DITRA Installation

Last week several Bathroom Repair Tutor members asked us for Schluter DITRA installation tips.

Why are so many people using DITRA? What the heck is it??

Don’t worry, you’re not alone. Lots of people have these questions.

Let’s get to the bottom of this.

What is Schluter DITRA?

DITRA is an isolation membrane. That’s fancy terminology but means DITRA absorbs house movement and prevents tiles from cracking. DITRA is installed over wood or concrete subfloors. Then tile is set over it.

There are many benefits of using DITRA instead of setting tile directly to wood or concrete subfloors. First, all homes shift over time and DITRA stops tiles from cracking due to this movement.

Second, DITRA can be waterproofed – which is great in bathrooms. Little kids (and husbands) tend to be sloppy bathers. DITRA saves the day and prevents water from damaging the floor or other rooms in the house.

Finally, DITRA is very light and thin. Anyone can install it. Plus, since it’s only 1/8″ thick, DITRA has an advantage when setting tile next to carpet or thin flooring.

Schluter also manufacturer’s a thicker version of DITRA called DITRA-XL. This comes in handy if the floor needs to be raised, e.g. to meet up with thick hard woods.

    Great info! Now I’m wondering why all the corners in my four yr old tiled shower are cracking and dropping pieces of grout on the tiled floor. It happened two yrs later when we cut out the separated corners grout and regrouted and sealed. What’s causing this and how can it be permanently repaired?

    Great vid o thanks. Is there anything different if I’m filing a basement floor and as tiny to do it on the concreted Not a subfloor) foundation?

    1. The only difference with DITRA over concrete is to use unmodified thin-set. Or use Schluter’s ALL-SET to bond DITRA to the subfloor. Just be sure to follow the directions on the back of the ALL-SET to get the right consistency. That’s very important.

    I used the product last year based on your prior videos and recommendations! So glad I did as I know that room is absolutely waterproof! Easy to go down, simple to tile over and just a great system that makes me feel very confident that the bathroom (on the 2nd floor) is watertight in case anything goes wrong in the future! Thanks guys!

    1. Thanks David, awesome to hear you liked it. DITRA is solid. Makes me feel more comfortable about setting tile in an old home. Plus the fact that it makes the floor waterproof is reassuring.

    Thanks for your question Kaye. Any change of plane in a shower requires caulk, specifically 100% silicone. Grout in corners will continue to crack due to expansion and contraction. Hope that helps
