Choosing the right scope
What Type of Bathroom Project Are You Planning?
Some bathrooms need a straightforward replacement, while others require changes to the layout, plumbing, surfaces and room preparation. Defining the project correctly helps us plan the work, coordinate the trades and prepare a clearer quotation.
Bathroom Replacement
Suitable when the existing layout and main service positions can remain largely unchanged. The old fittings are removed and replaced without extensively reconfiguring the room.
- Existing layout largely retained
- Replacement bathroom suite and finishes
- Customer-supplied products can be fitted
Complete Bathroom Renovation
A coordinated refurbishment of the entire room, including strip-out, preparation and the connected installation work needed to produce a properly finished bathroom.
- Room preparation and damaged-surface repairs
- Plumbing, electrical and ventilation coordination
- Waterproofing, tiling, installation and decoration
Shower Room or Wet-Room Transformation
For bathrooms being adapted around a walk-in shower, more accessible arrangement or wet-room-style finish. These projects need careful planning of drainage, falls and waterproofing.
- Bath-to-shower transformations
- Walk-in shower and wet-room layouts
- Practical access and everyday-use planning
During a free site visit, we can inspect the existing bathroom, discuss the layout and products, and identify whether the project is a straightforward replacement or a more complete renovation.
One coordinated service
What Can Be Included in a Complete Bathroom Renovation?
A complete renovation brings the connected building and installation work into one agreed scope. The exact work depends on the existing room, the selected products and whether the bathroom layout will change.
Strip-Out and Preparation
Removal of the existing bathroom suite, finishes and agreed fittings, followed by preparation of the room. This may include repairing walls, floors or damaged backgrounds before the new installation begins.
Plumbing and Drainage
Plumbing can be prepared for the bath, shower, basin, toilet and other agreed fittings. Existing service positions may be retained or adjusted where the layout and property conditions allow.
Electrical Work and Ventilation
The agreed scope may include bathroom lighting, extractor ventilation, heated towel rails, electric underfloor heating and suitable electrical connections, subject to inspection and applicable safety requirements.
Waterproofing and Tiling
Wet areas can be prepared and waterproofed before wall and floor finishes are installed. The required method depends on whether the room includes a bath, enclosed shower, walk-in shower or wet-room arrangement.
Sanitaryware, Shower and Bath Installation
Installation can include the toilet, basin, bath, shower enclosure, shower controls, taps and related fittings specified in the quotation. Growchance or the customer may supply the products, depending on the agreement.
Furniture, Flooring and Final Finishes
The finishing scope may include vanity units, bathroom storage, mirrors, accessories, suitable flooring, sealing and decoration, creating a completed and practical room rather than an installation left unfinished.
The quotation will identify the work included, the products or allowances being supplied and any known exclusions. If hidden defects are discovered after strip-out, we will explain the issue and agree any additional work before proceeding.
Plan before installation
Planning Your Bathroom Layout and Products
A successful bathroom renovation starts with practical decisions about the layout, plumbing positions, everyday use and selected products. Growchance can help you review these details before the final scope and quotation are agreed.
Existing or Revised Layout
Keeping the main bathroom fittings in similar positions can simplify the work. Moving a toilet, basin, bath or shower may require additional plumbing, drainage and floor or wall preparation.
Bath, Shower or Both
The available space and the way your household uses the room will help determine whether the design should include a bath, enclosed shower, walk-in shower or a combination of fittings.
Storage and Daily Use
Vanity units, wall cabinets, shelving, mirrors and towel storage should be considered early. Their dimensions can affect clearances, electrical positions and the usable space around other fittings.
Tiles, Flooring and Finishes
Tile dimensions, wall coverage, flooring and decorative finishes affect preparation and installation. Product quantities and suitable background preparation should be established before work begins.
Lighting and Ventilation
Lighting, mirrors, electrical fittings and extractor ventilation should be planned together. The arrangement must reflect the room, existing services and appropriate bathroom safety requirements.
Access and Future Needs
Door movement, shower access, floor levels and space around the sanitaryware all affect how comfortable the bathroom will be to use. Future household needs can also be considered during planning.
During your free site visit, we can review the existing bathroom, discuss possible layouts and help identify the information and product choices needed before preparing the final scope.
Planning work in shared properties
Bathroom Renovation in London Flats and Shared Buildings
Renovating a bathroom in a flat often involves more than working inside the room itself. Access, water isolation, communal areas, building rules and neighbouring properties may all need to be considered before the installation begins.
