I'm only a DIYer myself... so will bow to the greater knowledge of a professional.... I enjoyed the video as I'm researching how to do my own shower tray... however my takeaways are that I'll not be doing what you've done!!! ;-) 1) I'll be using a bed of sand / cement, 2) I'll be siliconing between the tray and the walls, 3) I'll not be using plasterboard for the walls... Tray / tiles, better than average shower etc.... the extra spent on proper waterproofing will add longevity... My home was new 20 years ago and in all 3 showers, tiles popped off the walls due to water getting to the plasterboard, being soaked up and destroying the wall... first there was the mould smell... then the tiles started falling off. I'm going to spend the extra on the tile backer board so that I don't have to spend money redoing it later.
Nice one AJ. I can really appreciate the work that's gone into setting up each shot and lighting etc. I bet it took you three times as long as it would have done without filming.
Thanks for the comment, that's not my experience with this method. I would estimate I have done 20+ like this. I have also fixed large 2.5m x 1.2m plasterboards to walls with the fixing foam, no sagging or movement was evident. I will be doing a review video of this showing how little flex is apparent if any. AJ
There is one specific problem with this method when using longer and low profile trays. There is some flex in these kind of trays, so by placing the blocks in the corners, the foam can't expand uniformly and is forced to expand where the tray is weakest - in the centre. Whilst the 4 corners may sit level, over the course of the 24 hours, the foam keeps expanding and the centre of the tray can flex upwards under that pressure. This creates a high spot in the centre that can actually be enough to level out the manufactured slope. I know this to be true because it happened to me and I've seen it in 3 other jobs since. In all cases, the trays were holding small puddles of water and had to be ripped out and redone with cement/tile adhesive.
Excellent bit of advice, I guess if there is enough space for the foam to expand that wouldn't happen. It's not something that has happened to me as I tend to put the foam down in lines and not fully cover the floor, I also find some but not a large amount does escape from the front and also down the hole in the boards around the waste. Thanks for the info AJ
I must say I was troubled with this approach although I enjoyed the video. Perhaps the foam might work, but I daresay a sand/cement mix is a more proved way for longevity unless you use a non-resin tray. 😎
It would surprise you to know that in fact it's equal if not better, I have several of them fitted for over a decade and never had a call back. Some sand and cement ones on wood I have had issues with. But it takes a leap of faith to try it for the first time 👍👍👍
@@ajinfrance Indeed, it is very interesting, and I have been considering options as I am right in the middle of my Bathroom renewal. I would prefer not to use sand/cement, so I might research a bit more in the meantime. Many thanks, bnkinireland.
I always use cement board for the walls instead of plasterboards. you'll regret it in the future when the water seeps through and the plasterboards wet's out.
Normally yes, but I used the Webber rubberised waterproofing as shown in my other video. Plus my tiling grouting and sealing is up to scratch. But I agree cement board is good 👍
Thks Man , u really solve a problem to myself, while wondering with shower tray placement on my garage's wooden floor. Thks thks. May I send a private text in case of any extra little doubts? 💪💪💪💪
Thanks for watching. I have been fitting trays like this for a good few years. It is as level as it can be, if you don't put the blocks around the top then it will probably not be level after it expands. I used to use sand and cement but this is much easier and quicker.
Where is the waterproofing?!! This is insane I keep seeing this videos where the seams of the shower tray are unsealed between the wall and edges. In 5-10 years time that silicone seal will never hold up and you’ll have mould and rot.
I think this is the 30th tray I have done this way. I was sceptical at first also but I wouldn't go back to bedding in on sand and cement. Try it on your next one you will be surprised.
Always have used expanding foam. Never had one move let alone crack Always use a decent low profile stone resin tray Also atleast 1 tube of decent silicone along any surface the tray meets push the tray into the silicone so it oozes out for a seal that will never leak

Yes you can do it that way. I started fitting the trays in the 90s using the same method so it does work it's just not as good. Good luck 🙂🙂👍👍
Great to see what you're doing. I've done the expanding foam idea and watched a 1.8m shower tray lift off the floor. Not sure if would do that again.
Wow, that's interesting. I always leave the gaps to collect the foam. If I did a full bed of it I guess it may affect things
I'm going to try it this way the next time I fit a tray. It looks easiest and less messy. Cheers
Great let me know how you get on. AJ
Nice one AJ. I can really appreciate the work that's gone into setting up each shot and lighting etc. I bet it took you three times as long as it would have done without filming.
Thanks Colin, Yes as you know it takes way longer with the camera rolling, and thats if you get it right first time.
Expanding foam will crush under weight unlike sand and cement and possibly will allow the tray to flex.

🤣🤣🤣🤣🤣 did you really just expanding foam the tray down…. 🤣🤣 lash up…

cement board is better than plasterboard !!!!!!!!@@ajinfrance

no manufacturer would ever agree to this method so wrong!
Thanks for your comment 👍
What sort of foam the sticky foam or just a normal foam ?
I used expanding foam in this one but you can use the non expanding version. Just leave gaps for the expansion type.
Expanding foam. That is a new one. Seems alot easier the sand cement. How's the shower tray working out? Any problems with leveling
Thanks for watching. I have been fitting trays like this for a good few years. It is as level as it can be, if you don't put the blocks around the top then it will probably not be level after it expands. I used to use sand and cement but this is much easier and quicker.
How NOT to install a shower tray - I hope no-one follows this or you will see leaks and potentially a cracked tray
Thanks for your opinion 👍
Hi what is the name of the foam ? Thank you
Good question - I use the Sika branded stuff usually and that works well
@@ajinfrance thank you
Where is the waterproofing?!! This is insane I keep seeing this videos where the seams of the shower tray are unsealed between the wall and edges. In 5-10 years time that silicone seal will never hold up and you’ll have mould and rot.
Ahhh yes then look at my other video called waterproofing the shower area. I used the Webber system which is popular in France. Thanks for watching 👍
That shower tray is gonna end up leaking 100%
I'm afraid not. If you do it properly will last as long as the bathroom. Have done so many dating back 6-7 years and no issues yet.
Show some respect to a tradesperson
Expanding foam lol ,,get ready to buy a new tray when it starts to crack.
I think this is the 30th tray I have done this way. I was sceptical at first also but I wouldn't go back to bedding in on sand and cement. Try it on your next one you will be surprised.
Always have used expanding foam. Never had one move let alone crack
Always use a decent low profile stone resin tray
Also atleast 1 tube of decent silicone along any surface the tray meets push the tray into the silicone so it oozes out for a seal that will never leak
