I will not use vacuum. I will be using a very long tube to route the dust out.

Not sure where to post, forgive me if I have posted at wrong thread.

I am planning to install a top inlet shower set which means bottom of the shower rail will be fixed onto the wall. But the problem is there will be a pipe behind the wall, from the shower tap at the bottom towards the top inlet.

So is it safe for me to drill maybe 1 inch (or even shorter, will drill and check)? Can I use a shortened wall plug (trimmed manually)? Or is there other method better for this kind of situation like liquid nail (xbond)?

Do not drill within 2in clearance vertically of any outlet coz obviously pipe will be there.. u offset ur fittings accordingly lah. Else will be a mess (hack tiles) to fix leaking concealed pipe.
Stick two lengths of masking tape up from the outlet or tap so you will not miss the NO DRILL ZONE.

Yes but for that type of shower set fittings, it has to be mounted at that spot which is vertically above the tap. So I guess I have no choice but to use liquid nail? Is it ok to use liquid nail in shower area?

Got pic? Worst case, use sth like aluminum flat bar make adapter bar so that it can still be affixed to wall but not being drilled at critical zone. Liquid Nails will stick but if there is movement from day to day use it might drop off one day..

This is the best option to reduce risk to zero

Something like this. For the mixer tap, it's concealed type. I think maybe it will be detached but it won't drop off due to the top inlet connection.

The point you said need to fix to the wall looks like the valve point, right? Doesn't it need to be replaced by the fixture valve? Nothing to drill here. The point stated as Top Inlet is the point to drill and fix the holder for the rain shower. It is not the inlet, seems to me.

The piping is from the bottom up to the valve point only. So, at the Top Inlet point there is no piping, I strongly believe.

Your top inlet is your existing shower head connection and the piping stops there. You can drill above the existing shower head.

Nop, your statement is correct for bottom inlet (or normal type). For my case is top inlet, which means top is the inlet lol


Yes, existing head connection. But I don't need to drill above existing shower head, what I meant was I need to drill below the shower head and above the mixer tap where there'll be piping.

I guess it's too risky, so I'll see whether to use liquid nail or what Miss ceo suggested, connect using flat bar so that drill points can be away from the piping route.

Never seen one like that.

I thought the valve there water comes in and you can channel either to hand shower or rain shower at the top there

I don't have idea why need to drill at the inlet there

Yeah, it's not common haha. Maybe you can google on top inlet shower set or something similar.

Usually what ppl do is to connect a flexible hose from where the water comes from (at the top, on wall, 6-7ft high) and towards the shower inlet which is normally at the bottom of the shower rail which is mounted slightly offset from the middle. But I felt this is too messy, so am thinking of installing a top inlet shower set.

Again, im not drilling at the inlet. The inlet is at the top while the bottom (the valve there) is not the inlet yeah.

But nvm lah, thanks for trying to help anyways

Any tools that i can remove wall tile grouts without chipping the tiles?
I don't want multi-tools, i prefer manual tool.
Any recommendations?

Thanks. I used this tool before and it chipped my tiles. Too thick.
I need thinner blade.

Thin like this?

This blade will last shorter compared to the other one

Cant the 2 points connect to the existing inlet and tap with an adaptor ? Maybe you have to dismantle some parts to do the two connections and thereafter fix it back.

BTW anyone experienced with regrouting the shower room with waterproof grout?
Did it solve your moist issue with the wall next to the toilet?

I found this https://shopee.com.my/Cutting-Wood-Or-Hard-...7735.5432900216

Dunno can use on grout or not...hahah

This depend on disc. It will drag your hand in one direction like grinder and if not careful you end up cutting your shiny tile surface. If you opt for this, then better find cheap multi tool, easier to control.
