Bathroom Renovation Checklist: 9 Essential Steps for 2025

Embarking on a bathroom renovation is an exciting prospect, transforming a purely functional space into a personal sanctuary. However, the path from your initial vision to a flawless finished room is paved with crucial decisions and detailed planning. Without a structured approach, homeowners can face unexpected costs, frustrating delays, and a final result that doesn't quite meet their expectations. This is where a comprehensive bathroom renovation checklist becomes an indispensable tool, acting as your project blueprint from start to finish.

This guide is designed to demystify the renovation process for homeowners across Eastbourne and Sussex. We will break down the entire project into nine manageable, sequential steps. From establishing a realistic budget that accounts for local material and labour costs to planning a functional layout that maximises your space, we cover every critical stage. You will learn how to assess essential plumbing and electrical systems, choose appropriate waterproofing and ventilation to combat our coastal climate, and select durable fixtures that blend style with longevity.

Think of this checklist as your strategic partner, ensuring no detail is overlooked. It provides the actionable framework needed to avoid common pitfalls and make informed decisions. By following this structured plan, you can confidently manage your project, whether you're undertaking a DIY refresh or collaborating with professionals. For complex tasks like re-routing pipework or installing new heating systems, local experts like us at Harrlie Plumbing and Heating are always on hand to ensure the work is completed safely and to the highest standard, turning your checklist into a beautifully realised bathroom.

1. Establish a Realistic Budget: The Financial Foundation for Your Eastbourne Renovation

Before a single tile is chosen or a tap is ordered, the most critical step in your bathroom renovation checklist is establishing a detailed and realistic budget. This financial blueprint governs every subsequent decision, ensuring your project remains viable without causing unnecessary stress. A comprehensive budget extends far beyond the price of a new toilet and basin; it must meticulously account for every potential expense.

Breaking Down the Costs

Your budget should be itemised to provide a clear overview of where your money is going. Key categories to include are:

• Materials & Fixtures: This covers everything from tiles, flooring, and paint to the bath, shower, vanity unit, and taps. Researching costs at local Eastbourne suppliers versus online retailers can reveal significant savings.

• Labour: This is often the largest expense. A detailed quote, like those provided by Harrlie Plumbing and Heating, will break down the costs for plumbing, tiling, electrical work, plastering, and installation.

• Permits & Regulations: Depending on the scale of your renovation, you may need to factor in costs for planning permissions or building regulations approval from the Eastbourne Borough Council, especially if you are altering the property's structure.

• Contingency Fund: This is non-negotiable, particularly in the older properties common across East Sussex. We recommend setting aside 15-20% of your total budget for unexpected issues, such as discovering rotten joists or needing to re-plaster a wall after tile removal. A client in the Meads area recently allocated a £1,500 contingency, which perfectly covered this exact scenario, preventing a project delay.

The following chart illustrates typical budget ranges and the vital role of a contingency fund in UK bathroom renovations.

As the data shows, the financial gap between a basic and a luxury renovation is substantial, reinforcing why a well-planned contingency fund is essential to absorb unexpected costs at any budget level.

2. Plan the Layout and Space Optimization: Maximising Functionality in Your Eastbourne Home

Once your budget is set, the next crucial item on your bathroom renovation checklist is planning the layout. This stage is about more than just deciding where things go; it's a strategic process of optimising every square centimetre for functionality, flow, and comfort. A well-planned layout can transform a cramped, awkward space into an efficient and relaxing sanctuary, significantly impacting both the final cost and the daily usability of your new bathroom.

This step involves deciding whether to keep your existing plumbing layout or undertake a more complex reconfiguration. While keeping fixtures in their original positions is more budget-friendly, relocating a toilet or shower can unlock a room's full potential. For example, in many Eastbourne Victorian terraced houses, moving the toilet away from being the first thing you see when you open the door can dramatically improve the room's feel.

Breaking Down the Layout

Strategic space planning ensures your bathroom is not only beautiful but also practical and compliant with UK building regulations. Key considerations include:

• Fixture Placement: The location of your bath, shower, toilet, and vanity dictates the room's entire flow. Consider how you move around the space and ensure there is adequate clearance. UK standards generally require at least 60cm of clear space in front of a toilet and 76cm in front of a vanity to ensure comfortable use.

• Storage Solutions: A common complaint is lack of storage. Planning your layout allows you to integrate solutions like recessed shelving, vanity units with deep drawers, or tall cabinets. For a recent project in a Polegate townhouse, we at Harrlie Plumbing and Heating installed a wall-mounted vanity and toilet, creating an illusion of more floor space and simplifying cleaning.

