Shipping & Delivery
Shipping & Delivery
Your order ships free from the manufacturer's California warehouse on a strapped pallet via insured LTL freight. Orders are processed within 2 business days, and delivery to most addresses in the contiguous US takes 5–7 business days after shipment. You'll receive a tracking number by email as soon as your order leaves the warehouse.
Scheduling your delivery. The freight carrier will reach out before the truck rolls — most carriers call 24–48 hours ahead to lock in a four-hour delivery window. Some carriers (including R+L) send an email or text the morning of delivery instead. Respond promptly either way. If the carrier can't reach you and misses 2–3 delivery attempts, terminal storage fees kick in and the item may be returned at your expense.
What to expect at delivery. A 53-foot semi-truck arrives at your curbside. The driver uses the truck's built-in liftgate to lower the pallet to ground level — that's where their responsibility ends. Standard delivery does not include bringing the equipment inside, up stairs, or unpacking. Plan ahead: have help available to move it once it's off the truck. Someone must be present to sign for the delivery.
CRITICAL — inspect before you sign. Walk around the pallet and check every box before signing the Bill of Lading. Note any scratches, dents, or scuff marks directly on the delivery receipt. If you see a large hole, crushed corner, or obvious structural damage, refuse the delivery — we'll ship a replacement at no cost. Signing a clean BOL releases the freight carrier from all liability. A damage claim cannot be filed after a clean signature. This takes two minutes and fully protects you.
Good to know. If your address changes after the order ships, contact us immediately — carrier re-routing fees may apply and will add transit time. If your location cannot comfortably accommodate a 53-foot semi-truck (island, remote road, gated community, narrow access), contact us before ordering so we can arrange an appropriate solution.
Free freight applies to standard residential curbside delivery within the contiguous 48 US states. Hawaii, Alaska, and Canada are not available at standard checkout — contact us before ordering for a freight quote. Transit times are carrier estimates, not guarantees. Applies to all Golden Designs Inc. brands: Dynamic Saunas, Maxxus Saunas, and Dynamic Cold Therapy. View our full Shipping & Delivery policy →
Return Policy
Return Policy
We stand behind every product we sell. If it's not the right fit, you have 30 days from delivery to return it — and if you need to cancel before it ships, you can do that within 24 hours of purchase at no charge.
How to start a return. Email us your order number at sales@recoveryroomdirect.com and we'll issue a Return Merchandise Authorization (RMA) number within one business day. Write that number clearly on the outside of every box before handing it to the carrier — the warehouse will not accept returns without it.
Condition required. The item must come back new, unused, and in its original packaging with all components, hardware, and accessories included. Items that have been assembled, used, or modified cannot be returned. Electronic components — power supplies, control panels, and accessories — are non-returnable under manufacturer policy regardless of condition.
What it costs to return. We want to be upfront about this: returning large freight equipment has real costs. The manufacturer charges a 20% restocking fee on all returns, and you are responsible for the return freight. If your original order shipped free, the actual outbound freight cost is also deducted from your refund. Any storage or carrier routing fees incurred during the return process are the buyer's responsibility as well. Once the item arrives at the warehouse and passes inspection, your refund is issued within 5 business days to your original payment method.
Damaged on arrival? That's a different process entirely — and you're fully protected. If you refused the delivery and documented the damage on the Bill of Lading, we handle the freight claim and ship you a replacement at no cost. No restocking fee, no return shipping. This is exactly why we ask you to inspect carefully before you sign.
The manufacturer warranty covers defects that arise after the 30-day return window. See full warranty terms at goldendesigninc.com. Questions about your order? Call us at 1-888-500-5675 or email sales@recoveryroomdirect.com — Mon–Sat, 9am–6pm EST. Applies to all Golden Designs Inc. brands: Dynamic Saunas, Maxxus Saunas, and Dynamic Cold Therapy.

PRODUCT DESCRIPTION
The 304 Stainless Steel Cold Plunge Tub That Fits Most Buyers Perfectly
For buyers up to 5’8”, this is the right tub. Same 304 nano-coated stainless steel as the XL. Same Pacific Cedar trim. Same chiller-ready 3/4" ports. At $5,499, the Cuboid Standard delivers the full 304 stainless steel cold plunge experience without paying for five inches of interior length you may not need.
Shop Pay installments, powered by Affirm, available at checkout — spread the investment over time. Free freight delivery included.
The Right Tub for Most Buyers — Not a Compromise
At $5,499, the Cuboid Standard is $500 less than the XL and built from identical materials. We want to be direct with you: the only difference between these two tubs is five inches of interior length. That’s it.
