How much does a bathroom renovation cost in London?
The cost depends on the room, any layout changes, the products you choose and how much building work is needed, so we don’t use one standard price. Once the design and scope are agreed, your written proposal sets out the full cost.
Can Arch manage the whole bathroom renovation?
Yes. We take a bathroom renovation or refurbishment from design and products through strip-out, plumbing, electrics, tiling and fitting. We take on bathroom-only projects as well as bathrooms within a wider home or flat renovation.
Do you do small bathrooms and en suites?
Yes. Family bathrooms, small bathrooms, shower rooms, en suites and downstairs cloakrooms, from simple and practical to fully bespoke.
Can you change the bathroom layout?
Where the room and the technical conditions allow. Moving drainage, water supplies or electrics can affect what’s possible, the cost and the timing, so we look at it before the specification is finalised.
Will you fit a bathroom I’ve bought elsewhere?
No. We only fit bathrooms we supply, so one company answers for the products and the fitting. If you have your own fitter, we can supply the products and your team can fit them.
Which parts of London do you cover?
We work across London from our Hammersmith showroom, including West, North West and South West London. See our pages for Chiswick, Fulham, Kensington and Wimbledon.
Where is your bathroom showroom?
At 323–325 King Street, Hammersmith, London W6 9NH. It’s about 180 m² over two floors, so you can see and touch everything before you choose. Visit the showroom.
