Hey Markee,
Not inside, just alongside. Tub exterior edge is flush with slab edge, so am hoping to come straight up out of the ground alongside slab edge, and then right angle into the tub at the tub's pre drilled side inlet for clean as possible.
I have to rebury the trench before the tub arrives, so all I really need to know is how far back that side hole on the tub is from the front of the tub (I'm assuming its the same as the 545 but am not certain).
Thx!
