Way out west, customs are a little different when it comes to spas. We realize that variable levels of underwater “mood lighting” and invigorating jet-pump streams are an integral part of the total spa experience.
Not shown is the important bamboo-handled loofa brush that serves double duty. Besides ritual exfoliation, the natural organically insulated brush handle also serves to safety operate the spa-side circuit breakers for the lighting and pumps—so very essential to truly effective relaxation during a dip.

Loofa aside, an advance in 1990 was Hughes Aircraft’s "Clapper II+" pump and lighting control.
The Jet Propulsion Laboratory is currenty in development of a NEMA-4X chlorine-submersible TiVo/spa remote control, made entirely from recycled polyethylene terephthalate Evian-Water bottles.
David, You're quite right there. Over in NZ, you are not even allowed to install a switchboard in the same wall as a bathroom, even, if the b/room is on the other side of the wall!. Or above a stove. Never seen anything this bad before!.
Once again, I'd like to point out that there is NO NEMA enclosure that is tested for resisting condensation. Those who deal with panels in industrial locations that are subject to condensation have a variety of methods to reduce their very active maintenance requirements!
