This is a photo of a whirlpool tub installed in the bathroom of a home I inspected in Castle Rock, Colorado. The tub is located in the master bath, is of good quality and is installed correctly. One of the most important safety features in a correct installation is to have the unit installed with its own separate GFCI (Ground Fault Circuit Interrupter) connection. This provides a safety shut-off of power in the event of an overload of current or problem with the wiring in the bathroom. The GFCI can be located in a wall outlet like this one, or under the vanity in the bath cabinets. It is essential that the tub unit have its own GFCI and not be part of the other GFCI installed for other outlets in the bath, as most electrical codes require this.
