You may know your bathroom needs updating, but deciding what to change, how much to spend, and where to begin is often harder than choosing tiles. The room affects your daily routine, ongoing maintenance, and how future buyers view the property.
This bathroom renovation planning guide for UK homeowners in 2026 explains the decisions to make before booking trades, the likely costs and timescales, and how to keep disruption manageable.
Start with the room, not the finishes
Begin by deciding what the bathroom needs to do. A busy family bathroom in Maidstone may require a bath, practical storage, and easy-to-clean surfaces. A smaller en suite in Sittingbourne might work better with a walk-in shower and wall-mounted fittings.
Keeping the existing layout is usually the most cost-effective option because the water supply and waste connections remain close to their current positions. Reconfiguring the room can improve movement and storage, but moving a toilet is often more involved because the soil pipe restricts where it can go.
Prime Construction’s bathroom fitting service can include plumbing, building work, replastering, tiling, fitting, and decoration, so the layout can be considered as part of one coordinated project. Call 01795 431378 or email info@primeconstructionltd.co.uk.
The best bathroom plans settle the layout, drainage, ventilation, and lighting before the finishes. Getting that order right protects both the design and the budget.
Set a realistic budget
The final cost of a bathroom renovation depends on the size of the room, the products selected, the amount of tiling, access to the property, and whether plumbing or structural changes are needed.
It is sensible to keep part of the budget aside for work that only becomes visible after strip-out. This might include damaged floorboards, ageing pipework, uneven walls, or additional preparation before waterproofing and tiling.
VAT is normally charged at the standard rate. Different rules may apply to certain qualifying disability adaptations or eligible work on properties that have been empty for a specified period.
Choose materials around everyday use
Create a simple palette covering the walls, floor, sanitaryware, taps, shower fittings, and storage. Think about how each surface will perform, not only how it looks in a showroom.
Large tiles can reduce the number of grout lines, while smaller tiles may be more suitable where a wet-room floor needs to slope towards the drain. Take samples into the room before making a final decision because natural and artificial light can change how colours and textures appear.
Lighting also deserves early attention. General ceiling lighting should be supported by focused lighting around the mirror, using fittings that are suitable for bathroom zones.
Waterproofing should never be treated as an optional extra. Tiles and grout are not a complete waterproof barrier, so showers and wet rooms need a properly prepared waterproof layer beneath the visible finish.
Check structural and technical choices early
A traditional bathroom with a bath or shower tray is generally simpler to install than a full wet room. Wet rooms require carefully formed floor falls, suitable drainage, and thorough waterproofing.
Underfloor heating can make the room more comfortable, particularly where tiles are used, but it affects the floor build-up and needs to be planned before tiling begins.
A straightforward like-for-like refit will not usually require Building Regulations approval. Approval may be necessary where the work affects drainage, electrics, ventilation, structure, or creates a bathroom in a new part of the property.
Ventilation is particularly important because bathrooms produce high levels of moisture. Listed buildings and properties in conservation areas may also need additional checks, especially where external vents or structural alterations are proposed.
How long does a bathroom renovation take?
A full bathroom refit commonly takes around two to three weeks when products are available, the design is agreed, and no major hidden defects are discovered.
A typical sequence is:
- Strip-out: 1 to 2 days.
- First-fix plumbing and electrics: 2 to 3 days.
- Wall preparation and tiling: 3 to 5 days.
- Second-fix plumbing and fitting: 2 to 3 days.
- Decoration, sealing, and finishing: around 2 days.
The programme may be longer if walls are moved, bespoke products are ordered, extensive repairs are needed, or the project includes a wet room.
Prime Construction also provides house refurbishment services when a bathroom forms part of a larger renovation involving several rooms or trades.
Plan for living without the bathroom
Before work starts, confirm when the toilet, shower, bath, and water supply will be unavailable. This is especially important in a property with only one bathroom.
Some homeowners stay elsewhere for part of the project. Others arrange temporary washing facilities or agree that the toilet will be reconnected overnight where the work allows.
Clear toiletries and personal belongings from the room before the first day. It also helps to agree working hours, access arrangements, parking, waste removal, and how progress updates will be provided.
Common planning mistakes include choosing finishes before confirming the layout, allowing too little lighting, overlooking ventilation, and reducing the waterproofing specification to save money. Last-minute product substitutions can also create fitting problems or delay the next trade.
A practical plan for a better bathroom
A successful bathroom renovation connects the design with plumbing, structure, ventilation, budget, and the order of work. Keep the existing layout where it functions well, spend carefully on the elements that protect the room, and choose finishes that suit the household rather than following a short-lived trend.
A well-planned bathroom can improve buyer appeal and may support an increase in property value. However, any uplift will depend on the local market, the condition of the original room, the standard of work, and whether the project adds facilities or simply replaces an existing bathroom.

Frequently Asked Questions
How should I plan a bathroom refurbishment?
Start with how the room will be used. Confirm the layout, drainage, lighting, ventilation, and budget before choosing tiles or fittings.
Can I move the toilet to another wall?
Possibly, but the route of the soil pipe, the floor structure, and the required drainage fall must all be checked before the layout is approved.
How long does bathroom tiling take?
Tiling usually takes three to five days, including preparation and necessary curing time. Complex patterns or repairs to the walls and floor may extend this.
Do I need planning permission for a new bathroom?
Planning permission is not normally needed for an internal bathroom refit. Listed buildings, extensions, and some structural alterations may require consent, while Building Regulations can still apply.
