How many times have you sued professional services out of interest?

Well I cleared the tools out...

"I just need to use the head!"

This comes up a lot. Have a good read here:

Dymo labeller at Aldi: https://www.aldi.co.uk/dymo-labelmaker/p/803497428917600? Ideal for making grid switches look dog rough! ?

Illbruck is a name to conjure with. Really good stuff. They do airtight expanding foam and tape too similar to Compriband. <£10 a tin to go in a foam gun. A couple of quid cheaper you have Everbuild acoustic/airtight foam. We have a "window" man on here, can't recall his name, Craig?

I nearly bought my lad a laser engraving add on head for his 3D printer at Christmas. I couldn't for the life of me think what to use it for at the time! I was thinking wood/leather. Saying that I'm not too sure how plastic will fare with the laser...

A bit late now but... ...you can always mount the grid horizontal and have the writing in line with the switch action. Saves you getting a stiff neck! ?

& another place: https://www.laser-techniques.com/switch-plates-electrical-accessories I think that Schneider themselves offer the service. Certainly do for the control gear legends I buy. I will ask my man!

Change the grid plate to a metal one and get it custom engraved & colour filled? Tbh I think they engrave / fill plastic too: http://able-engraving.co.uk/engraved-products/grid-and-switch-plates/

I see I used Sikaflex on the sink waste. Tbh think I did on the bath too:

Exactly where is it leaking? Around the black nut or where the white waste screws on?

I'd do away with the washer on top, they tend to be a bit generic, one size squashes to fit "all". I'd put a big slug of BT1 etc around the waste. Similar principle to how I did my bath waste. Ditched the top washer, kept the one underneath. The top, baby wiped to finish: Same on the washer underneath: Tighten but do not let the top turn even if it means SWMBO standing above. You want to compress rather than "smear" which will kick it all out of the joint (so @Nickfromwales said).

Decent foam, done right? is alright. Compriband BEFORE the windows/doors go in is better. Is it all going to be airtight taped?

Why can't you spin the U bend round so it faces the waste pipe then reduce there? Is it all solvent weld at the back?

You do like to make things hard for yourself.

The boxing in up by the ceiling, is there a pipe/drain behind that?

The 4th picture of the opening post appears to indicate something boxed in. Could that be "pipes" where a joint has failed?

They're wrong but you're still a lunatic! ?

Though I cast my shower corner floor to falls for a wet room corner, I did the main slab, with mesh in first. I just shuttered off the for the shower corner (and part sunken bath): I did though remove the red Polypipe panel in this area to get a consistently thicker, stronger slab. What a mission that was cutting it up in bits. Similar fun was had then fitting a bit of DPM with the mesh in situ! My SBR heavy, 10mm pea shingle, concrete mix: A few on here have just left in a bit of EPS level with the FFL that you dig out later. You can decide on your trap position later.

The instructions say to mount at eye level and in a 35mm back box.

Same old same old. Improve your property, increase the value and cop even more tax.

Have a look at the some of the images here.
