Bathroom types
Shower rooms in garden rooms and outbuildings
What we look at first
- Buried supply pipework needs to be at a sensible depth and sleeved where it enters the building
- with a drain point for winter shutdowns.
- Waste to the main drainage needs both fall and a rodding point; where levels are marginal
- a pumped station is the honest solution.
- Electrical supply to an outbuilding is a separate piece of work with its own protection requirements
- and it should be planned before the room is lined.

Before you commit
Electrical supply to an outbuilding is a separate piece of work with its own protection requirements, and it should be planned before the room is lined.
Questions we get asked
Is planning permission needed?
Building work and drainage connections have their own approvals; the outbuilding's own status is a separate question worth checking early.
Will the pipes freeze in winter?
Not if the pipework is insulated, kept inside the insulated envelope where possible, and drainable when the building is unused.
Add outbuilding shower rooms to a wider project?
Plenty of this work happens alongside other jobs in the house. Tell us the whole picture and the sequencing gets easier.
