Cost to Install a Steam Shower
Installing a steam shower combines a shower tray, steam generator, water and drain connections, electrical components, controls, and a sealed enclosure. It is a hard project because the enclosure must be vapor-tight, the generator must suit the shower volume, and the electrical and plumbing connections require professional installation.
Common reasons homeowners do this job
- Upgrading a bathroom to add steam bathing.
- Building or remodeling a bathroom with a dedicated steam shower.
- Replacing worn or damaged shower components during an upgrade.
- Changing a shower layout to include space for a seat, steam head, and control panel.
DIY or call a pro?
A licensed professional should handle the high-voltage electrical work and plumbing connections. Improper sealing can allow mold growth and structural water damage, so the enclosure needs careful vapor-tight sealing and leak testing. Check with your local building department whether this work needs a permit.
Frequently asked questions
- Can I install a steam shower myself or should I hire someone?
- This job calls for a licensed professional for the electrical and plumbing connections because the installation includes high-voltage electrical work. Professional installation also helps ensure that every joint and surface is sealed to prevent mold growth and structural water damage.
- What makes a steam shower installation more expensive?
- The price can rise with the job size, labor time, and materials such as the steam generator, thermostatic valve, plumbing connectors, wiring, backer board, and sealant. Removing old material can add haul-away or disposal work, and a small installation may include a minimum or trip charge.
- What should be checked before choosing a steam shower generator?
- Confirm that the space has dedicated water supply lines, a proper drain, and a dedicated electrical circuit. The generator should be compatible with the shower volume, and the layout should leave room for a seat as well as the steam head and control panel.
- Where does the steam head go in a steam shower?
- Install the steam head 6 to 12 inches from the shower floor. Its placement should be planned with the control panel and thermostatic valve before the enclosure is sealed, since all joints and surfaces must become vapor-tight.
