Finishing bath and shower modules


When finishing one piece bath and or shower units there are two schools of thought.
#1-Run the rock only up to the edge of the mounting flange and prefill with setting type compound (hot mudd) then flat tape and finish with "green lid".

#2-Fur out the wall so drywall factory tapered edge sets squarely over the flange and screw heads within a maxium 1/4" of the unit and fill with 100% silicone mold resistant caulk.

Which method is most common in your neck of the woods? And why would you favor one over the other?

In So.Cal #1 is the most common or in other words why do we do method #1 when the factory recommends #2

You are correct but, the silicon I would prefer paintable silicon which is not 100 percent silicon. The most common here is cutting the rock back to butt up against the shower flange. You use to see contractors shimming or furring out the walls but they got to lazy and too cheap to do it any more, besides if there is a prehung door on where the rock is shimmed out it messes with their jamb thickness.

Re: Finishing bath and shower modules


Ok I will chime in here, method #1 is most prevalent here in my area and is the method I prefer. Why? I have seen method #2 and never thought the board appeared to be sitting "flat" I always prefill with Durabond 90 (and here's the part that will get me in trouble lol) lay on mesh tape into the still wet durabond, then skim coat with another layer of DB 90 .then I finish as usual with either AP or plus3.
Now, to the naysayers, I have never had a call back for my tub/showers.
Also, just so I am clear where I stand, besides for repairs that is the only place I use mesh and of course you only use hot mud when using mesh.
Mesh and paper both have their place in this trade IMO

Re: Finishing bath and shower modules


Ok, to be blunt, and not meant to offend anyone, filling the recess with any type of mud is completely WRONG! What will happen is that WHEN the caulking around the tub unit fails, which it will, water will wick up in the wall.

Method number 2 is the correct method.

Re: Finishing bath and shower modules


A shim job do work well,,but sometimes the rock is even -level with the top of shower-tubs [the cheap ones] sometimes even overlap .

Don't stand there and look those shower-tubs too long.
Or you will scratch It..

Re: Finishing bath and shower modules


heres a cool little tip on some of them tubs.

If the tub has a short wall at the end of it, ya know, where it takes a 4" rip and two beads.

Cut the rip 41/4", eyeball the rip on the end of the wall, so that the edge of it is even with the flange of the IMPROPERLY installed tub. Then put the 1 1/2 rip against the tub, draw it tight with nails. Makes a perfect 90 degree, where otherwise you get that UGLY off angle twist.

I feel mesh and hot mud are 10 times stronger than paper, and I guess because I was taught that way, been doing it for years.
I can tell from reading your posts over the last several months you, Capt, are way more experienced than I am and your one of many that I highly respect on DWT.
So I will leave my response at that and not run the risk of sounding like a idiot lol
