Shower Tray - Timber Floors Assembly information
Assembly information The JACKOBOARD shower unit consists of a floor panel and a drainage system. Both components are coordinated with each other and form one unit. For the floor panel, there are 3 different drainage systems to choose from. 2a 6 1 5 3 4 9 7 8 2b 2c System components Shower element Drain as ordered a. Horizontal drain, 0.85 l/s b.

Planning the Project JACKOBOARD Shower Tray - Timber Floors Before you purchase your JACKOBOARD shower tray consider your desired room layout, the position of the supporting floor joists and the route of your waste pipe. Select a tray from the JACKO- BOARD range which covers your desired wetroom area and also allows you to fit the drain in the space between the floor joists. To fit the drain body under the floor the centre point of the drain must be at least 80mm away from any floor joists. You will need to consider what waterproofing treatment you are going to apply to the walls of your wet area. The joints between the tray and the walls will be protected by special sealing tape but for a totally professional solution the walls should be lined with JACKOBOARD construction boards and the joints between the wall boards protected by sealing tape. Alternatively a waterproof membrane can be applied to the lower walls. You also need to consider how you are going to reinforce the rest of the bathroom floor area prior to tiling. To provide a robust floor surface for tiling the floor should be reinforced, traditionally this has been done by adding a plywood overlay but modern specifications call for purpose made tilebacker boards. By using a JACKOBOARD construction board as reinforcement you get the additional benefits of your wooden subfloor being covered in a waterproof and thermally insulated barrier. The waterproof nature of the JACKOBOARD construction boards, when the joints are sealed with sealing tape, will produce a totally reinforced and waterproof bathroom floor. The thermally insulating properties make this type of bathroom floor ideal for the addition of electrical underfloor heating. The insulating properties will optimise the performance of the UFH which can also be installed over the shower tray to further enhance the wetroom showering experience. If you are going to overboard your existing floor you will need to allow for this slight increase in the finished height of the surrounding floor during installation. Adjust the heights of the reinforcing sub-floor, and the platform that is installed to support the drain body (see Assembly Information) so that the edges of the installed tray finish flush with the rest of your overlayed bathroom floor.

Planning the Project & New Assembly Infomation JACKOBOARD Shower Tray - Timber Floors Remove the floorboards in the area where the shower tray is to be fitted. Construct a platform to support the waste at a depth of 80mm below the bottom surface of the tray. If you are not adding an overlay to the rest of your bathroom floor the top of this platform will be 80mm below the top of the floor joists. If you are adding an overlay reduce this dimension accordingly. Connect the waste to your waste pipe. The supplied waste accommodates a DN 50mm compression fitting but adaptors are included to connect this waste to 2 or 1½ waste pipes by solvent weld. Lay the tray over the drain to ensure that they are correctly aligned. Ensure that all joints are watertight as it will not be possible to return to them once the tray has been installed. Construct a sub-floor between the joists by fixing battens to the sides of the floor joists and filling the spaces between the joists with plywood, nominally 18mm thick. As above, if you are not adding an overlay to the rest of your bathroom floor the top of this sub-floor will be flush with the top of the floor joists. If you are adding an overlay raise up the sub-floor so that the edges of the installed tray finish flush with the rest of your overlayed bathroom floor. The battens and sub-floor must be securely screwed to the floor joists to create a rigid structure. The sub-floor section where the waste is to be fitted needs a 160mm diameter clearance hole cut out for the waste. Check to make sure the shower tray and waste are correctly aligned and adjust as necessary. 4
The sealing washer is inserted into the shower unit. Here, the thin sealing lip lies over the plastic flange and the thick sealing lip under the flange. An appropriate adhesive (e.g. rapid set, flexible tiling adhesive) is applied all over the underside of the shower unit using a notched trowel. The JACKOBOARD shower unit is inserted into the floor opening so that the sealing washer lies centrally on the drain. 5
The drain is then firmly screwed to the shower unit using the ferrule and the 3 threaded screws. The edges of the tray should be checked with a spirit level. For better adhesion, the JACKO- BOARD shower unit should then be evenly weighted. All joints should be sealed using an appropriate waterproofing system of tapes and sealing compound. The insert ring is inserted into the shower panel. 6
The top piece is cut to the desired height according to the thickness of the tiles. The top piece is then inserted into the shower unit. The shower unit is finished and can be tiled. Tip: In principle, all types and sizes of tiles can be used. Special requirements for tiling are only necessary with mosaic tiles < 25 mm. In this case, you should always consult the manufacturer. For shower units that are suitable for wheelchairs the size of tiles have to be 50 x 50 mm.
