With a solid floor or under-boarding the deck provides the perfect, stable surface for tiling over with large or small ceramic tiles. (Other kit options available for vinyl coverings)

Tanking for Piece of Mind - Guaranteed

The DIY Wetroom tanking compound and joint reinforcement completes the most reliable wetroom system available. When installed to the detailed instructions, the DIY wetroom kit has a "life of tiling" guarantee.

The two part design allows fitting to the waste pipe (50mm or 40mm) prior to the deck installation then the top part screws in and seals to the square drain plate pre-fitted to the deck.
