FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60364-7-701 has been prepared by IEC technical committee 64:
Electrical installations and protection against electric shock.
This second edition cancels and replaces the first edition published in 1984, and constitutes a
technical revision.
The main changes with respect to the previous edition are listed below:
– Extension of the requirements of zone 3 for the whole area of the room containing a bath
tub or a shower basin and consequently deletion of any reference to zone 3.
– Applicability of the requirements of this part when fixed prefabricated bath or shower units
are installed.
– Clarification of requirements concerning the local equipotential bonding.
– Introduction of particular requirements for specific switchgear, accessories and current-
using-equipment installed in zone 1 and 2.

LOW-VOLTAGE ELECTRICAL INSTALLATIONS –

Part 7-701: Requirements for special installations or locations –
Locations containing a bath or shower



701 Locations containing a bath or shower
701.1 Scope
The particular requirements of this part of IEC 60364 apply to the electrical installations in
locations containing a fixed bath (bath tub) or shower and to the surrounding zones as
described in this standard.
This standard does not apply to emergency facilities, e.g. emergency showers used in
industrial areas or laboratories.
NOTE 1 For locations containing a bath or shower for medical treatment, special requirements may be necessary.
NOTE 2 For prefabricated bath and/or shower units, see also IEC 60335-2-105.
NOTE 3 In Germany, the term locations may be interpreted as rooms of buildings.
701.2 Normative references
The following referenced documents are indispensable for the application of this document. For
dated references, only the edition cited applies. For undated references, the latest edition of
the referenced document (including any amendments) applies.
IEC 60364-4-41, Low-voltage electrical installations – Part 4-41: Protection for safety –

701.30 Assessment of general characteristics
701.30.1 General
When applying this standard, the zones specified in 701.30.2 to 701.30.4 shall be taken into
account. For fixed prefabricated bath or shower units, the zones are applied to the situation
when the bath or shower basin is in its usable configuration(s).
Horizontal or inclined ceilings, walls with or without windows, doors, floors and fixed partitions
may limit the extent of locations containing a bath or shower as well as their zones. Where the
dimensions of fixed partitions are smaller than the dimensions of the relevant zones, e.g.
partitions having a height lower than 225 cm, the minimum distance in horizontal and vertical
direction shall be taken into account ( see Figures 701.1 and 701.2 ).

60364-7-701  IEC:2006 – 11 –
For electrical equipment in parts of walls or ceilings limiting the zones specified in 701.30.2 to
701.30.4, but being part of the surface of that wall or ceiling, the requirements for the
respective zone apply.
NOTE In Ireland, a zone 3 exists within 2400 mm horizontally from zone 2, and 750 mm above zones 1 and 2.
701.30.2 Description of zone 0
Zone 0 is the interior of the bath tub or shower basin, see Figure 701.1.
For showers without basin, the height of zone 0 is 10 cm and its surface extent has the same
horizontal extent as zone 1, see Figure 701.2.
NOTE 1 In Spain, for showers without basin, the height of zone 0 is 5 cm.
NOTE 2 In Germany this requirement is not relevant.
701.30.3 Description of zone 1
Zone 1 is limited
a) by the finished floor level and the horizontal plane corresponding to the highest fixed
shower head or water outlet or the horizontal plane lying 225 cm above the finished floor
level, whichever is higher,
NOTE 1 In Belgium, Denmark, Hungary and Italy, if the bottom of the bath tub or shower basin is located
higher than 15 cm from the floor level, the horizontal plane is located 225 cm above the bottom of bath tub or
shower basin.
NOTE 2 In the Netherlands 225 cm is replaced by 260 cm.
NOTE 3 In the Czech Republic and in Spain the zone 2 is considered above the zone 1 as far as the ceiling or
the horizontal plane lying 300 cm above the finished floor level, whichever is higher.

b) by the vertical surface:
– circumscribing the bath tub or shower basin (see Figure 701.1),
– at a distance of 120 cm from the centre point of the fixed water outlet on the wall or
ceiling for showers without basin (see Figure 701.2 ).
Zone 1 does not include zone 0.
The space under the bath tub or shower is considered to be zone 1.
NOTE 4 In Spain, and for showers without basin, where the water outlet is fixed the vertical limit is fixed at 60 cm
around the water outlet.
NOTE 5 In Spain, the space under the bath tub or shower basin accessible without the use of a tool is considered
to be zone 1. If it is accessible only with the use of a tool, it is considered to be neither zone 0, nor 1 nor 2.
701.30.4 Description of zone 2
Zone 2 is limited
a) by the finished floor level and the horizontal plane corresponding to the highest fixed
shower head or water outlet or the horizontal plane lying 225 cm above the finished floor
level, whichever is higher,
NOTE 1 In the Netherlands, 225 cm is replaced by 260 cm.
b) by the vertical surface at the boundary of zone 1 and the parallel vertical surface at a
distance of 60 cm from the zone 1 border ( see Figure 701.1).
For showers without basin, there is no zone 2 but an increased zone 1 is provided by the
horizontal dimension of 120 cm mentioned in the second dash of 701.30.3 b) (see Figure
701.2).
NOTE 2 In Spain, zone 2 exists in any case.
