Loft bathrooms
in London.
A loft bathroom is a plumbing and coordination job as much as a bathroom. Everything has to be brought to a floor that was never designed to have it.
What it involves
New services, three floors up.
Loft bathrooms sit at the end of the longest service runs in the house. Waste often cannot fall under gravity to the existing stack, mains pressure may not carry to the top floor, and the floor structure was designed for storage rather than a filled bath and a tiled floor. Add restricted head height under a rafter line and you have a job where the coordination matters more than the finish. It is also the job where poor waterproofing does the most damage, because everything below it is habitable.
What is included
Every loft bathroom we build, as standard.
- Structural check on floor loading before design
- Soil connection or pumped waste to the stack
- Pressure assessed and pump specified where needed
- Head height and rafter line worked into the layout
- Insulation and condensation risk addressed properly
- Full tanking, with extra attention to floor junctions
- Extract ducted through the roof, correctly terminated
- Coordination with any loft conversion trades
About loft bathrooms
Questions we are
asked most.
Will the floor take it?
That is the first thing we check. A filled bath, tiling and a screed add significant load. Where joists need strengthening we say so before anything else is discussed.
What if there is not enough water pressure?
Common on third floors, especially with a combi. Options range from a pump to changing the system entirely. We assess it at survey rather than discovering it at second fix.
Can it connect to the existing soil stack?
Usually yes, though the run may be long and the gradient tight. Where gravity will not serve we use a pumped system, and we will explain the trade-offs before you commit.
