Short answer: Yes, installing a steam shower is totally doable—but it takes planning, patience, and plumbing know-how. Whether you're dreaming of a spa at home or just love the idea of fogging up your mirrors like a pro, this guide breaks it all down. Keep reading to get steamy—the safe way.

Steam Shower Installation: Step-by-Step Guide
Before you begin, decide if you're going DIY or hiring a pro. Doing it yourself can save you money, but you’ll need to plan each step carefully. A professional handles it faster and ensures everything complies with UK regulations.
There’s no wrong choice—just the one that fits your skills and comfort zone.
Plan Your Space
Choose a fully enclosed area where steam won't escape. The walls and ceiling must be waterproof. Also, check that the space gives access to plumbing and electrics.
If your chosen room isn’t steam-tight, you’ll run into problems later. Fixing leaks after installation is much harder.
Select a Steam Generator
Your generator should match the size of your enclosure. Too small, and the steam won’t fill the space. Too large, and you'll waste energy.
Place the generator outside the shower area—an airing cupboard or utility room works well. Make sure it's easily accessible for servicing.
Prepare Plumbing and Electricals
The steam generator needs hot and cold water supply. It will also require a drain for the automatic flush function. A dedicated RCD-protected electrical circuit is a must for safety.
This is the point where you must bring in a certified plumber and electrician.
Build the Shower Enclosure
Use non-porous tiles like ceramic or porcelain so moisture doesn’t seep in. The ceiling should slope slightly to prevent condensation from dripping on your head. A sealed glass door helps trap the steam inside.
You want the space cosy, not cavernous.
Install Controls and Accessories

Fit a digital control panel where it’s easy to reach, either inside the enclosure or just outside. The steam outlet should sit near the floor, away from your body to prevent burns.
Optional extras include aromatherapy, LED lighting, and built-in speakers. It’s your spa—make it yours.
Test and Seal Everything
Seal all joints, edges, and tile gaps thoroughly. Run a full steam cycle and inspect for leaks or performance issues.
Don’t rush this step. It’s your final checkpoint before daily steam bath bliss.
