Shower P Trap clearance

spring3100

Looking to install a Saniflo drain sytem in my basement to service a vanity,lav and stall shower.
Don't wish to cut up the floor,as my roomate (wife) objects.
Need to know,will 2X6's on end with a 3/4 plywood base,then a shower base give me sufficient clearance for the trap w/o any cutting.
I'm getting about 6 1/2 inches necessary by my own eye on a 2 inch trap,not including drain flange.
Any input is greatly appeciated.
Also,is their any plumbing code on height of the shower base above the floor before a step is necessary?Or is the basic rise of a stair my guide.

Have you made any progress on this? I'm working on the same thing in my basement. I ahve the toilet all hooked up now it's onto the shower and was wondering what you did to raise the shower base. 2x6 on it's side, then a 3/4 plywood? Was it enough for the trap & drain? How far away was the unit from the shower?

Any info/experience you had would help me out.

No farther than the required pitch (1/4" /lf?) will allow.
The pedestal is then made high enough to accommodate.

Working on the same type of project, using neoangle shower. Does anyone have photos of their finished risers?

on the ones i have seen installed i think they had to chip a little spot out of the concrete for the trap to sit in for the shower

I've got photos of my project I can email, don't think I can post here, worked great!! Made a riser of 2x6 presure treated & 3/4" plywood. Also chiseled some concrete to make ample room for the P-Trap. I also extended the thru wall pipe (factory told me not to do it) so I could got place pump on opposite side of stud & block walls, after a year still no issues with flushing.

Wound up doing Dri Core flooring,then a 2 by 6 on edge framing,then a 3/4 inch Advantech board as a final footing for the shower base.
Had about 1/2 clearance for the trap,no chipping involved.
About 6 3/4 inch rise on shower stair with finished floor in.
Bonus,able to dovetail a drain for a new utility sink into shower drain going into the Saniflo pump,with bathroom sink going into the other side of the pump,and toilet going into the front of the pump casing.
