How are the scale of provision requirements for a hospital determined?

Sanitary facilities must be provided for patients, staff and visitors. Several publications are applicable to the requirements of each group as follows: -

  • HTM 64 - provides detailed sanitaryware assembly specifications for use within patient and medical areas.
  • HBN 00-002 - provides specific sanitary room layout designs, utilising the assemblies in HTM 64, for patient and medical areas.
  • BS 6465 - provides scale of provision information that can be used to calculate the number of sanitary items required in staff and visitor washroom facilities.
  • Part M - provides information on the design and number of disabled facilities that are needed in staff and visitor washrooms.

Significant issues in non-clinical washrooms

  • Durability - vitreous china is the main sanitaryware choice as it is easy to cast into attractive shapes, easy to clean and will withstand constant use in most situations. Stainless Steel is also highly suited to use in healthcare as it can be fabricated to produced larger items, is resistant to chemical attack and has intrinsic hygiene properties.
  • Hygiene - cleanliness and hygiene are identified as the primary concern of washroom users. Many users have their own washroom rituals aimed at avoiding physical contact with surfaces. The challenge for the designer is to propose a layout and product selection that reduces contact with items in the washroom.
  • Maintenance - often overlooked in the purchasing decision, cleaning and maintenance costs can have a significant impact on the life costs of a washroom. Wall hung WC's make floor cleaning faster and more effective whilst walk-in ducts conceal services making the room look more attractive and easier to clean yet they still allow regular maintenance to be carried out easily.
  • Water economy - a major benefit that can be achieved without compromising hygiene, infection control or patient care. Taps with flow rate regulators can reduce water consumption by up to 80% according to the Environment Agency. Combine this with the use of waterless urinals, dual flush WC cisterns and the use of showers with thermostatic mixing valves and you are well on the way to achieving the Environment Agencies estimate that most buildings in the UK could reduce their water consumption by around 40%
