Steam Showers UK: How to Choose
A steam shower replaces a standard shower cubicle with a sealed unit that generates pressurised steam at the press of a button — alongside a regular shower, hydromassage jets, chromotherapy lighting, and integrated audio. Done well, it’s a daily spa experience that doesn’t require a wet room renovation.

Quick answer: which steam shower is right for you?
- Compact bathroom, replacing a shower → Single-person quadrant or square (800×800 to 1000×1000mm).
- Larger bathroom, single user, full spec → 1200×900mm rectangular with hydromassage, chromotherapy, audio.
- Couples or family bathroom → 1400×900mm twin cabin with dual showerheads.
- Replacing both bath and shower → Steam shower bath combination (1500×850mm).
Self-contained vs custom-built
Self-contained steam showers
A self-contained unit is a pre-fabricated cubicle delivered as a kit — walls, tray, ceiling, steam generator, controls, and plumbing connections all designed to work together. Connect to hot and cold mains and a drain, plug in the electrics, and it’s ready. Most home installs: 1–2 days. Browse our full range.
Custom steam rooms
A custom steam room uses a separate generator behind the wall with a fully tiled cubicle. Premium aesthetic but 3–5x the cost, weeks of installation, and requires specialist tradespeople. Not covered in this guide.
What to look for
- Steam generator output: 2.6–3.0 kW for a single-person cabin; 3.5–4.5 kW+ for larger units.
- Glass thickness: 6mm minimum, 8mm preferred.
- Showerhead spec: Look for a large rain head (200mm+), handheld, and body jets.
- Steam outlet position: Ankle/calf height so steam rises evenly.
- Controls: Clear touchscreen with separate sections for steam, shower, and audio.
- Warranty: At least 2 years on the unit; 5 years on the structure.

Frequently Asked Questions
What’s the difference between a steam shower and a steam room?
A steam shower is a pre-fabricated self-contained cubicle with steam, shower, and other features integrated. A steam room is a custom-built tiled enclosure with a separate generator hidden in the wall. Steam showers are far easier and cheaper to install at home.
Do steam showers need a special electrical supply?
Yes — most home steam showers need a dedicated 32A or 40A circuit, RCD-protected, installed by a qualified Part P electrician. The steam generator draws 2.6–4.5 kW.
How long does a steam shower session take?
Allow 5–10 minutes to build steam from cold, then 15–20 minutes of steam time. Most users finish with a brief cool shower. Total session: about 30 minutes.
Are steam showers good for your health?
Regular steam exposure has well-documented benefits for circulation, sinus and respiratory comfort, skin cleansing, and post-exercise relaxation. Pregnant women, people with heart conditions, and those with severe asthma should consult a doctor before regular use.
Will a steam shower cause damp in my bathroom?
Self-contained steam showers are sealed units, so steam stays within the cubicle. A good bathroom extractor fan handles residual humidity when you open the door without issue.
How often do steam showers need maintenance?
Daily: wipe down glass after use. Monthly: descale the steam generator if in a hard water area. Annually: check seals, descale thoroughly, inspect electrical safety. A well-built unit lasts 12–20 years.
Can a steam shower replace a normal bath?
Steam shower bath combinations do exactly this — the Insignia 1500SR is a 1700mm bath with an enclosed steam shower above, replacing both in one footprint.
Do you deliver steam showers across the UK?
Yes — we deliver across mainland UK. Installation is typically arranged through your own plumber and electrician. Contact us for delivery details and installer recommendations in your area.
