Current good practice requires that a tile backer board is used under all tiling and/or a waterproof membrane like Schluter Kerdi with debonding membrane on the floor. The reason for this is that plasterboard and stud partitions and tiling move around and cause minute cracking of the tiling grout (even if it supposed to be 'flexible') allowing moisture to get behind the tiles and plasterboard and affect the timberwork, usually in the floor where it can't dry out. Water resistant plasterboard is not the answer as many examples show. With this construction all you can hope is that it will not be a noticeable issue for a few years and after that a major refurbishment is necessary - this is borne out by many instances I have personally been involved with. Also, the niches need a slope to the cill section so as to shed water otherwise the grout becomes black with mould quickly, I hope the tiler knows this. If the floor is to be tiled then the tiles need to extend over the full area and under the shower tray otherwise when the tray jointing breaks down, as it must, water accumulates under the shower tray rotting the floor from the shallow contained area.
Is this the first sighting of the underneath of the loft stairs in their finished state? Lost touch with the progress on that...Had to freeze frame for a good look - it turned out great! Learning so much from your channel. Came here for Rich's roofing how-to content but have stayed for everything else. Thank you for all the trouble you go to.
Thanks for commenting Martin. There is a short of the finished article and I dare say if your watching all of our episodes now you’ll see it finished and painted quite a few times. Thanks for watching 👍🏻
@@Mr_A_Builders Not if, but when the damp gets behind and under, the substrate will become wet, tiles will loosen up and no amount of calk will fix it. Plenty on YT about this and why the new codes are being introduced.
Hi Paul and thanks for commenting on the channel. Having managed sites as well as being a tradesmen on them I always found that BS were open to interpretation which were pointed out to me many times during NHBC inspections I know for a fact that on new builds the requirement for wet areas such as showers is a green moisture resistant plasterboard. Dabbed or mechanically fixed. The waterproofing of the substrate refers to in most cases tiling of the area along with an approved adhesive and grout for that area. In my opinion if the plasterboard gets wet you’ve done your job wrong anyway either way whether it’s hardi backer board or a solid wall which has been skimmed the moisture behind it will still fetch the tiles off the wall either way. On our channel I can say honestly that we do everything, to the best of our knowledge, the correct way no matter the cost for the materials or the labour. Do you think that the obsession with the use of hardi backer and tanking has come from America? We both know that they use it because of their timber frame construction and the worry of rotting of the structure.
Hi Keef. Thanks for taking the time to comment. We have always used moisture resistant plasterboards in the shower area in addition to a good quality adhesive and grout designed for wet areas. We have worked in the same area for years and regularly see customers from jobs 5-10 years old and we have never had a problem. I can however see what your getting at and agree that the use of cement/backer boards is used as well for this purpose and would provide a good base for the tiles as does green plasterboard. Have a good evening 👍🏻
@@Mr_A_Builders In 2022 we tank, we don't use plasterboard and hope the grout will remain waterproof....as it never does. Each to their own, not sagging you guys, but if it was my house, you'd be tanking 😂

Looking great, downlights on the landing look smart. Bathroom - very nice finish lads, nice work 👍
Thank you. Appreciate you taking the time to comment
No tanking, mucho problems!! Need to tank that shower area boys!!!
Morning Jeff....this is a loooonnnngggg subject so I won't go into it too much and take up loads of our time but I will ask this one question...why?

BS 5385-1 requirements for wet areas are very clear. Substrates must be waterproofed with an appropriate material. Otherwise nice .

Looks great. Another good job from Matt 😂
Cheers Jase and yes didn’t Matt do well 😁👍🏻
@@Mr_A_Builders 😭😭😭👍👍
21:24 😂😂Hahah I didn't realise Mark was a short guy. Does he drive a red and yellow car too.
Haha! You should see him drift it round the corners!
@@Mr_A_Builders I hope he doesn't leave skidmarks. Double meaning intended. 😂 Great videos btw. Binge watching them as we speak.
Ah mate that's ace! Hope you enjoy them! Whether you do or don't please let us know either way! Cheers man.
Don’t those decking lights make one hell of a difference.
Cracking job👍
Thanks Billy

No tanking of the shower area? No cement boards? 🤔
