We have a new shareholder who is proposing to expand his bathroom into an adjoining hallway. He would not move any plumbing or fixtures into that area. He is replacing the tub with a shower, however. The shareholder would be required to add a waterproof membrane to the new area.

We do not have a policy about this, and it has never come up before. I am told "many, many" co-ops prohibit it.

The co-op's architect says that it is up to the Board whether or not to approve it, though he gives details of some risks.

In our 70 year old building, we have had many leaks from bathrooms from plumbing inside the wall and from shareholder installed fixtures which caused damage to apartments below and adjacent.

Curious to know whether other board routinely grant permission to install wet-over-dry conditions? If you have granted permission, have you had shareholders who feel themselves compromised complain?

Let me know of your experiences.

Thanks so much