• Accessibility & Future-Proofing: Consider 'aging-in-place' principles. A layout featuring a curbless, walk-in shower or ensuring doorways are wide enough for potential mobility aids can add long-term value and practicality to your home, a popular request for bungalows in the Langney area of Eastbourne.

• Ventilation and Lighting: The layout phase is the ideal time to plan for an efficient extractor fan and a layered lighting scheme. Positioning these elements correctly is vital for preventing damp and creating the right atmosphere.

The video below offers excellent visual tips for planning your bathroom layout effectively.

To get started, use painter's tape on the floor to mock up the footprint of new fixtures. This simple trick helps you visualise the space and identify potential issues with traffic flow before any plumbing work begins.

3. Assess and Upgrade Plumbing and Electrical Systems: The Hidden Essentials

Behind the gleaming tiles and stylish fixtures lies the critical infrastructure of your bathroom: the plumbing and electrical systems. Overlooking these hidden essentials during a renovation is a common but costly mistake. Assessing and upgrading these systems before any cosmetic work begins is a non-negotiable part of any comprehensive bathroom renovation checklist, ensuring safety, functionality, and long-term peace of mind.

Breaking Down the Assessment

A thorough evaluation of your existing infrastructure is essential, particularly in the characterful older properties found throughout Eastbourne and East Sussex. Key areas for inspection include:

• Plumbing Infrastructure: This covers pipe condition, water pressure, and drainage efficiency. Older homes may have outdated materials like lead or galvanised steel pipes that are prone to corrosion and leaks. A professional assessment by a qualified plumber, like our team at Harrlie Plumbing and Heating, can determine if a partial or complete repipe to modern copper or PEX is necessary.

• Electrical Systems: Modern bathrooms have greater electrical demands than ever before. Your existing wiring must be able to safely handle features like illuminated mirrors, electric showers, and underfloor heating. This includes verifying the capacity of your consumer unit and ensuring all sockets and circuits comply with current UK safety regulations (BS 7671).

• Safety Compliance: Modern building regulations require specific safety measures, such as RCD (Residual Current Device) protection for all bathroom circuits to prevent electric shock. An electrician must verify that your system is up to code. For example, a recent project in the Old Town area of Eastbourne required a dedicated new circuit for a high-powered digital shower, an upgrade the original 1960s wiring could not support.

• Ventilation: Proper ventilation is crucial for preventing damp and mould. The assessment should include checking the effectiveness of any existing extractor fan and determining if an upgrade is needed to meet the demands of a new shower or bath configuration.

A professional evaluation, like those conducted by the Harrlie Plumbing and Heating team, ensures these foundational elements are sound before you invest in the visible finishes. Many older homes present unique challenges, and understanding them is key; you can explore our guide on common plumbing issues in older Eastbourne properties to learn more.

4. Choose Appropriate Waterproofing and Ventilation: Protecting Your Home from Moisture

Beyond the visible aesthetics of tiles and taps lies a crucial, unseen element of any bathroom renovation checklist: moisture management. Proper waterproofing and ventilation are non-negotiable foundations for a durable, healthy bathroom, preventing costly issues like mould, mildew, and structural rot that thrive in damp environments common in coastal towns like Eastbourne.

Breaking Down Moisture Management

A successful moisture strategy involves two key components: a robust waterproof barrier in wet areas and an effective mechanical ventilation system to remove humid air.

• Waterproofing Systems: Modern bathrooms require more than just water-resistant tile backer boards. A complete waterproofing membrane system creates a fully sealed "tanked" area within your shower or around your bath. This involves applying waterproof membranes, sealing bands over all joints and corners, and ensuring proper drainage slopes are created. This is a standard practice for all wet room installations completed by Harrlie Plumbing and Heating.

• Mechanical Ventilation: An extractor fan is essential for actively removing steam and moisture. The fan's power is measured in cubic feet per minute (CFM), and a good rule of thumb is to have at least 1 CFM per square foot of bathroom space. For a typical Eastbourne bathroom, a fan rated at 50-80 CFM is often sufficient. It is a legal requirement for the fan to vent directly outside, never into an attic or loft space where it can cause damp.

• Installation Standards: The Tile Association (TTA) in the UK provides detailed standards for creating waterproof and long-lasting tiled environments. We at Harrlie Plumbing and Heating ensure our installations adhere to these best practices, giving you peace of mind that your investment is protected. For instance, a recent project in the Sovereign Harbour area involved installing a high-capacity 110 CFM fan with a humidity sensor, which automatically activates to combat the high moisture levels from a large walk-in shower. This proactive approach prevents moisture build-up before it can become a problem.

