Working Shower can be operated with a stone button. Press the button to on or off the shower.
Go through the guide and follow step-by-step instructions to make one.
In order to make a working shower in the Minecraft game, first you have to make some space for it by placing smooth quartz blocks on the ground. Make a base and then a complete wall on two sides as shown in the following image.
Add white stained glass pane in the middle for shower and use smooth quartz blocks for the roof.
Add a dispenser by breaking the block from the top corner. And then use a bucket of water in the dispenser.
Add a stone button on the left just next to the glass pane and a torch at the back side of this button. Place quartz slabs on the wall and use redstone dust on them as shown in the image below.
You have successfully made a working shower. Press the button to turn it on and then press again to turn off.
