Shower Drain Lower Than Tiles? [Yes or No]

Home renovation is not a new thing. And this home renovation comes with washroom renovation. You want to change some specifications of your washroom. But suddenly noticed the shower drain is lower than the tiles.

Why is shower drain lower than tiles?

Yes, a shower drain should always be lower than the tiles. It’s because the dirty waters need to smoothly reach the drain. If there’s no slope, you’ll see standing water in your shower. That’s why the slope in the bathroom floor should be correctly done. You should determine shower drain height to correct the slope.

The above information is not all. We have elaborated on it in detail. All we need is 5 minutes of yours. Just read the blog till the end.

Let’s not stop here and continue reading!

Should A Shower Drain Be Equal To The Tiles?

The answer is no. A shower drain shouldn’t be equal to the tiles. The purpose of the drain is to pass the dirty water to the sewerage pipes. 

That’s why if they are at an equal height, the dirty water will not pass through it completely. Furthermore, the water will not be able to move anywhere. As a result, your shower will have standing water in it.

This way your shower floor will never get dry. This situation will definitely create a fungus and other types of bacteria on the floor. And the bathroom will also smell musty.

This is the main reason a shower drain should always be at a lower height. In almost every house, the drain remains lower than the whole washroom floor. This is why a shower drain shouldn’t be even equal to the tiles.

How To Correct Slope In Tile Bathroom Floor? 

You can’t correctly slope the bathroom floor yourself. An expert should do this for you. 

We recommend that the floor tiles are reviewed properly first. Then if necessary, relaid the tiles. This time maintaining an appropriate slope towards the floor drain outlet is important. 

Remember, there should be the adequate strengthening of the sealant at the floor and wall tile junction. You don’t want to lengthen the process even more, do you?

You should also be patient during the process. It can take a bit more time to retile your washroom than you’d imagine. 

How To Determine The Shower Drain Height? 

You can’t relaid the tiles and redo the entire thing yourself. But you can figure out the proper height of your shower drain. This info will be beneficial for you in the future too if there’s again any problem.

To determine the height of a tile shower drain just follow the steps we mentioned. We have used a simple approach done by professionals.

Step 1: Take Measurements of The Tiles

First, wear a pair of gloves. You should wear good quality gloves for this. You can use the similar pair of gloves used for applying teflon tape on your sprinkler heads

That’s why here are some suggestions-

Product 2

Got the gloves?

If yes, take measurements and make a note of the thickness of your tiles.  The thickness of ceramic tiles are usually 1/4 inch thick. 

But paver, sandstone, and marble tiles’ thickness can go up to 1/2 inch. Minor thickness variations are accommodated by the usage of thin-set mortar. This variation is done while placing the tiles.

Step 2: Determine How Thick The Mortar Is

It’s time to measure the mortar bed thickness. You should measure it before you lay the mortar bed. You do this at the point where it meets the shower drain. 

Now, because mortar beds are inclined to drainage, the outside areas are thicker. The standard shower floor slope is 4%. 

For better understanding, the mortar bed thickness should be 1/2 inch per every 12 inches. And of course, that is from the wall to the drain.

That’s why you must measure the thickness of the mortar bed.

Step 3: Determine Height Of The Drain

Incorporate the thickness of your mortar bed and tiles at the drain. Add 1/4 inch for the mortar bed’s paper. Then measure the drain on a 2-inch thick mortar bed. And the center in a 48-inch square shower tile will be one inch.

This way the drain’s height is determined.

By following the above three steps you can determine the shower drain height. 


Question: Is it necessary to have a level shower drain?

Answer: They are intended for vertical post accuracy rather than the sitting level on the ground. The shower drain is made up of several parts.

Question: What is the shower drain size code?

Answer: While a 2-inch drain pipe is typically required for a shower drain. The vent pipe must be either 1.5 inches or 2 inches in diameter. It depends on local regulations. Be careful to double-check this to ensure that the code in your region is correct.

Question: Is it okay to use a 1.5-inch pipe for the shower drain?

Answer: Yes, some states and towns only require a 1.5-inch shower drain pipe. But most common shower trays and pans are pre-wired for a two-inch pipe. That’s why you may not have much of a choice.


We hope now you know why a shower drain is lower than tiles.

If there’s no slope, do take help from a professional to fix it. If you’re trying to slope the bathroom, make sure you’re determining the drain height properly. 

Good luck and see you soon!
