The Plunge Supplier GD-SS01 Stainless Steel Cold Plunge Tub with Chiller: a lie down tub in two lengths
The Plunge Supplier GD-SS01 Stainless Steel Cold Plunge Tub with Chiller is a one person kit for indoor or sheltered outdoor use. Step over the side and lie back for a cold soak. Choose 59 by 29.5 by 24 inches or 67 by 30 by 24 inches. Both hold 105 gallons. The steel wipes clean easily. 304 is the standard stainless grade; 316 costs more and stands up better to salt air and pool chemicals. It runs on a standard 120 volt household outlet, so no electrician is needed.
The chiller is a separate box that sits beside the tub and connects with the hoses in the kit. The included 1 horsepower chiller heats and cools from 38 to 108 degrees Fahrenheit. A paper filter catches debris, while ozone disinfects the water to reduce chemical use. You get color changing underwater lighting and temperature controls on the unit or phone app. Covers, hose connectors, seals, two filter cartridges, and a filter wrench are included. Keep the covers on between soaks to hold the temperature. Pick your size, then steel grade; a Promax chiller upgrade is optional. Need less floor space? See the Plunge Supplier GD-SS02 Stainless Steel Cold Plunge Barrel with Chiller. The Plunge Supplier GD-SS01 Stainless Steel Cold Plunge Tub with Chiller ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

Stainless Steel Guide
304 vs. 316 Stainless Steel — What’s the Difference?
Both 304 and 316 are high-quality stainless steels known for durability, corrosion resistance, and strength. The main difference comes down to one added element:
316 Stainless Steel
316 has 2–3% molybdenum, which dramatically boosts corrosion resistance — especially against:
- Saltwater
- Chlorides
- Harsh outdoor environments
- Chemicals
- 316 is more expensive (usually 15–30% more) because of its enhanced composition
304 Stainless Steel
304 Stainless Steel does not contain molybdenum
- Great for indoor and general outdoor use
- Can show pitting or corrosion over time near the ocean or when exposed to salts/chlorine
- 304 is more budget-friendly while still offering excellent durability
Common Uses
316 Stainless Steel
-
Marine equipment
-
Cold plunge tubs exposed to chlorine or salt
-
Coastal installations
-
Medical and surgical equipment
-
Chemical environments
304 Stainless Steel
-
Appliances
-
Indoor tubs and tanks
-
Furniture
-
Mild outdoor environments
-
Food-grade equipment
FAQ about Molybdenum
- Molybdenum is a naturally occurring trace mineral found in soil, plants, and even the human body.
- It’s essential for human health in small amounts because it helps enzymes function properly.
- In stainless steel, the molybdenum is tightly bound within the metal alloy and does not leach out in any meaningful way.
So when used in 316 stainless steel, molybdenum is:
-
Not toxic
-
Not harmful to humans
-
Not a health concern, even with daily contact (e.g., water bottles, cookware, cold plunge tubs, medical tools)

FAQ
Should I choose 304 or 316 stainless steel for the tub?
The Stainless Steel Guide tab on this page explains it: 304 is the standard grade and suits indoor and mild outdoor use, while 316 adds 2-3 percent molybdenum for much better resistance to salt, chlorine and coastal air. Pick a size first, then the 316 upgrade appears on the selector with its price shown.
What sizes does the GD-SS01 come in?
Two: a 59-inch tub at about 59 x 29.5 x 24 inches and a 67-inch tub at about 67 x 30 x 24 inches, both rated at roughly 105 gallons. Choose on the Size selector; the stainless-grade option that follows is matched to the size you picked. The linked spec sheet notes the vendor can also customise sizes.
Is a chiller included with the stainless tub?
Yes. The IA-10HC 1 HP chiller with heating and cooling comes in the box together with hoses, connectors and seals, two filter cartridges, a filter wrench and thermal covers. The Promax chiller upgrade is offered on the page if you want more capacity. Other steel and acrylic options are in the cold plunge tub collection.
Is the molybdenum in 316 stainless safe to bathe in?
Yes. The Stainless Steel Guide tab addresses this directly: molybdenum is a naturally occurring trace mineral, it is tightly bound within the alloy and does not leach out in any meaningful way, so daily skin contact is not a health concern. It is the same reason 316 is used for medical tools and cookware.
What temperature range does the chiller give?
The Specifications tab lists 38 F minimum and 108 F maximum, handled by the dual-function 1 HP chiller, so the tub works for cold plunges and for warm contrast soaks. Stainless conducts heat well, so keeping the thermal covers on between sessions makes a noticeable difference to how long the water holds its temperature.
How do I clean a stainless steel cold plunge?
The description highlights that stainless is corrosion resistant, hygienic and easy to clean. Wipe the interior with a soft cloth and a mild non-abrasive cleaner, rinse and dry, and avoid steel wool or chlorine-based products that can mark the surface. The chiller’s 20-micron filter and ozone system handle day-to-day water quality.
How heavy is it when filled?
The Specifications tab lists about 400 lb empty and roughly 1,275 lb filled with its 105 gallons of water, not counting the chiller beside it. That is fine on a slab or rated deck; for a balcony or upper floor have the load checked first. The Features tab suggests a sheltered spot for the 304 grade for longer life.

