All water fittings in a bathroom must be supplied via an appropriate and adequate form of backflow protection, one which is rated either equal to or higher than the highest downstream contamination risk (fluid category) for the type of backflow (back pressure or back siphonage) it is likely to be exposed to.
The backflow risks associated with a spa bath will vary dependent upon its design, use (intended or otherwise) and the environment in which it is sited. As they are potentially a fluid category 5 risk the local water undertaker should be contacted prior to installation.