Leasehold and Freeholder Requirements
Some leases require the owner to notify or obtain consent from the freeholder or managing agent before alterations begin. Requirements may depend on the proposed plumbing, flooring, ventilation or other changes, so the lease and building rules should be checked early.
Water Isolation and Shared Services
The existing water-isolation points should be identified before strip-out. Where services are shared or the local isolation valve is unsuitable, the building manager or another responsible party may need to coordinate a temporary water shutdown.
Access, Deliveries and Working Hours
Parking, lifts, staircases, loading areas and permitted working hours can affect how products, tools and materials reach the flat. Confirming these arrangements helps avoid disruption and unnecessary delays once work has started.
Protection of Communal Areas
Routes through entrances, corridors, staircases and lifts may require suitable protection while materials and waste are moved. The required method can be agreed with the customer and, where applicable, the managing agent before work begins.
Waste Removal and Storage
Flats may have limited space for storing bathroom products or removed materials. Waste collection, temporary storage and any restrictions on skips or communal bins should therefore be planned as part of the project arrangements.
Ventilation and Neighbouring Properties
Effective ventilation is particularly important where a bathroom has no external window. Work should also be planned with reasonable consideration for nearby residents, shared walls and the building’s permitted construction hours.
Arrange a free site visit so we can inspect the existing bathroom, discuss the proposed layout and review the practical access and building arrangements that may affect the work.
Understanding your budget
How Much Does a Bathroom Renovation Cost in London?
Bathroom renovation costs depend on much more than the size of the room. The existing condition, proposed layout, selected products and amount of plumbing, electrical, preparation and finishing work all influence the final quotation.
Similar Layout
Replacing the existing bathroom while keeping the main sanitaryware and service positions broadly unchanged will usually involve fewer alterations.
- Existing layout broadly retained
- Standard strip-out and preparation
- Replacement sanitaryware and finishes
- Limited plumbing or electrical alterations
Revised Specification
A complete renovation may include new service positions, improved lighting or ventilation, additional preparation and a more detailed finishing specification.
- Some layout or service changes
- Waterproofing and extensive tiling
- Bathroom furniture and storage
- Coordinated plumbing and electrical work
Bespoke Renovation
Complex layouts, premium products, specialist finishes or extensive remedial work normally require a larger budget and a more detailed installation programme.
- Major layout or drainage alterations
- Walk-in shower or wet-room arrangement
- Bespoke furniture and specialist finishes
- Extensive hidden-condition repairs
What affects the cost of the work?
The following points normally have the greatest effect on the quotation. They will be reviewed during planning and, where possible, during the initial site visit.
Existing Bathroom Condition
Damaged floors, unsuitable backgrounds, previous leaks, poor ventilation or defective plumbing may require remedial work before the new bathroom can be installed correctly.
Layout and Service Changes
Moving the toilet, bath, shower or basin can involve additional plumbing, drainage, floor and wall work. Retaining suitable existing positions can often reduce complexity.
Sanitaryware and Product Specification
Baths, shower systems, enclosures, toilets, basins, taps, vanity units and accessories vary considerably in price and installation requirements.
Tiling, Waterproofing and Finishes
Tile size, installation pattern, wall coverage, floor finishes, waterproofing requirements and specialist details all affect material quantities and installation time.
Electrical Work and Ventilation
New lighting, mirrors, extractor fans, heated towel rails, electric underfloor heating and other electrical work will be considered as part of the complete scope.
Access and Property Arrangements
Parking, upper floors, lift restrictions, permitted working hours, communal-area protection and waste-removal arrangements can affect the labour and logistics required for London properties.

A clearly defined project
What Your Bathroom Renovation Quotation Includes
A reliable quotation starts with a clearly defined scope. Following the site visit and discussion of your requirements, Growchance can prepare a quotation based on the bathroom, selected products and work known to be required—not simply the room’s dimensions.
Removal and Site Preparation
The scope can identify the existing sanitaryware, finishes and fittings to be removed, together with the expected waste-removal and initial preparation arrangements.
Plumbing and Drainage Work
Known alterations to hot and cold water supplies, wastes, valves, sanitaryware connections and fitting positions can be described according to the agreed bathroom layout.
