Few London bathrooms or kitchens are fitted onto a blank canvas. Most go into homes that have been altered many times – a Victorian terrace with its bathroom in the back addition, a converted flat where the soil stack serves three households, a 1930s semi with a separate toilet next to the bathroom. Good bathroom and kitchen plumbing starts with understanding what's already there.
Whether you need a new toilet fitted, a kitchen sink moved into an extension or a complete bathroom plumbed from first fix to finish, you can describe the job and compare quotes from plumbers who do this work across London.
Small rooms, shared stacks and hard water
Space drives a lot of London bathroom design. Wall-hung toilets and basins free up floor space, walk-in showers replace baths, and en suites appear in lofts and box rooms. All of that depends on drainage: in a flat, you may only be able to connect to the existing soil stack, which limits where the toilet can go. A plumber will usually check this before anything else.
In kitchens, extensions push the sink further from the stack, so waste runs become longer and need a steady fall. And because London's water is hard, many plumbers suggest fitting a water softener or scale reducer when the kitchen is replumbed, with a separate drinking-water tap – it's far easier to plan in at the start than to add later.
Access is part of the price in London too. Getting a new bath up four flights of stairs, protecting communal hallways and arranging parking all take time, and older buildings often hide surprises – lead supply pipes, iron wastes and boxed-in stacks – once the old suite is out.

Before the plumber arrives
- Have the new toilet, basin, sink or taps on site, unpacked and checked against the parts list.
- Find your stopcock so the water can be turned off quickly if needed.
- Clear the cupboard under the sink or the space around the toilet so there's room to work.
- Take photos of any boxing-in or access panels, and mention anything you know about old pipework.
Water supply in London
Most of London's water comes from the Thames and Lea and the chalk beneath the city, so it is hard. Limescale builds up in kettles, shower heads, thermostatic valves and combi boiler heat exchangers, and plumbers here are regularly asked to descale or replace parts, or to fit a water softener. The capital also has a huge stock of pre-war homes where old lead or iron supply pipes, shared supplies and tired stopcocks still turn up.

Bathroom & kitchen plumbing in London: common questions
Can I move the toilet in my London flat?
It depends on how far it is from the soil stack and whether there's enough fall. In flats, moving the toilet a short distance is often possible; moving it across the room may not be. A plumber needs to see the layout.
Should I fit a water softener with my new London kitchen?
If limescale bothers you, it's a good time to do it, because the plumbing is already being changed. Your plumber will usually add a separate unsoftened tap for drinking water.
Do I need the freeholder's permission for bathroom plumbing in my flat?
Many leases require consent for alterations, especially if they involve shared pipework or the soil stack. Check your lease before work starts.
