MODULAR CONCRETE BATHROOM PODS

Well-executed construction where every detail has been considered

 

CONSTRUCTION DESCRIPTION:

 

FLOOR ELEMENT

Made of reinforced concrete, 2,400 kg/m³. The floor element is moulded with an upstand/hulk.

The normal floor thickness is 95 mm + 35 mm insulation excluding floor covering.

Drainage and heating installations are moulded in.

Floor drains will almost always build down below the bottom edge of the base.

Detail around doorstep/ transition to adjacent floor is customised according to customer requirements.

The floor element is made with a moulded-in slope of 1:100, however, in the shower area a slope of 1:50 towards the floor drain. Bath elements are supplied with a 35 mm drop to the drain.

Any recess for the bathroom pod is moulded into the element.

Top side of the floor element: Smooth moulded side. Underside: Levelled concrete with a tolerance of +- 5 mm.

 

WALL ELEMENTS

Made of cross-reinforced lightweight concrete, 1,650 kg/m³.

If the weight of the pod is to be reduced, special lightweight concrete, 1200 kg/m³, can be used. This is at an additional cost.

Wall thicknesses: 60 mm standard. 80 mm where e.g. kitchens are to be suspended or where there are sound/fire requirements. The wall thickness can be increased according to customer choice if special conditions require it.

The wall elements are moulded vertically with 2 form sides. Moulding is done so that 2 walls and the ceiling are always moulded together. The remaining 2 walls are also moulded as one. Visible external corners are moulded as far as possible without element joints. The wall elements are made with a “toe” on the outside, so that the outside wall is finished below the finished floor of the building.

For visible walls, the walls are moulded with raised edges at a height that ends the element 20 mm from the lower edge of the concrete deck in the building.

Exterior visible walls are fully levelled and filled at the factory.

Interior walls are tiled or filled, covered with felt and painted in gloss level 20.

Window reveals: Window reveals can be attached to wall elements so that the interior addition in the window reveal can be tiled or covered with felt at the factory. At an additional cost.

 

SOUND INSULATION

60 mm sound reduction 36 Db

80 mm sound reduction 38 Db

 

FIRE CONDITIONS

El 60 A2-s,d0

 

CEILING ELEMENT

Made of cross-reinforced pumice concrete, 1,650 kg/m³
If you wish to reduce the weight of the bathroom pod, special lightweight concrete, 1200 kg/m³, can be used. This is at an additional cost.

 

CEILING THICKNESS

60 mm standard

Ceiling thickness can be increased according to customer request if special conditions require it

The underside of the ceiling is smooth form side, which is fully filled and painted in white, NCS SO-500N.

 

WET ROOM MEMBRANE

A wet room membrane sealing system made by PCI type Seccoral 2K is used.

The wet room membrane is made according to. SBU instruction 252

 

ELECTRICAL INSTALLATIONS

Empty pipes and electrical boxes are embedded in walls

Make LK is used. There is a choice between the manufacturer’s various models, e.g. Fuga, Opus, etc.

Unless otherwise specified, all empty pipe installations are Ø 20 mm flex pipes

As a minimum, equipotential bonding is carried out from the main reinforcement of the pod and ventilation spigots

 

Basic connection options

Light:

Connected in junction box in service shaft

Connected via coiled 3 x 1.5 mm² cable with length reaching the control panel

Connected to the external switch box for light in the bathroom through 2 empty pipes routed to the floor

 

Washer/dryer:

The two phases are connected in a junction box in the service shaft

Connected via coiled 5 x 2.5 m² or 5×1.5m2 mm cable with length reaching to the switchboard

Potential equalisation:

Potential equalisation of the main reinforcement in the bathroom floor and ventilation duct via a socket in the bathroom

 

The electrical installation is carried out in accordance with DS/HD60364 and BEK1082.

Electrical installations are tested according to. KS-manual Appendix D

 

DOMESTIC WATER INSTALLATIONS

Domestic water installations are made of 16 mm pex pipes, routed in a pipe-in-pipe system.

