A separate shower room was at the top of Keeley Wilson’s wish list after six years of sharing a family bathroom. ‘Our kids love showers and our bathroom was becoming too crowded at busy periods,’ she says.

As part of a substantial two-storey extension, she got the chance to change the cloakroom into a shower room. ‘It wasn’t massive and we knew we’d have to be clever with the design.’

Putting wallpaper on just two walls makes a dramatic impact, but stops it feeling oppressive and closed-in. Keeley has chosen a plain wooden blind for the window as a contrast to the burst of colour

A window was an essential and the couple carefully planned the potential layout. ‘Because of the position of the door, the shower had to be to the right. So it was easy to see the right spots for the sink and toilet.’

A bit about me...

Who lives here? Keeley Wilson, 41, a hair and make-up artist, lives in a three-bedroom 1930s semi in Hampton, south-west London. She lives with her husband, Alan McKenna, 47, an actor, son Archie, 11, and daughter, Violet, seven, as well as their dog, Harper.

What was wrong with the old bathroom? ‘It was tiny with an old beige sink and toilet, and no window. There was no storage and it was dark and dingy.’

Keeley chose a contemporary basin and toilet and wanted them both to be set into units and up off the floor, but couldn’t find exactly what she wanted online.

‘I had a stroke of good luck because a friend was re-doing her bathroom and had two white units she didn’t want. I knew I could upcycle them and get the builder to adapt them.’

‘Spend money where it’s important – the shower, toilet, basin and tiles – but look out for items you can upcycle’ says Keeley

With the pieces in place, it was time for Keeley, who works with colour all day long in her business, The Beauty Collective, to add her signature touch. ‘Every decision came from the floral wallpaper,’ she says.

With a strong wallpaper, rather than sticking to one shade for your towels or going pale, pick out several instead. Hang them on hooks to create separate blocks of colour throughout the room

Picking out the shocking pink for the units, Keeley painted them in a traditional oil gloss. ‘I was thrilled with the way they came out – they look like designer items. No-one can believe that I didn’t buy them in a swanky shop.’

A bit about my bathroom...

What do you like most about the bathroom? ‘The fact that it’s so colourful and vibrant. The wallpaper was the starting point for the whole scheme. I bought it before any work started and I still love it.’

Opting to keep two of the walls plain white, Keeley searched for tiles to go inside the shower and above the basin as a splashback.

‘I wanted a deep, luxurious greeny blue with a shine and I found a colour that was within the wallpaper. Because of that, I kept the floor tiles white, although I did choose a big format to make it feel bigger.’

A high-quality square shower enclosure fits snugly in the corner and the minimal chrome lessens the impact. The stunning green tiles carry on the colourful flair, as well as protecting from splashes

The wallpaper also led Keeley to choose towels in bold colours, as well as fun accessories in yellows, pinks and blues. ‘We all love it in there now.’
