WOW!house 2026: Luxury Bathroom Design Trends Live From Design Centre Chelsea Harbour

If you work in interiors or you are in the middle of planning a bathroom renovation in London and you want to know what design excellence actually looks like right now, WOW!house is the event to have on your radar.

Now in its fifth year, WOW!house takes place at Design Centre Chelsea Harbour every June and is widely regarded as one of the most important events in the UK interior design calendar. Twenty-one rooms. Twenty-one A-list interior designers. Each one given a full-scale space to create, style and bring to life in collaboration with world-class brands, with the result being an immersive showhouse you walk through like a real home. This year it runs from 2 June to 2 July 2026 and the designer lineup includes names like Francis Sultana, Rigby & Rigby, De Rosee Sa and Russell Sage Studio.

This is where the design world gathers. It is where ideas are born, where collaborations are sparked and where the bathrooms and interiors of the future get their first audience.

Why Kallums Bathrooms Will Be There

At Kallums Bathrooms, we do not just supply beautiful bathrooms. We work alongside interior designers, architects and homeowners across London and Surrey who care deeply about the detail, people for whom a bathroom is not an afterthought but one of the most considered spaces in a home. Events like WOW!house are where we go to stay sharp, stay current and stay genuinely inspired by where luxury bathroom design is heading. We walk those rooms the same way you do: looking, absorbing, questioning. And then we bring what we find back into our work.

Whether you are an interior designer or architect keeping a close eye on emerging bathroom trends, or a homeowner who is deep in the planning stages of a luxury bathroom renovation, this is the kind of event that shapes the conversations we will be having with you. The trends we spot, the details that stop us in our tracks, the material combinations we had not considered before – all of it feeds directly into how we design and what we recommend.

Bathroom Design Inspiration for 2026 and Beyond

WOW!house is not just a showcase. For us it is research. It is the place where we see how the world’s best interior designers are approaching space, light, texture and finish and where we start to understand which luxury bathroom trends are genuinely gaining momentum and which are simply noise. That knowledge comes back to our showrooms in Putney and Guildford, and into every bathroom design conversation we have with clients.

Our next blog will go deeper: what we saw, what moved us and what we think is quietly shaping the future of luxury bathroom design in London and beyond. Watch this space.