If you’re 5’8” or shorter, the 43.5” interior of the Standard covers you from shoulder to foot without your knees having to bend above the waterline. For the majority of buyers, the Standard is not a step down from the XL — it is the correct size for their frame. Spending $500 more for length you don’t use does not make the cold therapy more effective.
If you’re taller than 5’8” and want your legs fully extended during immersion, the Cuboid XL at $5,999 is worth the extra investment. For everyone else, this is the tub we’d recommend.
304 Nano-Coated Stainless Steel — Where Premium Cold Plunge Starts
The interior and exterior of the Cuboid Standard are both 304-grade stainless steel with a nano-coating engineered to outlast the alternatives. This is the same material decision that separates a cold plunge you replace in three years from one you keep for a decade.
A passive chromium oxide barrier forms at the surface, protecting against corrosion, mineral staining, and oxidation from cold or chlorinated water. No liner to degrade. No plastic to crack under daily use. The same alloy used in commercial food processing for its non-reactive, non-porous properties.
Pacific Cedar is naturally antimicrobial, dimensionally stable in wet environments, and resistant to decay without treatment. It adds structural rigidity to the stainless cabinet and ages gracefully whether placed indoors or outdoors year-round.
Standard 3/4” IN/OUT fittings connect directly to both DCT 0.8HP and 1.0HP WiFi chiller units with no adapters required. The tub also supports ice-over-water sessions — gravity fill and manual drain work without a chiller.
Included at $5,499 — No Follow-Up Purchases Required
The Cuboid Standard ships as a complete, ready-to-use cold therapy system. Everything you need for day-one immersion is in the box.
4” Insulated Cover (Included)
The custom insulated cover with child safety latches maintains water temperature between sessions and prevents unsupervised access. If you’re running a chiller, a well-insulated cover significantly reduces the energy needed to hold your target temperature. A replacement cover is available separately in our store.
Compatible with the DCT Chiller Ecosystem
The 0.8HP WiFi Chiller provides consistent automated temperature control for residential daily use. The 1.0HP handles higher-volume applications. Both connect directly to the 3/4” ports. Chillers are sold separately — add one at checkout or call (888) 500-5675 and we’ll help you choose the right unit for your protocol.
Pacific Cedar Step Stool (Included)
Entry and exit from a cold plunge tub are often underestimated in terms of safety. The included Pacific Cedar step provides the correct ergonomic height for a repeatable, controlled mounting motion — particularly important on the way out when the body’s thermoregulatory response is most active.
How Consistent Practitioners Structure Their Cold Sessions
Cold immersion works through repetition, not intensity. The Cuboid Standard is designed to be used daily, not occasionally. Here’s how to build that habit.
A 2–4 minute immersion before caffeine. Research on cold water immersion suggests it may support norepinephrine and cortisol awakening responses — helping to establish mental clarity before the demands of the day. Many practitioners report this replaces their first coffee within a few weeks of daily use.
Target: 50–55°F. Duration: 2–4 min. The discomfort at entry is the mechanism. Breathe slowly through it.
The 43.5” interior provides full immersion for buyers up to 5’8” — covering the lower extremities where micro-tears, systemic inflammation, and neural fatigue accumulate after training. Research suggests cold immersion may help modulate the acute inflammatory response and support recovery between sessions.
Target: 45–55°F. Duration: 10–15 min. If hypertrophy is the goal, wait 30–60 min post-lift before plunging.
A 5–7 minute immersion 90 minutes before sleep accelerates the core body temperature drop that typically precedes deep sleep onset. Research on thermoregulation and sleep architecture suggests this may support sleep quality and time-to-sleep without disrupting circadian rhythm.
Target: 55–60°F. Slightly warmer for sleep priming — you’re winding the nervous system down, not training it.
Who the Cuboid Standard Is Built For
The Standard is the right choice for the majority of cold therapy practitioners — and for most buyers, the smarter investment.
You’re not experimenting with cold exposure — you’ve decided it’s part of your daily stack. You want a stainless steel tub that can be sanitized properly, holds temperature when connected to a chiller, and doesn’t need to be refilled from scratch each session. At 5’8” or under, the Standard gives you full immersion and saves the $500 the XL would cost you for length you don’t need.
You’ve researched the catecholamine response and cold-shock protein activation. You know temperature and duration are the variables that drive outcomes — not whether your interior is 43.5” or 48.5” long. You want 304 stainless steel because it’s non-reactive and can be kept hygienically clean. A DCT WiFi chiller on the 3/4” ports gives you programmable temperature precision. This is the right setup.
For commercial applications where client height profiles are mixed and the priority is consistent protocol delivery and sanitation, the Cuboid Standard covers the majority of clients effectively. The 304-grade stainless interior supports hospital-grade cleaning protocols across high-use days. For commercial volume pricing or multi-unit orders, call us at (888) 500-5675.
