FOREWORD

This Indian Standard (Second Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by the Water Supply and Sanitation in Building Sectional Committee had been approved by the Civil Engineering Division Council.

Installation of sanitary appliances in any public or private building is usually governed by municipal bye-laws and rules thereunder. These are intended to regulate proper layout of the appliances and their connections so that wastes are suitably disposed off to drains without causing insanitary conditions and nuisance to public. Noting the variations in the bye-laws and rules framed by different authorities in the country, this Indian standard was first published in 1962 and subsequently revised in 1973 to ensure fulfilment of minimum requirements. This revision of the standard provides more details of various dimensions necessary for fixing in position of various sanitary appliances. The revision incorporates reference to new/latest Indian standards.

Sketches have been included which show typical layout of sanitary fixtures in water closets, bathrooms, kitchens, etc. They are only illustrative and are not intended to limit the design to the types shown.

7.3 Bidet

The provisions of bidet is often a luxury. The materials needed for manufacture may be earthenware or fire clay or G.R.P. or metal. The minimum space dimensions for installation of bidet shall be 900 mm in width and 1 300 mm in depth. This appliance is generally installed very near to W.C. The spacing between W.C. and bidet shall not be less than 800 mm from central axis of both appliances and minimum 600 mm from front edge of the bidet. Bidet with mixer and anti-scalding device shall be given preference.

7.4 Shower

Ready made shower tray for standing bath or sunken floor for squatting bath shall be individual’s. Sunken bath floor level shall not be more than 60/70 mm. Shower head height shall be governed by users height, may be overhead for men only 1 750 mm, however, 150 mm clearance shall be provided for above overhead.

In case of shower, projected from wall, it shall not be more than 450 mm and height not exceeding 2 200 mm from floor level. The shower valves or mixing values shall be placed near entrance to shower. Shower curtain rod shall be optional (see IS 781:1984 and IS 1701:1960).

7.5 Toilet

Toilet consists of minimum three fixtures such as shower stall/bath tub, wash basin and water closets. It is common practice to provide four fixtures, like tub and shower stall, wash basin/dressing counter and water closets. Luxurious type toilet consists of five fixtures name bath tub, shower stall, water closet, bidet and counter fitted with wash basins, with full length of mirror. The arrangement of these fixtures are made with due consideration to clearances and piping system (see Fig. 3).

7.6 Water Closets

Generally squatting type W.C. seats/pans are very common in rural and urban areas. However, the provision of western type i.e. down flash type of W.C. seats in toilet is popular in metropolitan towns among the users suffering from arthritis, or piles etc. Water closet space should accommodate not only the pan but also a provision for water tap, tumbler, wall pegs, toilet paper holder, flushing valves, cistern high or low and storage for cleansing agents etc. Some times water closets seat is used as a reading space also by few users, needs more than minimum floor area. The design of W.C. shall include planning for optimum convenience and privacy for all the members of the family.

Some general planning guidelines are given in 7.6.1 to 7.6.2 (see Fig. 4) (See IS 2556 Part 7 to 15 and IS 2548 Part 1 and 2 and IS 774:1984 and IS 7231:1984).

7.7 Hand Wash Basin

The provision of hand wash basin in housing or in public toilet has become a necessity for personal care. It is generally used in standing posture for washing hands, face, hairs, shaving and also for make-up. The design, shape, size and colour of wash basins are available in varying degrees. The installation of wash basin may be mounted on pedestal or fixed on wall with/without brackets. In case of corner location special type shall be used. Since wash basin forms the part of wet area in the building, careful planning of space as well as proper selection of appliance and convenient arrangement is needed.

Some general planning guidelines are as given in 7.7.1 to 7.7.3 (see Fig. 3 and 5). (See IS 771 (Part 1 to 3) and IS 2556 (Part 1 to 5)

7.7.1 Arrangements

It will be necessary to provide multi use of spaces in a toilet. Due consideration shall be given to the possibilities of more than one person using wash basin at certain time of a day in a house. It will be desirable to provide minimum 500 mm distance from the adjacent obstruction wall to the central axis of wash basin and width; 600 mm from front edge to the opposite/obstruction point to perform various activities. The spacing shall be measured from the central axis of the wash basin irrespective of size and shape. Due care shall be given for fixing outlets for hot and cold water supply taps, stop valves. It shall be proper to follow manufacturer’s instructions before wash basin is fixed.

