Floating Floors
The definition covers a multitude of floor finishes. Typical examples below.
It is imperative that before any work is carried out that an understanding of the floor composition is
carried out.
1. Floating floor fixed to wood 2. Floating floor fixed to wood 3. Floating Floor on cushion material
Supports over concrete Joists
Dependent upon the sub-structure a decision can be made as to whether it is feasible to install a powered bath
with chair. If the bath is a platform bath this is not an issue as there is little or no lateral load. The issue arises
when it is necessary to support the cantilever effect of the chair and patient.
Read below to address the floating floor that affects your installation:
1.
It is feasible to tackle this type of floor in two ways.
a) Remove a section of the surface floor and ‘build up’ from the concrete sub-floor. This can be done by
creating a ‘tray’ and fill this using a concrete mix. Alternatively timber joists can be anchor bolted to the concrete
sub-floor to provide the needed support. The finish should come level with the surface floor.
b) If the void is small it is acceptable to drive through with Rawl/Coach bolts. This may require a small section of
the surface floor being removed and material such as sheet wood inserted to fill the area.
2.
This type of void requires the surface floor removing and Noggins introduced to brace between the Joists.
Particular attention should be made on the area where the foot plate of the bath is to be sited.
3.
Dependent upon the void size it is usually acceptable to remove the material
(often 100mm/4” polystyrene) and back filling with concrete.
Under No Circumstances should fixing be made to the surface floor alone.

¾” BSP Male hot water inlet, 30mm from the floor, against the wall,
200mm from the left hand side of the front (tap end) of the
bath.
¾” BSP Male cold water inlet, 30mm from the floor, against the
wall, 250mm from the left hand side of the front of the bath.
40mm Waste outlet @ 3ltr/Sec, 30mm from the floor, against the
wall, 290mm from the left hand side of the front of the bath.
A 5 Amp IP65 Non Switch Fused Spur, with 2m of 1.5mm 3 core
round cable protected inside plastic conduit to the bath within
200mm of the tap end of the bath, positioning and specification
to be in accordance with current IEE regulations.
An additional power supply will be required if a spa is fitted.
See below diagram for position reference.
Picture for visual reference only
DIMENSIONS TO BE TAKEN FROM THIS Minimum distance between the walls and baths bath
sides is 150mm.
When deciding on the position of the bath there are a
number of points that should be considered.
1. Hoist and wheel chair access
2. Access for installation and service
3. Opening doors
4. Distance from walls and other objects
5. Manoeuvring the transfer trolley
6. Seat traverse
7. Under floor heating, pipe work and cables.
The floor directly under the bath and transfer
area must be a solid and even surface.
Particular attention should be paid to the shaded
area on the plan which needs to be drilled to a
depth of 100mm for fixing points and must be of
solid construction with no buried services.
Electrical connection & Earth bonding.
A 30mA RCCD is required in compliance with the current IEE regulation. This should be located just outside
the bathroom or on the consumer unit covering that area of the building.
10mm Earth bonding and a minimum of 4mm cross bonding is to be fitted and tested for continuity in
accordance with IEE regulations.

The bath includes a type 3 Heat guard Thermostatic mixing valve which has been manufactured to
NHS model engineering specification D08 and approved under the TMV3 scheme.
Please read the following which outlines how a TMV3 may affect the use of your bath.
The working parameters of the TMV3 require a water pressure of 1-5 bars with a maximum pressure loss no
greater than 10:1 between hot and cold feeds.
It is important to note that a pressure difference between hot and cold pipes will have a great effect on the
time it takes to fill a bath.
i.e.
Hot water 1.4 bar and cold water 2.4 bar = approx. 9min to fill with 180 litres.
Hot water 2.2 bar and cold water 2.2 bar = approx. 5min to fill with 180 litres.
If in doubt a pressure test should be carried out prior to installation of the bath and if required a booster pump
or pressure reducing valve fitted.
