Installing a new bathroom in the UK is a significant home improvement project that includes the initial design choices, plumbing and electrical work and room modifications. Costs vary widely depending on the size of the room, the quality of materials, and how complex the installation is.
A new bathroom is a valuable upgrade you can make to your home. As well as improving day-to-day comfort, it can also increase property value and appeal to buyers. However, understanding the bathroom installation process and budgeting correctly is important before starting.
In 2026, the average cost of installing a new bathroom in the UK ranges from around £4,500 to £11,000, with some projects as low as £2,000 and luxury renovations exceeding £20,000.
Installing a bathroom typically takes between 5–10 working days depending on complexity.
This stage includes layout decisions, choosing the right fixtures and making sure you don’t go over budget. Consideration should include keeping the same toilet, bath and sink layout which can reduce costs.
There are a lot of regional and national bathroom suppliers and designers. Choosing the right one will depend on their range and your budget.
If you are on a strict budget or a landlord looking for a quick turn around, Wickes or Victoria Plumbing might suit you. If you want a mid-range quality upgrade then you can check out Roper Rhodes, Hudson Reed or one of the many independent local suppliers on the High Street.
Most High Street sellers offer a design service. Some offer to be project managers supplying their own tradepeople. You might be able to get it installed cheaper elsewhere so make sure you know the cost.

Old baths, sinks, toilets and shower fittings are removed and disposed of. This includes removing tiles and cabinets or shelves if you are doing a total bathroom upgrade.
*If you are feeling brave you might want to do this yourself to save some money but make sure the hired plumber has checked your intentions beforehand. You don’t need a qualification to remove an old bathroom suite but you do need to know what not to remove.
Pipework, drainage, and wiring are installed or modified. Moving these can increase costs but if it is essential for the design, don’t make compromises—Unless it’s the toilet, don’t move that too far if you can help it.
Baths, showers, toilets, and basins are fitted. Timing is important and the fittings need to be in your home before the plumber or installer starts the bathroom installation.
Walls and floors are tiled or panelled, followed by painting and finishing touches. Most plumbers will be able to tile but sometimes it is better to employ a dedicated tiler to get a better finish.

Ways to Save Money
However, cutting corners on plumbing or waterproofing can lead to expensive problems later.
Installing a new bathroom can cost anywhere from £2,000 for a basic DIY refresh to over £20,000 for a luxury installation, with most homeowners spending between £5,500 and £8,000.
The cheapest installations involve minimal changes and budget materials, while the most expensive projects include full redesigns, premium finishes, and bespoke features. Labour remains the biggest cost driver, often making up more than half of the total spend.
Ultimately, the key to a successful bathroom installation is balancing budget, quality, and long-term durability. Spending wisely—especially on skilled trades and waterproofing—ensures your new bathroom not only looks great but lasts for years to come.