7.7.2 Mirror

It is a common practice to install mirror/medicine cabinet with mirror above wash basin. Occasionally small shelf is also provided for keeping daily use items. The minimum size of mirror shall not be less than 0.20 m and each side not less than 450 mm. The bottom line of mirror shall not be less than 1 200 mm from the finished floor level.

7.7.3 Materials

Materials and finishes that minimize the maintenance and cleaning shall be used.

Some of the critical dimensions are given in Fig. 3 for installation.

7.8 Urinals

Privacy ‘from and within’ is important criteria for the design of installations in public urinals. The concept of privacy in all culture of society has played a role in the design of fixture and fittings, employed in personal hygine.

The design and installation of fixtures such as stall type urinals (without partition) and wall hanging urinals with partition often lack the privacy ‘within’ and arrangement of installation similarly lack privacy ‘from’ for the users. Therefore, it shall be imperative for the designer to pay attention while planning public conveniences. The concept of squatting type urinals may also be considered particularly for females.

Some general planning guidelines are as given in 7.8.1 to 7.8.3 (see Fig. 6). (See IS 2556 (Part 6/Sec 1 to 6) and IS 2326:1987 and IS 7231:1984)

7.8.1 Arrangement

It shall be important to provide basic elbow space and consideration shall be given to privacy. The arrangement shall vary according to the size and shape of the available space. But proper circulation, movement space, functional use of fixtures and fittings shall not be ignored. Avoid installation of series of wash basins with mirror at right angle or opposite to the urinals. A suitable storage space for brooms, cleaning agents etc, should be made. The location of flushing cistern, screen height, constant water supply should also be taken into account.

7.8.2 Materials

Materials and finishes that minimize the maintenance and cleaning shall be used.

7.8.3 Lighting and Ventilation

Good ventilation shall be provided to dispel odours, if necessary, by artificial ventilation. Care should be exercised in its selection and placement of windows as light source as well as ventilation.

Some of typical dimensions for installation are given in Fig. 6.

8 WORK ON SITE

8.1 Chases and Ducts

A check shall be made to see that all holes, chases and ducts required for pipework have been properly provided.

4

8.2 Delivery of Appliances

Before delivery of appliances, suitable storage space, which can be retained until the assembly period, should be provided. Upon arrival all appliances shall be carefully checked to ensure that they are in accordance with the requirements and free from defects and damage.

8.3 Siting of Appliances

The outlets of water closet pans and similar appliances shall be examined to see that outlet ends are abutting on the receiving pipes before joining. It is also necessary to make sure that the receiving pipe is clear of obstruction. Attention shall be given to the possibility of movement and settlement from other causes, and also to noise transmission. Overflow shall be so arranged as to give visible warning of discharge and should always have fall to the outlet. When terminating externally, the overflow shall have sufficient projection to throw the discharge clear of the wall, but the projection shall be limited to avoid unsightliness.

8.4 Fixing of Appliances

A check shall be made to ensure that the necessary facilities have been provided for supporting wash basins, sinks and flushing cisterns. Where the built-in types of brackets are used, they shall already have been fixed by the building contractor and where the wall fixing types are involved, the wall finish shall have been arranged to make provisions for them. Care shall be taken when fixing sinks to ensure that they drain satisfactorily to the outlet.

8.5 Protection of Appliances

Care shall be taken at all times, particularly after fixing, to protect appliances from damage. Glazed, enamelled and plated surfaces of appliances can be irreparably damaged by carelessness during subsequent operations. All orifices should be temporarily plugged during the progress of the work to prevent obstruction. Appliances shall finally be cleaned of all marks of cement, lime, oil, paint, etc.

9 INSPECTION AND TESTING

9.1 Inspection

On completion of the work, all appliances, materials and workmanship shall be carefully examined for defects.

9.2 Testing

Comprehensive tests of all appliances should be made for simulating conditions of use; overflows should be examined for obstructions.

10 MAINTENANCE

10.1

Appliances need frequent cleaning to maintain them in a good sanitary condition and to preserve their appearance.

10.2

If cleaning has been neglected, it may be necessary to use a solution of bleaching powder (NaOCl) together with hot water to remove surface stain from ceramicware. To restore the lustre of the porcelain glazed surface, hot water with a paraffin moistened cloth is often successful. Abrassive powders, spirits of salts or other acid solutions are detrimental and should not be used on such surfaces. The renewal of tap and valve washers should receive prompt attention to avoid waste of water and damage to valve sealing and surface of appliance.
