Outdoors Shower draining plan

Alon

Planning an outdoor shower and would love some thoughts on plumbing to sewer line.

starting from scratch and currently have about 260mm fall from floor level to sewer line.

Any thoughts ?

A warm welcome to the Bunnings Workshop community and thank you for your question.

Ultimately, the actual plumbing will need to be done by a licensed plumber, but I'm happy to offer assistance with planning.

You will need the shower drain to fall by a ratio of 1:50, 1 being rise and 50 being run. This means your shower pipe can run up to 13m with a fall of 260mm.

If you have some photos of the area, can you upload them so our members can see what we're dealing with? Let me know if you need a hand with uploading images. I'm happy to help if required.

Some basic measurements of the area would also help. If you can jot them down on paper and upload an image, that would also help.

Are there any specific questions outside of this that you have?

If so, please let me know and I'll do my best to offer guidance.

Hi Jacob,

Thank you for your reply.

I have an area mapped out of about 1800mm long by 1000mm wide designated for the shower.

I have dug down a little and discovered a 90mm storm water pipe and a 100mm sewage pipe.

Being a shower it will be connected to sewer.

I have two plans and my sense is that decision will be dictated by the ability to drain the shower (and a sink).

Plan 1.

Pour a slab (to be tiled later) with a grate drain in one end of it, draining to the sewer.

Plan 2.

Raise timber frame and insert a tile able shower base.

The challenge I have is that from the top of the sewer pipe to the top of the slab I only have 260mm clearance.

Having to fit a trap and into that height seem tricky to impossible.

While with a raised timber floor I gain another 300mm clearance making the whole clearance 560mm.

I am uploading a picture of the site here (sewer pipe is on the left).

Your thoughts will be appreciated.

Thank you again Jacob for your reply
