Part P Bathroom Zone Regulations 2

Question 1

Are standard socket outlets permitted in Zone 2 of a bathroom?

Accepted Answer

No — socket outlets are not permitted in Zone 1 or Zone 2; only SELV shaving sockets (BS EN 61558-2-5) may be installed in Zone 2

Answer

Standard socket outlets are not permitted in Zones 0, 1 or 2 of a bathroom. Only specially designed SELV shaving units (conforming to BS EN 61558-2-5) containing an isolating transformer may be installed in Zone 2.

Question 2

Where is the closest permitted location for a standard socket outlet in a bathroom?

Accepted Answer

Outside Zone 2 (more than 0.6 m from the boundary of Zone 1) and where it cannot be reached from the bath or shower

Answer

Standard socket outlets must be installed outside Zone 2, at a safe distance from the bath or shower (more than 0.6 m from Zone 1 boundary), where they cannot reasonably be reached by a person using the bath.

Question 3

What type of shaving socket is permitted within Zone 2 of a bathroom?

Accepted Answer

A shaver supply unit conforming to BS EN 61558-2-5, incorporating an isolating transformer providing SELV

Answer

BS EN 61558-2-5 shaver supply units contain an isolating transformer and comply with specific safety requirements for wet areas; they provide SELV, preventing dangerous shock even if the supply becomes wet.

Question 4

What wiring methods are permitted in bathroom zones?

Accepted Answer

Cables concealed in walls or ceilings are permitted (if correctly zoned); surface wiring should be in appropriate conduit with connections in IP44 or higher-rated enclosures

Answer

In bathroom zones, wiring should ideally be concealed or if surface-run should be in appropriate systems; all accessories and enclosures within the zones must have the minimum IP rating required for that zone.

Question 5

Can a pull-cord switch be installed inside a bathroom zone?

Accepted Answer

Yes — a ceiling-mounted pull-cord switch with appropriate IP rating (minimum IPX4 in Zone 1) may be installed in bathroom zones

Answer

Ceiling-mounted pull-cord switches are commonly installed in bathroom zones; they must have the minimum IP rating required for the specific zone in which they are located (minimum IPX4 in Zone 1).
