    Many thanks for your help UB, anything else comes to mind, please post again.
  • Tar I will.
    I would still say upsize that waste to 50mm if you can but so long as both aren't used at the sametime it'll be ok.
    Good luck

    No, I don't know it's going to gurgle, it's just that I'm fitting a new shower in and repositioning/replacing the bath to the existing waste underfloor, and want to avoid the problem rather than fix it afterwards.

    It will gurgle, the plug of water from the bath flowing down the pipe causes a partial vacuum behind which will pull air in through the shower trap giving you the gurgle. Fitting an air admittance valve breaks the pull and stops the noise.

    No, because in my first post I said I'll have the shower waste going down via the left side of tee, and the bath waste from the right side. In other words, the tee will be that way up, as the shape of a 'T'. Neither waste will actually pass the other trap.

    Makes no difference, because as I said in my post, the bath waste will induce a partial vacuum as it discharges and this will pull air through the other trap. I did not spend 55 years as a plumbing specialist without picking up a few of the basics.
    You asked Can I solve bathroom gurgling before it happens, yes you can or you can ignore the advice you are given and live with the gurgle !

  • Thanks anotherbaldrick, I'm going to put in a crossover tee instead, and get about 2ft height from the upright joint and put an air admittance valve on top of it. I can hide this ok.

    Antivac trap on the bath and an inline Gurgle Master (yes there really is such a beastie) in the shower waste pipe.
