What is the best way to fix a bath spout to what will be a tiled bathroom wall?
The bath spout comes in two bits: the spout with a 1/2" thread connection (but a flat machined on to the thread - makes sealing tricky!); and a plain chrome plate with hole that fits over the bath spout thread.
So plate must go over thread, then assembly is fixed to the connection and fixed to the wall. But how do I make it strong enough?
I haven't made up any pipework yet. Pipes will be behind cement board that are then tiled. I will cut a hole in the tile for fitting the spout.
Endplate elbow has been suggested, but the flat on the spout thread looks like an obvious leak path. Just add plenty sealant? A flexible tab connector seals nicely with its rubber seal, but leaves me with a fixing issue. Will the spout be suitably supported?
If the elbow is firmly fixed you won't need any other support to "make it strong enough". The tricky bit is getting the elbow in the correct location so that when its all tiled the spout is also in the right place. I can assure you that comes with practice.
Tile around the female - don't worry about sealing it in.
Use ptfe tape or jointing paste on the threads only of the ½" male on your spout. Don't worry about the "plate" its irrelevant to getting a seal and dertainly do not throw silicone around it - you'll just end up with a horrid mess. You may have to adjust the amount of tape / paste to ensure that the joint is watertight but also that the spout is nice and level (ie not pointing round at an angle!).
When you fix the spout you will find that the chrome plate covers up the whole in the tiles. A little - yes just a little clear silicone sealant bead on the back of the chrome plate as you tighten it all up is sufficient.
