Impey Aqua-Dec Linear 4 Wetroom Floor Former

Product description

The Impey Aqua-Dec Linear 4 is the most versatile former in the Aqua-Dec Linear range. With four gradients and a choice of 600mm or 800mm drain lengths, it adapts easily to walk-in, walk-through, alcove and corner installations.

Its balanced design draws the eye to the linear drain, making it a strong visual feature within the shower area. All Aqua-Dec Linear formers have an average 1 in 40 gradient and a maximum flow rate of 35–40 l/min.

Please note: Impey wetroom floor formers and drains are sold separately — a compatible Impey drain is required to complete the installation.

Add WaterGuard™ tanking

Impey's Lifetime Watertight Guarantee requires the entire wetroom floor to be tanked with Impey WaterGuard™. Choose a WaterGuard kit with your former, sized to the area you're tanking:

5m² floor kit (WG5) — 5m² membrane, 500ml BAL primer, 15m jointing tape, 5 internal corners, 1 external corner, butyl sealant
10m² floor kit (WG10) — 10m² membrane, 500ml BAL primer, 2 x 10m jointing tape, 5 internal corners, 1 external corner, butyl sealant
15m² wall & floor kit (WG15WF) — 5m² + 10m² membrane, 2 x 500ml BAL primer, 15m + 10m jointing tape, 5 internal corners, 1 external corner, 2 x butyl sealant
20m² wall & floor kit (WG20WF) — 2 x 10m² membrane, 2 x 500ml BAL primer, 3 x 10m jointing tape, 5 internal corners, 1 external corner, 2 x butyl sealant

WaterGuard™ is a 1mm self-adhesive tanking and decoupling membrane — no drying time, suitable for large-format tiles up to 30kg/m² and compatible with Aqua-Mat™ underfloor heating. Floor coverage is mandatory for the guarantee; tanking the shower-area walls as well is recommended.

Lead time: 2–5 working days from order.
