Bathroom Renovation Checklist for London Homes (2026)
A full bathroom renovation involves more decisions than most homeowners expect going in. Long before you get to tile colour, there’s underfloor heating, extractor specification, storage, and half a dozen small fittings that are easy to forget until the room is already stripped out. Working through this checklist before your first consultation means a more accurate quote and fewer surprises once work begins.
Quick version: decide your layout and must-haves first, then work through sanitaryware, tiling and storage, then electrics and ventilation, then the practical logistics, timeline, access, and deliveries. Bring this list to your consultation and your project coordinator can talk you through anything you’re unsure of.
Start with the big-picture decisions
- Layout: are you keeping the existing layout, or moving the toilet, basin, or shower? Moving plumbing runs adds time to the project, so it’s worth deciding this early.
- Accessibility: is this a factor now, or likely to be in future? A fully accessible bathroom is specified differently from the outset rather than retrofitted later.
- Underfloor heating: yes or no, and if yes, what colour and style of thermostat?
Sanitaryware & fixtures
- Bath tub, bath panel, bath tap, bath screen (if you’re keeping a bath)
- Shower tray, shower screen, shower valves (if you’re adding or keeping a shower)
- Toilet system and flush button, toilet pan, toilet seat
- Basin, unit or pedestal, and basin taps
Tiling, surfaces & storage
- Wall and floor tiles, tile trims, and grout colour
- Mirror or mirrored cabinet
- Niche recessed shelving built into the shower wall
- Additional shelving
Fixtures & finishing touches
- Door bar/threshold
- Toilet paper holder, towel holder, toothbrush holder
- Towel rail and valves
Electrics & ventilation, easy to forget, hard to retrofit
- Extractor fan
- Shaver socket
- Light fitting, colour temperature, and isolator switch
Bathroom electrics sit within specific safety zones around water, so this work should always go through a qualified electrician as part of the renovation itself, not as an afterthought once the room is finished.
Practical considerations most checklists skip
- Building regulations: significant plumbing or electrical changes may need to be notified to building control. A renovation company should flag this as part of scoping the job, not leave you to work it out.
- Timeline and access: if this is your only bathroom, plan for reduced access during the works and ask what temporary arrangements, if any, are available.
- Deliveries and storage: fixtures and tiles typically need to arrive and be checked before installation starts. Confirm who’s managing supply and where materials are stored until they’re needed.
From checklist to quote
Working through this list isn’t about having every answer before you speak to anyone; it’s about walking into that first conversation knowing what you care about, so the quote you get back actually reflects your project. At A&G, this list forms the basis of the pre-start meeting: your project coordinator goes through it item by item, confirms scope, and puts together an itemised quote before any work begins.
FAQ
How long does a full bathroom renovation take? Renovations that keep the existing layout are typically the quickest; anything involving structural changes or moved plumbing takes longer. Your project coordinator will confirm a realistic timeline once the scope is agreed, rather than before.
Do I need to move out during the renovation? Usually not, but access to the bathroom itself will be limited for the duration. If it’s your only bathroom, raise this at the consultation stage so alternative arrangements can be planned.
Can I supply my own tiles or fixtures? Often, yes, many renovation companies, A&G included, can incorporate items you’ve already chosen alongside what they source. Confirm this at the quote stage so it’s reflected in the itemised price.
What’s included in a full bathroom renovation with A&G? Strip-out, waterproofing, tiling, plumbing, electrical coordination, fitting, and full project management, backed by a 12-month labour guarantee and £5 million public liability insurance.
Do you offer accessible bathroom renovations? Yes, a fully accessible or disabled-adapted bathroom is a complete project in its own right, specified from the outset rather than added on afterward.
