I read that a dap out (14" x 14" opening) in the foundation slab
Is used to access the tub trap. Is a dap out area also used
For the shower trap ? Thanks, Lee

The 14 X 14 inch enclosure is for a access panel in the wall behind the tub.
The average tub dap out is 12 X 12" square in the slab and the tub trap sets underground with a stub-up raising to connect the tub drain and overflow.
Have a great weekend. Tom

No there is not usually an area to access a shower drain unless you have a raised foundation and you can crawl under the house to get to it.

I installed a shower enclosure and base unit on a slab
About 3 years ago, and rememember having problems
With the 2" drain pipe being flush with the slab floor.
I don't exactly recall the particulars, but I had to chiesel
Out some of the concrete around the drain pipe to get
The shower base set. Should there be a recessed area in
Slab at the drain pipe or is the slab floor always flush with
The drain pipe ?

Lee, Darrel is bang on. I should have mentioned in my last post that we leave a dap out for tubs but for a shower we install a trap under the slab with a raiser coming out of the trap to about 3" above the slab. We never leave a shower raiser level with the cement. We leave enough raiser exposed so the we can pick up the shower drain. Regards, Tom
