Using a DIY Steam Shower Kit vs. Hiring a Shower Contractor

If you’re on a tight budget or you enjoy handiwork, a DIY steam shower kit is a great option. A prefabricated unit is $1,100 to $4,500 including a generator, fittings and steam heads. You will still need to hire a plumber and electrician in your area.

A hired contractor can manage the project for a total price of $2,650 to $6,050. This includes the unit, all materials and their time. We recommend this approach as it is stress-free compared to having to move a prefabricated unit into place yourself and sourcing a contractor team.
