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.

Floating floor fixed to wood

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.
Minimum Dimensions for Access: Doorway: -
825mm. Corridor: - 825mm
Consideration must be allowed to manoeuvre the bath
around hallways etc.
