I need to incorporate some steps into one corner and I would like to do this using as little concrete as possible and take up as little space as possible whilst providing a step deep enough to sit on in reasonable comfort . The depth from coping stone to floor is 1.5m (5ft) which from my reckoning equates to quite a lot of steps and a lot of concrete, as I think it is better to fill with concrete rather than sand.
I figured to keep things simple I would just put the steps straight across the corner, rather than curve them.
Can anyone help me work out what would be the minimum amount of steps that I would need and what would be the best configuration of dimensions. I think the bottom step can be very tall as I have seen a pic of a pool with an extra mini step to one side of the bottom step.
Also does anyone know if there are any issues with using such a large body of concrete ie expansion etc (My mix has no large aggregates and is one part cement to 2 parts sand by weight with minimal water). And is reinforcement just below the surface of the steps sufficient or are there other considerations regarding the large body of 'concrete'?
