Chop the floor up would be the better option and not nearly as scary as it sounds.
Hi I got an existing toilet that runs into the sewer on the ground.I had decided to turn that into a shower.I had approached a few builders/plumbers, i was told we need to include a trap to capture the sewer gases.Among the suggestions i received are
1. To dig into the concrete floor to install the trap
2. Raise the floor by 150mm to install the trap underneath, so that no digging is required.
Has anybody have any experience that you can share? will there be any problems with plumbing compliance if the floor is raised?Is the floor raised high enough to allow installment of the trap for it to work efficiently? Is there problem to remove the shower in the future if i want to convert it back to toilet? what will the ball park figure for this job.
The shower basin is about 900 x 700mm
thank you

Plumbers were around long before Jesus was a carpenter
Hi,
There is a device called a micro trap which may assist. It is mainly used in vanities but there is a shower waste type.

It will mean you don't have to chop such a big cavity around the existing waste drop.
Cheers
If you are already chopping though why not go large and do it properly first off? It may work out cheaper in materials in the long run.
