Protect the bedroom
The bed, wardrobes, circulation and natural light still need to work after the new enclosure is formed.
Bedroom-to-en-suite conversion
Add an en-suite to a bedroom—without ruining the bedroom.
A builder-led approach to creating a private bathroom inside an existing London bedroom.
Bedroom conversion
An en-suite is a new room—not three fittings in a corner.
Adding an en-suite to a bedroom normally means creating walls, a doorway, drainage, water supplies, ventilation, electrics, waterproofing and a finish that still allows the bedroom to work properly.
Find the drainage route
The WC soil connection and shower waste fall usually determine where the en-suite can realistically sit.
Plan privacy and noise
Door position, extract noise, flushing and pipework need thought so the space feels private and comfortable.
Practical planning
A buildable layout starts behind the finished tiles.
The most attractive drawing is useless if the waste cannot fall, the fan cannot discharge outside or the hot-water system cannot support the chosen shower. We assess the hidden work before the design is fixed.
- Measure the bedroom and furniture zones
- Check soil pipe and waste routes
- Assess water pressure and hot-water supply
- Plan ventilation to outside
- Consider doors, sound and maintenance access
- Confirm building-control and electrical requirements

Questions
Frequently asked questions
Can an en-suite be formed inside an existing bedroom?+
Often, yes, provided the bedroom remains usable and there is a workable route for drainage, water, ventilation and electrics. A survey is needed before confirming the layout.
Where is the best place to position it?+
Usually near an existing soil pipe, bathroom or outside wall, but furniture layout, windows, doors, privacy and waste-pipe falls all matter.
Will the room need new walls?+
Most bedroom conversions use carefully positioned stud walls and a new door, with acoustic, waterproofing and service considerations built into the specification.
How long does the work take?+
Timescales vary with drainage, structure, access and finish. A new en-suite normally involves several trades and should be planned as a proper building project rather than a quick fitting job.
Start with the real room
Let us check what can actually be built.
Send photographs and a rough description, visit our Fulham consultation office, or arrange a home survey. We will assess space, drainage, water, ventilation and the practical build route before the design is finalised.
