J-Sha II Owner's Manual

Framing and Support

The floor structure beneath the bath must be able to support a total weight of bath, water, and bather.

If the subfloor is level, no other preparation is necessary. You can proceed to install the bath. If the subfloor is not level, you MUST level the entire surface prior to installing the bath. Use a floor leveling compound. Do not use mortar, plaster or minimal expansion structural foam to set the bath as this will interfere with bath components on the bottom of the bath. Both sides of a joint or splice of subfloor should be level to each other.

The rim of the bath is not designed to support weight. If finish material is to overlap or contact the bath, the added weight must be fully self-supporting.

The protective film liner inside the bath is used to prevent damage to the finish from shoes, tools, etc. during installation. Before installation, remove liner to inspect for any defects, reapply and do not re- move until final cleanup.
