Right, so you're staring at that tiny 5×10 bathroom, thinking a spruce-up is overdue, but the big question is… how much is this little project actually going to sting the wallet? Blimey, I've been there. Let me tell you about my mate Sarah's place in Clapham last autumn. She had this identical-sized loo, all 1970s avocado suite and damp patches. She thought, "How hard can it be?" Well.
First off, chuck that online "bathroom cost calculator" out the window. They're about as useful as a chocolate teapot. A 5×10 bathroom remodel cost isn't a single number you pluck from the sky. It's more like a recipe where you choose every bloomin' ingredient, and the price tag swings wildly. Is it a basic refresh or a full-on gut job? That's the million-dollar… or rather, the several-thousand-pound question.
Think about what you're keeping. Sarah made the classic mistake. She wanted to keep the old cast-iron tub to save money. Sounds smart, yeah? But once the chaps started, they found the plumbing behind it was, and I quote the builder, "a proper botch job." That "save" vanished faster than my motivation on a Monday morning. So, rule one: budget for nasty surprises. I'd say, mentally add at least 15-20% on top of whatever figure you land on. For a compact space, hidden issues are almost a given because everything's so cramped.
Now, the big-ticket items. The suite itself. You can get a decent white close-coupled toilet and a basic basin for under £500 if you shop around. But oh, the taps! That's where personality—and cost—creeps in. A sleek, wall-mounted mixer tap versus a standard pillar tap? Could be triple the price. And the shower! In a 5×10, you're likely looking at an over-bath shower. A good thermostatic bar mixer valve is worth every penny for safety, but it adds up. Sarah went for a fancy rainfall head and separate handset. Looked lush, but the plumbing labour to fit it properly? Ouch.
Then there's the tiles. My personal favourite bit, but a proper rabbit hole. You can get perfectly serviceable ceramic tiles for £20 per square metre. Or you can fall in love with those handmade, glazed Moroccan zellige tiles at £120 per square metre like I did for a project in Chelsea. The difference on your walls and floor is staggering. For your floor, in a small space, I'd avoid large-format tiles—more cuts, more waste, more labour. Go for smaller ones or even vinyl plank that looks like wood. Warmer underfoot, too.
Labour. Crikey, this is the beast. In London right now, a good, licensed plumber and a proper tiler aren't cheap. And you need both. A general builder might do it all, but check their specific skills. For a full 5×10 remodel—stripping it out, new plumbing, electrics (got to have that extractor fan and downlights!), tiling, plastering, painting—you're looking at probably 10-14 days of work for a two-person team. At day rates… well, do the maths. It adds up quicker than you can say "skip hire."
So, how do you actually calculate it? Break it down, love. Literally get a notepad.
* **Demolition & Skip:** £300-£500.
* **New Suite (toilet, basin, bath):** £500 – £3000+ (be honest with yourself here).
* **Taps & Shower Valve:** £200 – £1500.
* **Tiles & Flooring (materials):** £400 – £2500.
* **Labour (plumbing, tiling, building):** £4000 – £8000+.
* **Electrics & Lighting:** £500 – £1000.
* **Extras (mirror, cabinet, towel rail, paint):** £300 – £1000.
See? For a mid-range, decent quality job where you're not cutting corners but not splashing on gold-plated taps either, you're easily looking at **£8,000 to £15,000** for that 5×10 bathroom remodel cost. Sarah's ended up around £11,500. And that was with her doing the painting herself!
My final twopence? Don't scrimp on the water-proofing (tanking) for the shower area or the extraction. A mouldy bathroom in a year's time is heartbreak. And buy all your materials *before* the builders start. Delays cost money. Oh, and make friends with your local independent tile shop—their advice is often worth more than the tiles.
It's a journey, honestly. Frustrating, exciting, dusty, but when you're finally having a cuppa in a bath in a space that actually feels like *yours*… well, you almost forget the invoices. Almost.
