ShuffleDEK® Bases

ARC’s ShuffleDEK brings a whole new concept to curbless, pre-pitched, ready-for-tile shower foundations. This is an ideal structural platform for laying large format tile without the need for valley cuts. Plus, the adjustable drain outlet allows installers to miss joists in most situations. All of this is in a fully integrated package—no need to find a linear drain and match it with some other shower building materials. And no mud to mess with.

The three ShuffleDEK models cover popular shower sizes, and they make it is easy to install units side by side for larger showers. This is true for all ARC shower foundations and has become a popular way to build big showers without the expense and liability of altering joists. This is especially important when working with TJI and truss joists, which cannot be modified to accommodate thick bases for curbless showers (in remodels, TJI and trusses would have to be redesigned and rebuilt at great expense).

Because these bases are so thin, they sit on top of joists and match up well with surrounding tile underlayment. As with all ARC shower bases, the ShuffleDEK series is totally structural with a load capacity of well over 800 lbs. when installed on code-approved joists set 16″ on-center. Additional support requirements are minimal, and most of the time it takes only a few hours to install a base. A drain cover is included with each base, and is meant to be filled with tile.

Install a ShuffleDEK and protect the shower with an ARC waterproofing kit in one day, and begin tiling the next day. Within a week you’ll be enjoying a spectacular curbless shower.
