This is a specific conversation about Cat litter boxes — size, type, and placement — ask about yours and get one honest answer for your exact situation.

Bringing home a 10-year-old shelter cat is wonderful — and the litter box setup genuinely matters here because you have no idea what they've been used to. Quick background first: most litter boxes are too small. Cats need a tray at least 1.5 times their body length to feel comfortable, and covered boxes — though tidier for us — often make cats feel trapped, which is the last thing you want for a cat already adjusting to a new home. So: how big is your cat, are there any other cats in the house, and have you noticed any hesitation or avoidance around the litter box since they arrived?
She's a medium-sized tabby, probably around 4kg. She's the only cat. We've only had her three days and she used the box the shelter sent us once, but she seems a bit nervous about it — sniffs it, walks away, then eventually uses it. The shelter box has a lid on it.

That hesitation is really telling — sniffing and walking away before eventually using it is a classic sign a cat doesn't fully trust the box. The lid is almost certainly part of the problem. Older shelter cats especially can feel ambushed in covered boxes; they can't see threats coming and the smell builds up inside. I'd ditch the lid immediately. Can you tell me where the box is currently placed — is it in a quiet corner, or somewhere with foot traffic or noise nearby?
It's in the bathroom, fairly quiet, but the washing machine is in there too. We run it most mornings.

The washing machine is almost certainly spooking her — a sudden loud spin cycle while she's mid-use is exactly the kind of thing that creates lasting litter box aversion in cats, especially anxious ones. Moving the box away from the machine, or to a different quiet spot altogether, will help a lot. For the box itself, my recommendation is the Petmate Open Cat Litter Pan in large. It's genuinely spacious — right for a medium cat — fully open so she can see her surroundings in all directions, low-sided at the front for easy entry which matters more as cats age, and it has a high back to contain scatter. Simple, no fuss, nothing to startle her. It's consistently well-reviewed and easy to find on Amazon UK. Pair it with an unscented clumping litter — scented ones often put older cats off — and place it somewhere she can approach from multiple angles.
That makes so much sense about the washing machine, I hadn't even thought of that. Should I swap everything at once or do it gradually?

Gradually is better. Move the existing box away from the washing machine first — even just to the other side of the bathroom or into a bedroom corner — and let her find it there. Once she's using it reliably, introduce the new open tray alongside the old one. Put a small scoop of used litter from the old box into the new one so it smells familiar. Most cats switch within a few days when they can see the new box is safe. Don't remove the old box until she's using the new one consistently. For a newly adopted senior cat, keeping stress low during the transition is more important than speed.
Perfect, that's really helpful. I'll move it today and order the tray.

Good plan. Give her a week with the new setup and I'd expect the hesitation to disappear. If she's still nervous after that, it's worth checking whether the litter type is a factor — some cats, especially older ones, have strong preferences for fine-grained unscented clumping over coarser or pellet-style litters. But start with the box move and the open tray — those two changes alone sort out the majority of cases like this.
