Bathroom Renovation Order of Work: A Complete Step-by-Step Guide

Renovating a bathroom is one of the most effective ways to improve your home, enhance everyday comfort and create a space that better suits your lifestyle. However, knowing where to start can often feel overwhelming. From deciding on a layout and setting a budget to choosing products and coordinating trades, there are many moving parts involved in a successful renovation.

Understanding the correct bathroom renovation order of work can make the process far more manageable. By following a structured approach, you can avoid unnecessary delays, reduce the risk of costly mistakes and ensure each stage of the project is completed in the right sequence.

Whether you're planning a simple bathroom refresh, replacing an existing suite or undertaking a complete redesign, every successful renovation follows a similar journey. It starts with understanding your requirements, moves through budgeting and design, before progressing into removal, installation and finishing touches.

At More Bathrooms, our fully project-managed service takes care of this process on your behalf, coordinating every stage from initial design through to final installation. However, even if you're still researching your options, understanding the process will help you make more informed decisions and approach your project with confidence.

In this guide, we'll explain the complete bathroom renovation order of work, answer some of the most common questions homeowners ask and provide helpful resources to support your planning.

What is a Bathroom Renovation Order of Work?

A bathroom renovation order of work is the structured sequence of tasks required to transform your existing bathroom into a new space. Each stage depends on the one before it, meaning the project must be completed in the correct order to ensure everything runs smoothly.

For example, plumbing and electrical work must be completed before wall coverings are installed, while sanitaryware cannot be fitted until walls and floors have been finished. If tasks are completed out of sequence, delays, additional costs and unnecessary rework can quickly arise.

A typical bathroom renovation may involve plumbers, electricians, tilers, flooring specialists and installers, all working at different stages of the project. When managed correctly, each trade arrives at the right time, materials are available when needed and the project progresses efficiently.

A clear order of work helps ensure:

> Better project planning
> Improved budget control
> Fewer delays
> Reduced disruption
> Higher quality installation standards
> A smoother renovation experience

While every project is unique, the core principles remain largely the same. The five key stages of a bathroom renovation are:

> Assessing your requirements
> Setting a realistic budget
> Choosing your design and specification
> Removing your old bathroom
> Installing your new bathroom

Step 1: Assessing Your Bathroom Requirements

Every successful bathroom renovation starts with understanding exactly what you need from the space.

Before looking at colours, tiles or bathroom suites, take the time to assess how your existing bathroom functions and identify what you would like to improve. This stage lays the foundations for the entire project and can help prevent costly changes later.

Start by considering how the room is currently used. Ask yourself:

> Is there enough storage?
> Does the layout work effectively?
> Do you use the bath regularly?
> Is the shower large enough?
> Does the room feel cluttered?
> Are there any accessibility concerns?
> Is the space suitable for your future needs?

Many homeowners find their priorities have changed since the bathroom was originally installed. A growing family may require additional storage and practicality, while others may be looking to create a more luxurious space for relaxation or future-proof the room to support changing mobility requirements.

It's equally important to consider the physical limitations of the space. Room dimensions, door positions, windows, soil stacks and existing plumbing locations can all influence what is achievable.

If you're considering a significant layout change, our guide on How To Plan Your Bathroom Layoutprovides useful advice on creating a practical and efficient bathroom design.

Similarly, one common decision homeowners face is whether to retain a bath or replace it with a shower. If you rarely use your bath, replacing it with a walk-in shower could improve accessibility, create a greater sense of space and better suit your day-to-day lifestyle.

If you're exploring this option, our guide to Walk-In Shower Dimensions explains the space requirements involved, while our range of Walk-In Showers provides inspiration for different styles and layouts.

At this stage, it can also be helpful to create a list of essential requirements and desirable features. Having a clear understanding of your priorities will help guide the design process and ensure your investment is focused on the features that matter most.

Step 2: Setting a Realistic Budget

Once you've identified your requirements, the next step is establishing a realistic budget.

Many homeowners initially focus on the visible elements of a renovation such as the bath, shower, furniture and tiles. However, a bathroom renovation budget should account for much more than the products themselves.

Typical costs can include:

> Sanitaryware
> Bathroom furniture
> Wall and Floor coverings
> Lighting
> Heating and Ventilation
> Plumbing and Electrical work
> Installation labour
> Waste removal
> Finishing touches and decorative elements

The overall cost will depend on the size of the room, the complexity of the design and the specification of products selected. A straightforward replacement of an existing suite will generally cost less than a complete redesign involving layout changes, extensive tiling and upgraded plumbing or electrics.

