Sticky pad shower riser

[tomsim]

Are the sticky pad shower riser kits ok? Would it be best of stickall ing the pads on to the tray or as they sticky enough?

Never use them, IMO they're crap, replaced a number of them, as over time they've moved and broke the tray seal.

Better to build a solid wooden plinth with a min 18mm WBP/OSB3 top on it.

Excellent thanks you I will build a base with 4x2 and 18mm wbp ply. Do I need to seal the ply before I put a weak mix of sand and cement on to bed down onto?

Anything "sticky pad" is destined to fail.

If it's proper WBP plywood you are using then no, nothing would really be needed.

If it was me tho, I would be tanking the space which includes tanking the plinth top as well as the walls.

Thanks. When building the base with 4x2 timbers would I be ok to pack the 4x2 with 1 or 2mm plastic Packers if needs leveling.

Would rapid set sand and cement be ok. If mixed at a 5 to 1 ratio.

I never use sand and cement ... others swear by it ..... horses for courses. Rapid set, need to be quick with the leveling.

I use a silicon adhesive on lower sections and HQ sealant on others and finishing.

Thanks would slightly packing the 4x2 be an option?

When it comes to leveling then yes you can use packers, I usually use hardboard cut to the same width and length as the wood, just don't leave any gaps where the top could flex. Remember, level as close as possible towards the waste, an odd mill out isn't then end of the world.
