Through meticulous planning, you can ensure that your bathroom renovation aligns with your vision and budget. Our comprehensive guide breaks down the necessary budget for a bathroom makeover, taking into account the latest trends and ensuring that you are well-informed before taking the plunge.

Understanding the costs involved is crucial for a successful renovation journey. With our expert advice, we aim to empower homeowners like you to confidently plan and execute a bathroom renovation that not only meets your expectations but also aligns with your financial considerations.

We acknowledge the significance of a dream bathroom for you and your family. Our mission is to assist you in taking a substantial step closer to turning that dream into a tangible reality. As you navigate the world of bathroom renovation costs, we trust our guidance to provide clarity on current bathroom makeover trends and other essential considerations so you can start on a bathroom remodelling project with confidence and enthusiasm.

Understanding The Average Cost Of A New Bathroom

According to Check-a-trade, UK bathroom remodelling costs lie between £4,000 and £5,000 on average. However, high-end, bespoke bathrooms can be more than double this figure. Equally, you can save money by buying off-the-shelf products and doing some of the planning and design work yourself. Your choice will naturally depend on how much you can, or want to, spend on the project.

Actual bathroom renovation prices will vary depending on the size of your bathroom and the scope of the project. A total bathroom redesign will of course cost more than simply redecorating your space. New fixtures and fittings will add to the cost too. A top-end stand-alone bathtub could set you back a few thousand pounds alone, for example. Luxury touches such as underfloor heating and walk-in shower enclosures will also push your budget skyward.

New bathroom installation costs are an important element when it comes to the average cost of a new bathroom. Again, according to Check-a-trade it typically takes between five and ten days for a team of tradesmen including plumbers, electricians, fitters, plasterers, tilers and decorators to install a bathroom. Hourly rates vary, but it is important to consider labour in your budgeting. Paying for installation labour is always a significant proportion of the average bathroom remodel costs. Forgetting it, or underestimating it, can prove a costly error.

Baths and Showers

The cost of purchasing a new shower or bath can vary widely. A basic acrylic tub or shower unit may start at around £150 to £200. More luxurious options like a freestanding tub or a custom shower enclosure can cost upwards of £1,000. A freestanding natural stone tub could be more still.


A standard toilet can range from £100 to £500, depending on the brand and features. High-end toilets with advanced technology or unique designs can cost double or even triple this amount.

Bathroom Sinks

The cost of a bathroom sink and vanity unit varies based on the material, size, and design. A basic unit might start at around £150, while a custom or designer option could set you back ten times that figure.

Tile Flooring

Tile prices range widely depending on the type and quality. On average, ceramic tiles can start at £20 per square metre, while high-end porcelain or natural stone tiles can go up to £100 or more per square metre.

Vinyl or Laminate Flooring

If you’re on a tighter budget, vinyl or laminate flooring is a more cost-effective option. You don’t have to compromise on style. You might choose tile effects or stone patterns, for example. Both start at around £10 per square metre.


Basic ceiling lights can start at as little as £20 while stylish or designer fixtures may cost several hundred pounds. Adding additional lights around the bathroom, say in mirror surrounds, can enhance both functionality and aesthetics. Individual lights typically range from £50 to £200 or more.

Plumbing and Electrical Work

The cost of plumbing work will depend on the complexity of the project. Replacing fixtures or moving plumbing lines can increase the overall cost. On average, plumbing costs can range from £500 to £3,000. The cost of any electrical work required, such as installing new lighting or outlets, might similarly range from £500 to £3,000 or more depending on the scope of the project.

Having a New Bathroom Fitted: Top Tips

A bathroom renovation need not break the bank. If you have calculated your dream bathroom refit costs and ended up with a figure that’s at the top end of your budget, don’t panic. There are several strategies you can adopt to keep costs in check without compromising on quality. We have shared a selection of the most useful ones below.

DIY Where Possible

If you have the skills, consider tackling some tasks yourself. Painting, simple tiling, or assembling flat-pack furniture can be DIY projects that save on labour costs. It is worth pointing out that electrical and plumbing mistakes can end up costing a lot to rectify so these tasks are probably best left to the professionals.

Shop Around for Materials

Don’t settle for the first option you find or your installer recommends. Thanks to the internet, it is incredibly easy to compare prices at different suppliers these days. It pays to look for sales or clearance items too. Reducing the estimated cost of a new bathroom by picking up a bargain always feels great.

Consider Mid-Range Options

Opting for mid-range materials and fixtures can help strike a balance between quality and cost. You don’t always need the most expensive options to achieve a beautiful and functional bathroom. Many big brands and national chains have cost-effective ranges that won’t put too much pressure on your purse strings.

Reuse or Refurbish

If your budget is tight, consider refurbishing existing fixtures or reusing items like cabinets or mirrors with a fresh coat of paint or new hardware. You are likely to save a considerable amount of money compared to the average cost of a new bathroom starting from scratch. It is better for the environment too.

Plan Efficiently

Our final money-saving tip is to plan effectively and resist changes during the installation of your new bathroom. Changes to the original plan mid-project can incur additional costs from your supplier. If this isn’t your strong point, it’s fine.

Expert Insights: How To Avoid Costly Bathroom Renovation Mistakes

Avoiding mistakes when renovating your bathroom is crucial to ensuring your project stays within budget and meets your expectations. There are a number of key tools, techniques and strategies you can adopt to steer clear of costly bathroom renovation errors.

Firstly, inadequate planning can lead to oversights and unforeseen expenses. By taking the time to create a detailed plan that outlines the scope of the project, including design choices, materials, and a realistic budget you can avoid surprises. It is important to discuss this with any chosen supplier. They should be able to quote for any work accurately without the prospect of additional costs coming out of the woodwork. This planning phase is essential for avoiding costly changes or delays during the renovation process.

Another common mistake is underestimating the importance of professional help. While DIY projects can save money, complex tasks like plumbing and electrical work need skilled contractors and tradespeople. This may seem like an additional expense but working with skilled fitters and installers can prevent costly repairs or rework should things go wrong.

Choosing materials solely based on aesthetics is easy to do but best avoided. Investing in quality durable materials will save you money in the long run.

Lastly, succumbing to impulsive decisions during a bathroom renovation process can lead to regrets and additional expenses. Stick to your initial plan and avoid last-minute changes that can disrupt the workflow and strain your budget. By steering clear of these common mistakes, you can ensure a smoother, more cost-effective, and ultimately satisfying bathroom renovation experience.
