Enhancing the accessibility, adaptability and usability of Scotland's homes: consultation

Annex N – Section 14 of Part 1 of the current Housing for Varying Needs design guide: Bathrooms and WC compartments

The clauses within Section 14 of Part 1 of the current Housing for Varying Needs design guide are set out in the table starting on the next page. Where a clause relates to dwellings specifically for older or ambulant disabled people, dwellings specifically for older people, or dwellings for wheelchair users, this is highlighted within the table.

Column 3 of the table shows our proposal for each clause for the update to Part 1 of the Housing for Varying Needs design guide. In the case of the clauses that we are proposing to retain within the updated guide, the design criteria that we are proposing to include ‘as standard’ in future dwellings delivered to Housing for Varying Needs standards through the Affordable Housing Supply Programme for each category of need – and to accommodation delivered through the Gypsy/Traveller Accommodation Fund (or subsequent funding) where the standard is relevant in Gypsy/Traveller accommodation – are highlighted in the third column of the table.

Informed by the proposals detailed in Chapter 3, column 4 shows which clauses are proposed to be introduced into building standards and guidance to implement the Scottish Accessible Homes Standard, along with those that are not applicable for inclusion.

It is important to note that the final proposals contained in the table will be subject to change based upon the outcome of the consultation.

14 Bathrooms and WC compartments

14.1 The needs

14.1.1 Bathrooms must be of a design and size that allows for different and changing needs.

14.1 The needs

14.1.2 Space in a bathroom allows for flexibility in its use and layout. The majority of adaptations needed on medical grounds to existing housing are because bathrooms are unsuitable or inadequate. Many bathrooms are designed to minimum dimensions dictated by the length of the bath and the combined width of the fittings. Such bathrooms can be awkward for anyone, with the door swing taking up a large part of the clear floor area and lack of space for a chair or stool for bathing and drying young children.

Retain

Proposals for the Scottish Accessible Homes Standard

See Sections 14.9 to 14.17.

14.2 General requirements for bathrooms

14.2.1 The layout and dimensions of all bathrooms must accommodate different needs and allow for: - a bath or a shower so that the occupant can have whichever best suits their needs - space for someone in a wheelchair to enter and close the door – this may be achieved by the door opening outwards, provided this does not cause an obstruction in the hall or landing (see also 14.2.7) - space for a stool or small chair - fittings with the necessary activity spaces as given below, and - access to window and/ or ventilation control, see 16.3.

Proposed Housing for Varying Needs update

Retain – although the text ‘…so that the occupant can have whichever best suits their needs’ would not be included in the updated guide as the intended occupant is not always known at build stage.

Please note that the following updated design criteria would require to be delivered ‘as standard’ in future:

‘The layout and dimensions of all bathrooms must accommodate different needs and allow for: - a bath or a shower - space for someone in a wheelchair to enter and close the door

- space for a stool or small chair, and - fittings with the necessary activity spaces [as given below].’

Proposals for the Scottish Accessible Homes Standard

Include (see Chapter 3, Table 1).

14.2 General requirements for bathrooms

14.2.2 Walls adjacent to the WC and around the bath should be of a construction that allows for the secure fixing of grab and support rails should these be needed. The walls should either be of solid construction or framed partitions with plywood sheathing. Consideration needs to be given on the means of fixing where supports are to be fixed to dry lined external walls.

Proposals for the Scottish Accessible Homes Standard

See Section 17.5.

14.2 General requirements for bathrooms

14.2.4 Dwellings specifically for older or ambulant disabled people: The baths versus showers debate cannot easily be resolved. It has two elements, peoples’ needs and their preferences. A person's particular disablement or mobility problem may result in them being unable to use a bath, and others unable to use a shower, or needing the use of a bath for therapeutic reasons. The incidence of each of these situations is difficult to predict. People will also have a preference for a bath or for a shower and though in recent years the number of dwellings with showers has increased, a bath is what many people are accustomed to and enjoy. Showers on the other hand are more economical in use and save both energy and water.

Proposed Housing for Varying Needs update

Remove – this clause is considered unnecessary.

Exception C Clause applies to housing designed for specific user group.

14.2 General requirements for bathrooms

14.2.5 Dwellings specifically for older or ambulant disabled people: It is advisable to provide a bath with a shower over it in some dwellings and walk-in showers in others, to cater for different needs within any development. The proportion of each will depend on the propensity of needs and preference among the likely user group.

14.5 Baths

14.5.1 The bath position must not be hard against a wall at both ends nor below a window. There should be some flexibility in the positioning of the bath – a space of at least 400mm at the head of the bath can accommodate a shelf and provides space for the use of bathing aids if required. A shelf at the tap end gives easier access to the taps and the full length of bath if other fittings are adjacent.

Please note that the design criteria set out in the first sentence would require to be delivered ‘as standard’ in future in cases where a bath is provided.

Proposals for the Scottish Accessible Homes Standard

Include (see Chapter 3, Table 1).

