Wetroom Former Size brand and type - Tile Advice

YT233 · Feb 15, 2018

Hi All,

Please can you advise what former I require for a wetroom area of 1450 x 1100?

Looking through this forum, I know the impey former is not highly regarded. However, Wedi seems to be. Is it possible to cut the Wedi primo 1500x1500 tray down to my size?

The former will be fitted on to wooden joist, so that it’s flush with the rest of the floor.

Kind Regards

Hi
yes it can be cut. Even amounts off each side.

Thank you for your reply, what is the best method to underboard, I take it the Kerdi tray are not suitable due to size?

Nothing wrong with impey I'm involved with several of these every year

Agreed. What gave you the idea that Impey are not highly regarded?

Impey one of the better ones.

Hey to be fair I've installed 2 this year already.
But I used Mapeguard and Kerdi, fixed with Kerdi-coll on mine.
(The drains are still rubbish though - and naff grates)

May I ask what you mean by the drain being rubbish?

Can a Kerdi that size be used for my sort of install?

I've always moaned about them not being integral to the tray and the lack of weep holes to allow sub surface drainage. But if the drain is properly installed with membrane properly fastened in, and epoxy grout is used, I'm happy enough with them. The main attraction is that they sit straight on the joists.
As for kerdi, yes you could but not easily. The edge height would be approx 45mm from memory so your into shaving joists which is not always possible. Plus increased time installing.
The plus side, they look great and integrate to the walls brilliantly.

This was 1700x1200. As you can see, the tray wasn't exactly of the shelf and due to 3" joists in a very old barn, had to be built up.

What if you ply upto joist level in the full room. Install a Tray such as the Wedi using thin set then get the rest of the floor up using Wedi or Kerdi 20/40mm construction boards?

Certainly a good option if you can stand the increased height at the doorway.
Wedi fundo ligno is your best bet. Only 20mm at the edge.

Try a Jackoboard (jackon) shower tray tons of sizes and designs including cement boards..your local CTD will have these to show you have show you available ranges..

With the Wedi shower trays in particular the Fundo ligno, they recommend setting the waste in mortar by making a box between the joist, placing the waste in and filling with mortar.

Is this an essential part of the install?
