plumbing for shower

[pipes]

I am building the shower/bath area on my bus, my question is...can I fit the shower plumbing in a wall framed on 2x2 studs or should I use 2x4 frames? JUST for that wall. TIA. Ken
                         
PS The wall is at crossways to the length of the bus and I am short on space.

I have all my shower plumbing in an inside wall 2X2 >>>Dan

My wall is 3/4 plywood, with 1/2 backer board and tile. I put the valve on the opposite side of the wall in the bathroom (toilet and sink, shower in bedroom). I'll hide it with a cabinet behind toilet. Easy to get to if I ever need to work on it.

The shower head pipe I ran through the ceiling. Had to build a special pipe to come through the ceiling. Found a chrome nipple
to come through the ceiling. I hung the shower head flex hose from that nipple. Working great two years. Still need to tile the ceiling.

I think you should go ahead and purchase the shower valve or at least measure a few at the store so you will know exactly how much clearance you need.  If you do need a thicker wall, it might also be a good place to run your vent stack.  A lot depends on what will be on the other side of the wall, a closet or cabinet would help.  If you use the RV type surface mount valve then the 1-1/2 inch space should be plenty.

I used a Kohler 36" x 36" shower pan and built the 3/4" walls around it, lined with Kemlite.  The shower stall is built 12" out from the wall so I have better head room.  Between the shower stall and the wall I built a linen closet that has the plumbing for the shower also.  Works well since I don't have to rip anything apart if I have to get to the plumbing.  Good Luck, TomC

I put my valve low on the wall with a hand held shower and extra shower head holder and the valve is inside the vanity cabinet out side the shower -- once again easy access

Pipes,

Like Gumpy and maybe beyond what he has done(I don't know his layout) I have every plumbing or panel with a removable closet(clothes, linen, etc..) liner behind it.

The whole shelf/closet slides out(with face frame) after removing a few hidden screws in the upper and lower corners.

If I ever need to get to it I can.

With this setup you can make any adjustment or change you need with out ripping it all apart.

Best of luck

Pipes,
     How are you venting your waste tank system?  I'm using a combined black/gray tank and it is vented through the roof with 2" PVC which is enclosed in my shower end wall with all the rest of the plumbing.  This is my only wall using 2x4 construction, all my other walls are single sheets of 3/4" maple veneer plywood.  My shower/tub enclosure is 'Structoglass' , a fiber reinforced plastic.  The other side of the 2x4 wall has a sheet of 1/4" maple veneer plywood screwed onto the studs (so I can get to the plumbing if needed).You'll need something to mount the valves and shower head to and with a 2x4 wall this is easy with ordinary household plumbing parts.