The Math on Owning vs. Going Out
Cold therapy spas and cryotherapy clinics charge $50–$80 per session. Here’s what the Cuboid Standard costs per use at daily frequency.
HSA and FSA funds may be applicable to wellness equipment — check with your plan provider before purchase. Shop Pay installments, powered by Affirm, are available at checkout to spread the $5,499 investment over time.

Shipping & Delivery
The Cuboid Standard ships via freight carrier with free curbside delivery included. Estimated transit: 5–10 business days after dispatch. You will receive tracking by email when your order ships. Curbside delivery means the carrier brings the pallet to your curb or driveway — not inside the home.
Threshold delivery, inside placement, or full room-of-choice setup is available as a paid White Glove upgrade. Plan your placement route before delivery day — the filled tub weighs approximately 1,350 lbs. To discuss White Glove options, call (888) 500-5675.
Filled weight is approximately 1,350 lbs (~140 gallons). Concrete slabs, reinforced patios, and ground-level floors handle this load without issue. Elevated decks or upper-story placement should be confirmed with a contractor before ordering. Call (888) 500-5675 to discuss your setup.
Arrives fully assembled. Chiller connections use standard 3/4” hose fittings — no specialist required. Fill with a garden hose. Drain via the 3/4” OUT port into an appropriate outdoor area or floor drain.
DCT Cuboid Standard — Frequently Asked Questions
What is the difference between the Cuboid Standard and the Cuboid XL?
Both models use identical materials: 304 nano-coated stainless steel interior and exterior, Pacific Cedar trim, 3/4” chiller ports, an insulated cover with child safety latches, and a cedar step stool. The only difference is size. The Standard has a 50” exterior (43.5” interior); the XL has a 55” exterior (48.5” interior) — five additional interior inches. For buyers 5’8” and under, the Standard provides full immersion coverage at $500 less. For taller buyers who need full-leg clearance, the XL is the right call.
Do I need a chiller, or can I use ice?
You can use either. The 3/4” ports support chiller connectivity, but the tub also works with ice-over-water sessions — fill with cold water, add ice to reach your target temperature. A chiller provides automated, consistent temperature control without daily ice management. The DCT 0.8HP WiFi Chiller handles most residential cold therapy protocols. The 1.0HP handles higher-volume commercial use. Both are sold separately — add one at checkout or call (888) 500-5675 for a recommendation.
What temperature can the Cuboid Standard reach?
The tub does not generate temperature on its own — temperature is controlled by the chiller you connect to it. The DCT 0.8HP and 1.0HP WiFi chillers cool water into cold therapy ranges appropriate for immersion protocols (see each chiller’s specification sheet for exact minimums). With ice alone, temperature depends on ambient conditions and ice quantity. For precise and consistent temperature control session to session, a DCT WiFi chiller is the practical solution.
Is the Cuboid Standard suitable for outdoor use year-round?
Yes. The 304 nano-coated stainless exterior and Pacific Cedar trim are both designed for outdoor durability. In climates where temperatures drop below 32°F, drain the tub if the chiller isn’t running — water left standing in the lines can freeze and cause damage. Contact us at (888) 500-5675 for winterization guidance based on your region.
Is the insulated cover included, or purchased separately?
The 4” insulated cover with child safety latches ships with the Cuboid Standard — it is included at no additional cost. The separately listed cover in our store is a replacement unit for buyers who need a spare or want to replace one after extended use. You do not need to purchase an additional cover when ordering the Standard.
What surface can the Cuboid Standard be placed on?
Filled weight is approximately 1,350 lbs (~140 gallons of water). Concrete slabs, reinforced patios, and ground-level floors handle this without issue. Elevated wood decks should be inspected by a contractor before you place the tub — the filled weight may exceed the deck’s designed load rating. Upper-story placement requires a structural assessment. Call us at (888) 500-5675 to walk through your specific setup.
Can the Cuboid Standard be used alongside a medical or physical therapy program?
The Cuboid Standard is a wellness device, not a medical device. It is not intended to diagnose, treat, cure, or prevent any medical condition. Many buyers use it to complement — not replace — clinical care during recovery phases. If you are under the care of a physician or physical therapist, discuss how cold water immersion fits into your protocol before use. Certain cardiovascular conditions, Raynaud’s syndrome, and open wounds contraindicate cold immersion — consult a qualified healthcare professional before beginning any cold therapy protocol.
Is Shop Pay financing available for the Cuboid Standard?
Yes. Shop Pay installments, powered by Affirm, are available at checkout — allowing you to split the $5,499 purchase into manageable payments. Terms and approval are determined at checkout. HSA and FSA funds may also be applicable to wellness equipment — check with your plan provider before purchase.
