Designing Kitchens and Bathrooms - framing in basement shower and door

I am installing, attempting that is, a 36 x36 three piece shower stall in our basement. I have demo'd the existing tiled shower, that leaked like a seive, and taken out the water-soaked greenboard along with framing. What I would like to know is what considerations should I take when framing the new shower? I will be using wonder-board for the three-walls, but what about a door? I want glass, but am not sure about the opening measurements and keeping it flush.
Any help is appreciated.
:confused:
Forgot to mention, I do have the base of the new shower stall by Sterling.

Determining where a prefabricated shower stall goes depends on where the shower pan sets. Therefore, you'll probably need to purchase the shower first.


Then measure the base dimensions, transpose its outline onto the subfloor and mark the drain location at the same time.


Assuming the stall's back will be against a wall, cut 2 x 4 bottom plates, position them on the side base marks and anchor them in place with construction adhesive (optional) and screws/nails.


Set vertical end studs on the bottom plates. Butt the end studs of the stall walls to the main wall. Add nailers to the main wall if needed. Fasten the end studs to both the main wall and their bottom plates.

Once the framing is done, you install the shower within the framing. Most shower manufacturers sell compatible door units. You will need a door that will fit the opening of the shower stall that you purchase. To make sure your framing is plumb and square and that your shower is level, you will need a level.
