If your bathroom is looking a bit tired and dated, or even if you just fancy a bit of a revamp to breathe new life into your home, you might have asked yourself, “How much does a bathroom renovation cost?”. If you have, you’re not alone. In fact, bathroom renovations are one of the most common home improvement projects in the UK. However, the total cost can vary significantly, ranging from simple updates at the lower end of the scale to complete transformations that require a significant investment.

In this article, we are going to address this important question so that you can plan your budget accordingly. We will explore various factors that influence the cost of a bathroom renovation, including labour, materials, design complexity and any additional features like underfloor heating or high-end finishes.

Factors That Influence the Cost of a Bathroom Renovation

So, how much does a bathroom renovation cost and what factors influence the final price?

Unfortunately, there is no simple “one-size-fits-all” answer to this question, as costs can vary widely depending on the size of your bathroom, the quality of materials you will use and the extent of the changes you plan to make. Thankfully, though, whether you’re simply updating fixtures and fittings or planning to undertake a complete overhaul, the investment can significantly increase the comfort and value of your home. The key, as with any renovation, is doing your homework and calculating an accurate budget that takes into account all anticipated expenses before you start work. That way, there are no nasty surprises along the way. (After all, nobody wants to find themselves halfway through a renovation only to realise they are running out of funds.)

With this in mind, we are going to explore the key elements that you need to account for when you calculate your bathroom renovation budget.

Size and Layout of the Bathroom

The size and layout of your bathroom are fundamental factors that will directly impact the cost of your renovation. A larger space will obviously require more materials and potentially more complex plumbing and electrical work than a smaller bathroom, increasing the overall investment. Not only that, but if you plan on reconfiguring the layout you might need to conduct significant structural alterations, such as moving walls, relocating plumbing fixtures or adding new windows or doors. These changes can require additional permits and professional services, which add to the cost and complexity of the project.

Quality of Materials

Another important factor that will influence the cost of your bathroom renovation is the quality of materials that you plan to use. For instance, opting for high-end materials like marble tiles, quartz countertops or designer fixtures can significantly increase your budget compared to more affordable choices such as ceramic tiles and laminate surfaces. The key is finding a balance between cost and quality so that the final renovation aligns with both your budget and design preferences.

Structural Changes

If your bathroom renovation requires any structural changes, such as moving walls or changing the overall layout, then you need to account for these additional costs when you calculate your budget. Likely costs for these changes will include architect or structural engineer fees and potential expenses associated with permits and planning permission, if applicable. 

Plumbing and Electrical Work

Updating or relocating plumbing and electrical fixtures is a common part of many bathroom renovations. The extent of these changes can vary, but they often involve substantial work and expertise, leading to higher costs, especially if the property's existing systems are outdated or not up to current standards.

Labour Costs

The cost of labour is a major component of any bathroom renovation budget. Hiring experienced professionals ensures quality work, but it also represents a significant portion of the overall expense. The cost can vary depending on the area, complexity of the job and the expertise of the tradespeople.

Unforeseen Issues

Finally, make sure your bathroom renovation budget includes a contingency fund to cover those inevitable unforeseen issues. For instance, you might discover that your existing plumbing is outdated or doesn’t meet building regulations standards, or there could be hidden water damage or mould behind the walls once you open them up. These issues will usually require immediate attention, which can significantly increase the cost of your renovation. 

As a general rule of thumb, it’s a good idea to set aside an additional 10-20% of your total budget as a contingency fund. That way, you have the funds you need to tackle unexpected costs without compromising the quality or scope of your bathroom renovation.

Breaking Down the Costs

We’ve seen what factors can influence your total budget, but we still need an answer to the question, “How much does a bathroom renovation cost?”

Time to crunch some numbers! 

We are going to break down the average costs associated with each of the factors we have just explored. This should give you a ballpark figure to get you started with your budget. However, keep in mind that the figures we will be sharing are just estimates. Accurate costs will depend on the unique characteristics and requirements of your bathroom renovation, as well as your location and changes in market conditions.

Labour Costs

Labour constitutes a significant portion of the total cost of a bathroom renovation. In fact, it can potentially account for 40-50% of your total budget. For instance, in the UK, hiring skilled professionals like plumbers and electricians can range from £150 to £250 per day, depending on their expertise and the local area. For a complete bathroom renovation, labour costs can easily reach £2,000 to £3,000. It’s always a good idea to request multiple quotes to ensure the price you pay for labour is reasonable and competitive.

Materials and Fixtures

The cost for materials and fixtures can vary widely, from budget-friendly options at a few hundred pounds to luxury materials and high-end brands that can exceed £5,000. For example, basic tiles might cost £20 per square metre, while premium options could be £50 per square metre or more. Similarly, a standard bathroom suite can start around £500, with high-end models reaching £2,000 or higher.

Design and Planning

Professional design and planning services can range from £500 to £2,000 or more, depending on the project's complexity and the designer's reputation. However, this investment can help you optimise the design of your bathroom space, improve functionality and protect you from costly mistakes during the renovation process. Hiring a professional designer is particularly important if you are planning an extensive renovation or a complete overhaul of your bathroom's layout.

Structural Changes

Structural alterations, such as removing walls or changing the bathroom layout, typically start from £1,500 to £3,000. These expenses can escalate if you need to hire structural engineers or apply for planning permission. It’s a good idea to organise a professional assessment in advance to find out if these changes are both necessary and cost-effective.

Plumbing and Electrical Updates

Updating plumbing and electrical systems can cost between £800 and £1,500 for a standard bathroom renovation, with more extensive rewiring or replumbing reaching upwards of £2,000 to £3,000. These updates are essential for older homes to meet current safety standards and accommodate new fixtures. Make sure this type of work is carried out by certified professionals to ensure compliance with UK building regulations.

Finishing Touches

Finally, the finishing touches of your bathroom renovation like paint, lighting and accessories, can add approximately £500 to £1,000 to your budget. While individual items may seem inexpensive, the cumulative cost can become more significant. 

What’s more, integrating luxury features such as underfloor heating and high-end finishes like marble countertops or fancy taps can raise the cost of your bathroom renovation. However, while these upgrades cost more upfront, they may prove to be worth it for the extra comfort and style they bring.

Maximising Your Bathroom Renovation Budget

Finally, we want to share a few essential tips to help you maximise your bathroom renovation budget and build your dream space without overspending:

• Prioritise key upgrades. Focus on changes that will have the most significant impact on the look and functionality of your bathroom. 
• Reuse when possible. Consider which components of your current bathroom can be refurbished or reused. Items like vanities can often be repainted or updated with new hardware for a fresh look at a lower cost.
• Compare quotes. Get multiple quotes for labour and materials to ensure you're getting the best deal. Don't just look at the bottom line; consider the value and quality of what's being offered.
• Opt for mid-range materials. Choosing mid-range materials can provide the best balance between cost and quality. High-end materials may offer diminishing returns on investment, whereas the cheapest options might not last.
• DIY what you can. Evaluate which parts of the renovation you can realistically do yourself. For instance, tasks like painting or installing hardware can save on labour costs if you're confident in your abilities.
• Pick a reputable contractor. Finally, it's crucial to select a trustworthy and experienced contractor for your project. By choosing a reliable company like JM Construction, you can ensure that your bathroom renovation will be completed to the highest standards, within your budget and on schedule.
