We design, supply and install luxury steam rooms across Surrey and South West London – each one created around your home, not adapted from a catalogue. Whether it’s a dedicated steam suite, a hammam, or an existing shower transformed into something far more restorative, the design begins with your space and the way you want to feel in it.
Imagine ending the day in warm, enveloping steam – muscles easing, the noise of the week dissolving – without leaving your home. That’s what we build.
And because steam is the most technically demanding environment in any house, every element – steam-rated waterproofing, ventilation, electrics and finishing – is handled by one dedicated team, under one point of contact, to one agreed plan.
A steam room is only ever as good as its installation – and installations are only ever as good as the team running them.
Your dedicated designer stays with you from the very first conversation through to the first time you step into the steam. They’ll advise not only on the steam room itself but on lighting, finishes and how the space flows with the rest of your bathroom.
You won’t need to coordinate a single trade or chase a single delivery. This is true turnkey design and installation – and it’s why, in 2025, 71% of our projects came from returning clients and trusted referrals.
Your project begins with an exclusive, no-pressure consultation at our Long Ditton showroom. You’ll have dedicated time with one of our award-winning designers to discuss your space, your wellness goals, and what’s possible.
We design your steam room around your home and the way you live – from a full bespoke steam suite to converting an existing shower into a hammam.
Structural work, steam-rated waterproofing, electrics, plumbing, ventilation and tiling – every trade scheduled, supervised and signed off by us.
We walk you through your finished steam room, your generator controls and simple care guidance before a single detail is signed off.
Every BK11 installation is backed by our eleven-year workmanship guarantee. Steam is demanding. Our standards are more so.
A dedicated steam suite, designed to the exact proportions of your space and finished to complement your home – whether a grand period property or a contemporary new build.
Even an ordinary shower can become a hammam. We integrate Effe steam generators into existing or new shower enclosures, bringing humid heat, relaxation and ritual into the footprint you already have.
Steam pairs beautifully with sauna, UV and infrared. Many of our clients combine elements into a single wellness space – we’ll design around what your body and your routine actually need.
We partner with Effe, the Italian masters of home steam, whose generators and hammams trace their origins to bathing traditions thousands of years old. Their technology delivers the dry or humid heat that flushes out toxins, eases muscles and restores a sense of calm that’s hard to find anywhere else in a modern week.
Technology this refined deserves installation to match. With over 100 wet rooms completed, our team understands steam-heavy environments better than almost anyone in Surrey – the substrates, the sealing, the ventilation that keeps a steam room performing year after year.
If you’ve been imagining a private steam retreat, a consultation at our Long Ditton showroom is the natural first step.
Yes. Effe’s generators and hammam systems are designed to adapt to almost any space – including converting an existing shower enclosure. During your showroom consultation we’ll assess your space and recommend exactly what’s possible.
Humid heat helps flush out toxins through perspiration, relax tired muscles, and ease everyday stress – a natural, enjoyable way to support your wellbeing, used for thousands of years.
We do. Every trade is coordinated and managed by your dedicated BK11 team under one point of contact, from structural preparation to final styling.
