IMPORTANT NOTICE
This document MUST be forwarded to your architect or building

mistakes could be extremely costly.
Pre-Installation Document
Interbath
General Site Requirements.
The wall decoration and floor covering must be complete and finished.
Positioning and fixing the unit.
The Interbath stands on and is secured to the floor. Floors must have sufficient depth in
order to receive 50mm long anchors.
Under-floor heating CANNOT be laid under the bath area.
Adjacent walls need to be plumb, flat and clear of obstructions up to 1220mm above the
floor. Skirting boards may be left in place.
Fig 1
If the unit is to be installed in an alcove or into a corner the side wall/walls will also have
to be clear for a height of 1220mm.
The bath can be fitted as a Corner unit, Peninsular unit or an Island unit.
In all configurations a minimum clearance of 850mm must be left on the door side for
access.
A minimum clearance of 40mm is required against any adjacent walls (WG & LWG) and
fixed appliances (FG) including toilets, radiators, sinks and shower units.
Note: If the bath(corner fitting) is ordered with neatfold stretcher, the gap at
the long side of the bath (LWG) would have to be 65mm.
If a Peninsular or Island layout is required with a neatfold stretcher there
must be enough clearance for the stretcher to swing and fold to the side of the
bath, 400mm minimum on the opposite side to the door.

Fig 2,2a and 2b
When calculating the footprint of the bath use the diagram below and ensure the
clearances are provided at the ends and at the sides.
The red shaded areas must be kept clear of any pipework, wiring or underfloor heating
above and below the floor.
The floor must be strong enough (especially in the foot areas) to carry the weight of the
bath when full and occupied.
NOTE: Floors must be flat and level in the area where the bath is to be installed.
If this is not possible Astor Bannerman MUST be informed prior to installation.

If the water sevice pipes need to be fitted along the wall from a side wall they need to be
kept tight against the wall.
The water service pipes can be offset vertically (V and Vo) providing the centre of the top
pipe is no more than 200mm from the floor.
If the waste is to be fed along the the wall from a side wall it must be kept tight to the
wall and be positioned below the water service pipes.
The 40mm waste pipe can be fed through the wall (WW) or floor (WF) as shown and cut
to the lengths indicated.
