Frequently Asked Questions

How much weight can floating shelves hold?

Weight capacity depends on wall type and fixings. Solid walls can support 30-50kg per shelf, while hollow walls typically support 10-25kg per shelf with appropriate cavity fixings.

Can I install floating shelves on any wall?

Most walls can support floating shelves, but plasterboard-only walls have limited capacity. Always use appropriate fixings for your specific wall construction.

How far apart should floating shelves be?

Spacing depends on usage: 300-400mm for books, 400-600mm for display items, and 250-400mm for bathroom storage. Consider both function and appearance.

Do I need special tools to install floating shelves?

Basic DIY tools suffice: drill, drill bits, spirit level, measuring tape, and screwdrivers. A stud detector is helpful for hollow wall installations.

How do I make sure floating shelves are level?

Use a quality spirit level for marking and installation. Mark the first bracket position, then use the level to mark all subsequent positions accurately.

Can floating shelves be removed easily?

Most floating shelves can be removed, though some systems are easier than others. French cleat systems offer the easiest removal and repositioning.

What's the best height for floating shelves?

Standard height is 1500-1800mm for display shelves, but consider the room function: kitchen shelves 500-700mm above counters, bathroom shelves 1200-1600mm from floor.

Should I hire a professional for floating shelf installation?

Consider professionals for heavy-duty installations, complex wall types, or when installing multiple shelves. Simple, light-duty installations are suitable for competent DIYers.
