Steam Shower and Sauna on same breaker?!

[Verdecken]

I was asked a question I feel like I knew the answer to, but after reading through 680.40 and associated sections I can’t see anything against what I’ve been asked to do.

A customer had a steam shower installed by another company which has a 220v dedicated 30 amp breaker. He wants to now add, in the corner of his bedroom, an infrared sauna. The sauna is also 220v, this time asking for a 15amp breaker. He would like to pull power from the same junction box as his steam shower to power it, claiming he’ll never be using both at the same time anyways.

While it is sound enough to have a junction with a 15amp gfci breaker ran from the same 30 amp breaker as the steam shower, and even if he did turn them both on, the breakers would quickly stop any potential damage, I feel like it’s not allowed.

Is there any codes saying I shouldn’t do what he is asking?

If the manufacture requires a dedicated circuit for either of these then it would be a code violation. 110.(3)(b). Not a good ideal regardless! You are going to own the installation. If he starts using both at the same time and the breaker trips…..who is he going to call? Not being critical ….but most people will make suggestions to save themselves money. Do it the way it should be with a dedicated circuit for each and put the money in your pocket, not his!

Thanks for the code, while the sauna is not asking for a dedicated circuit, the steam equipment does. Solved my dilemma in one fell swoop. Thanks for the help.
