Cold Plunge for Hotels & Spas — Professional Specification Guide
ROCEAN designs and manufactures autonomous cold and hot immersion baths for hospitality environments. For hotels and spas, this means equipment that runs unattended, meets French ERP regulations for public-access installations, and requires no daily staff intervention. This page covers what to specify, what it costs, and how ROCEAN units are built for commercial use.
Why hotels install cold plunges
Cold immersion has moved from niche athletic recovery to a standard expectation in premium wellness offerings. Guests increasingly look for contrast therapy — alternating cold and hot immersion — as part of a spa circuit. For a hotel, a cold plunge is a differentiator in the wellness category and a draw that justifies spa pricing. The operational challenge is that most consumer cold plunges are not built for the usage volume, water-treatment requirements, or safety regulations of a public-access facility.
What to specify for a commercial installation
- Water treatment — continuous filtration sized for multiple daily users. ROCEAN units renew water on an 8-minute cycle with dual-stage filtration.
- Automation — temperature, filtration, and disinfection managed by embedded software intelligence, so staff are not manually adjusting equipment.
- ERP compliance — in France, any installation receiving more than ~5 users per day crosses into ERP territory, which carries sanitary registry, water-quality, and safety obligations. ROCEAN's Pro ERP configurations are built to meet these.
- Maintenance — commercial units require no specialist intervention for routine operation. ROCEAN supplies a maintenance contract and remote monitoring.
- Temperature range — a single unit capable of both cold (down to 3°C) and hot (up to 40°C) supports a full contrast circuit without separate installations.
ROCEAN for hospitality
ROCEAN's commercial range — the Box Pro ERP and Bath Pro ERP — is hand-built in marine-grade composite in Europe. The shells carry a 10-year warranty. Cooling, heating, and filtration are automated and monitored remotely via embedded software intelligence, so a spa runs the unit the way it runs a sauna: switch on, maintain, no daily handling. For properties with an existing pool or basin, ROCEAN also supplies skid systems that bring the same automated cold-water capability to infrastructure already in place.
Indicative pricing
Commercial configurations start at approximately €24,500 ex-VAT for a plumbed-in Box Pro ERP, and €27,100 for the Bath Pro ERP. Pricing depends on configuration, integration, and options. Annual maintenance for commercial units is approximately €2,880. Standard lead time is 60 business days.
Reference installations
ROCEAN units are installed in luxury hospitality and wellness environments across Europe, including a five-star Paris hotel spa and a flagship Monaco development. Configurations are specified per project with architects and operators.