It's also sensible to allow some flexibility within your budget. Once the old bathroom has been removed, hidden issues such as damaged flooring, ageing pipework or signs of damp may become apparent and require attention before installation can continue.

Many homeowners also view their bathroom renovation as a long-term investment. Our guide on How Much Value Does a Bathroom Renovation Add? explores the potential impact a well-designed bathroom can have on your property.

Once you've established a realistic budget, the next stage is transforming your ideas into a fully developed design.

Step 3: Choosing Your Design and Specification

With your requirements established and budget in place, it's time to bring your vision to life.

This stage is often the most exciting part of the renovation process, as it involves selecting the products, finishes and design features that will shape the look and feel of your new bathroom. However, it's also one of the most important stages to get right. Finalising your specification before installation begins helps avoid delays, ensures products are available when required and reduces the risk of costly changes once work is underway.

A well-designed bathroom should balance practicality, aesthetics and budget. While it's easy to focus solely on appearance, the most successful bathrooms are those that work seamlessly for everyday life while still delivering the style and atmosphere you're looking for.

When planning your design, there are six key areas to consider:

> Colour scheme
> Sanitaryware
> Wall and floor coverings
> Lighting
> Fitted furniture and storage
> Heating and ventilation

Colour Scheme

Your colour palette will play a significant role in shaping the overall feel of the room.

Lighter shades such as white, cream and soft grey remain popular because they help smaller bathrooms feel brighter and more spacious. Darker tones can create a more dramatic and luxurious appearance, particularly when paired with contrasting brassware or feature finishes.

While trends can provide inspiration, it's worth remembering that a bathroom is a long-term investment. Choosing colours that you'll be happy living with for years to come is often more important than following the latest fashions.

If you're unsure which colours may work best within your space, our Bathroom Colour Guide explores popular colour schemes and offers inspiration for creating a bathroom that reflects your personal style.

Sanitaryware

Sanitaryware forms the foundation of your bathroom design and typically represents one of the largest areas of investment.

Your choices may include:

> Baths
> Walk-in showers
> Shower enclosures
> WCs
> Basins
> Vanity units
> Taps and brassware

When selecting products, it's important to consider both appearance and practicality. The size of the room, available space and how the bathroom is used should all influence your decisions.

This is one reason we always recommend visiting a showroom wherever possible. Seeing products in person allows you to assess their quality, scale and finishes far more effectively than browsing online alone.

Wall and Floor Coverings

Wall and floor coverings have a significant impact on both the appearance and practicality of your bathroom. Popular options include tiles, wall boards and vinyl flooring, each offering different aesthetic, maintenance and budget considerations.

If you're comparing different approaches, our guide to Half Tiled vs Full Tiled Bathroom Designsexplores the benefits of each option. You may also find our article on Tips for Choosing Bathroom Tiles useful when selecting colours, sizes and finishes.

Lighting

Lighting plays a major role in both the functionality and atmosphere of a bathroom. Most successful schemes combine practical task lighting around mirrors with ambient lighting that creates a comfortable overall feel.

The right lighting solution will depend on the size of the room, the amount of natural light available and how the space is used.

For further inspiration, read our guide to Bathroom Lighting Ideas or browse our range of Bathroom Lighting.

Fitted Furniture and Storage

Effective storage helps keep bathroom surfaces clear and allows everyday essentials to be organised neatly. Popular options include vanity units, mirror cabinets, recessed niches and fitted furniture.

The right solution will depend on the size of your bathroom, the number of people using it and the amount of storage required.

For ideas and inspiration, read our guide to Bathroom Storage Ideas or explore our range of Bathroom Storage.

Heating and Ventilation

Heating and ventilation are essential for creating a comfortable bathroom environment and helping to manage moisture levels.

Popular heating solutions include heated towel rails, designer radiators and underfloor heating, while effective ventilation helps reduce condensation and protect finishes over time.

Bringing Everything Together

By this stage, you should have a clear understanding of how your new bathroom will look, function and feel.

This planning work is essential because it allows products to be ordered, trades to be scheduled and installation work to be planned efficiently.

At More Bathrooms, our experienced designers help homeowners balance style, practicality and budget while creating a bathroom tailored to their individual needs. Once your design and specification have been finalised, the next step is preparing the room for transformation by removing the existing bathroom.

