You need piping of the same size, probably 8mm or 15mm. And some joints, the exact ones will depend on your existing pipework. You'd probably be best adding in a couple of shut off valves in case of any problems, you'll be able to still use your bath.





Cut your existing pipework, add in the t-connections (at a guess) so that you can continue the pipes to your bath taps and then you have a new connector to add the pipes up to the shower. Add a shut off valve to bot hot and cold on the upward pipe so that your bath can be used if you shut off the shower valves.What materials do i need to install a shower over a bath taking from the cold water supply only?
If I were you I'd call a plumber!





If your still hell bent on doing it yourself.. buy a new set of taps with a shower connection on the top of it. It'll be the easiest option and will probably save a downed ceiling or two.





If your unsure, I really would get someone who knows what they're doing, water can cause massive damage to your home, and your missus will kill you !!
either way you are going to have to tap into your hot water supply on less you would settle for cold showers only, whereever you tap into your cold and hot lines you should have a shut of valve on the both of them and then from there you will tie them back in with a T Pipe, Run the pipe to your shower get a 90 degree pipe there you go, measure correctly, don't forget to get some plumbers tape, and some sauder, ourelseyou well have troubles


with leaks.
You will need a pipe, for sure.
If you have a single handle type shower (which most are these days), take off the knob that controls the water flow and the metal plate behind it. In the hole in the wall, you should see a brass fixture (valve) with two slotted screws, one on each side. Turn the left screw all the way in (clockwise) and this will shut off the hot water side to the fixture. Replace plate and knob. You don't need any materials.
You can do this with 15mm pipe and compression fittings. Be careful not to untighten something when tightening them. Put some PTFE tape around the olive to stop leaking. Also fit an inline isolator which will have a compression fitting at each end. Buy some saddles to fix the pipe to the wall and probably a right angle compression fitting to enter the shower.
