Luxury Ice Bath for Home Use: What Actually Matters
A luxury ice bath for home use is a plumbed cold plunge with an active chiller that holds a set temperature continuously, rather than a tub you fill with ice. At Medi-Spa, we specify and install these units for homeowners and athletes.
The difference between a good unit and a frustrating one comes down to three things: chiller specification, insulation quality and who installs it. Everything else is finish.
Cold water therapy works because cold exposure triggers a physiological response, and that response depends on consistency. A plunge that drifts from 8°C to 14°C between sessions is not the same protocol twice. That is the single argument for active chilling, and it is the argument most cheap tubs cannot answer.
Below, we break down the four Onyx models we install, what each costs, and how to work out which one fits your routine.
The Best Cold Plunge Tubs Compared
Here is how the four models compare on the factors that decide the purchase: price, chiller grade, dimensions and intended use.
| Model | Price | Chiller | Dimensions (L x W x H) | Best For |
|---|---|---|---|---|
| ONYX PLATINUMPRO | £9,999 | Highest specification in range | 220 x 211 x 82 cm | Commercial and heavy home use |
| ONYX Platinum | £7,499 | Higher grade, superior insulation | 212 x 102 x 81 cm | Daily structured protocol |
| ONYX GOLD | £5,499 | Active, stainless trim | 180 x 74 x 75 cm | Daily use, mid-range budget |
| Onyx Pulse | £4,499 | Active, 3-tier interior | Not listed | First active-chiller unit |
All four run on a 13A plug-and-play supply and include built-in filtration. Every model carries a 10-year structural warranty, 5-year acrylic warranty and 2-year chiller warranty.
ONYX PLATINUMPRO: The Commercial-Grade Flagship
The PLATINUMPRO is the top of the range at £9,999, and it is the only model in the line specified for commercial environments as well as homes. If more than two people will plunge daily, this is the correct unit.
It uses a full acrylic interior, which means hygienic surfaces that are simple to wipe down, plus the highest-specification active chiller in the Onyx range. Temperature control is digital and precise to a fraction of a degree.
Where it falls short: at 220 x 211 cm it is a substantial footprint, so it needs a properly planned siting rather than a spare corner. For a single daily user, you are paying for headroom you may never use.
ONYX Platinum: The Daily-Protocol Choice
Priced at £7,499, the Platinum is the model we recommend most often to homeowners who treat cold plunging as a routine rather than an occasional experiment. The higher-grade chiller cools faster and holds temperature better than the Gold, and the superior insulation means it does not have to work as hard to do it.
That insulation matters more than the spec sheet suggests. Better thermal efficiency means lower running costs over the years you own the unit, so the price gap narrows in practice.
The trade-off is straightforward: it costs £2,000 more than the Gold for performance you only notice if you plunge consistently. Buy it if you will. Skip it if you will not.
ONYX GOLD: The Mid-Range All-Rounder
At £5,499, the GOLD is the sensible middle. It carries the same core active chiller technology as the rest of the range, adds stainless steel trim for a sharper finish, and is built for daily use.
It is also the most compact of the three larger models at 180 x 74 x 75 cm, which makes it the easiest fit on a patio or in a garden room where space is tight.
What most buyers miss: the GOLD is the point where the range stops feeling like an entry product. If your budget tops out here, you are not making a compromise on the cooling itself.
Onyx Pulse: The Entry Point to Active Chilling
The Pulse starts at £4,499 and does the one thing that matters: it chills actively. You set a temperature and it holds it, regardless of ambient heat or how long you stay in.
Its 3-tier capacity design accommodates different heights comfortably, and built-in filtration keeps water clean between sessions without a full drain. For a first cold plunge, or for a household where one person plunges and the rest are curious, it covers the essentials.

The honest limitation is that the Pulse does not list external dimensions in the same detail as the larger models. It also lacks the upgraded chiller and insulation of the Platinum.
Why a Home Ice Bath with Chiller Beats Ice Alone
Ice cools water once. As you sit in it, your body heat raises the temperature, and the next session starts warmer than the last. An active chiller removes that heat continuously, so session ten is identical to session one. Maintaining this thermal consistency ensures that the physiological benefits of cold exposure are maximised, much like the restorative heat cycles provided by indoor infrared saunas.
The practical consequences are bigger than they sound:
- No ice runs, no freezer space, no last-minute trip to the shops
- No temperature drift mid-session as your body warms the water
- Built-in filtration keeps water clean between plunges
- The same protocol every time, which is the entire point of a protocol
A common mistake is buying a tub first and treating the chiller as an accessory. It is the reverse. The chiller determines whether the unit is a therapy tool or an expensive bucket.