Step 4: Removal of Your Old Bathroom

Once your design has been finalised, products have been selected and the installation date has been agreed, the practical renovation work can begin.

The first on-site stage is usually the removal of your existing bathroom. This is often referred to as the strip-out stage and involves carefully removing the old suite, furniture, wall coverings and floor coverings so the room can be prepared for installation.

For a standard bathroom, strip-out will usually take around one day, although this can vary depending on the size of the room, the materials being removed and the condition of the existing installation.

During this stage, the installer will typically remove:

> Existing bath, shower, toilet and basin
> Old bathroom furniture
> Wall tiles, boards or other coverings
> Floor coverings
> Redundant fittings and accessories

Protective coverings should be used in the home before work begins, particularly along the route from the entrance to the bathroom. This helps protect flooring, carpets and surrounding areas while materials are being removed and waste is taken out.

This stage is not simply about clearing the room. It is also an important inspection point. Once the old bathroom has been removed, the installer can assess the condition of the underlying walls, floor, pipework and previous workmanship.

Hidden issues may include damaged floorboards, uneven walls, old pipework, signs of damp, previous leaks or poorly completed earlier installation work. These discoveries do not necessarily mean there is a major problem, but they may affect the rest of the project.

For example, damaged flooring may need to be replaced before new floor coverings can be laid, while damp or rotten timber may need to be addressed before new sanitaryware is installed.

This is one of the reasons a little flexibility within the project plan and budget is sensible. A careful strip-out helps identify and resolve issues properly rather than covering over problems that could become more expensive later.

At More Bathrooms, waste removal and site protection are handled as part of the managed renovation process. This helps reduce disruption and ensures the room is properly prepared before installation begins.

Step 5: Bathroom Installation – The Correct Order of Trades

The installation stage is the most technical part of the bathroom renovation process. It is also where the correct order of work matters most.

By this stage, the room has been stripped out, the design has been agreed and all key products and materials should be ready. The focus now shifts to coordinating the various trades and completing each stage in the correct sequence.

A bathroom installation typically involves plumbing, electrical work, waterproofing, wall coverings, flooring, sanitaryware fitting and finishing touches. Each stage must happen in the right order because later work often depends on earlier preparation.

The exact sequence can vary slightly depending on the bathroom layout, product choices and whether any significant changes are being made. However, the typical installation order is as follows.

1. First Fix Plumbing and Electrics

The first fix stage involves preparing the hidden plumbing and electrical work before walls, floors and finishes are completed.

This may include routing new pipework, adjusting waste connections, preparing shower supplies, relocating radiators, positioning lighting cables and installing wiring for extractor fans, mirrors or shaver sockets.

This stage must happen early because these elements are usually concealed behind walls, under floors or within furniture once the bathroom is complete.

If the layout is changing, first fix work becomes even more important. Moving a toilet, shower, basin or bath may require pipework and waste routes to be altered before any surface finishes can be installed.

The same applies to electrics. Bathroom lighting, ventilation and powered mirrors all need to be planned and safely installed in accordance with bathroom electrical regulations.

Completing this stage correctly ensures the room is ready for the next phase of preparation.

2. Waterproofing and Substrate Preparation

Once first fix plumbing and electrics have been completed, the walls and floors must be prepared for the chosen finishes.

This stage may involve repairing walls, levelling surfaces, replacing damaged boards, preparing floors and applying waterproofing systems in wet areas.

Waterproofing is particularly important around showers, baths and wet zones. In many projects, this process is known as tanking. It helps protect the structure of the room by preventing water from penetrating behind tiles or wall coverings.

Good substrate preparation is essential because wall and floor finishes can only perform properly when installed onto a suitable surface. If walls are uneven or floors are unstable, the finished result may be compromised.

This stage is often overlooked by homeowners because much of the work becomes hidden once the bathroom is complete. However, it plays a major role in the long-term durability of the renovation.

3. Wall Coverings

Once the room has been prepared, wall coverings can be installed which may involve fitting bathroom tiles, wall boards or a combination of both, depending on the agreed design.

Wall coverings are usually installed before floor coverings because it allows installers to achieve a cleaner finish and protects new flooring from unnecessary damage during wall installation.

If tiles are being used, this stage includes setting out tile positions, cutting around fixtures and ensuring grout lines are neat and consistent.

