I love wallpaper, but for a long time I assumed that using it in a toilet or bathroom was asking for trouble.

Then we started transforming our very ordinary new-build downstairs WC.

The room had the typical magnolia walls (or almond white, as they call it these days) that came with our Barratt new-build home. It was clean and functional, but it felt completely generic. I wanted something softer, warmer and much more like our home, so we introduced sage green, floral wallpaper and a few simple decorative touches.

The result was exactly what I was hoping for — but it also raised an important DIY question:

Can you protect wallpaper from water and moisture in the toilet?

Can You Use Wallpaper in a Downstairs Toilet?

A downstairs WC is a particularly good place to experiment with wallpaper because it doesn't have the same level of constant steam and moisture as a bathroom with a bath or shower.

However, wallpaper and water still aren't the best combination. If you are using wallpaper in a moisture-prone room, it's important to choose the right product and think carefully about where it will be installed.

For our makeover, the wallpaper wasn't being used inside a shower or in an area exposed to constant water. Although it was installed around the sink and it was always going to get splashes of water, so we wanted to make sure our decorative feature that completely changed the character of the room would last.

I also wanted to give the wallpaper some additional protection, which is where a clear wallpaper sealant/decorator's varnish came in.

How I Protected the Wallpaper

Once the wallpaper was installed and completely dry, I applied a clear protective sealant designed for use on wallpaper.

The idea isn't to turn ordinary wallpaper into a waterproof shower wall. Instead, the protective coating adds another layer of resistance against everyday moisture, occasional splashes and marks.

Before using any sealant, always check that it is suitable for your particular wallpaper and follow the manufacturer's instructions. It is also a good idea to test the product on a small, inconspicuous area first, as some coatings can affect the appearance, colour or finish of wallpaper.

For our downstairs toilet, this felt like a simple extra step that was worth doing.

Why I Chose Floral Wallpaper for Our New-Build WC

The biggest transformation wasn't actually the sealant — it was the wallpaper itself.

New-build homes can sometimes feel quite uniform, particularly when you first move in. Adding pattern was an easy way to introduce some personality without replacing the bathroom suite.

I chose a floral, botanical-style wallpaper and paired it with sage green to create a calm, nature-inspired look.

I love how the floral pattern softens the room while the green helps it feel connected to the rest of our home.

We also added couple of picture shelves, similar to IKEA Mosslanda for a little extra storage and styling space.

Suddenly, the room that had once been one of those spaces we barely noticed became one of my favourite little transformations in the house.

How to Protect Wallpaper in a Downstairs Toilet

If you're thinking about trying something similar, these are the steps I'd recommend:

1. Choose the right wallpaper

Look for wallpaper that is appropriate for your intended space and check the manufacturer's guidance regarding moisture and bathroom use. I love statement floral wallpaper in any small toilet, it absolutely transforms it.

2. Prepare the wall properly

Make sure the wall is clean, smooth and dry before hanging your wallpaper. Any imperfections can become much more noticeable once the wallpaper is installed.

3. Keep wallpaper away from direct water

A downstairs WC is very different from a shower enclosure. I would not treat ordinary wallpaper as suitable for areas that receive constant direct water exposure like shower room or for any wall around the bath.

4. Allow the wallpaper to dry completely

Don't rush the sealing stage. Make sure the wallpaper and adhesive are fully dry before applying any protective coating.

5. Apply the appropriate sealant

Use a clear sealant or decorator's varnish that specifically states it is suitable for wallpaper. Follow the manufacturer's application instructions and drying times.
I chose below varnish with clear Satin finish, you can also choose between gloss and flat.

6. Look after the finished wall

Even protected wallpaper isn't indestructible. Avoid unnecessary water exposure and deal with splashes or marks promptly rather than allowing moisture to sit on the surface.

Would You Try Wallpaper in Your Downstairs Toilet?

If you've been putting off decorating your downstairs WC because it feels too small or too boring, don't underestimate what you can do with a little colour and pattern.

A small cloakroom can actually be the perfect place to experiment.

For us, replacing those plain magnolia walls with sage green and floral wallpaper was enough to turn a generic new-build toilet into a cosy little room that finally feels like part of our home.

From Bland New Build to Characterful Cloakroom

This little project reminded me that you don't need to completely renovate a room to make it feel different.

Our downstairs toilet still has the same toilet and basin. We didn't knock down walls or spend thousands on a bathroom renovation because, for us, that felt completely unnecessary.

We try to be mindful with the decorations and renovations we make in our home. Practicality comes first, and looking nice comes second.

We want our home to feel practical, cosy and homely — not like the shiny show homes you see all over Instagram and TikTok that look beautiful but wouldn't necessarily feel like us.

For us, making a home isn't about following every trend or creating a picture-perfect space. It's about adding little details that make the space work better for us and make us happy to live in it.

In this room, it was as simple as introducing sage green, floral wallpaper and a couple of shelves. Nothing dramatic. Nothing extravagant. Just a few thoughtful changes that made a generic new-build WC feel much more personal.

We changed the things that make a room feel like your home: colour, pattern, texture and thoughtful details.

The sage green, floral wallpaper and simple shelving completely changed the atmosphere.

And that's exactly what I love about DIY — sometimes a relatively small project can make an unexpectedly big difference.

And that's really what It's Called Home is all about.
