Bathroom Remodel
 
We gutted our bathroom and have put in a fiberglass one piece tub shower through the outside of the house. So this part is done but I read somewhere
that you should not have the waterproof wall board behind the tub is this correct?

For the tile floor do we put the waterproof drywall up first and leave a space above the subfloor and tile so that it does not touch or do we put the wallboard
up first going all the way to the subfloor and then put the backer board down and tile so that the backer board and tile butt up against the drywall?

You asked a lot of questions----

The one piece tub---is that installed correctly? insulated behind and fastened to the studs?
Did you put any masons mortar under the bottom to help prevent flexing? Not all makers require that----

Why water resistant dry wall? A nice touch---but not required----install the drywall before you rock and tile the floor--

Keep it up about 1/2" to 3/4" from the wood subfloor---

Then install the 1/4" backer board--set into a bed of fresh thinset and nailed or screwed---

Thank you Mike for the reply and yes the tub is fastened but no mortar it was not required in the directions.

I was told that for the bathroom you needed water resistant drywall. Why can't the waterproof drywall touch the tile?

There is no need to cut the drywall tight to the floor----it is simpler to install---if and water gets on the subfloor,it will not wick into the cut edge of the board----

After the tile backer and tile is installed ---the gap will be covered by the tile--

A base board or ceramic base will also be installed which will hide any gap that remains---

Okay I get it now I didn't think about the cut edge makes sense thanks again for
your help and clearing that question up.

did you put an air barrier and insulation between the back of the tub and the exterior wall? see this link http://publicecodes.cyberregs.com/ic...9_4_sec002.htm

check out Section 402.4 #8. check with your local building code to determine your code requirements. not having this can lead to condensation on the backside of the tub and rot over time.

just my humble thoughts ...... good luck!
