Onoff

Quality with quantity that...except for the tiling...

Amazing, my nephew sent me that exact photo on WhatsApp the other week as an example of good plumbing. He has a sore bum too apparently. Didn't know he'd been to Bristol recently.

The basin size is usually 1 1/4", bath is "1 1/2".

Yeah, I know! (Note the position of the comma btw, that's me being pedantic). 😂

The 1 1/2" usually relates to the inside diameter of the pipe. Can't you bathe in the stream? 😂

Have a look at @Nickfromwales detailed comment here on p13 of my mega thread:

In your house maybe! I'm staying in the lounge where it's 11.6degC any warmer and I might have take the blanket and wooly hat off! SWMBO currently outside trying to thaw the kitchen waste pipes that run around the house perimeter above ground. Frozen solid meaning the washing machine, dishwasher and kitchen sink can't be used. Boiling copious kettles etc. When I said about sorting proper drains...you'll take too long, the mess etc. Usual insanity.

A brilliant concept but what will ensure the mass homebuilders do them properly with the attention to detail that's needed? Going to need to be a sea change too in the attitudes of many trades.

It's corduroy too, very 70s! Someone was chucking it out. Still, it keeps our feet off the lounge floor, currently the thermometer there is showing a balmy 10.9degC...the one mid air in the centre of the room is 17.6degC. Heating has been on since 9am with room stat set at 30degC. 4degC in the bathroom though it did get up to 5...

Here you go @zoothorn, my lounge. Suspended timber floor, clay air bricks open to the elements. I've hung a thermometer from the light fitting with the probe midway between floor and ceiling. Just in front of the second "P" in HAPPY. Temperature is reading 20.5degC. Then there's another on the pouffe with the probe on the floor. That is reading 13.4degC. So one probe directly below the other. No wonder our feet are freezing!

Sarah Millican's boyfriend would love your shed!

I suggested this. Even that my jobless 23 year old could do the digging etc whilst I'm at work. SWMBO thinks we should wait until Spring. ???

Tbh the bathroom did feel nice and warm, even without heating until I punched multiple holes in the ceiling for the body dryer, speakers and down lights. Might be my Christmas mission to make good those areas.

It was alright until the tiling! Tbh, now I've done the one room I'm completely confident to do the rest of the house. Just wish SWMBO would get onboard.

As others have said, multiple times it'd be an idea to do a test dig. Yes btw I've done similar in a single room. First clear the room! -Kango the floor: -Remove the floor to separate pile outside. Think I shifted about 70 or 80 rubble bags then the soil on top: -Dig down. The depth will vary according to your floor build up/design: -Distribute the soil where you can outside. It grows btw. -Grade the removed floor / break up to reuse as a sub base. I used max 40mm. -Level this off. The paint splodges are where I had stakes banged into the dirt to ensure a constant hardcore thickness: -Compact: -Blind with sharp sand: -Lay a layer of 25mm EPS: -Lay a DPM. Note there's a 2" thick upstand of EPS around the perimeter. This is to help take up the expansion of the slab when it heats up. (I did too add extra expansion strip). -Lay PIR min 150mm. Did mine in 2 layers, 50+100, staggered the joints and foil taped: -Lay UFH pipes, cheap even if you don't use them. I used Polypipe panels but you can staple to the PIR if you put another plastic membrane over the foil face: -Lay A142 mesh: -Lay concrete 100mm deep. I had various areas shuttered off for the part sunken bath and wet room corner. I used "wet" mixed concrete. I forgot to add strengthening fibres to the mix for this! The mesh should negate the need.....I hope. The concrete comes to the height of the expansion/perimeter strip. -Tile: Ask multiple stupid questions along the way and take years off forum member's lives in the process! 😂

Have a line of bricks level with the top of the lintel and a uPVC packer underneath?

Have you got a wall plate to go atop the blocks? Add a 55mm bit of timber or 50mm uPVC extension piece?

8 in the bathroom, 19 in the stairs room, 24 in the study, 19 in the lounge.

@zoothorn it looks great. Very easy to doze off in there I bet! Tell me you fitted smoke & CO alarms in there? Kidde do combination ones.

I think it's Finland where the chimney takes a convoluted route to better heat up the mass of the chimney stack.

Just wait until he turns up on one of your actual sites!

If you've been a good boy somebody might need those chimneys soon!

It's very easy to install Celotex wrong. How you cut, i.e how square can have a major impact in how tight it fits against the joist. One way of near guaranteeing at least one side is tight to the joist is to cut 5mm under width. Hold in place with some nails then gun foam the hell out of the gap.

So.....in the sketch below, if the black is the aluminium spreader, that has to be butt tight against the underside of the routed chipboard (where the arrow is)?

11.6 degC in the lounge here when I got up. Sat with a fleece jacket and bobble hat on. When this black coffee I currently have my hands around has done it's thing, I'll need to brave the bathroom 😉
