If you’re dreaming of a brand-new bathroom with spa vibes, sleek storage, or maybe just a toilet that doesn’t gurgle when you flush — you’re not alone. A bathroom renovation can be one of the most satisfying home upgrades. But let’s talk about what everyone wants to know when their considering a new bathroom: What’s the average cost of a bathroom renovation in the UK in 2025?

Spoiler alert: it varies, but as seasoned pro when it comes to carrying our bathroom renos (we have 4 under our belt now), I’m here to break it down for you. Whether you’re sprucing up a tired loo or planning a full-on bathroom transformation with underfloor heating and rainfall showers, this guide covers everything you need to know.

So, What’s the Average Cost of a Bathroom Renovation UK?

In 2025, the average cost of a bathroom renovation in the UK typically falls between £5,000 and £10,000. That said, you can renovate a small bathroom on a budget for as little as £3,000, or splash out £15,000+ for a luxurious, high-spec upgrade.

Let’s break that down a bit more:

Key factors that affect cost include:

• Size of the bathroom

• Quality of materials and fixtures

• Whether you’re moving plumbing or electrics

• Labour costs in your area

• Whether you’re doing any of the work yourself

Budget vs Blowout: What Does That Money Actually Get You?

Budget (£3,000 – £5,000):
You can expect:

• A fresh lick of paint

• New taps or a toilet

• Basic tiling

• A new bath or shower screen from budget retailers like B&Q or Wickes

Think of this as the “make it nice and clean” level of renovation — ideal if you’re renting out a property or getting it ready to sell.

Mid-Range (£5,000 – £8,000):
This is where most UK homeowners land. You’ll get:

• A full strip-out and replacement

• New suite (bath, basin, toilet, shower)

• Tiling and flooring

• Stylish fixtures from brands like Victoria Plum or Soak

• Some light plumbing or layout changes

This option is perfect if you want your bathroom to feel fresh and modern — think clean lines, decent tiles, maybe even a touch of marble effect.

Luxury (£8,000 – £15,000+):
Now we’re talking walk-in wet rooms, backlit mirrors, custom shower doors, underfloor heating, and maybe even a Japanese-style smart toilet. Expect:

• High-end materials (think porcelain tiles, stone basins, copper taps)

• Designer fittings from places like CP Hart

• Fully customised layout and lighting

This is the ‘treat yourself’ option — ideal for your forever home.

Hidden Costs You Might Not Have Thought About

It’s not all tubs and tiles. Here are a few sneaky extras that can add to the average cost of a bathroom remodel UK:

• Skip hire and disposal: Removing your old suite and tiles isn’t glamorous, but it needs doing. Budget around £200–£300.

• Plumbing and electrics: Moving pipes or adding sockets? It adds up fast — typically £300–£800.

• Ventilation: Don’t skimp on a good extractor fan (especially if you don’t fancy mouldy grout in six months). Expect to pay around £100–£300.

• Unexpected repairs: Leaky pipes, rotten floorboards — once you pull up tiles, you never know what you’ll find. It’s wise to set aside 10–15% of your total budget for contingencies.

DIY or Professional?

Tempted to get your hands dirty to save money? Fair enough — just know where to draw the line.

You might be able to:

• Paint the walls

• Assemble flat-pack vanity units

• Do your own tiling (if you’re brave and YouTube-savvy)

Leave it to the pros for:

• Plumbing and gas work (which legally must be done by a qualified engineer)

• Electrical installations (especially if near water)

• Large-scale tiling or tanking (for waterproofing)

Hiring a bathroom fitter can cost £150–£250 per day, depending on location. In London and the South East, expect to pay more. Always check if they’re registered with a trade body like FMB or TrustMark.

How to Save Money Without Sacrificing Style

Renovating doesn’t have to break the bank. Here are a few cheeky tips to keep costs down:

1. Keep the layout the same – Moving your toilet across the room may double your plumbing bill.

2. Shop smart – Sales at Screwfix, Wickes, and even IKEA can save you hundreds.

3. Mix and match – Pair budget units with a statement mirror or designer taps to get that “expensive” look for less.

4. Use wall panels instead of tiles – Quicker to install, cheaper, and less faff when it comes to grout.

5. Do the decorating yourself – A decent roller and some waterproof paint can make a big difference.

Should I Renovate My Bathroom Before Selling?

Absolutely. A modern bathroom can add up to 5% to your home’s value — and it’s often one of the first rooms buyers check out on a viewing.

That said, don’t go overboard. A tasteful, mid-range refit will appeal to more buyers than a quirky, high-end luxury suite that might not be to everyone’s taste. If you’re planning to sell soon, stick to:

• Neutral colours

• Durable finishes

• Simple, timeless fittings
