Construction is expensive and maximising useable space is essential, especially when considering return on investment.

These grate options are suitable for use with different thicknesses of floor tile and stone from as low as 6mm to 20mm and more, assuming a 4mm bed of tile adhesive.
Installation into a suspended timber floor
When it comes to installing a shower drain onto a timber floor, there are a few key considerations to keep in mind. Proper installation is crucial for ensuring the longevity and functionality of the shower drain while also preventing water damage to the timber floor.
Before commencing it is important to confirm that the timber floor/substrate has been installed to BS 5385 - part 3 and is suitable for tiling.
P5 grade/green chipboard is not suitable and should be replaced with external grade plywood of 18mm thickness.
As well as being clean, dry and free from debris the timber floor must be flat, level and load bearing.
We recommend use of the G3 Installation Accessory. When it is used there is no restriction on tile size or thickness. Tiles smaller than 300mm x 300mm, or with a thickness less than 8mm, should not be used unless the sub-floor is constructed and strengthened using the G3 Installation Accessory.
By following these steps, installing a shower drain on a timber floor can be a seamless process that ensures long-term durability and efficient water drainage.
