    I am building a wood bathtub similiar to this

    http://www.driftwood.ie/stan_rect.html

    The only problem I have so far is that I need a drain with longer treads to be able to fit through the almost 2 inches bottom of the tub. Do people sell such a thing or will I have to come up with a different solution.

    Thanks!

    As a plumber, I can only say that I think it's slightly insane to build a bathtub out of porous materials.

    "301.1.1 Approvals. Unless otherwise provided for in this code, all materials, fixtures, or devices used or entering into the construction of plumbing and drainage systems, or parts thereof, shall be submitted to the Administrative Authority for approval and shall conform to approved applicable standards acceptable to the Administrative Authority, and shall be free from defects. All pipe, fittings, traps, fixtures, material, and devices used in a plumbing system shall be listed or labeled by a listing agency or shall be approved by the Administrative Authority when listing or labeling by a listing agency is not available." - UPC

    As to your immediate problem, the only way I can see to accomplish what you want is to chamfer space for the waste and overflow.

    Yeah I understand the concern. The whole tub is going to be encapsulated in epoxy. After that it should be as porous as a fiberglass tub.

    With the 301.1.1 Approvals... are you saying that the tub since it is a 'device used in a plumbing system' would have to be approved? Or do you mean that any fitting I used for the waste and overflow would have to be UPC approved.

    With chamfering, I was thinking along those lines... but it would be cleaner and easier if I didn't have to do that.

    You could have them made, but the cost would be high. Could be milled out of solid brass, then plated with anything you desire. Or, you could use SS.

    Geberit waste and overflow drains are attached with a bolt that screws down from the top. A longer bolt then the standard is available from the manufacturer. Also, countersinking the drain hole is a good idea. It enhances drainage of the tub, since standing water is unsightly and unsanitary.

    drain

    One company, I believe is is Kallista, makes a plastic tub with an integral overflow so its base is about the same thickness as yours. Contact a bathroom specialty house and see if they can get their drain for your tub.

    As far as I know...
    Unless the fixture is "listed" by an approved listing agency (pre-approved), you would have to get your local plumbing code enforcement agency to issue an approval for it...
    In Phoenix that usually involves hiring an engineering firm here and giving them a couple of tubs for testing (and a few thousand dollars for testing as well)... Upon them issuing a report in favor of the tubs, the code department will give you an "approval" for the one-time use of the tub...

    Or you can make it, install it, and not tell the building department about it.
