Planning a new bathroom is exciting. Whether you’re dreaming of a luxurious wet room, a modern family bathroom or an accessible bathing space that will serve you for years to come, it’s often one of the most rewarding home improvements you can make.
One of the most common questions we hear from homeowners across Leicestershire is simple: where do you actually start?
Many people spend months choosing tiles, scrolling through bathroom inspiration on social media and collecting ideas from magazines, only to realise they aren’t entirely sure how the renovation process unfolds. Understanding the correct order of a bathroom renovation can help avoid costly mistakes, reduce stress and ensure the finished space looks exactly as you imagined.
At Casey Interiors, we’ve renovated bathrooms in period cottages, modern new-builds, family homes and listed properties. While every project is different, the process usually follows a similar sequence.
It All Starts With Understanding How You Use the Space
Before anyone lifts a tool or orders a single tile, the first step should always be understanding how the bathroom needs to function.
A beautiful bathroom that doesn’t work for your daily routine quickly becomes frustrating. A family with young children will have different requirements from a retired couple planning to age comfortably in their home. Likewise, a guest ensuite has very different demands compared to a busy family bathroom.
This early planning stage is where the biggest decisions are made. Layout changes, storage requirements, shower preferences and accessibility considerations should all be discussed before moving forward.
“One of the biggest mistakes homeowners make is focusing on products before they’ve thought about how the room needs to work,” says Dan Casey, founder of Casey Interiors. “The best bathrooms are designed around the people using them. Once we understand that, choosing the right products becomes much easier.”
Creating a Design That Balances Style and Practicality
Once the practical requirements are established, attention can turn to design.
This is where homeowners often begin exploring colours, materials, lighting schemes and overall style. Some clients arrive with a clear vision, while others need guidance to refine their ideas.
The goal isn’t simply to create a bathroom that looks good today. It should still feel stylish and functional years from now.
At Casey Interiors, we encourage clients to think beyond trends and focus on timeless design choices combined with quality materials that will stand the test of time.
Establishing a Realistic Budget
Before products are selected, it’s important to understand the available budget.
Bathroom renovations vary significantly in cost depending on the size of the room, the complexity of the work and the specification of fixtures and finishes.
A clear budget helps guide decisions throughout the project and allows realistic expectations to be established from the outset. It also provides an opportunity to identify where investment will deliver the greatest long-term value.
Many homeowners are surprised to learn that careful planning often saves more money than choosing cheaper products.
Finalising Measurements and Ordering Materials
Once the design has been agreed, precise measurements become essential.
Every tile, shower enclosure, vanity unit and piece of furniture needs to fit perfectly within the space. Ordering products before measurements are confirmed can create expensive delays and complications.
This stage also ensures all materials arrive before installation begins, helping to keep the project running smoothly.
Removing the Existing Bathroom
Only once the planning and ordering stages are complete should the existing bathroom be removed.
This demolition phase involves carefully disconnecting plumbing, removing sanitaryware, taking out old tiles and preparing the room for renovation.
Many homeowners underestimate how much preparation work is involved at this stage. Removing a bathroom often reveals hidden issues such as ageing pipework, water damage or uneven walls that need addressing before installation can begin.
First Fix Plumbing and Electrical Work
With the room stripped back, any necessary plumbing and electrical alterations can take place.
If a toilet is moving position, a new shower is being installed or additional lighting is being added, this is the stage where those changes happen.
Completing this work before surfaces are finished prevents unnecessary disruption later in the project.
Preparing Walls, Floors and Waterproofing
Before any tiles or wall coverings are installed, the room needs to be properly prepared.
This may involve plastering, levelling floors, installing backer boards and applying waterproofing systems. For wet rooms, this stage is particularly important as correct tanking and drainage installation are critical to long-term performance.
Although much of this work remains hidden behind finished surfaces, it forms the foundation of a successful bathroom renovation.
Tiling and Surface Finishes
With preparation complete, attention turns to the visible finishes.
Wall tiles, floor tiles, decorative panels and other surface treatments are installed before the main fixtures are fitted. This allows for a cleaner, more professional finish and ensures the room feels cohesive.
The choice of materials can dramatically influence the overall appearance of the bathroom, from contemporary spa-inspired spaces to traditional designs that complement period properties.
Installing Fixtures and Furniture
Once the walls and floors are complete, the bathroom begins to take shape.
Baths, showers, toilets, basins, vanity units and fitted furniture can now be installed. This is often the stage homeowners enjoy most, as the design starts becoming a reality.
Careful installation is essential to ensure everything functions correctly while maintaining the clean lines and finish expected from a high-quality bathroom renovation.
Lighting, Decoration and Final Details
The final stage focuses on the details that bring the room together.
Mirrors, lighting, heated towel rails, accessories and decorative finishes are installed. Every element is checked, tested and adjusted to ensure the bathroom performs exactly as intended.
These finishing touches may seem small, but they often have the biggest impact on how the room feels.
Why Planning Makes All the Difference
A successful bathroom renovation is rarely about a single product or design trend. It is the result of careful planning, skilled installation and attention to detail at every stage.
Following the correct order helps prevent delays, avoids unnecessary costs and ensures each element of the renovation supports the next.
At Casey Interiors, we guide homeowners through the entire process, from initial ideas and design concepts through to installation and finishing touches. Whether you’re planning a contemporary wet room, a luxury ensuite or a complete family bathroom renovation, our aim is always the same: to create a space that looks beautiful, functions perfectly and adds lasting value to your home.
Frequently Asked Questions
How long does a typical bathroom renovation take?
Most bathroom renovations take between two and four weeks, depending on the complexity of the project, the size of the room and whether structural alterations are required.
Should I choose my bathroom suite before planning the layout?
Not necessarily. The layout should be designed around how you use the space first, then products can be selected to complement the design.
When should tiles be installed during a bathroom renovation?
In most projects, wall and floor tiling is completed before the final installation of sanitaryware and furniture to achieve the best possible finish.
Can I stay in my home during a bathroom renovation?
In most cases, yes. However, if it’s your only bathroom, alternative arrangements may need to be considered during certain stages of the work.
Is it worth hiring a bathroom specialist?
A specialist can help avoid common mistakes, coordinate different trades, manage the project efficiently and ensure the finished bathroom meets both practical and aesthetic requirements.
