Any sifu here can teach. I want to DIY, piping from my bathroom through wall to the balcony outside which have no water tap. But I cannot find any accessories to lock the pipe to the wall.

What do you mean by "locking" the pipe to the wall? Are you looking for something to hold the pipe on the wall or what?

Thanks, that can also do... but I'm looking for something like this
But that is for copper pipe, what about PVC pipe.

My understanding is that I will core through the wall for the usual 1/2' pipe but I am not sure how do I secure them.

Holding the conduit run https://shopee.com.my/1-inch-25mm-or-3-4-20...2704.2402555214

Covering the hole in the wall https://shopee.com.my/Wall-Hole-Wall-Hole-D...7322.3534975184

Can use something like this as the end fitment (https://shopee.com.my/BIGSALES-PVC-P-T-Socket-Tee-Elbow-PVC-Pipe-Fitting-With-Brass-Thread-i.97231545.7946864725) for the end (tap) / the cover plate will grip the screw thread of the tap

You will need a 14mm or better, 16mm drill bit to core 1/2 in pipe. However it is more common to use 20mm PVC pipe. Do take note on the pipe colour and fittings. Grey piping, all must be grey all the way. Cannot mix colour with white or blue or black, won't fit

Like this also can. Hardware shop mostly have it.

Thank you for your detail explanation . It is very informative. My original plan is hoping to directly come out of the wall and secure it like the video or https://shopee.com.my/1914-SIZE-1-2-Decorat...7163.6038776188 But that is decorative and cannot flow water.

Because currently both end is not fix to the wall and in order to secure then, I will need to use elbow joint to bend it 90 degree parallel to wall, then only secure it.

Thank you, but this mean I have to use elbow joint to bend the pipe 90 degree to secure it to wall and then bend back 90 degree to attach the tap. A bit less elegant but I think currently that is the only solution.

Are you going to drill the wall at the same height you want the tap is it? When I do that I just drill the hole size that will fit the pipe. So it will be secure in the wall. Then apply some filler at the opening. Or you can use something like this.

If you have a grinder and/or rotary hammer AND the wall has no existing piping/wiring in it AND NOT structural wall you can have the pipe concealed and also the mountings concealed inside (patch back with concrete mix later) so you can come out from the wall neatly.

Since you are taking from the bathroom - which has existing water piping presumably in the ceiling you can make a T joint and start the pipe run from there? If making new joints I prefer to use the screw fittings, yes they cost few bucks more but troubleshooting/removal is painless as compared to having everything hardcoded (chloroformed ones)

Thanks for your suggestion, but bathroom already have tile, so I want the minimum hacking. The best way to do is carefully bore through the tile then the concrete to outside wall. If unlucky some tiles may break, but as it is under the wash basin, it should be OK as it is hidden inside.

There is no pipe from the ceiling as this toilet have concrete slab on top, it is connected in the wall that run to other part of the house, then only to the ceiling. So, making a T-joint from there is a lot of piping.

Yup, it is same height.
I see, these thing is call flanges. Thank you for this info.

I hope the pipe can go through it.
