Minimum dimension from top of shower drain to bottom of P trap

[JP Reuer]

I'm installing a new bathroom over an existing concrete slab with radiant heat, and do not want to cut the slab for the new plumbing lines. (I plan to run drain lines over a few feet to en existing vertical chase / slab penetration).

For planning purposes, what is the minimum dimension from top of shower drain to bottom of its P trap?

Thanks!

It would depend on how deep your sewer line is under the slab. I just rebuilt my shower drain and it measured about 15''.

Also depends on if you get an above floor rough in shower or a regular one.

Thanks - I'm thinking an above floor rough-in. Any idea on how much height I need to plan for between the top of existing floor and the new shower drain?

Find out what you want to buy and pull up the specs.

actually depends on how it is plumbed
