What are Mushroom Kitchens and Why Will They Be Huge?

11 May 2026

A while ago, grey kitchens were everywhere, weren’t they? So much so, in fact, that we flew grey too close to the sun. “Millennial grey” became a cliché that spread to our walls, carpets – even sofas.

Next, greige hit our Instagram feeds harder than Gemma Collins hit the Dancing on Ice rink that one time. Again, though, we overused it. And so greige eventually did the same as grey: plummett.

Now, a new mega trend is emerging. But what is it and, importantly, how do you stay on trend this time without seeing your kitchen befall the fate of grey and greige? The answer: mushroom kitchens.

Let us explain…

Here at Sigma 3, we’ve noticed crowds of homeowners selecting warm, yellower tones this year. The data is clear: beige is the new greige. And while we like beige, it’s, well… beige. It’s not romantic to sell your significant other on the kitchen equivalent of a vanilla candle and a “Live, Laugh, Love” sign.

Nobody wants to be a basic pitch.

Luckily, we have mushroom kitchens – a similarly appealing but more original colour palette. But how did mushroom colour kitchens appear? Why do UK homeowners love them? And how can you design your own mushroom kitchen? Read on for a comprehensive guide on this emerging colour trend.

What is a Mushroom Kitchen?

For clarity, we aren’t talking about the gaudy, fantasy-inspired mushroom décor you sometimes see on Pinterest. Here, mushroom kitchens are a sophisticated alternative to beige.

The “mushroom” name signifies earthy brown-greys – the colour of a portobello mushroom’s soft cap – widely adopted by kitchen manufacturers for cabinetry. Taupe-like, it works well in a neutral palette.

Consider, for example, this Portland Oak pull-out spice rack, or this butler’s pantry with Tuscan Walnut shelves, drawers and pocket doors, nestled under mushroom walls. Both stick to the mushroom palette.

How Did Mushroom Kitchens Appear?

People often joke that history was black and white. In kitchen design, though, it was grey. Dominant for all the 2010s, in many ways, grey kitchens are the apes to mushroom kitchens’ homo sapiens.

Relative to the bolder tastes of the early 2000s, greys initially seemed clean and minimalist – and they were. Indeed, great examples of greys persist today, like this elegant Scots Grey Hatfield range. However, as grey became ubiquitous, kitchen buyers eventually gravitated towards warmer tones.

That brings us to greige. Snowballing to popularity from 2020 to 2023, greige mixed grey with beige, softening the clinical aspects of grey without fully committing to the yellow undertones of beige.

As with grey, we still have a soft spot for greige. Check it out in this Kensington range, for instance. It looks fantastic. A versatile colour, greige pairs well with suedes and mushroom walls in this example to amplify the room’s warmth. That said, it equally suits greyer tones, making it an easy choice for cooler designs. Despite this versatility, however, homeowners eventually craved a creamier aesthetic.

Mushroom Kitchens: An Alternative to Beige

A natural evolution from greige, next came beige – and, thus, here we are: the present day. If you want a safe “timeless” colour option, the most fashionable variation right now is beige. It’ll look brand new but won’t lose much lustre over the long term.

But what do mushroom cabinets have to do with beige? Simply put, in a desert of sandy facades, mushroom is a rich oasis full of life and substance. It’s classy – luxurious in a way that matches cognac and a sable fur coat (faux, of course, Darling).

Mushroom cabinet colours are perfect for those who love a touch of old-money glamour – one that’s pre-digital, that enables you to disconnect from the world and relish in baking a souffle or gossiping with friends over a cup (or five) of nourishing tea. In short, it’s ideal for blocking out the noise of life.

Why Mushroom Kitchens Excel in UK Homes

Many UK houses are designed with south-facing lounges, the goal being to brighten family spaces. As a result, many kitchens are inevitably north facing. It’s the only option when they’re at the back of the building. Unfortunately, this means that cool tones often look colder in British kitchens.

All it takes is a few mushroom cabinets and colour-matching accessories, though, to inject warmth into your kitchen, as lots of British homeowners have discovered. Indeed, mushroom cabinets have emerged alongside beige because they scratch a mental itch in low light: warm, not yellow; earthy, not brown.

What’s more, a mushroom colour kitchen has three benefits: it’s flexible for matching accessories, pale enough to camouflage dust, and ruddy enough to hide missed bolognese stains. Fundamentally, the colour makes your furniture look high-end but be low maintenance for everyday use.

How to Design a Mushroom Kitchen

Designing a mushroom-coloured kitchen to perfection requires less effort than many people think. In fact, just a few simple choices can create you a mushroom kitchen with built-in style and comfort.

1. Use a Warm, Layered Colour Palette

Selecting a colourway in advance is essential because there are two ways to create a mushroom kitchen:

1. Opt for brown-grey cupboards like our Heritage Grey or Farringdon Grey, or
2. Mix a range of colours and lighting accents to achieve the effect of mushroom

Take, for example, the following Highland Stone kitchens for the second method. Combined with Mediterranean flagstones or parquet flooring, plus brown fittings and yellow light, the product of the ensemble creates a mushroom aesthetic, rather than relying on an exact colour match in the doors.

Replace cold greys with browner putty and clay shades where possible. The key is to aim for a natural look. Similarly, consider including antique brass or worn bronze fittings. Both age the room’s look, veering it away from an all-too-clean kitchen aesthetic, instead emphasising relaxation and warmth.

2. Pick Natural Textures

Mushroom is a mineral shade, best used alongside natural textures. Think cut stone, seamed quartz, wood grain. All contribute soil-based notes. And if you want a bolder flash of colourant, try green – either in your cabinets or houseplants. Here at Sigma 3, we’ve covered biophilic kitchens in depth.

When many people think about kitchen design, they only consider the frontage, but pay attention to your drawer boxes. Glimpses of Tuscan Walnut, for instance, can create the effect of having extended the mushroom colour to the cabinets even if the doors aren’t exactly mushroom.

3. Choose a Classic Door Style

A neutral colour on the darker end of the spectrum, mushroom shines most in classic and Shaker kitchen ranges as these styles match the way it promotes cosiness and tradition. As such, we discourage trying to achieve it with modern doors. Often, it’s best to double down on the theme.

Ensure you keep the lighting options warm and veto the vivid colours. In this case, clinical modernity and gaudiness stick out like a neon skyscraper in a Tudor village. The last thing you want to do is drown out the whispering wealth of a mushroom kitchen with new-money bombast.