Getting these technical details right is paramount. Investing in professional installation for your waterproofing and ventilation systems is a critical step to safeguard your home and ensure your newly renovated bathroom remains beautiful and functional for years to come.

5. Select Durable and Appropriate Flooring: The Groundwork for Safety and Style

The flooring is the foundation of your bathroom's design and functionality. It must endure high moisture levels, temperature swings, and daily foot traffic while ensuring safety and complementing the overall aesthetic. Choosing the right material is a crucial step in any bathroom renovation checklist, as it profoundly impacts both the long-term durability and the day-to-day comfort of your new space.

Bathroom flooring is not just a style choice; it's a technical one. The material must be waterproof or highly water-resistant to prevent damage to the subfloor and the structure of your home. Key considerations include slip resistance, ease of cleaning, and compatibility with underfloor heating systems, which are increasingly popular in Eastbourne homes for that touch of everyday luxury.

Breaking Down Flooring Options

Your choice of flooring will influence both your budget and maintenance routine. Here are some of the most suitable options for a bathroom environment:

• Porcelain or Ceramic Tiles: A classic and extremely durable choice. We recommend porcelain over ceramic as it is denser and less porous, offering superior water resistance. Using larger format tiles (e.g., 600x600mm or larger) can create a more spacious feel and minimise grout lines, simplifying cleaning.

• Luxury Vinyl Tile (LVT): An excellent and often more affordable alternative. High-quality LVT realistically mimics the look of natural stone or wood but is fully waterproof, warmer underfoot, and easier to install. A recent project we completed in Sovereign Harbour used LVT to achieve a stunning marble effect at a fraction of the cost and installation time.

• Underfloor Heating: This is a speciality for Harrlie Plumbing and Heating. Installing an electric underfloor heating mat before the tiles are laid adds a significant layer of comfort, especially during colder East Sussex months. It's a relatively affordable luxury when installed as part of a full renovation.

• Safety & Finish: Regardless of material, prioritise safety. Opt for tiles with a textured or matte finish to provide better grip. Look for a suitable slip-resistance rating (an R-rating of R10 or higher is ideal for wet areas) to ensure the floor is safe, a critical factor for families and older individuals.

6. Install Quality Fixtures and Hardware

The fixtures and hardware are the high-touch, functional centrepieces of your bathroom, and selecting quality items is a crucial step in any successful bathroom renovation checklist. These elements, including the toilet, basin, taps, shower system, and even door handles, directly impact daily usability, water efficiency, and the room's overall aesthetic cohesion. Investing in well-made products ensures longevity and a superior user experience.

Breaking Down Fixture Selection

Choosing the right fixtures involves balancing style, function, and budget, which typically accounts for 15-20% of the total renovation cost. Modern options offer significant benefits beyond looks.

• Toilets & Basins: Look for models with high-efficiency flushes to conserve water. For instance, we recently installed a sleek, wall-hung toilet for a client in Sovereign Harbour, which not only saved space but also reduced their water usage.

• Taps & Shower Systems: Reputable brands like Grohe, Hansgrohe, and Bristan offer thermostatic shower valves that prevent scalding, a key safety feature. Pressure-balance valves, a standard in all Harrlie Plumbing and Heating installations, provide a consistent and comfortable showering experience.

• Hardware & Accessories: Cohesion is key. Ensure that all metal finishes, from the tap and showerhead to the towel rail and toilet roll holder, are perfectly matched. This small detail creates a high-end, professionally designed look.

• Privacy and Security: An often-overlooked detail is the door hardware. Choosing the right lock is essential for ensuring privacy. For detailed information on different options, consult this resource: A Homeowner's Guide to Bathroom Door Lock Types.

When making your selections, always prioritise established brands known for good warranty coverage and reliable performance. Our team can advise on the best fixtures to suit your specific needs and budget, ensuring every component we install is built to last and functions flawlessly.

7. Plan Adequate Storage and Organisation

A beautiful bathroom quickly loses its appeal if cluttered with toiletries, towels, and cleaning supplies. That's why planning for adequate storage is a non-negotiable step in your bathroom renovation checklist. Effective organisation maximises functionality and creates a serene, spa-like atmosphere, which is essential whether you have a compact en-suite in Sovereign Harbour or a large family bathroom in Old Town.

Breaking Down Storage Solutions

A well-thought-out storage strategy integrates different solutions to meet your household's specific needs, aiming to increase usable space by as much as 30-40%. Key options to consider are:

• Vanity Units: Modern vanity units offer deep drawers and clever internal dividers. Floating vanities create an illusion of space, while traditional floor-standing units provide maximum capacity.

