JACKOBOARD® Aqua Flat is a wet room / walk-in shower element which is particularly well suited for use on wooden beam ceilings. Thanks to the extremely low thickness of only 20 mm, Aqua Flat can easily be integrated in the timber framework so that it is installed flush with the wooden floor. Whilst the tray has been specifically designed to create wet rooms and walk in showers in properties with suspended floors, you can also install the system in a solid concrete / screed floor.

The shower base is made from extruded polystyrene foam (XPS) which has been machined to create a fall from the perimeter edges to the drain position. The base has then been covered on both sides with a polymer modified cement coating into which has been bonded a reinforcing fibre glass mesh. This coating provides both excellent point loading resistance and a superb bond for cement based tiled adhesives. Crucially, the whole base is completely waterproof and dimensionally stable - it is not affected by moisture, humidity or movement in the substrate.

It’s important to understand that Jackoboard Aqua Flat wet room bases, in common with other extruded polystyrene bases, are not self-supporting. In order to support the base firmly when creating a level-entry design on a suspended timber floor, a sub-floor must be constructed between the joists. Due to its excellent thermal insulation properties the Jackoboard Aqua Flat is the perfect substrate for the laying of underfloor heating mats, helping to keep the warmth in the room intended.

Important Tiling Information:

• Jackoboard Aqua Flat shower bases are in principle suitable for all types and sizes of ceramic and stone tiles. However, for mosaic tiles less than 25mm square we strongly recommend the application of an epoxy resin grout for the tile joints.
• Tiles must be fixed using cement based single part flexible tile adhesive. Pre-mixed ‘tub’ adhesives must not be used.
• The grout line around the drain grate frame should be sealed with a flexible sanitary sealant (silicone) and not a cement-based grout.
• If showers are to be wheelchair accessible tiles must be a minimum of 50mm square.
• Tiles larger than 150mm square must be cut to follow the valleys of the falls, which always run from the drain position to the corners.

If in doubt about any of the above points, or tiling in general please consult a professional tiler.