What Our Customers Say
D
A sauna turns your garden into a spa oasis. We debated it for a while, but after renovating our house, we pulled the trigger and bought a sauna from Norse Steam and Maya. She was always super responsive and helpful throughout the process. Don't kid yourself, getting a really nice sauna is not that easy. Sizing and heating need to be figured out, as does the building, but we have always had a helpful partner on our side. She never upsold us on anything we didn't need, and we got some nice freebies when the sauna was delivered. And now we can really enjoy every moment in our garden.
KF
I'm really happy with my sauna purchase. Maya gave above and beyond excellent customer service. She wasn't pushy and gave impressive followup after the delivery to make sure everything was just right.
DE
I enjoy my FD2 Sauna with Red Light, Infrared and radiant heat. Use it 5x a week and my post workout soreness is minimal and sleep great. Maya at Norse Steam was excellent to work with.
B
We purchased the 3-person sauna for our outdoor garden. We chose the cube sauna for the aesthetic and could not be happier.
I assembled by myself except for the 2 large panels (requires a few people). Instructions were good - took me two partial Saturdays to complete and a few hours to unpack and organize in advance of assembly. Had my elec. add a NEMA enclosure on the back for the controller and power for lights and a 2nd panel for the wireless control.
Customer service was excellent

Awesome Sauna and Awesome Company and Experience purchasing it from Maya!
After much research I chose the Finnmark FD-2 and it has met and exceeded all my expectations! Easy to assemble and it functions great - just as advertised. I highly recommend it for home use!
EA
Recently purchased the Finnmark one person after much research. Extremely happy with it and the ordering process. Maya was very responsive and helpful during the process and keeping us updated while we waited for shipment. There were several places I could have ordered this, but i chose Norse Steam based on the communication and customer service which was fantastic. The shipment was also excellent. The setup was pretty seamless for two people - but the best part is the sauna experience 10/10
G
Maya is amazing - super helpful and responsive. Looked at many stores, these guys have the best prices and service. Highly recommend
GR
Norse Steam, and specifically Maya, were extremely helpful as I was making the decision for our Sauna. I was able to get all of the necessary details to make a decision as construction was happening in my backyard to make space for it.
We absolutely love the CL7G. It is extremely comfortable for 6 people (can fit more less comfortably). The Thermory Spruce and Aspen in the interior smells great. The lighting is lovely. We paired the CL7G with the Harvia Spirit 10.5kw.
RS
Had great experience shopping at Norse Steam for the new heater. They had very good deal, with rocks. Customer service was good, and responded very fast with my questions. Received the heater, and it looks good, and the quality seem to be great. Will install soon, and am very excited to start experiencing sauna the way it ment to be

Smoking Hot Tub!
I got the Norse Steam SaunaLife wood-fired hot tub, the S4N model, and its been seriously great. It heats up quicker than I expected, usually around an hour and a half, and once its hot, it stays that way for a good long while. The wood-fired system is simple to use, and honestly kind of fun.
The tub itself feels solid and well put together. The thermo-spruce exterior looks beautiful in person, and the fiberglass interior is smooth, deep, and easy to clean. Its the kind of setup that just works without a bunch of fuss, which I really appreciate.
Also, the team at Norse Steam was genuinely great to work with. Super helpful, quick to respond, and made the process really easy from start to finish. It felt like they actually cared that I was happy with it. The tub has totally become a go-to way to unwind, and I wouldnt change a thing.

Great Sauna & Purchase Experience
Great experience purchasing Finnmark FD-2 from Norse Steam. Good communication and easy to assemble. Temperature increases quickly (30 minutes or less to 140) and maintains well. So far this has been a great purchase.
M
Great sauna and great customer service
We purchased the Finnmark SD-1 sauna. Maya was extremely helpful with the purchase. We had an issue with the sauna not reaching the maximum temperature, and Maya connected us with the appropriate technician that explained how to correct the issue. The sauna now heats to the maximum temperature (170 degrees) in less than an hour, and it is a great unit. We are very happy with it, and we would definitely purchase from NorseSteam if we needed any other items.

Sauna Review
I recently purchased a sauna from Norse Steam, and I couldn't be more impressed with the entire experience. From start to finish, their customer service was exceptional, and Maya deserves special recognition for her outstanding support!
Maya was incredibly knowledgeable and patient, answering all my questions about the sauna features, installation process, and maintenance. She went above and beyond to ensure I selected the perfect model for my home. Even after the purchase, Maya followed up to make sure everything was running smoothly and that I was satisfied with my sauna.
The sauna itself is top-notch beautifully designed, durable, and easy to use. It's clear that Norse Steam takes pride in the quality of their products and their commitment to customer satisfaction.
If you're considering a sauna, I wholeheartedly recommend Norse Steam. With their excellent customer service and high-quality products, you're in great hands. Thank you, Maya, and the entire Norse Steam team for a fantastic experience!
