When locating your spa indoors, follow National Electric Codes and all other local codes. Proper building materials should be used in the area surrounding and beneath the spa. Any water which splashes or leaks on the floor can cause a slipping hazard. Carpeting around a spa can be damaged by chemically treated water splashing on it. Providing forced air ventilation in the spa room will minimize moisture to the spa room. A ventilation fan will extract humidity and is recommended. Proper water drainage must be provided.
