These prices include the cost of removing the existing bathroom, installing new units including bath, handwash basin, WC, vanity unit, fittings, flooring, wall tiling and decoration.
There are several factors that can affect how much getting your bathroom fitted will cost, including:
- where you live
- the age and condition of your property
- ease of access to the plumbing
- how long the job takes
- the quality of fittings and fixtures you want
- whether the bathroom fitter is disposing of any waste for you
- whether additional specialists, such as tilers and electricians, are needed to complete parts of the job.
Ask fitters to break down the quotes they provide so you know what you’re being charged for and whether there’s anything you can save on.
If you’re not getting your bathroom fitted by the company you bought it from, get at least three quotes so you have a better idea of the going rate for the work you want done.

What to consider before starting a bathroom renovation
Before getting started, consider whether your bathroom could benefit from a quick refresh instead of an overhaul, and how extensive any work needs to be:
- You can transform your bathroom without buying a new suite: Painting, regrouting and removing built-up limescale from taps and showers can really make a difference. Upgrading the taps and shower can also be transformative.
- If you’re completely revamping, try to avoid moving plumbing or your waste pipe: This will add cost, so ideally, install a new suite and toilet in the same position as your current ones.
- Weigh up the cost and durability of different products: A cheap bathroom suite may appeal. But it’s not good value if it soon shows wear or breaks. At the other end of the spectrum, a heavy, luxury bath might need a reinforced floor.
- Water efficiency can save you money: Long-term savings can be made by installing products that use less water, such as shower timers and dual flush valves on toilets.
- Good installation is important: Getting your bathroom suite installed properly ensures everything will work and look as good as it should. Use Which? Trusted Traders to find a reliable bathroom installer near you.

Bathroom suite sales
Bathroom retailers run frequent sales, have regular multiple offers and use countdown clocks to encourage customers to order while prices are low.
While this can save you money, make sure you don’t get sucked in by seemingly unmissable headline prices or soon-to-end deals – the savings might not be as great as they appear.
Some companies aren’t always clear about when their promotions will end. They may have at least one promotion running most – or even all – of the time. Some retailers may also confuse shoppers with mix-and-match offers.
- Don’t feel pressured to buy if you’re not sure: take your time to make the right decision for you.
- Make sure that you check the small print: when exactly will the offer end, and what items does the deadline actually apply to?
- If you can’t find the information, speak to a salesperson.
Can a bathroom renovation add value to your property?
Yes, it’s possible to add value by renovating your bathroom, but there are many variables.
According to Which? Trusted Trader William Holden of Holdens Chartered Surveyors & Building Consultancy, you could boost your property value by 2-5% with a new bathroom, but you’re more likely to add value (around 3-7%) if you add an extra bathroom, en suite or downstairs loo.
If resale value is important, opt for light, timeless finishes, and ensure a healthy ratio of bathrooms to bedrooms (two bathrooms for a three-bed home, for example). Plus, the general consensus among experts is that it’s ill-advised to replace a bathtub with a walk-in shower if it’s the only bath in the house – it can be off-putting to buyers with young families.
*In September 2023, we asked 1,129 Which? members about the bathroom suite (bath, toilet and sink) and bathroom furniture they had bought in the previous 10 years, asking about their experiences of trying to save money and their expectations and results around costs.
