Plumbing day 2

 This is the control box for the digitally controlled shower mixer.

 It was fairly simple to plumb it in. I used an isolator terminal to take the power from, but this still needs a power feed connection

 

I completed the plumbing under the floor, using solvent weld for the drain connections and using isolator valves ready to pick up the bidet when I can re-connect it.

The wet room base was then screwed to the floor underneath. I then started the tanking. The kit comes with a system from Weber, sealer, rubber tape and then the blue waterproof tanking gunk.

This is the Weber system contents

 This it the nook, I thought that needed protection.

Otherwise I just followed the instructions concerning where to put it. I am only tanking the sections that I am ready to tile, so that I do not need to walk on it afterwards.

This is a good time to show how the floor is engineered to run water away to the drain. The floor underneath was level, but the spirit level shows the contours of the wet room floor.

Just a slight slope at the edge of the drain

The drain is perfectly level

Dismantling the shower, and starting the plumbing.

The en-suite to our bedroom has been the same since it was installed 17 years ago. Time for a change!

My daughter installed 2 new bathrooms a few months ago. This gave me inspiration to try the new things now available. let's see how it goes.

The shower tray was pre-cast concrete, 1200x700mm, with a pivot glass door, and a Shires mixer shower valve. 
















 Dismantling it was not too much trouble, however it was grubby under the frame, and there was some water damage behind some of the tiles.

 The tiles came off easily. They were loose in places resulting from the shaking that the house got from the Buncefield explosion. You can see the water damage where it had seeped through the grout.

 Once the shower tray was removed, I took up the floorboards. I needed to cut the boards so that they sit flush with the top of the joists. The new wetroom shower base then sits on this so that it is flush with the floor.

 I had to remove the bidet as the new shower will be 1400x800mm. The waste from the shower picks up with the waste from the bidet, and I have moved the water supply for the bidet closer to the toilet.

 I removed the plywood from the wall to run the pipework for the new shower. It is a Mira digital shower. The mixer will be near to the hot water tank in the airing cupboard. I have to run separate pipework for the rain-water shower head and the traditional shower head.

 The pipes end pointing out from the wall. I will need to cut holes in the tiles to fit over the pipes.

 Here the pipes run out through the wall to the airing cupboard

 I am considering making a nook in the space where the spanner is, to be a shelf for shower gel etc.

This is the pipework emerging into the airing cupboard, ready for the connection to the mixer unit. The capped pipe that you can see is the feed to the shower before I disconnected it all.