• Recessed Shelving: Making use of the space between wall studs is a genius space-saving tactic. Recessed shower niches keep shampoos and soaps tidy, while a mirrored, recessed medicine cabinet above the basin offers discreet storage without protruding into the room. This is a particularly effective solution we often implement in the smaller bathrooms found in Eastbourne's Victorian properties.

• Vertical Storage: In smaller Eastbourne bathrooms where floor space is at a premium, think vertically. Tall, narrow cabinets or ladder-style shelving can store towels and decorative items without overwhelming the space.

• Creative Solutions: Don't overlook hidden opportunities. We often recommend toe-kick drawers beneath vanity units for stashing cleaning supplies or a set of scales. For a touch of luxury, one client in Meads opted for a custom unit that included a heated towel store and an integrated laundry hamper.

At Harrlie Plumbing and Heating, our installation process includes advising on the best storage configurations for your layout. We ensure that every cabinet is perfectly fitted and every niche is expertly tiled, transforming your design into a practical, organised reality. A proactive approach to storage ensures your new bathroom remains a functional and clutter-free sanctuary for years to come.

8. Choose Appropriate Lighting Design

Proper lighting is a transformative element in any bathroom renovation, capable of turning a purely functional space into a serene and inviting retreat. Overlooking the lighting plan is a common misstep in a bathroom renovation checklist; a well-thought-out design involves a layered approach that balances general illumination with specific, task-oriented lighting to create both ambiance and practicality. This strategic layering ensures your Eastbourne bathroom is perfectly lit for every activity, from a quick morning routine to a relaxing evening soak.

Breaking Down the Layers

An effective lighting plan integrates multiple sources to achieve a balanced and versatile environment. Key layers to consider are:

• Ambient Lighting: This is the main source of light, providing overall illumination. Recessed ceiling downlights or a central flush-mount fixture are popular choices for creating a bright, even base layer.

• Task Lighting: Crucial for grooming activities like applying makeup or shaving, task lighting eliminates shadows around the vanity area. We often install vertical sconces on either side of the mirror at eye level (around 1.5-1.7m from the floor) for our clients in the Old Town area of Eastbourne, ensuring flattering, shadow-free light.

• Accent Lighting: This layer adds depth and highlights architectural features or decorative elements. A well-placed spotlight on textured tiles or a recessed LED strip within a shower niche can create a stunning focal point. A recent luxury renovation we completed in Sovereign Harbour featured a backlit mirror and subtle niche lighting, adding a high-end, hotel-like feel.

• Smart & Efficient Technology: Modern LED technology offers significant advantages, using up to 75% less energy than traditional incandescent bulbs. We recommend bulbs with a Colour Rendering Index (CRI) of 90+ for true-to-life colour accuracy. Installing dimmer switches, a service Harrlie Plumbing and Heating regularly provides, offers ultimate control, allowing you to adjust the mood from bright and energising (around 4000K) to warm and relaxing (closer to 2700K). Always ensure all fixtures are correctly IP-rated for damp or wet zones for safety.

9. Obtain Necessary Permits and Ensure Code Compliance

One of the most frequently overlooked steps in a bathroom renovation checklist is navigating the world of permits and building regulations. This administrative step is crucial for ensuring your project is safe, legal, and won't cause complications later on. A properly permitted renovation guarantees that all plumbing, electrical, and structural work adheres to national standards and the specific requirements set by the Eastbourne Borough Council.

Breaking Down Compliance Requirements

Failing to secure the right permissions can lead to significant fines, difficulties when selling your property, and even orders to undo completed work. It’s essential to understand what your renovation entails.

• When Permits are Needed: Major changes almost always require approval. This includes moving waste pipes, altering the property's structure (like removing a wall), or installing new electrical circuits. Minor cosmetic updates, such as painting or replacing a like-for-like tap, typically do not.

• Code Compliance: Building Regulations in the UK set standards for ventilation (Part F), electrical safety in wet areas (Part P), and drainage (Part H). For instance, any new electrical work must be carried out and certified by a competent person.

• The Role of Your Contractor: An experienced team, like Harrlie Plumbing and Heating, will manage this entire process. We understand the local Eastbourne requirements and handle the application and communication with council inspectors, ensuring every aspect of the job is compliant. This removes a significant burden from you, the homeowner.

• Avoiding Future Problems: A recent home sale in the Sovereign Harbour area was delayed by two months because the previous owner’s bathroom renovation lacked the proper electrical installation certificate. The new buyers’ solicitor flagged the issue, forcing costly and intrusive remedial work before the sale could proceed. This scenario highlights the long-term value of ensuring full compliance from the outset.
