A bathroom renovation is one of the smartest investments you can make in your home. A tired, dated bathroom drags down the feel of an entire property. A well planned bathroom renovation, on the other hand, adds immediate value and makes daily life noticeably better.
The problem is that bathroom costs vary wildly. A basic refresh can be done for around £3,000. A full luxury renovation with underfloor heating, walk in shower, and premium tiles can push well past £15,000. This guide breaks down exactly what drives those numbers so you can budget with confidence before you call a single tradesperson.
A budget bathroom renovation costs £3,000 to £5,000. A mid range renovation runs £5,000 to £10,000. A premium bathroom with all the extras can reach £10,000 to £20,000 or more.
Bathroom Renovation Costs at a Glance
| Budget Level | Total Cost | What You Get |
|---|---|---|
| Budget | £3,000 to £5,000 | New suite, basic tiling, standard fixtures, standard fitting |
| Mid Range | £5,000 to £10,000 | Quality suite, full tiling, thermostat shower, vanity storage, underfloor heating |
| Premium | £10,000 to £20,000+ | Designer suite, large format tiles, frameless glass, freestanding bath, bespoke storage |
Breaking Down the Costs
The Bathroom Suite
The suite covers your toilet, basin, and bath or shower enclosure. This is where budget decisions have the biggest visual impact.
| Item | Budget | Mid Range | Premium |
|---|---|---|---|
| Toilet (close coupled) | £80 to £200 | £200 to £500 | £500 to £1,500+ |
| Basin and pedestal or vanity unit | £100 to £250 | £250 to £700 | £700 to £2,000+ |
| Standard bath | £150 to £350 | £350 to £800 | £800 to £3,000+ |
| Shower enclosure and tray | £200 to £500 | £500 to £1,500 | £1,500 to £4,000+ |
| Shower valve and head | £80 to £200 | £200 to £600 | £600 to £1,500 |
The biggest jump in price comes when you go frameless. A framed shower enclosure at £400 does the same job as a frameless one at £1,500. Both keep the water in. The frameless one looks dramatically better. Whether that difference is worth it depends entirely on your budget and how long you plan to stay in the property.
Tiling
| Type | Tile Cost per m² | Labour Cost per m² |
|---|---|---|
| Ceramic (standard) | £10 to £30 | £30 to £50 |
| Porcelain (mid range) | £25 to £60 | £35 to £60 |
| Large format porcelain (600x600 or larger) | £40 to £100 | £50 to £80 |
| Natural stone (travertine, slate) | £50 to £120 | £50 to £80 |
| Marble effect porcelain | £40 to £90 | £45 to £70 |
Tiling a typical bathroom (walls and floor, approximately 15 to 25 square metres in total) costs £600 to £2,500 in materials and £500 to £1,500 in labour depending on the complexity and tile size. Large format tiles take longer to lay because they need perfectly flat walls. If your walls are uneven, factor in additional prep work.
Plumbing and Labour
| Trade / Task | Typical Cost |
|---|---|
| Bathroom fitter (full fit out, 3 to 5 days) | £1,500 to £3,500 |
| Plumber (pipe alterations, moving waste) | £300 to £800 |
| Electrician (extractor fan, lighting, shaver point) | £200 to £500 |
| Tiler (walls and floor) | £500 to £1,500 |
| Plasterer (if walls need skimming) | £300 to £700 |
| Underfloor heating (electric mat system) | £300 to £700 supply and fit |
| Skip hire or disposal | £150 to £300 |
Labour typically accounts for 40% to 50% of the total bathroom renovation cost. A common mistake is spending heavily on the suite and tiles and then trying to cut corners on the installer. A poor installation of expensive materials looks and performs worse than a quality installation of budget materials. Prioritise the tradesperson.
Extras and Finishing Touches
| Item | Typical Cost |
|---|---|
| Heated towel rail | £60 to £400 |
| Illuminated mirror or mirror cabinet | £80 to £500 |
| Downlights (per light, supply and fit) | £50 to £100 |
| Vanity storage unit | £150 to £800 |
| Shower screen for bath | £80 to £350 |
| Silicone and grout (consumables) | £50 to £150 |
Factors That Affect the Price of a Bathroom Renovation
- Moving the layout. Keeping your toilet, bath, and basin in the same positions keeps costs down. Moving the toilet to a new position means moving the soil pipe, which is a significant extra cost — often £300 to £800 just for the pipework.
