Tile to Concrete Threshold: Everything You Need to Know

Planning on renovating the home but have no idea on creating a doorsill? Well, we’re here to help. 

Since this is a common issue, here’s a guide on tile to concrete threshold. Here’s a small overview of the topic.

Thresholds are used to protect your home from pests, cold winds, or water during a storm. Thus, it’s been around for ages. There are many types of thresholds, made of either tiles, cement, or wood. When choosing a threshold for tile and concrete floors, best to go with tiles. Shape the tile and set them with mortar.

Sounds promising? Let’s take a look at the whole thing.

Why Use a Threshold?

Before we get into the types of thresholds, why need thresholds?

So here’s the thing. Thresholds or door sills have been around for a long time.

Although it’s a little unclear as to how this seeped into modern-day architecture, there are various folktales and superstitions tied around it. For instance, you may notice a new husband carrying his wife over the threshold of his home.

Let’s come to why it’s important from a logical perspective. A threshold near the entrance prevents water from seeping in when it rains heavily.  Even during the chilly winter months, it protects the home from cold winds.

Apart from the environmental factors, a door threshold minimizes the space between the door and the floor. Just like the gap between your tiles and wall is bad news, a gap underneath the door allows pests to come in. 

So all in all, it’s a pretty essential part of the door.

Choosing the Right Type of Threshold

So we’ve seen why thresholds are important. Now let’s come to the types of thresholds we see around us. 

You see, door sills can come in different materials. These vary depending on region to region. 

So let’s give a look at some of the most common ones. 

1. Tile Door Sill

This is the most common type of threshold, and for good reason too. That’s because they blend in perfectly with your home.

Thus, the doorsill doesn’t look odd or out of place. Moreover, they’re also durable and don’t chip easily.

2. Marble Door Sill

One of the recent trends floating around are marble door sills. First of all, a marble door threshold looks great. It adds a perfect touch of luxury to an otherwise normal home. Not only that, but the marble has a reputation for being hard and durable. So, you won’t have to replace it just because it’s chipped. 

Thus combining the two factors together, you can easily opt for marble. The only thing holding you back may be the extra price.

Although they tend to be a little more expensive, it’s definitely worth the splurge. 

3. Wooden Door Sill

Another popular material you may find in European or English homes is wooden sills. This is a more traditional material, that has been around for ages.

Not only are they a great match if you have wooden floors. But quality wood is also durable. The great thing about wood thresholds is that you can pick one according to your budget.

You may go for a regular wooden threshold. Or choose a fancy oak one. 

For most intent and purposes, a tiled threshold is usually what we’d suggest. They are the best choice for any home. Especially in terms of aesthetic and price.

Tile to Concrete Threshold

When building a threshold for the entrance of your home, the exterior may be made of concrete. In such a case, it might get confusing as to what material threshold you should choose. The same applies when you’re retiling a bathroom

But the solution to this is quite simple.

Whenever you have to choose a threshold between two different floor types, always pick any one material. So when selecting between tile and concrete, we suggest you go with a tiled threshold. 

All you have to do is shape the tile of your choice into a threshold. To see how it’s done, keep reading. Here’s a shortlist of things you need.

Things you need

  • Pry bar
  • Hacksaw
  • Tiles
  • Thin-set mortar

Step 1: Remove Old Threshold Or Smooth the Surface

First of all, remove any previous threshold that you may have installed. In case you’re doing a home renovation project, take off the old door sill with a pry bar.

If you’re making one from scratch, smoothen the surface of the subfloor. This will create a smooth base.

Step 2: Cut the Tile into Shape

After you’ve created a base, it’s time to shape your tiles. To do this, measure the dimensions of your door sill with a ruler. Once that’s done, cut your tiles with a hacksaw. 

Make sure you wear safety gear since you wouldn’t want to chop your fingers off.

Step 3: Set with Mortar

After the tiles are all shaped, time to take out your trowel. Dip it in some thin-set mortar and apply a smooth layer on the base. Next set the tiles into place and let them dry.

For the tile gaps, you may want to use caulk for added durability. This will ensure that everything is set.


Question: Can you tile directly onto concrete?
Answer: Yes, you can easily tile over concrete. However, keep in mind a few things. Make sure that the concrete is clean and there is no moisture seeping from it. If you find a few cracks, don’t forget to apply a layer of thin-set mortar to seal them in.

Question: How do you level a door threshold for concrete?
Answer: Sometimes when a concrete and tile floor meets, there is a difference in their heights. In most cases, the tile floor is elevated. To solve such a problem, you can install shims beneath the threshold. Next, apply a cement mix to fill the gaps between the shims. 

Question: How do you attach the threshold to concrete?
Answer: Other than thin-set mortar, you can use a masonry bit to make holes at all the screw fastening locations. Then insert your anchors and then set the screws.
