The piece for the back of the niche will be the largest 24 1 2 x 12.
Floor elf kerdi.
However i have discovered a way to create a niche very easily with much less work and time involved kerdi board.
I am building a 2 foot high niche by 1 foot wide.
6 apply a 10 inch wide strip of kerdi band along all floor to wall transitions using thinset mortar.
At a schluter workshop they said that after curing the kerdi onto the foam tray it has a strength of 500 sqin.
One person should lift the front edge of the tub while another slides a couple of 1 x 4 boards underneath to get it off the floor.
An acrylic shower pan is an easier installation than a tile pan.
Cut away any caulk between the tub and floor with a utility knife.
Kerdi fix is a urethane sealant made specifically for kerdi products and waterproofs seams.
5 remove the tub be safe and have a helper for these next few steps.
If you are familiar with waterproofing a shower floor with schluter kerdi or any other topical membrane including liquids you know that you need a topical drain.
Schluter kerdi wedi traditional etc.
Now if the resin dissolves in wet conditions and it covers a lot of the area of the back i d be worried.
Don t have any idea what that means.
The floorelf describes his process for installing a kerdi board niche in a shower wall.
Slide the tub out of the alcove using the 1 x 4 boards as skids.
You need as close to full coverage as you can get and the resin if it softens or comes off won t provide that.
It s all fun and games until you have no place to store your rubber duckies.
If you don t then you simply have a shallow swimming pool rather than a shower.
This hole must be the exact size and it must be in the correct spot.
Question about the fixtures.
For the purposes of this post you will need 1 2 kerdi board 3 5 4 square feet for a 2 x 1 niche and a tube of kerdi fix.
Do you buy these at a big box store your local plumbing supply store or do you have an online source.
I ll read some on the floor elf thanks for that tip.
These differ from a regular clamping drain because they do not have an integrated weep system.
Kerdi fix is a urethane sealant made specifically for kerdi products and waterproofs seams.
When using kerdi for your shower floor you need to make a hole in it for the drain.
Begin by cutting all the pieces to the appropriate size.
There are two ways to do this.
