Frequently Asked Questions

What is the weight limit?
The BT-17 has a 100 lb live load capacity do to the amount of fasteners supplied with the unit and based on a retro-fit or over the tile method of installation. The capacity can be substantially increased by installing additional fasteners and/or mounting the unit directly to the face of the substrate.
Can I then use this unit for a footrest?
Yes. We are aware that many clients are installing the BT-17 low for that very purpose. It is best to mount the unit to the substrate first if this is at all an option, otherwise you will need to install 3 additional fasteners (not supplied) that meet or exceed the shear value of the fasteners that we supply. Call for additional details if necessary. You will also need to tile the bottom of the BT-17 when mounted low do to the exposed mortar. This mortar may harbor mildew or mold growth if not covered.
My shelf is high and the bottom is visible. How do I tile it?
The BT-17 was anticipated for a higher mounting location than our bench products. It has therefore been designed with a series of half-inch holes completely perforating the bottom of the unit to make it easy to tile. You install the bottom tiles using standard thin-set or mastic which will adhere via the direct bonding path to the exposed mortar in these holes. Grout and seal as normal.


When applying the mortar to the BT-17, you will need to use a "back-up block" under the unit to keep the mortar from falling through the holes. This can be any piece of scrap wood or a wood float/trowel held in one hand while you fill the unit with the other. Brush off excess mortar from bottom of unit after mortar installation to provide even surface for tile.