Ice Bath Running Costs: What to Budget
Running costs for a home ice bath come down to three things: the chiller's efficiency, how well the tub is insulated, and the temperature you hold.
A well-insulated unit with a higher-grade chiller works less to maintain temperature, which is why the Platinum's superior insulation matters financially as well as practically. A poorly insulated tub loses cold continuously and the chiller runs constantly to compensate.
We do not quote a running figure here, because it depends on your set temperature, ambient conditions and tariff. What we will say is that insulation is the variable most buyers underestimate, and it is the one that decides your annual cost.
Ice Bath Installation Requirements
Installation requirements for an ice bath come down to access, siting and electrical supply. All Onyx models run on a standard 13A plug-and-play supply, which removes the need for a dedicated circuit in most cases.
Access is the factor that catches people out. A filled unit cannot be moved easily, so the delivery route needs to be confirmed before the installation date, not on the day. Our installation service is £499 and is booked separately after your order. We contact you beforehand to confirm access, siting and electrical requirements.
Installation prices exclude crane and lifting equipment, electrical work and any other specialist equipment or site preparation. Where those are needed, we quote separately.
If you are weighing up the total, budget for the unit plus installation, and treat any site preparation as a separate line. A compact patio is workable; the GOLD's 180 cm length is the most forgiving of the four.
Which Luxury Ice Bath Should You Pick?
The right luxury ice bath is the one whose chiller matches how often you will actually use it. Buy for the routine you will keep, not the one you imagine.
- Multiple users daily or a commercial setting: ONYX PLATINUMPRO at £9,999
- A structured daily protocol: ONYX Platinum at £7,499
- Daily use on a tighter budget or a compact space: ONYX GOLD at £5,499
- A first active-chiller plunge: Onyx Pulse at £4,499
If you are unsure, the Platinum is the safest recommendation for a committed home user, and the GOLD is the best value in the range. Both are backed by a 10-year structural warranty and installed by our own team.
Choosing a cold plunge is really a decision about consistency: whether the unit will still be holding the right temperature in year five, and whether anyone will still be there to fix it if it isn't. Medi-Spa is a family-run wellness specialist, and we deliver, install and support every Onyx unit ourselves rather than handing you off to a third party. Every model comes with a 10-year structural warranty, 5-year acrylic warranty and 2-year chiller warranty, plus optional servicing at £299 to keep it performing. Book a private consultation with Medi-Spa and we will confirm siting, access and the right model for your routine before you commit.
Frequently Asked Questions
How much does a luxury ice bath for home use cost?
In the ONYX range, the entry-level Onyx Pulse costs £4,499 and the flagship PLATINUMPRO costs £9,999. Installation is booked separately at £499, and prices include VAT. 0% finance is available subject to terms and conditions. Budget for a routine service at £299 to keep the chiller and water hygienic. Compared with filling a tub with ice daily, an active chiller removes the ongoing ice cost and prep time entirely.
Do luxury ice baths need plumbing or professional installation?
No plumbing is required. Every ONYX model runs on a 13A plug-and-play power supply. Professional installation is still recommended: Medi-Spa's own team confirms access, siting and electrical requirements before the visit. The £499 installation price excludes crane and lifting equipment, electrical work and site preparation, which are quoted separately if needed. A flat, level, load-bearing base and clearance on all sides make servicing straightforward.
Are home ice baths worth the investment?
The value comes from consistency. An active chiller holds your set temperature session after session, so a daily cold plunge protocol becomes practical rather than a chore. The PLATINUMPRO carries a 10-year structural, 5-year acrylic and 2-year chiller warranty, which spreads the cost over years of use. If you plunge occasionally, a cheaper setup may suit you; if cold therapy is part of your routine, a luxury ice bath earns its place.
How much space do I need for a home ice bath?
Sizes vary across the range. The Onyx Pulse and GOLD are the most compact at 180 x 74 x 75 cm, the Platinum measures 212 x 102 x 81 cm, and the PLATINUMPRO is the largest at 220 x 211 x 82 cm. Leave clearance on all sides for access and servicing, and check the delivery route before ordering. A remote assessment can confirm siting at no charge if you are further afield.
How do you maintain and clean a home ice bath?
Built-in filtration keeps water clean between sessions, but cold water systems can harbour bacteria and limescale if left unchecked. A professional Ice Bath Service costs £299 and covers a full drain and internal flush, sanitisation of the tub and pipework, filter check, chiller inspection, water refill and temperature calibration, plus a service report. It takes roughly one to two hours, and any replacement parts are quoted separately.
