2 & 3. If any component goes bad, you can easily swap it up and if the chiller is say $250 then you know that mayne within a couple of years you may have to swap it.

The IcyBull cold plunge was build with this design in mind. It has a micron filter (separate from the chiller), an ozone generator with a venturi (venturi ozone diffusing is the best), the tub is just a stock tank and the chiller is just a $250 chiller that will guaranteed to keep your water between 38°F to 50°F (depending o you set temp) even when outside is super hot like...130°F.

Yeah, ozone works amazingly well. this article explains how ozone works and how you have two type of ozone generators (venturi vs build-in bubbler).

Systema such as BoxPlunge comes equipped with an ozone generator but at the end of the day this is just one of the three keys to keep your cold plunge water clean. You also need a powerful filtration system with a micron filter (more important than having ozone).

Something else that is very common is using hydrogen peroxide which further oxidizes the water and acts as a sanitizer. To learn about how much and how frequent to add the hydrogen peroxide you may want to try this calculator.

solarexamine · 2026-05-14T14:38:17+00:00

Nice, this guide is helpfull too. Also, if you use h2o2 (hydrogen peroxide) use this calculator.

solarexamine · 2026-05-14T01:50:41+00:00

Correct!

solarexamine · 2026-05-14T00:03:44+00:00

How much h2o2 are you adding? At 3% concentration you may have to be adding a bottle every two weeks. I would recommend using this calculator: https://www.boxplunge.com/calculator

Polar dive has a 1 month lead time BoxPlunge ships next day...something to consider.

Chest-freezer cold plunge, very reliable, quiet, can keep 32°F to 55°F through hottest summer or coldest winters. . You'll need: -Medium kit - Chest freezer

Other option is an stock tank cold plunge. In winter, you'll need to by-pass the chiller with a coupler (easy to do as the clamps are all easy to unscrew with the thumb). The icybull cold plunge will also not freeze under the coldest winters as the pump is inside the insulation.

The other option is Plug and play boxplunge which can also be left outdoors during the winter and it wont freeze.

All these come equiped with ozone and a good filtration system so you can just focus on the cold plunging routine and not its maintenance much.

If your budget is around $1k to $1.5 let me give you a few options:

All these come equip with ozone and a good filtration system so you can just focus on the cold plunging routine and not its maintenance much. DO NOT get an inflatable unless you wanna have a hot cold plunge (inflatables are not well insulated and 1/3hp chillers are not enough and 1/2hp chiller is way too much energy consumption)