If wall boards are being fitted, panels are measured, cut and secured into position, often creating a smoother, lower-maintenance finish with fewer joints than traditional tiling.

The chosen wall covering has a major impact on both appearance and practicality, which is why these decisions should be confirmed during the design stage rather than once installation is underway.

4. Floor Coverings

After the wall coverings have been installed, the floor can usually be completed.

Common bathroom floor finishes include floor tiles and vinyl flooring. The right option will depend on your design preferences, budget and practical requirements.

Floor preparation is particularly important because bathrooms are high-moisture environments. The surface must be suitable, stable and level before the final floor covering is installed. Fitting flooring at this stage helps create a neat transition between wall finishes, sanitaryware and furniture.

5. Sanitaryware and Furniture Installation

Once the walls and floors are complete, the main bathroom products can be installed.

This includes items such as:

> Bath
> Shower enclosure or screen
> Toilet
> Basin
> Vanity unit
> Fitted furniture
> Storage units
> Heated towel rail or radiator

Installing sanitaryware after the wall and floor finishes helps protect the final surfaces and ensures the products sit neatly within the completed room.

This is also the stage where the bathroom begins to visibly take shape. The design choices made earlier in the process come together, and the room starts to feel like a finished space rather than a construction project.

Accurate fitting is important. Poorly aligned furniture, uneven sanitaryware or incorrect positioning can affect both appearance and usability.

6. Second Fix Plumbing and Electrics

Once sanitaryware and furniture have been installed, second fix plumbing and electrical work can take place.

This includes connecting taps, shower valves, wastes, toilets, lighting, extractor fans, shaver sockets, mirrors and any other electrical features included in the design. At this stage, the installer and relevant trades check that the bathroom is functioning correctly, which may include testing:

> Water supply
> Waste drainage
> Shower operation
> Tap pressure
> Toilet flushing
> Lighting
> Extractor fan performance
> Heated towel rails or radiators

Second fix is an important quality-control stage because it confirms that the main functional elements of the bathroom are operating as expected before the final finishing work is completed.

7. Finishing Touches

The final stage involves completing the finishing details that bring the bathroom together.

This may include:

> Mirrors
> Accessories
> Shelving
> Towel rails
> Toilet roll holders
> Silicone sealing
> Final cleaning
> Snagging checks

Although these details may seem small, they have a significant impact on the overall finish of the room.

Silicone sealing is particularly important in wet areas, helping protect joints around baths, showers, basins and flooring. Poor sealing can allow water to penetrate behind surfaces, so this stage must be completed carefully.

Snagging is also an important part of the process. This involves checking the completed bathroom for any small issues that need correcting before final handover.

At More Bathrooms, the installation process is managed from start to finish, helping ensure trades are coordinated, work is completed in the correct order and the final result meets the agreed specification.

The exact order may vary slightly depending on the complexity of the renovation, but following this structured sequence helps ensure the finished bathroom is practical, durable and completed to a high standard.

How Long Does a Bathroom Renovation Take?

One of the most common questions homeowners ask is how long a bathroom renovation will take.

While every project is different, a standard bathroom renovation typically takes around two weeks to complete. However, the exact timescale will depend on the size of the room, the complexity of the design and the amount of work involved.

For example, a straightforward like-for-like replacement where the existing layout remains unchanged will usually take less time than a complete redesign involving relocated plumbing, bespoke furniture, extensive tiling or structural alterations.

Several factors can influence the installation programme, including:

> Bathroom size
> Layout changes
> Plumbing alterations
> Electrical upgrades
> Extent of tiling
> Product lead times
> Bespoke furniture
> Drying times for adhesives and grout
> Any unforeseen issues discovered during strip-out

One advantage of a professionally managed renovation is that the installation schedule is coordinated from the outset. Trades are booked in advance, materials are ordered ahead of time and each stage is planned to minimise delays.

How Much Does a Bathroom Renovation Cost?

Cost is one of the most important considerations when planning a bathroom renovation. However, because every project is different, costs can vary significantly depending on the size of the room, the extent of any layout changes, product specification and installation requirements.

As a broad guide, a professionally installed bathroom renovation can range from around £8,000 to £25,000+, with most projects falling somewhere between these figures depending on the design, products selected and scope of work involved.

While many homeowners initially focus on the cost of the bathroom suite itself, it's important to remember that installation, plumbing, electrics, wall coverings, flooring and finishing touches all contribute to the overall investment.
