Fitting 1200 shower into 1250 space

sirhobo

Hi all
As part of a bathroom refurb I'd like to fit a 1200mm tray and sliding door along the whole width of my bathroom, which is about 1250mm. Shower door can probably extend but tray would fall short

How should i bridge the gap? Builder has suggested applying 2 coats of hardwall render!or sticking the sheet of plasterboard ("dot and dab") to one of the walls. He has quoted £130 for labour and material on top of his original quote for the refurb.

Is the method and quote he's suggesting fair? Are there any (cheaper) alternatives?

Any help would be appreciated!

Put tray in centre. Tiled "shelf" either side of approx 1" width sloping downwards for water run-off. Simples.

Cheers

What keystone says is a possibility, in my experience a 'shelf' always ends up as a weak point and allows water penetration.

I would go with building the wall out with dot and dab. The result is a good fit and no 'shelves' for the water to get into. £130 is fair for the extra works and meterials.

strap the wall with 18x38 timber, plasterboard and sheet membrane

Tiled shelf will become grotty very quickly

At 50mm I'd put up a 38mm batton and screw up Aquapanel - this also gives a handy void in which to run any pipes necessary for the shower valve.

I always preffered "letting" a tray into a wall by 5mm or so, tanking it down tight to the tray then tiling down onto the top edge. It gives a good waterproof seal that way.
