Floor Construction
For bathroom pods with walls made of lightweight concrete and walls constructed from fiber gypsum and steel profiles:
Constructed in reinforced concrete (C30/37), approximately 2350 kg/m³. The floor element is cast with an upstand.
Floor thickness is 100 mm, including flooring but excluding insulation.
Embedded drainage and heating installations.
Floor drains are generally positioned below the bottom edge of the base.
Door threshold/transition details to adjacent flooring are executed according to Nordic Offsite standards.
The floor element is cast with a built-in slope, with a minimum gradient of 30 mm towards the drain.
Any recess for a shower niche is cast into the element.
The floor element can be insulated according to individual project requirements.
Wall Construction
For bathroom pods with lightweight concrete walls:
Constructed with reinforced lightweight concrete (LC20/22), weighing approximately 1600-1800 kg/m³.
Standard wall thickness is 60 mm. The thickness can be increased to 80 mm or 100 mm where kitchen units are to be mounted or where sound or fire protection requirements apply.
Wall elements are cast individually as full walls and joined together.
Visible walls can be finished 20 mm above the lower edge of the building’s concrete slab. External visible walls are skimmed and finished at the factory with plaster corner profiles. These additions increase the total wall thickness. External walls must be cleaned on-site, reinforced with mesh at the joints, and fully plastered by another contractor. The bottom edge of the walls stops 20 mm above the finished floor.
Internal walls are either tiled or fully skimmed, covered with a fiber lining, and painted white with a gloss level of 20.
The bathroom pod is delivered with two mounting rails installed in the service shaft.
For bathroom pods with fiber gypsum and steel profile walls:
Constructed with 15 mm fiber gypsum panels on the interior side, supported by 75 mm steel profiles spaced at 300 mm intervals.
Wall thickness is 90 mm.
Internal walls are either tiled or fully skimmed, covered with a fiber lining, and painted white with a gloss level of 20.
The bathroom pod is delivered with two mounting rails installed in the service shaft.
Ceiling Construction
For bathroom pods with lightweight concrete ceilings:
Constructed from reinforced lightweight concrete (LC20/22), weighing approximately 1600-1800 kg/m³.
Ceiling thickness is 60 mm.
The underside of the ceiling is a smooth cast surface, fully skimmed, and painted white with a gloss level of 20.
For bathroom pods with fiber gypsum ceilings:
Constructed using 75 mm steel profiles with 15 mm fiber gypsum on the interior side.
Ceiling thickness is 90 mm.
The underside of the ceiling consists of raw fiber gypsum, fully skimmed, and painted white with a gloss level of 20.
Acoustic Performance
Standard bathroom pod (60 mm wall):
Airborne sound insulation calculation: 62 dB.
Requirement under UK Building Regulations: ≥55 dB.
Compliance with UK regulations: Yes.
Impact sound insulation calculation:
Calculation: ≤40 dB.
Requirement under UK Building Regulations: ≤58 dB.
Compliance with UK regulations: Yes.
Fire Protection
EI 60 A2-s, d0 can be achieved with an 80 mm lightweight concrete wall.
Waterproofing Membrane
A waterproof membrane sealing system is used.
Sealant and Mortar Joints
Mortar joints are applied between wall and floor tiles.
Acrylic sealant is used between the ceiling and walls.
A 6-10 mm slanted silicone seal is applied with backstop between the floor/skirting and wall tiles.
Electrical Installations
Electrical boxes are embedded in lightweight concrete walls or installed within fiber gypsum panels.
Primary manufacturer used is LK, with options including Fuga and Opus models.
Conduits are embedded in lightweight concrete walls or installed behind fiber gypsum panels.
Conduits are either Ø16 mm or Ø20 mm plastic pipes.
Basic lighting connections:
Connected via external membrane junction box in the shaft.
Connected to an external switch box for bathroom lighting via two conduits running to the floor.
General Standards and Compliance
Unless otherwise specified, all production work is performed according to:
Industry-standard tolerances agreed upon within the UK construction sector.
British Standards (BS) for plumbing, electrical, and structural installations.
UK Building Regulations and relevant compliance documents.
Relevant manufacturer specifications and certification requirements.
Reference Pod
The first bathroom pod in production is fast-tracked and used as a reference unit. Inspection can be arranged with the project manager from Nordic Offsite.
