Indoor spa setting with a steel cold plunge beside a glazed sauna cabin, warm floor light

Cold plunge, built into your space.

01 / 04

Acrylic or stainless basin.

Choose an acrylic shell in black or white for a built-in look, or a stainless basin where the finish is the feature. Interior lengths from about 196 to 204 cm, depth around 70 cm, one to two person capacity.

Start with the bath. Design the surround around how it’s used and serviced.

A good plunge installation looks like one considered object sitting in a room, and a technician can still get at the chiller a year later. Those two things fight each other if nobody plans for both. That’s most of what we do before the kit is quoted.

Three ways to order.

Integrated bath

Chiller lives inside the bath. One unit, one footprint, one power circuit. Best when the plunge sits in a room with no adjacent equipment zone.

  • Interior lengths 196 to 204 cm
  • 1.0 to 2.0 HP chiller, 110V or 240V
  • Acrylic shell: black or white
  • 1 to 2 person capacity

Separate bath + chiller

Bath in the wet room, chiller in an adjacent equipment or utility zone. Lets you plan ventilation for the chiller properly and keeps the plunge quieter underfoot.

  • Bath formats to match the room
  • Pair with any of the CW-CH chiller tiers
  • Chiller distance limited by refrigerant line length
  • Service access on both ends

Hot-cold pair

Sauna and plunge a few steps apart on the same build. We spec the two together so the deck levels, drains and electrical land as one project rather than two.

  • Coordinated with Crateworks indoor or outdoor sauna
  • Shared design-brief and installation guide
  • One quote, one lead time
  • See the sauna rough-in package

Chiller.

Three tiers of chiller across the lineup. All run on 110V or 240V single-phase. The electrician sizes the breaker from the chosen unit’s install manual; plan a dedicated circuit either way.

Compact

Capacity
1.0 HP
Power
~2.5 kW at 240V
Temp range
3 to 42 °C / 37 to 108 °F

The smallest bath format, or when the client just wants to hold temperature overnight.

Mid

Capacity
1.5 HP
Power
~4.0 kW at 240V
Temp range
0 to 42 °C / 32 to 108 °F

Standard choice. Pulls temperature down from room ambient in a few hours.

High-capacity

Capacity
2.0 HP
Power
~5.7 kW at 240V
Temp range
0 to 42 °C / 32 to 108 °F

Larger baths, faster recovery between sessions, or multi-user households.

Finish.

Three finish families across the lineup. Confirm the selected finish before ordering; combinations vary by model.

Black acrylic

Dark basin, dark trim. Reads like a feature object; shows the water surface sharply.

White acrylic

Light basin, calmer surface. Blends into a tiled wet room.

Stainless steel

On the separate-bath line. Industrial, cleans easily, pairs with concrete or stone surrounds.

Plan the space behind the finish.

A cohesive surround starts with the equipment layout and a clear maintenance route. Four things the architect or GC confirms before closing in.

Support & fit.

Confirm the exact model dimensions and loaded weight. Support the bath and the surrounding structure independently per the install guide. The rim does not carry a deck.

Airflow & heat rejection.

The chiller rejects heat. Confirm intake, exhaust and clearances before enclosing it. Universal clearances do not apply across models.

Water & servicing.

Plan accessible filters, unions, valves, drains and hose routes. Leave room for filter changes, leak inspection and chiller removal. Service panels have to be usable after finish.

Power & environment.

Confirm the voltage and the permitted installation environment. Have the install designed and connected by appropriate trades per the product instructions.

Reference installation. Final cladding, deck and surround detailed per project. We supply the bath and the chiller; your crew builds the surround to the install guide.

What we need from you to quote.

  • Room or location dimensions, including the equipment zone if separate.
  • Electrical panel location and available circuits.
  • Drain availability and floor height to it.
  • Finish lean (acrylic black / acrylic white / stainless).
  • If paired with a sauna, send both briefs together.

Common questions

Integrated when the room has no equipment zone next door and footprint is tight. Separate when there is a mechanical cupboard, utility room or adjacent service wall. Separate is quieter at the bath, easier to service, and lets you spec ventilation for the chiller properly.
All chillers run down to 0 to 3 °C (32 to 37 °F) depending on model. Pull-down from room temperature to 10 °C is a few hours on the 1.5 HP and 2.0 HP units, longer on the 1.0 HP. Once at temperature, the chiller cycles to hold it; the electrical draw drops substantially.
Both 110V and 240V options exist across the lineup. 240V is faster and quieter under load. The electrician sizes the circuit from the chosen model's spec; plan a dedicated circuit for the chiller, GFCI as code requires.
Any material that handles the moisture envelope and allows service access: timber cladding, tile return, stone deck. The non-negotiable is removable panels aligned with filters, valves, chiller controls and the chiller itself. A built-in bath with no service route is a repair bill waiting to happen.
Yes. We coordinate hot-cold pairs under one design brief and one lead time. See the sauna rough-in package for the paired install detail: same photo hold points, same shell kit model.
Plan on roughly 12 weeks door to door. Confirmed in writing at the quote. That is the delivered window including freight and customs, not production time alone.
