My't building is west face and the drainage/plumbing pipes needs to be enclosed and not to be seen outside the building.
as the pipes are planned to be on North-west side and staircase also will be on north-west side. Need to ensure that stair case

So, enclose I have been given three options.

a. One is Duct. - which will be very costly and i don't prefer as there is no ventilation.
b. Niche - A small opening in concrete slab similar to skylight, are there any ready made boxes available?
c. Direct drainage pipes through the slab. I don like this either.

So, can we have Niche of (1*2) in a concrete slab so, plumbing pipes can go through them.
Pls share your experiences.

Venky

Venky,

Generally these things are done with core-cutting machine later during plumbing process.

We didn't leave any opening in the slab during construction. Check with your engineer and confirm if this is needed

My contractor provided simple solution. He told me that it can be done by providing a non-concrete block/area which is similar to sump opening.
