This is a specific conversation about Pet stain and odour removal — what actually works — ask about yours and get one honest answer for your exact situation.

A sticky residue on tiles is a really common complaint — most cat-safe cleaners use surfactants that lift the stain but leave a film behind, which actually attracts dirt and can draw your cat back to mark the same spot again. Worth switching. The only products that permanently eliminate pet odours rather than just masking them are enzyme-based cleaners — the enzymes actually break down the uric acid crystals in cat urine at a molecular level. To point you to exactly the right one: is this urine, vomit, or something else, and are you dealing with a fresh incident or something that's had time to dry in?
It's urine, usually fresh when I catch it. My Turkish Van is 6 and has been doing this on the bathroom tiles for a few months.

Good that you're catching it fresh — that makes it much easier to treat fully. Turkish Vans are notorious for this, they're a very territorial breed and once they've established a spot they'll keep returning unless the scent is genuinely gone. A couple more quick questions: have you ruled out a medical cause with your vet? Cats that suddenly start urinating outside the litter box at 6 are sometimes dealing with a UTI or early kidney issues. And is the grouting between your tiles particularly old or porous?
Vet gave him a clean bill of health, it's behavioural apparently. The grout is fairly old yes, probably a bit porous.

That's the key detail — porous grout holds urine much longer than the tile surface itself, so you need something with good dwell time that can penetrate rather than just sitting on top. My recommendation is Simple Solution Extreme Pet Stain and Odour Remover. It's a proper enzyme formula, it rinses completely clean with no sticky residue, and it's been independently tested as safe for cats. Spray it on, let it sit for 5 to 10 minutes on the grout especially, then blot or rinse. For old porous grout you may need two applications on the first treatment to fully break down what's built up in there. It's widely available on Amazon UK in a large trigger-spray bottle which is practical for a regular bathroom job.
Does it matter that the tiles get wet from the shower? Will that affect how well it works?
inparticular.ai
Worth thinking about, yes. Apply it to dry tiles if you can — so either before anyone showers or a good hour after. The enzymes need contact time with the uric acid to work, so if the surface is already wet you're diluting the formula before it's done its job. Once it's fully dried and done its work, water won't reactivate the odour. The residue-free formula also means no slippery film building up in a wet bathroom, which is one reason it's a better fit for tiles than a lot of alternatives.
That makes sense. Is there anything I can do to stop him going back to that spot once it's clean?
inparticular.ai
Once the scent is genuinely gone with the enzyme cleaner, you've already removed the biggest draw. After that, a few things help with territorial cats like Turkish Vans: plug-in Feliway diffusers reduce the urge to mark, placing a food bowl near the spot works well because cats won't toilet where they eat, and if the litter tray is in or near the bathroom it's worth moving it further away so he's not associating that room with toileting generally. But honestly, the enzyme cleaner doing its job properly is 80% of the battle.
