The Solid Mount® — If it doesn’t anchor into a stud, it isn’t safe.
Bathroom slips happen fast. When someone grabs a safety bar, it must hold full body weight instantly. But fiberglass shower and tub walls were never engineered to support load. They flex, bow, and crack under stress — making hollow-wall anchors, toggles, compression systems, and suction devices unsafe.
The Solid Mount® fixes this by anchoring the grab bar directly into wall studs — the only structural elements capable of supporting a safety load.
Why The Solid Mount® Is the Only Correct Installation Method
1. Anchors Into Studs — Not Fiberglass
Fiberglass has no structural load rating.
The Solid Mount®:
Transfers all force into studs
Eliminates flexing and cracking
Creates a rigid, permanent backing
This is how grab bars were always meant to be installed.
2. Meets the Intent of ADA, ANSI, UBC/IBC, and ASTM F446
Grab bar safety standards assume the bar is attached to structural backing, not thin fiberglass walls.
ASTM F446 requires grab bars to attach to a substrate capable of supporting 250–300+ lbs.
Fiberglass cannot meet that requirement.
The Solid Mount® creates the structural base that safety codes expect.
3. Works With Any Standard Grab Bar
Any length
Any finish
Any brand
The Solid Mount® provides the stud-anchored support behind it.
4. Permanent, Zero-Maintenance Safety
Unlike suction bars, toggles, or hollow-wall anchors, The Solid Mount®:
Never loosens
Never shifts
Never relies on fiberglass
Lasts the life of the shower
5. Prevents Hidden Fiberglass Damage
Mounting devices that rely on fiberglass cause:
Stress cracks
Moisture penetration
Delamination
Structural weakening
The Solid Mount® removes fiberglass from the load path entirely.
6. Fast Installation With Common Tools
Only a small cutout is needed
Aligns to stud locations
Creates a perfectly flat, secure mounting surface
What Shower Manufacturers Say
Kohler Confirms Fiberglass Alone Cannot Support Grab Bars
“Grab bars may be added only if the unit has age-in-place backers… the wall alone will not be able to provide adequate support.”
— Kohler Co., Official Guidance
“Minimum 1/2″ plywood or 2×4 studding is required to ensure safe mounting support.”
— Kohler Grab Bar Installation Manual
Your system delivers exactly what the industry requires — and what fiberglass showers lack:
real structural support.
Conclusion
The Solid Mount® provides the safety foundation fiberglass showers are missing.
By anchoring directly into studs, it delivers:
Code-aligned support
True load capacity
Compatibility with any grab bar
Permanent, worry-free installation
The Solid Mount® — If it doesn’t anchor into a stud, it isn’t safe.
