Étape 1 -

To fit inside the existing frame I had to bevel my 20mm plywood to half way. By clamping a straight piece of material onto the edge I could simply push against it with the router while moving laterally to get a clean and straight cut.

Étape 2 -

Lay out the cut lines on top of the plywood (and clamp/tap it down).

Étape 3 -

Use a circle saw to cut the holes for the hot/cold water mixer.

Étape 4 -

Missing from the step is how the water proof membrane was attached to the 'wet' wall. Ideally some kind of glue would make the most sense.

Insert the mount plates through the wall and using bolts or cut threaded rod, washers and nuts fasten the mount plate/filter or regulator to the wall. The holes where a bit too far out for the mount plates so there was too big of a gap to just use nuts to hold everything tightly together, so some 20mm plywood was cut and holes attached (in the same positions as the mount plates) to get a tight fit between the mount plate, plywood and wall.

Étape 5 -

Here's a picture of Timm and the back wall in it's entirety. The black semi-circles are something that came with the UV-lamp which let's us mount it easily. Normally this would be on the inside of the shower but this version was so big it couldn't fit inside the shower horizontally. While smaller UV lamps of 20W should be sufficient for 10l/min the numbers seem to vary from supplier to supplier and I would lean on the side of caution. A cool set up could be to have a small UV pre filter and after the filter whereby the pre filter UV may be good enough to reduce or stop bacterial growth inside the filter all together which does occur even in drinking water filters, but the type of bacteria isn't harmful. In either case this is what the post-filter UV is for, to make sure that there are no negative effects.
