Shower tray sealing tapes

[jrtrrror]

Hi. I have have purchased 3 Mermaid wall panels to replace the tiles in our shower. These panels are 3mm in thickness. After removing the existing wall tiles, I have discovered that there is a gap around the entire shower tray, in some places the gap is greater than 3mm, the thickness of the wall panels. The instructions for the panels say that a bead of adhesive 6mm thick is to be used to affix the panels to the wall, but obviously this will squash up to almost nothing as the panels are pushed against the wall. This would effectively mean that front edge of each panel would only just be sitting on the shower tray. And in some cases, may even sit behind the tray, this is obviously a big no no. I was considering replacing our shower tray with a Mira Flight tray with the integrated upstands. However, after discovering that the upstands are 6mm thick, I don't think this is going to work very well. The panels would effectively have to slightly bend towards the bottom to sit over the 6mm thick upstand.
So, as an alternative to having to re-plaster the shower area to close the gap between wall and tray, which would be time consuming and would mean I can't move forward until the plaster has dried, I thought about using the Mira upstand strip. Mira Tile Upstand Strip 3.6m White - https://www.NoLinkingToThis/p/mira-tile-upstand-strip-3-6m-white/5361X?tc=MB7&ds_kid=92700046986170840&ds_rl=1241687&ds_rl=1245250&ds_rl=1245725&ds_rl=1245250&gclid=CjwKCAjwhNWZBhB_EiwAPzlhNrEj2LfoHWSgoQiIHG0RqUlrh2VLVzNSDr1pnFLJoSeX2dnRq5Y0ohoCsK8QAvD_BwE&gclsrc=aw.ds
But do you guys have other recommendations for shower tray tapes that are superior?
Am I worrying to much???. I also intend on tanking the area with Mapai Shower proofing kit, and this has a tape that, according to the instructions should be adhered to the tray. Would this do the job anyway? Especially and most importantly, when I install the new tray I will be ensuring that there is copious amounts of sealant between the wall and the outer edge of the tray.
Sorry, lots to read there. I just want a solution that doesn't involve replastering and I definitely can't replace the wall panels with thicker panels.
Many thanks

Other than measure twice cut once

Well, I was going to use the cardboard that the wet wall sheets arrived in to make a template of each wall. Once happy with its fit, I would transfer my template to the panel and cut it to shape.

Looks simple but believe me it awkward as hell 😜 I use a good quality clear silicone to stick panels then brace them , get yourself some masking tape to draw your cut lines onto far easier to see . Kop

What a transformation KOP. Are the panels tongue and groove? Looks great.

Or 3mm ply and hot glue I use for fun shapes

KOP. I'm not entirely sure if there is a Direct Message option on this forum, you may feel happier answering the following via a direct message, rather than posting in public...
That bathroom that you've just sent pictures of looks fairly similar to ours that I'm working on. It's taking me ages to do, because I'm doing it at weekends and occasionally in the week, if I'm struggling to get on with my job because of the weather. Additionally, Im not a bathroom installer/plumber, so when I come across issues, (of which there have been many), I have to investigate options or products that will resolve the issue. I really care about doing a good a job within my knowledge. May I ask how long the bathroom you did in the pictures took you and how much it would cost the customer? I completely understand if you'd rather not. I only as cause the Mrs complained the other day, saying it would have been cheaper to get someone in. 🤣🤣

Well if that's the case Ben -gee then I'll move to another product there's more than one mate I've used shower wall which is MDF but didn't rate it , I'm using the frost white this week must be older stock as it's ply backed ? Kop

Yes I told my supplier that I’m not happy to use mdf ( even if they call it exterior) so I’ll be switching to Mermaid Trade panel , he told me they were likely to go mdf too but not yet.
It looks like the “nuance type” minced up plastic panels may have to rear their ugly heads sgain!

Just a word of caution the cheap 250mm wide panel is really not good it punctures super easily and is second rate stuff. Looks nice new. I have used classi seals a lot and I have taken baths and showers out with them on and it's pretty resilient stuff. Tiler can still tile over it as it only sticks up 50mm or so

Yes I get the panels hydrolocked when ordering it takes two people to do the job and it can easily take a 5 days to just do the paneling in a whole bathroom , and you really need the proper equipment stands to support the panels and a rail saw is a must and gives a nice machined edge, hand saws, jigsaws won't cut it and will chip and damage the laminate a whole bathroom can take 3 weeks+ and costs vary on complexity, your shower I'd say around £1000 to prep and fit out , a whole bathroom can be £6000 - £10,000. Depends on the finish and chosen fixtures and fittings flooring , ventilation and electrical work . Kop

Have to disagree there's never over kill where showers and trays are involved the prep is the most important part of the job, I do at least 10 - 20 a year and from reading the ops description of what's he has I'd seriously consider it ?
I wouldn't personally use a 3 mm board for showers , I'd use the thicker 9 mm cellular shower boards for a more affordable job , l'm starting one on Monday with Multi panel my favoured product. Kop

Hi KOP. May I ask, why would you not use the 3mm boards. Can you elaborate please?

If there is going to problems during installation, I would prefer to know before hand, especially if you have advice on how to work around any potential problems.

Your advice would be much appreciated.
Thanks

They are to thin for my liking ok for splash backs but not robust enough for me, but manufacturers instructions say they can be used so your choice really . Kop

Ooo you’ve second-handed that bath somewhat!
Nice little job those, please report on how your multipanel turns up mdf/ply.

It ply mate I checked but your right they are going over to MDF big mistake it's been tried before and failed , looks like it's Dura panel from now on not so many pattern choices but they won't be changing to MDF

Got the panels and shower fitted up graded the extract fan replaced flexs and grilles , plumbing alterations to do today customer is now away for a few days so a bit easier
Shower tray to fit , then shower doors going in .
Can't carry on with the rest till the new year as committed elsewhere, this week was the only spare time I had between now and January busy busy. Kop

 

[Ben-gee]

Interesting that you fit the boards before the tray? Makes that a lot easier!
But doesn’t it result in a large silicone seal at the bottom to get over the tray radius?

 

[jrtrrror]

Hi again Any recommendations on a lightweight, reasonably priced tile backer board? Preferably at least 800mm wide.

Hi kop, on the picture where the shower trap is sunk into the concrete have you used a glued 1-1/2 connector instead of the usual compression fittings they supply or did the trap come with a glued connection?