Electrical Work and Ventilation
Where included, the scope can record proposed lighting, switches, extractor ventilation, mirrors, towel rails, underfloor heating and other relevant electrical items.
Walls, Floors and Waterproofing
The quotation can describe known wall and floor preparation, boarding, local repairs, waterproofing or tanking requirements and other backgrounds needed for the selected finish.
Tiling and Decorative Finishes
Tiled areas, floor finishes, grout and trim requirements, painting and other agreed finishing work can be set out using the available product and design information.
Installation of Bathroom Products
The scope can list the main sanitaryware, furniture, shower components, taps, screens, mirrors and accessories Growchance is expected to install.
Customer-Supplied and Contractor-Supplied Items
Responsibility for supplying the bathroom products, tiles, fittings and other materials should be recorded so that ordering, checking and delivery arrangements can be planned before installation.
Project-Specific Arrangements
Where relevant, the quotation can reflect known access restrictions, communal-area protection, permitted working hours, waste arrangements and other practical requirements discussed during the site visit.
Details that should be confirmed before work begins
Final product choices and site information can affect the work required. Confirming the following points helps turn the initial quotation into a practical project scope.
Product Details
Models, dimensions and installation information for the main bathroom products should be available before the relevant work begins.
Supply Responsibilities
The agreed scope should distinguish between materials supplied by Growchance and products purchased directly by the customer.
Known Exclusions
Work or products that are not included should be identified where possible, reducing uncertainty about the agreed project.
Programme Assumptions
Access, product availability, permissions and decisions by other parties can affect when the bathroom can start and how the work progresses.
Concealed leaks, damaged joists, unsuitable pipework, defective walls or floors and other hidden conditions may not be visible during the initial inspection. If previously concealed work is discovered, it should be explained and agreed before additional work proceeds wherever reasonably possible.
Arrange a free site visit so we can inspect the existing bathroom, discuss the layout and product choices, and begin defining an appropriate scope for your project.
From planning to completion
Our Bathroom Renovation Process
A successful bathroom renovation depends on careful sequencing. Growchance coordinates the preparation, plumbing, electrical work, waterproofing, installation and finishing around one agreed project scope.
Site Visit and Requirements
We inspect the existing bathroom, discuss how you want to use the space and review the proposed layout, products, finishes and practical requirements.
- Existing room and access reviewed
- Preferred layout and specification discussed
- Visible condition and constraints considered
Scope and Quotation
The known preparation, installation and finishing requirements are brought together into a quotation based on the proposed bathroom and information available at the time.
- Main work and responsibilities recorded
- Customer-supplied products identified
- Known exclusions and assumptions clarified
Products and Pre-Start Planning
Before work starts, the principal product dimensions, supply arrangements, access requirements and expected installation sequence should be confirmed.
- Main product information checked
- Deliveries and storage considered
- Access and property protection planned
Strip-Out and First-Fix Work
Existing sanitaryware and finishes are removed as agreed. The exposed room is assessed before the required plumbing, electrical, wall and floor preparation proceeds.
- Existing bathroom removed carefully
- Previously concealed conditions reviewed
- Plumbing and electrical first-fix completed
Waterproofing, Tiling and Fitting
The prepared room progresses through the agreed waterproofing, boarding, tiling and finishing stages before the bathroom products and fittings are installed.

- Waterproofing and finishes installed
- Sanitaryware, furniture and fittings connected
Finishing and Handover
Final fittings, sealants, decorative details and agreed finishing work are completed. The bathroom is then checked with the customer before project handover.
- Visible finishes and fittings checked
- Operating information discussed where relevant
- Final points recorded and addressed
Several trades, managed as one renovation
Bathroom work involves connected stages that must happen in the correct order. Coordinating the programme reduces confusion between preparation, services, waterproofing, tiling and final installation.
Property Protection
Access routes and nearby areas can be protected according to the property and agreed working arrangements.
Trade Sequencing
Plumbing, electrical work, preparation, tiling and fitting are arranged around the agreed construction sequence.
Progress Communication
Relevant decisions, discoveries and changes can be discussed as the project moves through each principal stage.
Finishing Checks
The completed bathroom is reviewed and any remaining agreed finishing points are identified before handover.
The programme depends on the room’s condition, layout changes, selected products, drying times, specialist finishes and whether hidden repairs are discovered after strip-out. We discuss the expected sequence before work begins, but avoid promising an unrealistic fixed duration before the full scope and product availability are understood.
