Tiling Onto Hardboard

Hardboard is really a little too flimsy to tile onto. You'd be much better off using 1/2" ply or MDF.

Thanks for the reply but in this situation ( 4 foot long x 3 1/2" wide strip) I think 1/2" ply or MDF would be overkill. I can go purchase 3 or

I wouldn't in general as it's too bendy under load and it's too likely to warp into a curve. It's not the exposure to water from being in a bathroom, it's just the mechanical flimsiness. I'd use Viroc Versapanel (because my local shop has it) or one of the similar cement- based boards.

For something this size though, I can't see a problem with hardboard. After all, it's not plasterboard - which really would be too flimsy and damp-sensitive.

If your 4 x 1 uprights cover the whole 4ft length, you'll have 2 edges to stick the tiles to. You may not need anything across the top, but it's a nice little ledge for glass bottles and things, which will crack the tiles if dropped. Hardboard is really no good at all but I suppose you could glue 3 or 4 pieces together if it's quicker than going to B&Q

I would normally fake that up from scarp cip.pluyy, bits of old kitchen units and spare bits of MDF, or even plasterboard.

Hardboard never. No stiffness. The tiles will crack off.

Normaly I would never use hard board, but in this instance it is such a narrow strip and it sound like it will be quite stiff so I think you would get away with it and yes you could use a no nails glue.
