Dry Deck Solution

Pumped shower drainage solutions for minimal access wet-room applications.

In many contemporary shower and wet-rooms a gravity drain
is not a feasible option. In a loft conversion, where room
height is constrained, or in a basement where the waste
water outlet is higher than the shower gulley, an alternative
system is required.
The Whale Dry-Deck provides the solution. This electrically
powered pump system is quiet, compact and can be
concealed so as not to compromise the room's aesthetics.
It provides a reliable solution requiring no regular maintenance.