Junction boxes are moulded into the wall elements for the tap points

The system is VA approved

The water installations are routed vertically up the walls of the bathroom pod above the pod ceiling to the service shaft

The water installation is terminated either with 2 distribution pipes with ¾” union in the service shaft or with a rolled-up overlength on pex pipes

An additional connection point for water connection to the kitchen sink can be provided on the pod’s distribution pipe

Water installation is leak tested according to KS-manual appendix E1. KS-manual appendix E1

 

DRAIN INSTALLATIONS

Internal drain installations are routed in welded PEH pipes, brand Geberit

Standard floor drains are ABS floor drains with stainless steel grates, make Unidrain.

Alternatively, a corner drain made by JAFO or Blücher.

If possible, the drain installation should be terminated in a service shaft. Drain installations from floor drains, washbasin and washing machine are joined together as far as possible into one pipe with a 50/75 mm PEH drain pipe. Drains from the toilet are dimension 110 mm PEH.

Drain pipes internal to the bathroom floor are laid with a 16‰ fall according to the DIF standard for drain installations. DIF standard for drain installations, drain installations in prefabricated elements

All materials are CE type-approved

Drain installation is leak tested according to KS-manual appendix E3. KS-manual appendix E3

 

HEATING INSTALLATIONS

Water-based underfloor heating is the normal standard solution, realised in 15 mm pex pipes

The underfloor heating is regulated with a return valve controlled by a thermostatic element. The underfloor heating is terminated in the service shaft, with the necessary excess pipe length so that the pipes can reach the apartment’s heat distribution pipe without joints

The underfloor heating installation can alternatively be supplied as a pipe system with room thermostat control

The Pex underfloor heating pipes are fixed to the top reinforcement mesh on the underside of the reinforcement mesh with a covering concrete layer of approx. 50 mm and with a distance of 200 mm between the heating loops

Electric underfloor heating can be provided if desired

The heating installation is leak tested according to KS-manual appendix E2. KS-manual appendix E2

 

VENTILATION

Bathrooms are normally supplied with an extraction valve for central extraction. This is terminated with a Ø 100 mm spigot in the service shaft.

The valve is placed in the ceiling and routed to the shaft via an attached ventilation pipe. A silencer can be fitted if necessary and there is sufficient space above the bathroom ceiling. 

An electric fan can be supplied if required.

 

DOOR

The bathroom pod is not normally supplied with door leaf and frame fitted.

Plastic screw blocks are moulded into the door hole for installation of the door frame on site. Please refer to the installation instructions for bathroom pods for this installation.

 

LEVELLING COMPOUND/EXTERNAL CORNERS

On corners where there is adjacent drywall, the wall of the bathroom pod is provided with a continuous 2 x 40 mm filler bevel, where reinforcing fabric over the wall joint can be installed and levelled.

External visible corners are provided with a steel putty edge to ensure straightness of the corners.

 

PACKAGING

The bathroom pod is delivered with a plywood panel in front of the door hole. The door plate is hinged and serves as a temporary door. The door plate is closed with a padlock. The door panel is split in two so that a lower part of approx. 200 mm in height and the full width of the panel can be removed without removing the rest of the door panel. The purpose of this is so that the carcass installer can check the drop in the bathroom door opening after installation and so that the carpenter can check the floor height of the bathroom and coordinate this with his floor heights when laying wooden floors outside the bathroom.

If a door is supplied, it is equipped with a padlock system that prevents access to the bathroom during the construction period.

Bathing pods are supplied with 4 wooden blocks 150 x 150 x 150 mm attached to the underside of the pod base. These are removed immediately before installation.

 

LIFTING DEVICE

The bathroom pod is equipped with 4 lifting points. These consist of a 20 mm wire strap attached to the main reinforcement of the walls. During installation, the installation contractor screws the supplied wire straps to the insert and the pod is ready to be hoisted into place in the building.

For more information, please refer to Badelement’s detailed installation instructions.

 

RECESSES FOR DRAIN INSTALLATIONS

Depending on the floor height of the building, it may be necessary to make recesses for parts of the drain installation in the upper side of the concrete deck under the bathroom pod. In each individual case, the height of the concrete deck at the location of the bathroom pod must be assessed to determine whether a recess is necessary.

As a general rule, when using our standard floor drains from Jafo, a recess is not necessary if the floor construction is 180 mm and for drain channels from Unidrain or Blücher 210 mm. Unidrain or Blücher 210 mm. However, always contact us to determine the size of the recesses.

Factors such as the length of the connecting drainpipes can also have a significant influence. It is recommended to contact us on a case-by-case basis.
