Layout, fittings and practical choices for a smaller bathroom
Bathroom refurbishment in a London flat starts with a practical question: what needs replacing, and what can stay? Keeping a workable layout can help control the scope, while changes to drainage, plumbing or electrical positions need to be allowed for before you choose the finishes.
This guide focuses on budget planning and useful improvements for a compact bathroom. There is no single price or completion time that fits every flat. Ask for a written scope based on the condition of the room, the products you want and the work needed to install them.
Set the scope before setting the budget
Separate essential work from optional upgrades. Repairing a problem, replacing worn fittings and changing the whole layout are different briefs. List what you want to keep, what needs removing and which items you will supply yourself, then ask what the quote includes.
Check allowances for preparation, plumbing, electrical work, ventilation, wall and floor finishes, fitting sanitaryware and removing waste. Agree how unexpected work will be assessed and approved rather than assuming every hidden condition is covered. Our renovation quote comparison checklist helps you compare the same scope across quotations.
Can you keep the existing bathroom layout?
Keeping the bath, basin and toilet in suitable existing positions can avoid some of the work involved in moving services. It is a starting point for discussion, not a reason to keep a poor layout or unsuitable pipework. Ask your installer to check the existing arrangements before ordering replacements.
Measure the room with doors, drawers and the shower screen open. Check the space needed to use each fitting, not just whether its dimensions fit on a plan. Compact sanitaryware, a mirrored cabinet or a different shower-door arrangement may make the room easier to use.
Choose fittings and finishes together
Compare complete product specifications rather than the headline price alone. A basin, tap, cabinet and waste arrangement need to work together. Wall-mounted fittings also need suitable support, so raise them before walls are finished.
For walls and floors, compare the preparation and fitting work as well as the material cost. Tiles, bathroom wall panels and suitable vinyl products offer different finishes. Check the chosen product's suitability for its intended use, including wet areas, and follow the manufacturer's installation requirements. A finish alone is not a substitute for a properly specified installation.
Plan lighting and ventilation before decorating
A small or windowless bathroom needs lighting that works around the mirror, basin and shower. Decide the positions before the walls and ceiling are finished, with electrical suitability and installation left to a qualified electrician.
Discuss ventilation alongside the layout rather than adding it as an afterthought. Ask the installer to assess the existing provision and what the proposed work needs. Do not assume that replacing a fan or opening a window will resolve every condensation problem.
Make storage useful without crowding the room
A mirrored cabinet can combine everyday storage with a mirror. Before choosing a recessed shelf, ask whether the wall construction and service positions allow it. Check that cupboards and drawers remain accessible beside the basin, toilet and shower.
Keep the items you use most often within easy reach. A simpler layout with enough usable storage can be more practical than fitting in every feature from a showroom display.
Agree access and disruption in a flat
Before work starts, check any relevant requirements with the freeholder or managing agent, including arrangements for access, working hours and shared areas. Confirm delivery and waste-removal arrangements with the contractor.
If this is your only bathroom, ask when the toilet, bath or shower will be unavailable and agree a practical arrangement for that period. Get a project-specific programme rather than relying on a general promise that every refurbishment takes the same number of weeks.
What should you leave to professionals?
Discuss any decorating or accessories you intend to handle yourself so they fit the agreed sequence. Leave plumbing and electrical work to appropriately qualified professionals. Your role is to confirm the layout, products and finish you want, then check the completed room using its ordinary controls.
Before handover, record any outstanding items and ask for the instructions and installation or compliance records relevant to the work. A room looking finished is not the same as every task being complete.
Discuss your bathroom refurbishment with BCS
BCS's London house renovation and refurbishment services include bathroom work. To discuss your flat, send BCS details of the existing bathroom and the changes you have in mind. Include whether you want to retain the layout and whether it is the flat's only bathroom, so the conversation starts with the work you actually need.
