Originally patented in 1997, The Solid Mount® was engineered to solve the structural gap between fiberglass shower walls and the wood studs behind them.
Unlike surface-mounted anchors, it transfers grab bar loads directly into the wall framing — not the fiberglass panel.
Designed specifically for fiberglass tubs and showers. Proudly made in the USA.
Look for the distinctive ‘Heart of The Solid Mount®’ mounting configuration
Fiberglass shower and tub walls are thin composite panels — not structural supports for body weight.
Many mounting methods rely on the fiberglass surface itself, including:
Suction cups
Toggle anchors
Hollow-wall anchors
Compression fittings
Without structural backing, fiberglass can flex, compress, or crack under load.
For a grab bar to function as a safety device, the load must transfer into the wall framing — anchored directly into the wood studs behind the enclosure, never the fiberglass panel.
When installing grab bars in fiberglass showers, the mounting method determines whether load is transferred into the structural framing of the wall — or into the fiberglass panel itself.
| Feature | Hollow-Wall Anchor | Stud-Mounted System (The Solid Mount®) |
|---|---|---|
| Anchors into wood stud | ❌ No | ✔ Yes |
| Relies on fiberglass strength | ✔ Yes | ❌ No |
| Transfers load into wall framing | ❌ No | ✔ Yes |
| Designed for fiberglass cavity gap | ❌ No | ✔ Yes |
| Structural load path | Surface compression | Direct stud transfer |
| In fiberglass enclosures, structural anchoring into wall studs is the only method that transfers load into the framing of the home. | ||
Manufacturer installation instructions commonly specify that grab bars must be secured into wall studs or approved structural backing.

The Solid Mount® is engineered to secure grab bars directly into the structural wood studs behind fiberglass shower and tub enclosures.
Rather than relying on compression against the fiberglass panel, the system bridges the cavity between the enclosure and the framing, allowing load to be transferred into the structure of the home.
This creates a stable, permanent mounting point designed specifically for fiberglass installations.