14.5 Baths

14.5.2 When a bath is provided it should have a wall-mounted shower over it (or at least the necessary service connections), as an energy saving convenience and to allow for the needs of some people who are unable to use a bath. This also has the advantage that the situation is more easily and economically adapted to provide a shower tray/ cabinet should this be needed. The shower position should be as described in 14.6.2.

Proposals for the Scottish Accessible Homes Standard

Not applicable

Exception C Clause applies to housing designed for specific user group.

14.5 Baths

14.5.5 Dwellings specifically for older or ambulant disabled people: Shorter length, shallower baths are manufactured specifically for use by older or disabled people. These are of dimensions that prevent someone becoming completely immersed, but are found to be too small by many people and are very unsuited to bathing aids. A standard size bath is therefore generally preferred.

14.6 Showers

14.6.8 Dwellings specifically for older or ambulant disabled people: The shower head should be 1300mm – 1800mm from the shower tray or bottom of the bath and be positioned so that it is suited to a person using a seat. The controls should be at a maximum height of 1050mm from the shower tray, or the bottom of the bath, so that they can be reached from a seated position.

Proposed Housing for Varying Needs update

Retain – although the updated guide would make clear that these dimensions also apply ‘from the floor’ in the case of a shower area with a floor gulley.

14.7 Rails and supports

14.7.2 Dwellings specifically for older or ambulant disabled people: Some users will need grab rails and supports from the outset but these should preferably not be provided as a matter of course. Their presence may be resented if they are not needed, but also it is essential that their form and position are suited to, and safe for, a particular user. Grab rails and supports should whenever possible be fitted only after the needs of the occupant have been assessed. Rails that are at an incorrect height for a particular user can be dangerous. If it is considered necessary to provide these on a standard basis they should be as Fig 14.6 and 14.7 or as BS 5810 [5]

14.9 General provision for wheelchair users

14.9.1 Dwellings specifically for wheelchair users: The layout and dimensions of the bathroom must allow for a bath, a shower area with floor gulley, a wash-hand basin and WC and their associated activity areas. The room should be designed to be ‘wet’ with a sealed impermeable floor (see 15.2). All fittings must be of a design to suit wheelchair use. It is beneficial if a development contains bathrooms with handed layouts to allow for different abilities.

14.9 General provision for wheelchair users

14.9.2 Dwellings specifically for wheelchair users: The space in the bathroom must allow for someone in a wheelchair to turn through 180^o, i.e. a circular area of 1500mm diameter (see 2.5.1), without being impeded by the door. Except in very large bathrooms this is helped by the door opening outwards, which in any case is preferable to allow access if a person should collapse against it. The plan of the dwelling should ensure that this does not cause a hazard in the hall, particularly in family houses. There should also be space for a helper alongside a wheelchair in the bathroom.

14.10 The use of hoists

14.10.1 Dwellings specifically for wheelchair users: Some people will need to use a ceiling mounted hoist to transfer them to the bath and/ or WC from a bed. To allow for this it should be possible to install a track between the bed position and the bath and WC. The plan of the dwelling, the probable position of a bed and layout of the bathroom should be arranged to allow for this.

14.10 The use of hoists

14.10.2 Dwellings specifically for wheelchair users: With a hoist double doors will be required between the bedroom and the bathroom, with a cut-out at the head of the door to suit the particular track. It is not anticipated that such doors will be installed unless they are needed by an occupant, but they should be allowed for in the initial design. A ‘knock out’ section in the partition is useful. This should be 1200mm in width and 400mm in from the back wall. The track should preferably be straight, though a curved track with a minimum radius of approximately 1000mm is possible.

14.10 The use of hoists

14.10.3 Dwellings specifically for wheelchair users: The installation of a hoist will require a structure designed to take the weight and the roof or upper floor structure above this area should allow for this. The normal ceiling and roof construction in new build housing will usually be of adequate strength, though this must be checked and strengthening added if necessary. Where strengthening is needed it should be extensive enough to accommodate different hoist arrangements as the precise location of the track will depend on the individual needs of the occupant.

14.11 WCs for wheelchair users

14.11.1 Dwellings specifically for wheelchair users: The position of the WC should allow frontal or side transfer with a clear space of at least 750mm on one side. On the other side there should be a wall, capable of taking support rails, at a distance of 450mm from the centre line of the WC or a clear space of 450mm in which a hinged support could be fitted. The distance of the pan from the back wall should be such that it allows the seat of the wheelchair to be positioned adjacent to the seat of the WC to assist transfer. The front of the pan should therefore be at least 750mm from the wall, or from any pipes or ducting less than 500mm above the floor.

14.11 WCs for wheelchair users

14.11.2 Dwellings specifically for wheelchair users: The WC should have a rim height of 420mm – 450mm, any necessary height adjustment to this will usually be by means of different thicknesses of seat. WCs designed with a rim height of 500mm or so are available and may be preferred, particularly where a wheelchair user lives alone or there is a second WC of standard height for use by other members of the family (see also Section 14.17).
