If you’re planning a bathroom revamp, one of the first and most important questions to ask is how much does a bathroom renovation cost?
In reality, there isn’t a one-size-fits-all answer. Bathroom renovation prices can really vary. The final cost will depend on the size of the space, the fixtures you choose, and the complexity of the work actually involved.
In the UK, a bathroom renovation can start from as little as £5,000, with more extensive remodels likely to cost significantly more. If you want to stay on track without overspending, you’ll need to plan (and stick to!) a clear budget.
What’s the average cost of a bathroom renovation?
On average, bathroom renovations in the UK typically start from around £5,000, but they can scale up. It all depends on what options you go for and the level of luxury you want to achieve. A full refit with premium fittings or luxury finishes could push the budget into the tens of thousands.
Bathroom cost by renovation level
Basic/budget renovation
This option is perfect if you just want to freshen up your bathroom or en-suite without a major overhaul. These types of projects usually focus on:
- Replacing outdated taps, showerheads, or handles
- Painting or re-tiling small sections
- Updating lighting
- Installing a new toilet or basin without altering the plumbing
If you’re a landlord refreshing a rental property, or a homeowner who wants a clean, functional bathroom without splashing out, this route could be a good option.
Mid-range renovation
This is the most common bathroom project in UK homes. It usually includes things like:
- Installing a new bath or walk-in shower
- Full re-tiling of the walls and floors
- Installing a modern sink, toilet, and lighting
- Improved storage solutions
Mobility-friendly options are increasingly popular in this price range. For example, you might consider installing a walk-in shower or a walk-in bath for added safety and accessibility. Both of these options can also provide long-term value.
High-end/luxury renovation
If budget isn’t an issue, a high-end remodel can deliver a bathroom that feels like stepping into the spa at home! These projects often include:
- Bespoke cabinetry and high-quality tiling
- Premium fixtures, such as freestanding baths or rainforest showers
- Underfloor heating
- Wet-room conversions with specialist flooring
- Custom lighting and luxury finishes
When it comes to budget, the sky’s the limit!
What are the factors that influence bathroom renovation cost in the UK?
How much does a bathroom renovation cost? Aside from the general categories above, several factors will have an impact.
These include:
- The size of your bathroom
Renovating a larger bathroom will cost more due to additional materials and labour time required.
- Choice of materials
If you want to install designer tiles, marble, or bespoke furniture, these items can significantly increase spend when compared to basic ranges.
- Plumbing and electrics
Moving water pipes, adding power showers, or upgrading electrical wiring will add complexity, making your project more expensive overall.
- Fixtures
From budget-friendly suites to luxury walk-in baths, the fixtures you choose will affect final costs.
- Labour rates
These vary by region – for example, bathroom fitters in London and the South East typically charge more.
- Layout changes
Keeping your existing bathroom layout is likely to be cheaper. Moving a toilet or shower can increase plumbing and other expenses.
Hidden or additional costs to watch out for
Even with plenty of planning, unanticipated expenses can easily crop up. Here are a few things to be mindful of:
- Waterproofing and tanking are essential for showers and wet rooms to prevent leaks.
- Structural repairs. If you’re updating a bathroom in an older property, issues like damp, rot, or uneven floors may be identified during the renovations.
- Permits and building regulations. If your project involves making changes to the plumbing or structural changes, you may need to obtain building control approval.
- Waste disposal. Skip hire and disposal charges aren’t usually included in material prices.
Most experts recommend adding a 10-15% contingency fund to your budget. Doing so means you’ll be covered if unexpected surprises arise.
How to budget for a bathroom renovation
Budgeting effectively is vital to ensuring your bathroom remodel goes smoothly. You can achieve this by:
- Setting clear priorities.
At the start of the project, decide what matters most to you – whether that’s luxury aesthetics, safety features, or simply a refreshed appearance.
- Balance cost and value.
Depending on your circumstances, spending money on a durable, safe, walk-in shower could be more worthwhile than luxury tiles.
- Don’t forget running costs.
Underfloor heating, for example, has ongoing energy costs to consider. Remember to build in a contingency fund of at least 10 to 15% over your estimated spend.
Smart ways to save money without compromising quality
A stylish bathroom doesn’t have to come with a luxury price tag. You can save money in a few different ways.
Mixing high and low-end finishes is a good way to reduce the cost of your project. For example, you could opt for statement tiles in one area, paired with more affordable plain tiles elsewhere.
It’s also best to reuse the existing layout of your bathroom (leave the toilet, sink, shower, and bathroom in the same place). This avoids the need to move the plumbing, which is one of the biggest cost drivers.
If you’re budget-conscious (and not worried about your bathroom being on-trend!), make sure you shop around sales and clearance ranges. Many bathroom retailers offer hefty discounts on last season’s styles.
Finally, using your DIY skills for some of the smaller tasks can help to save a few pounds. Tasks like painting, fitting mirrors, or upgrading cabinet handles are fairly straightforward jobs that you might be able to handle yourself instead of paying a professional.
Why professional installation matters
Some tasks might feel easy to DIY, but a full bathroom renovation is almost always worth leaving to the professionals. Expert installers can spot potential issues before they become costly mistakes, ensure waterproofing and plumbing are done correctly, complete the job faster with less disruption, and provide guarantees on their work.
For all of these reasons, professional fitting usually saves money in the long run by avoiding expensive call-backs and repairs.
If you’re renovating your bathroom, understanding the key cost factors, planning ahead, and setting a realistic budget with a contingency fund are key. Whether you want a budget-friendly bathroom refresh, a mid-range remodel, or a luxurious spa-style bathroom, knowing your options is the first step to creating a beautiful and practical bathroom or wet room.
