I'm getting ready to renovate my home and want to start with my two bathrooms. Both had tile tub and shower enclosures that eventually allowed water to penetrate through them. Both baths share a common wall that is used to bring up plumbing to the showers and bathtub.

The problem is that this water seeped under the wall and has damaged the floor sub flooring in the adjacent living room causing the hardwood flooring to buckle. Worse yet, it has caused the floor under an entertainment unit to sag to the point where the enterainment unit is no longer level.

I've examined the flooring and see that the plywood should be replaced. The joists show no evidence of rot and seem strong when tapped with a hammer.

Problem is that I don't know where to start. Should I remove the wall and rebuild the floors into the baths, or should I simply box the areas and drop the plywood on top, leaving the wall intact? There is no damage to the framing or the wallboard on the living room side. Alternately, should I call in a pro?

Hi patv,

1) If you know where the 'problems' are, you need to start gutting. 2) If you DON'T know where the problems are, have a Pro do it.

WHat I'm really saying is that I wouldn't go 'blindly' gutting anything UNLESS I was 'pretty darn sure' of what needed to be fixed. Sure, you could go 1 step at a time in order to see where the problem(s) are.

If you want to be safe, have a Pro do the demo and repair work. You can do the 'finish' work. HOWEVER, do your homework about finish work BEFORE you buy anything! For example, you want to be sure you have an adequate sub-floor in the bathroom. To know what you should do, a decent Kitchen and Bath book from Reader's Digest or Time/Life or somewhere, should help. (Inquire into them if you can to see if they talk about remodeling And 'gutting', if you know what I mean.) YOu can go to a bookstore too and thumb through some books.

My best to ya and hope this helps.

Thanks Jay J. I know where the problems are, but I'm not really sure what the correct, code compliant repairs are.

I corrected the water seepage through some temporary means, until I can tear down the tile and wallboards, and replace them with tub and shower enclosures. One bathroom already has the wall open and I can see that all structural lumber is clean. It was only the plywood that absorbed the water.

The damaged subfloor is running under the wall. Fortunately, the wall is a divider and not load bearing. However, the wall runs parallel to the joists. Since the subfloor is damaged, there isn't any real support now except for the sole plates in the framing. If I simply box the area, which I have done in another house, I would be concerned that the wall has no support. I would want to add some sort of structural support for the wall, possibly in the form of new joist added under it.

So, I will follow your advice, and contact a pro. I contacted a floor refinisher that came recommended to me, and he gave me the name of the person he uses for structural repairs and installation. I'll give him a call and see what he says.
