How to install wedi Sanoasa Bench 4

The Sanoasa 4 is a suspended bench that allows a design creating more space

in any shower while adding seating comfort. The Sanoasa 4 is 3 1/8 in. thick

and 47 ¼ in. long. The bench comes pre-sloped on its surfaces so water can

safety run off to the front of the seat where it can move towards the shower

drain instead of causing puddles on the bench tiles.

The Sanoasa 4 can be cut to a shorter length and made to fit between three

shower walls where the bench connects. This bench is ideal for installation

prior to tiling but can also be installed over existing tiled walls. In the latter case,

there is a risk the waterproofing of the walls may be damaged by the Sanoasa

fasteners which are difficult to seal like in most retrofit installations where fas

teners penetrate through tile and waterproofing below the tile. This bench can

carry up to 500 lbs. of load on its surface once tiled without creating a risk for

cracks in grout or tile. The larger and thicker the tile and stone, the more it adds

to stiffness and load capability of this bench. A minimum tile size of 4 inches

should be used and tile should be a minimum of ¼ in. thick.

Cut and dry fit the bench into

the three wall opening in the

shower. Dry fit with the two

L shaped steel profiles loosely

fitted onto the sides of the

bench. Mark the outline of the

bench where it will connect to

the walls so you can see later

where to apply wedi joint seal-

ant.

Determine installation height and apply wedi joint sealant widely over the wall board area where the steel pro-

files will be installed. Press the steel profiles into position. Install steel profiles in level position.

Apply wedi fasteners through the steel profiles and wall boards into to framing spaced 16 in. o.c. apart.

Apply wedi joint sealant widely to all areas that will connect with the bench ( all three walls and o both steel

bracket surfaces). Insert the bench and press into the bed of sealant. Ensure the bench will stay in a tight position

to allow the sealant to bond. Apply a 1/2 inch bead of sealant over and along all transition seams between wall

and bench including on the underside of the bench. Finally, apply wedi mesh tape on all such seams. The mesh

tape is later covered with thinset mortar. Allow wedi joint sealant 24 hours to cure.

After 24 hours, tiling can com-

mence to include the under-

side of the bench.
