The shower recess that was never formed

In short: A set down missing from a Leppington slab where the bathroom was going.

What a recess is

A set down formed in the slab so the finished wet area floor can fall to the waste without stepping up into the room.

A shower recess not formed before a Leppington pour, plus recesses needing extension and trimming on other jobs.

Creating it afterwards means saw cutting a finished structural slab, with dust, reinforcement you must not hit and an engineer's view on the result.

The formwork carpenter works from a plan and a recess is a small detail on a large drawing.

Pre-pour, alongside cover, mesh and the vapour barrier.

Questions Leppington owners ask about this

Whose mistake is it?

The builder's to fix, as the party setting out to the plan. Catching it before the pour makes it a non issue.

Could the plumber adjust instead?

Within limits, but a shower that steps up into the room is a compromise you did not choose.

Is a recess always needed?

That turns on the design and how the waterproofing is detailed. What matters is that built matches drawn.

What other formwork items get overlooked?

Incomplete edges and bracing, which we have recorded on Leppington pours as well.