- Size of the bathroom. More square metres means more tiles, more time, and more materials. An en suite bathroom costs noticeably less than a family bathroom.
- Condition of the existing room. Old bathrooms often hide damp, rot, or crumbling plaster behind the tiles. If the wall substrate needs replacing before retiling, add £200 to £600.
- Your location. Tradespeople in London and the South East typically charge 20% to 40% more than those in the North of England, Scotland, or Wales.
- Bespoke versus off the shelf. Fitted bathroom furniture made to measure costs significantly more than standard units but makes much better use of awkward spaces.
- Wetroom versus standard shower. A wetroom requires specialist waterproofing of the entire floor and walls. It is more expensive to install but looks exceptional and is easier to clean long term.
How to Save Money on a Bathroom Renovation
- Keep the layout. Do not move the toilet. Do not move the bath or shower position unless you have a very good reason. Every pipe you move costs money.
- Tile the shower area only. You do not need to tile every wall from floor to ceiling. Tiling the shower enclosure and one feature wall, then painting the rest, saves several hundred pounds and can still look excellent.
- Buy tiles from a tile warehouse. Trade tile suppliers and online tile retailers are significantly cheaper than DIY stores. The same tile can cost three times more at B&Q than at a specialist tile warehouse.
- Source your own suite. Many bathroom fitters will fit suite items you supply yourself. Buy direct from a bathroom retailer rather than letting the tradesperson supply everything at a marked up price.
- Electric underfloor heating, not water based. Electric mat systems cost £300 to £600 to supply and install. Water based wet systems cost £1,000 to £2,500. For a bathroom, electric is almost always the better value choice.
- Do the preparation yourself. Strip out the old bathroom yourself before the fitter arrives. This can save one day of labour costs, typically £150 to £300.
- Reuse what works. If your existing bath is in good condition, consider resurfacing it for £150 to £300 rather than replacing it. New taps, a fresh shower screen, and updated tiling can transform a bathroom without touching the bathtub.
Hidden Costs People Forget
- Building regulations. Moving or installing new electrics in a bathroom requires compliance with Part P building regulations. Your electrician should handle the certificate, but check before they start.
- Damp and rot. Damp behind old tiles is extremely common, especially in houses built before 1990. Budget an extra 10% for the unexpected. If you find rot in floor joists, that is a separate job entirely.
- Waterproofing (tanking). A proper shower installation requires tanking boards or a liquid waterproof membrane before tiling. Cutting corners here is how you get damp and mould. Do not let any fitter skip this step.
- Replacing the flooring in adjoining areas. When you pull up bathroom flooring, you sometimes find the junction with the landing or hallway needs attention too.
A bathroom renovation in the UK costs £3,000 to £20,000 depending on the size of the room, the quality of materials, and whether you are moving any plumbing. For most homeowners, a well planned mid range renovation at £5,000 to £8,000 will transform the room completely. Keep the layout, buy good tiles, and do not scrimp on the installer.
Frequently Asked Questions
How long does a bathroom renovation take?
A straightforward bathroom renovation with no layout changes takes 5 to 10 working days. A more complex renovation involving layout changes, a wetroom, or bespoke joinery can take 2 to 3 weeks. You will be without the bathroom for most of that time, so plan access to another toilet and shower in your home or a neighbour's.
Do I need planning permission for a bathroom renovation?
In most cases, no. A like for like bathroom renovation does not require planning permission. However, if you are extending the bathroom into another room, adding a bathroom where there was not one before, or significantly altering the structure of the property, you may need permission. Check with your local council if you are unsure.
Does a new bathroom add value to my home?
Yes, but the returns vary. Estate agents generally suggest a quality bathroom renovation can add 3% to 5% to a property's value. On a £300,000 home, that is £9,000 to £15,000. A mid range renovation costing £6,000 to £8,000 should more than pay for itself when you come to sell.
Should I use a bathroom company or hire trades separately?
Hiring a bathroom company that manages everything is more convenient but typically costs 20% to 40% more than hiring an independent bathroom fitter who coordinates the trades. If you are comfortable managing a small project and getting a couple of quotes for each trade, the independent route saves real money.
What is the cheapest way to update a bathroom without a full renovation?
Re-grouting and resealing costs £100 to £300 and makes a tired bathroom look significantly fresher. New taps are £50 to £200 and take an hour to swap out. A new toilet seat costs £20 to £100. A heated towel rail replaces an old style radiator for £100 to £300. These small changes together can transform the feel of a bathroom for under £700.
